PREVENTING FREE RADICAL DAMAGE WITH ULTIMATE PROTECTOR+

Back in 2012, I learned about Nrf2 activators and was excited about pursuing the development of a supplement that would incorporate the new knowledge we were learning into a effective product for preventing free radical damage. At that time, I published two articles: New Directions for Preventing Free Fadical Damage and Natural Phytochemical Nrf2 Activators for Chemoprevention. I started working on a new Nrf2-activator formula I called Ultimate Protector that incorporated many of the ideas contained in these articles. The product was introduced November 2012.

More recently, in early 2019, I decided to upgrade the product using new information and ingredients. The upgraded product is called Ultimate Protector+. In this article, I provide new details of our design logic and product ingredients. I expect the new formula to be released in July 2019.

Ultimate Protector+

Ultimate Protector+ is new and improved!

PREVENTING FREE RADICAL DAMAGE WITH ULTIMATE PROTECTOR+

Ultimate Protector+™ is a unique cell protection formula that simultaneously meets the needs for high levels of non-GMO Vitamin C, full spectrum antioxidants (high ORAC values), and protective enzyme activators (Nrf2 activators) in a single product. This potent combination of characteristics distinguishes the formula because no other single product available today offers such complete protection. This is the single best formula for preventing free radical damage that is available.

Ultimate Protector+™ provides extremely high levels of natural antioxidants, including high levels of ingredients such as polyphenols, flavonoids, anthocyanidins, oligomeric proanthocyanidins, catechins, curcuminoids, pterostilbene, resveratrol, chlorogenic acid, punicalagins, zeaxanthin and other carotenoids that act powerfully as antioxidants. These antioxidants come from more than 12 plant-based ingredients with demonstrated free-radical quenching capacity. These “exogenous” food-based antioxidants (supplied from outside the body) provide you with immense oxidative defenses that can be used to defend against free-radical assault.

Ultimate Protector+™ contains USP-grade non-GMO Vitamin C , SFB® standardized fruit blend (~50% polyphenols, high-ORAC powder: 9,000 µmole TE/g) from Grape, Cranberry, Pomegranate, Blueberry, Apple, Mangosteen, Bilberry, Chokeberry, and Goji Berry), Curcumin (standardized extract with 95% curcuminoids), Trans-Resveratrol (98% from Giant Knotweed), Green Tea Extract (90% polyphenols, 50% EGCG), VinCare® Whole Grape Extract (>80% polyphenols, ORAC>19,000 µmole TE/g), Calcium Malate, Magnesium Malate, and Bioperine® (a patented black pepper extract that enhances absorption of all ingredients and is a known Nrf2 activator).

Ultimate Protector+™ is contained in a capsule suitable for vegetarians (i.e., a veggie cap) and contains no magnesium stearate.

NUTRITIONAL CONSIDERATIONS AND APPLICATIONS

Ultimate Protector+™ satisfies three distinct needs:

1) The need for a non-GMO Vitamin C product. That is, a Vitamin C formula that avoids protein from genetically modified sources such as corn, potatoes, or beets.

2) The need for a single, powerful antioxidant formula for preventing free radical damage. That is, a single, easy-to-take antioxidant formula offering a broad range of extremely high-ORAC plant source antioxidants. These antioxidants should protect against the full range of free radicals found in the human body including: superoxide anion (O2·-), peroxyl radicals (ROO·), hydroxyl radicals (HO·), singlet oxygen (1O2), and peroxynitrite (ONOO-).

3) The need for a supplement providing a full spectrum of Nrf2 activators. That is, a supplement providing a wide range of natural Nrf2 transcription factor activators that allow the body to make its own antioxidant enzymes (e.g., superoxide dismutase (SOD), catalase, hemeoxygenase, and glutathione peroxidase). Scientific research has shown that these are found naturally in many fruits, vegetable, and herbs. These ingredients provide a wide range of Nrf2 activators that result in significantly high levels of the endogenously produced antioxidant enzymes.

The ways Ultimate Protector+™ satisfies these three needs are discussed below:

1) NON-GMO VITAMIN C / ASCORBIC ACID

High-quality, USP grade Vitamin C has been obtained historically from corn, potatoes, and/or beets. Unfortunately, many of these sources have to a large extent gone to genetically modified (GMO) variants. However, with highly refined production methods and the use of PCR testing, we have been able to obtain final products that are free from GMOs.

In nature, Vitamin C is found generally in plant sources containing polyphenols. Vitamin C and polyphenols work together to provide a high level of antioxidant protection and they support the function of each other in the process. For example, Vitamin C is needed by the body to produce collagen and certain polyphenols (especially oligomeric proanthocyanidins) (OPCs) crosslink the collagen and make it stronger.

2) EXTREMELY HIGH ORAC SOURCES

Free radicals are reactive species that can have adverse effects on normal physiological functions. Studies associate the five major types of free radicals (i.e., hydroxyl, peroxyl, peroxynitrite, singlet oxygen, and superoxide anion) with health conditions such as cardiovascular disease, hypertension, breakdown of vital proteins, chronic inflammation, Alzheimer’s disease, and certain cancers. Avoiding free radical damage is the goal.

Antioxidants function as a vital line of defense against free radicals by blocking their attack on DNA, vital proteins, lipids, and amino acids. Until now, efforts to identify the effect of antioxidants on all five types of free radicals were constrained by limited testing procedures. However, new technological developments have resulted in a comprehensive testing method called the Total ORAC5.0™ assay. Because of the development of the Total ORAC5.0™ test, it is now possible to target and measure the effects of antioxidants on the five major types of free radicals found in the body.

We are currently in the process of testing Ultimate Protector+™ using this new ORAC5.0™ assay. We are confident that our formula offers protection against these five major types of free-radicals because we combine a wide range of extremely high-ORAC fruit, vegetable, and herbal blends. As soon as the results are available (in July 2019), we will update this article with the findings.

3) NRF2 TRANSCRIPTION FACTOR ACTIVATORS

In order to survive under a variety of environmental or intracellular stresses, our cells have developed highly efficient protective mechanisms to protect themselves from oxidative or electrophilic challenges. Proteins that comprise phase II detoxification and antioxidant enzymes provide an enzymatic line of defense against reactive oxygen species (ROS). These enzymes include superoxide dismutase (SOD), catalase, glutathione peroxidase, glutathione S-transferase (GST), and glutamate cysteine ligase.

Induction of phase II and antioxidant enzymes are regulated at the DNA/gene level by an antioxidant responsive element (ARE). ARE-mediated gene expression plays a central role in the cellular defense against cellular oxidative damage. Experimental evidence supports the view that induction of ARE-mediated cytoprotective enzymes is a critical and sufficient mechanism to enable protection against disease provoked by environmental and endogenous insults.

One of the key ARE-binding transcription factors is Nrf2. Induction of cytoprotective enzymes in response to ROS, electrophiles, and phytochemicals is a cellular event that is highly dependent on Nrf2 protein. By activating Nrf2 signaling, phytochemicals can increase cellular detoxification and antioxidant enzymes, thereby enhancing removal of ROS and toxic chemicals and preventing disease. Numerous research studies carried out over the last 15 years have demonstrated the effectiveness of a very wide range of Nrf2 activators extracted from fruits, vegetables, and herbs.

For example, a study with sulforaphane (an isothiocyanate present abundantly in cruciferous vegetables) shows that oral administration of this phytochemical can effectively block benzo[a]pyrene-induced forestomach tumors in mice. This protective effect was abrogated in mice that could not produce Nrf2. This supports the critical role of phase II detoxification and antioxidant enzymes in the prevention of carcinogenesis by chemopreventive agents.

Nrf2 is normally bound in the cytoplasm of cells to a protein called KEAP1. However, when an appropriate phytochemical agent attaches to a kinase receptor on the cell wall a phosphate group is released that causes the Nrf2 to be released. Also, there are other mechanisms that allow Nrf2 to be released from KEAP1. The released Nrf2 then migrates into the cell nucleus and causes an antioxidant enzyme (e.g., superoxide dismutase (SOD)) to be fabricated and released. This endogenously produced enzyme then can protect against ROS, electrophiles, and other toxic agents.

In practical experience, it has been found that a combination of multiple polyphenols works significantly better than single ingredients. In fact, in one experiment it was found that a combination of five ingredients all known to be Nrf2 activators was 18 times more effective than any single ingredient. Furthermore, it was found that this combination of five ingredients was able to increase levels of SOD by 30% and catalase by 56% after 120 days of taking the combination.

In view of the considerations above, we include a wide range of Nrf2 activators in Ultimate Protector+™. These include a large variety of freeze-dried and concentrated fruits, vegetables, and herbs. These include Grape, Cranberry, Pomegranate, Blueberry, Apple, Mangosteen, Bilberry, Chokeberry, Goji Berry), Curcumin (standardized extract with 95% curcuminoids), Trans-Resveratrol (98% from Giant Knotweed), Green Tea Extract (93% polyphenols, 50% EGCG), VinCare® Whole Grape Extract (>80% polyphenols, ORAC>19,000 µmole TE/g)

Ultimate Protector+™ includes the following phytonutrients in its array of freeze-dried and concentrated fruits, vegetables, and herbs: polyphenols, flavonoids, anthocyanins, catechins, proanthocyanins, ellagic acid, xanthines, chlorogenic acid, pterostilbenes, resveratrol, phloridzin, quercetin, zeaxanthin, carotinoids, polysaccharides, quinic acid, and more.

The phytochemical ingredients in Ultimate Protector+™ are discussed below:

1. SFB® – (Standardized Fruit Blend)

SFB® is a nutritious, non-GMO blend that provides a broad spectrum of polyphenols, anthocyanins, and other antioxidants derived from water and/or ethanol extracts of grape (Vitis vinifera), cranberry (Vaccinium macrocarpon), pomegranate (Punica granatum) with >75% polyphenols, blueberry (Vaccinium uliginosum), apple (Malus pumilla Mill), mangosteen (Garcinia mangostana), bilberry (Vaccinium myrtillis), chokeberry (Aronia arbutifolia), and goji berry (Lycium barbarum). This powder has an ORAC value in excess of 9,000 µmole TE/g and contains 50% polyphenols.

Polyphenols and anthocyanins are not all created equal. Every fruit, vegetable and herb provides its own set of unique polyphenols and anthocyanins that reside in the body for different lengths of time and in different locations, providing a range of benefits. SFB® has been designed to provide a wide range of plant polyphenols, flavonoids, anthocyanins, catechins, OPCs, zeaxanthin and other carotinoids, etc. Published research associates these plant ingredients with healthy aging, inflammation management, improved blood sugar metabolism, and cardiovascular disease management.

SFB® provides the following benefits: Superior source of natural antioxidants and Nrf2 activators, helps ameliorate the effects of premature aging, promotes cardiovascular health, promotes healthy brain function and mental acuity, promotes healthy vision, promotes healthy blood sugar levels, and is an excellent source of flavonoids and organic acids.

I have prepared detailed blog articles for the ingredients in SFB®. Below some of these are summarized and links to the articles are provided.

a) Cranberry Extract

Ultimate Protector+ Includes Cranberry

Ultimate Protector+ Includes Cranberry Extract

Cranberry extract is an especially good source of antioxidant polyphenols. In animal studies, the polyphenols in cranberries have been found to decrease levels of total cholesterol and so-called “bad” cholesterol. Cranberries may also inhibit the growth of tumors in human breast tissue and lower the risk of both stomach ulcers and gum disease.

Here is a list of the antioxidant and anti-inflammatory phytonutrients in found in cranberry extract.

Type of Phytonutrient Specific Molecules
Phenolic Acids hydroxybenzoic acids including vanillic acids;
—Phenolic Acids (cont.) hydroxycinnamic acids inculding caffeic,
—Phenolic Acids (cont.) coumaric, cinnamic, and ferulic acid
Proanthocyanidins epicatechin oligomers
Anthocyanins cyanidins, malvidins, and peonidins
Flavonoids quercetin, myricetin, kaempferol
Triterpenoids ursolic acid

OTHER CRANBERRY INFORMATION

    • Cranberries hold significantly high amounts of phenolic flavonoid phytochemicals called oligomeric proanthocyanidins (OPC’s). Scientific studies have shown that consumption of the berries have potential health benefits regarding cancer, aging and neurological diseases, inflammation, diabetes, and bacterial infections.
    • Antioxidant compounds in cranberry extract including OPC’s, anthocyanidin flavonoids, cyanidin, peonidin and quercetin may support cardiovascular health by counteracting against cholesterol plaque formation in the heart and blood vessels. Further, these compounds help the human body lower LDL cholesterol levels and increase HDL-good cholesterol levels in the blood.
    • Scientific studies show that cranberry juice consumption offers protection against gram-negative bacterial infections such as E.coli in the urinary system by inhibiting bacterial-attachment to the bladder and urethra.
    • It is known that cranberries turns urine acidic. This, together with the inhibition of bacterial adhesion helps prevent the formation of alkaline (calcium ammonium phosphate) stones in the urinary tract by working against proteus bacterial-infections.
    • In addition, the berries prevent plaque formation on the tooth enamel by interfering with the ability of the gram-negative bacterium, Streptococcus mutans, to stick to the surface. In this way cranberries helps prevent the development of cavities.
    • The berries are also good source of many vitamins like vitamin C, vitamin A, ß-carotene, lutein, zea-xanthin, and folate and minerals like potassium, and manganese.
  • Oxygen Radical Absorbance Capacity (ORAC) demonstrates cranberry at an ORAC score of 9584 µmol TE units per 100 g, one of the highest in the category of edible berries.

b) Pomegranate Extract

Ultimate Protector+ Includes Pomegranate

Ultimate Protector+ Includes Pomegranate

For thousands of years, the pomegranate has been extensively used as a source of food and medicine. Full of antioxidants, vitamin C and potassium, pomegranate has been used to control body weight, reduce cholesterol, fight against cell damage, and inhibit viral infections. Pomegranate extracts have anti-bacterial effects.

Pomegranates are rich in ellagic acid, gallic acid, lignans, polyphenols and other bioactive compounds, and have been shown to lower blood pressure and enhance vascular function. Furthermore, it can offset some of the negative effects of medications and chemicals. These compounds occur naturally in its peel, seeds, leaf and juice. The seeds are high in p-coumaric acid, plant sterols, tannins and fatty acids. In addition to their antihypertensive effects, they may help reduce blood sugar levels.

Pomegranate fruit is a rounded berry with a thick reddish skin covering approximately 200–1400 white to deep red or purple seeds. Pomegranate seeds are edible and hold strong antioxidant and anti-inflammatory properties due to their high content of hydrolysable tannins and anthocyanins. As compared to the antioxidant activity of vitamin E, β-carotene, and ascorbic acid, the pomegranate antioxidants appear unique due to combinations of a wide array of polyphenols, having a broader range of action against several types of free radicals. As compared to the recognized antioxidants in red wine and green tea, anthocyanins from pomegranate fruit possess significantly higher antioxidant activity.

Pomegranate has been used in various medicinal systems of medicine for the treatment and therapy of a multitude of diseases and ailments. In the ancient Indian medicinal system, i.e., in Ayurvedic medicine, the pomegranate was considered to be a whole pharmacy unto itself. It was recommended to be used as an antiparasitic agent and to treat diarrhea and ulcers. The medicinal properties of pomegranate have sparked significant interest in today’s scientific community as evidenced by the scientific research relating to health benefits of pomegranate that have been published in last few decades.

Studies have shown that pomegranate and its constituents can efficiently affect multiple signaling pathways involved in inflammation, cellular transformation, hyperproliferation, angiogenesis, initiation of tumorigenesis, and eventually suppressing the final steps of tumorigenesis and metastasis. The pomegranate constituents are shown to modulate transcription factors, pro-apoptotic proteins, anti-apoptotic proteins, cell cycle regulator molecules, protein kinases, cell adhesion molecules, pro-inflammatory mediators, and growth factors.

c) Chokeberry (Aronia)

Ultimate Protector+ Includes Chokeberry

Ultimate Protector+ Includes Chokeberry

HEALTH BENEFITS OF CHOKEBERRY (ARONIA)

Aronia melanocarpa (black chokeberry) has attracted scientific interest due to its deep purple, almost black pigmentation that arises from dense contents of polyphenols, especially anthocyanins. Total polyphenol content is 1752 mg per 100 g in fresh berries, anthocyanin content is 1480 mg per 100 g, and proanthocyanidin concentration is 664 mg per 100 g. These values are among the highest measured in plants to date.

The plant produces these pigments mainly in the leaves and skin of the berries to protect the pulp and seeds from constant exposure to ultraviolet radiation and production of free radicals. By absorbing UV rays in the blue-purple spectrum, leaf and skin pigments filter intense sunlight, serve antioxidant functions and thereby have a role assuring regeneration of the species.

Analysis of polyphenols in chokeberries has identified the following individual chemicals (among hundreds known to exist in the plant kingdom): cyanidin-3-galactoside, cyanidin-3-arabinoside, quercetin-3-glycoside, epicatechin, caffeic acid, delphinidin, petunidin, pelargonidin, peonidin, and malvidin.All these except caffeic acid are members of the flavonoid category of phenolics.

In a standard measurement of antioxidant strength, the oxygen radical absorbance capacity or ORAC, demonstrates aronia to have one of the highest values yet recorded for a fruit — 16,062 micro moles of Trolox Eq. per 100 g. The components contributing to this high measurement were both anthocyanins and proanthocyanidins, with the proanthocyanidin level “among the highest in foods”, which may explain their potent astringent taste.

d) Goji Berry

Ultimate Protector+ Includes Goji Berry

Ultimate Protector+ Includes Goji Berry

Goji Berries contain abundant polysaccharides (LBPs, comprising 5%–8% of the dried fruits), scopoletin (6-methoxy-7-hydroxycoumarin, also named chrysatropic acid, ecopoletin, gelseminic acid, and scopoletol), the glucosylated precursor, and stable vitamin C analog 2-O-β-D-glucopyranosyl-L-ascorbic acid, carotenoids (zeaxanthin and β-carotene), betaine, cerebroside, β-sitosterol, flavonoids, amino acids, minerals, and vitamins (in particular, riboflavin, thiamin, and ascorbic acid).

The predominant carotenoid is zeaxanthin, which exists mainly as dipalmitate (also called physalien or physalin). The content of vitamin C (up to 42 mg/100 g) in goji berry (also known as wolfberry) is comparable to that of fresh lemon fruits. As to the seeds, they contain zeaxanthin (83%), β-cryptoxanthin (7%), β-carotene (0.9%), and mutatoxanthin (1.4%), as well as some minor carotenoids.

In fact, increasing lines of experimental studies have revealed that L. barbarum berries have a wide array of pharmacological activities, which is thought to be mainly due to its high LBPs content. Water-soluble LBPs are obtained using an extraction process that removes the lipid soluble components such as zeaxanthin and other carotenoids with alcohol. LBPs are estimated to comprise 5%–8% of LBFs and have a molecular weight ranging from 24 kDa to 241 kDa. LBPs consist of a complex mixture of highly branched and only partly characterized polysaccharides and proteoglycans.

The glycosidic part accounts, in most cases, for about 90%–95% of the mass and consists of arabinose, glucose, galactose, mannose, rhamnose, xylose, and galacturonic acid. LBPs are considered the most important functional constituents in LBFs. Different fractions of LBPs have different activities and the galacturonic acid content is an imperative factor for activities of LBP. The bioactivities of polysaccharides are often in reverse proportion with their molecular weights. Increasing lines of evidence from both preclinical and clinical studies support the medicinal, therapeutic, and health-promoting effects of LBPs.

e) Mangosteen

Ultimate Protector+ Includes Mangosteen

Ultimate Protector+ Includes Mangosteen

The Mangosteen extract in Ultimate Protector+ has been extracted with non-GMO food grade ethanol and distilled water. Testing has indicated the product contains over 10% polyphenols.

Mangosteen extract in obtained from the skin and whole fruit for which numerous biological activities have been reported including: antimutagenic, antibacterial, hypocholesterolemic, antioxidant, and protective against tumorigenesis.

Mangosteen contains nutrients with antioxidant capacity, such as vitamin C and folate. Plus, it provides xanthones — a unique type of plant compound known to have strong antioxidant properties. In several test-tube and animal studies, the antioxidant activity of xanthones has resulted in anti-inflammatory, anticancer, anti-aging, heart protective, and antidiabetic effects.

Additionally, some research suggests that certain plant compounds in mangosteen may have antibacterial properties — which could benefit your immune health by combating potentially harmful bacteria. In a 30-day study in 59 people, those taking a mangosteen-containing supplement experienced reduced markers of inflammation and significantly greater increases in healthy immune cell numbers compared to those taking a placebo.

f) Apple Extract

Ultimate Protector+ Includes Apple

Apples contain a large concentration of flavonoids, as well as a variety of other phytochemicals, and the concentration of these phytochemicals may depend on many factors, such as cultivar of the apple, harvest and storage of the apples, and processing of the apples. The concentration of phytochemicals also varies greatly between the apple peels and the apple flesh.

Some of the most well studied antioxidant compounds in apples include quercetin-3-galactoside, quercetin-3-glucoside, quercetin-3-rhamnoside, catechin, epicatechin, procyanidin, cyanidin-3-galactoside, coumaric acid, chlorogenic acid, gallic acid, and phloridzin. Recently researchers have examined the average concentrations of the major phenolic compounds in six cultivars of apples. They found that the average phenolic concentrations among the six cultivars were: quercetin glycosides, 13.2 mg/100 g fruit; vitamin C, 12.8 mg/100 g fruit; procyanidin B, 9.35 mg/100 g fruit; chlorogenic acid, 9.02 mg/100 g fruit; epicatechin, 8.65 mg/100 g fruit; and phloretin glycosides, 5.59 mg/100 g fruit.

The compounds most commonly found in apple peels consist of the procyanidins, catechin, epicatechin, chlorogenic acid, phloridzin, and the quercetin conjugates. In the apple flesh, there is some catechin, procyanidin, epicatechin, and phloridzin, but these compounds are found in much lower concentrations than in the peels. Quercetin conjugates are found exclusively in the peel of the apples. Chlorogenic acid tends to be higher in the flesh than in the peel.

Because the apple peels contain more antioxidant compounds, especially quercetin, apple peels may have higher antioxidant activity and higher bioactivity than the apple flesh. Research showed that apples without the peels had less antioxidant activity than apples with the peels. Apples with the peels were also better able to inhibit cancer cell proliferation when compared to apples without the peels. More recent work has shown that apple peels contain anywhere from two to six times (depending on the variety) more phenolic compounds than in the flesh, and two to three times more flavonoids in the peels when compared to the flesh. The antioxidant activity of these peels was also much greater, ranging from two to six times greater in the peels when compared to the flesh, depending on the variety of the apple. This work is supported a study which found that rats consuming apple peels showed greater inhibition of lipid peroxidation and greater plasma antioxidant capacity when compared to rats fed apple flesh.

Many of these phytochemicals from apples have been widely studied, and many potential health benefits have been attributed to these specific phytochemicals. The procyanidins, epicatechin and catechin, have strong antioxidant activity and have been found to inhibit low density lipoprotein (LDL) oxidation in vitro. In mice, catechin inhibits intestinal tumor formation and delays tumors onset. One study found that chlorogenic acid has very high alkyl peroxyl radical (ROO•) scavenging activity. Compared to about 18 other antioxidant compounds (including quercetin, gallic acid, α-tocopherol), chlorogenic was second only to rutin. Since ROO• may enhance tumor promotion and carcinogenesis, chlorogenic acid may add to the protective effect of apples against cancer. Chlorogenic acid has been found to inhibit 8-dehydroxy-deoxyguanosine formation in cellular DNA in a rat model following treatment with 4-nitroquinoline-1-oxide.

Quercetin is also a strong antioxidant, and is thought to have potential protective effects against both cancer and heart disease. Briefly, quercetin has been found to down regulate expression of mutant p53 in breast cancer cells, arrest human leukemic T-cells in G1, inhibit tyrosine kinase, and inhibit heat shock proteins. Quercetin has protected Caco-2 cells from lipid peroxidation induced by hydrogen peroxide and Fe2+. In mice liver treated with ethanol, quercetin decreased lipid oxidation and increased glutathione, protecting the liver from oxidative damage. Recently, it has been found that high doses of quercetin inhibit cell proliferation in colon carcinoma cell lines and in mammary adenocarcinoma cell lines, but at low doses quercetin increased cell proliferation (20% in colon cancer cells and 100% in breast cancer cells). However, low doses of quercetin (10 uM) inhibited cell proliferation in Mol-4 Human Leukemia cells and also induced apoptosis. Quercetin inhibited intestinal tumor growth in mice, but not in rats. Low levels of quercetin inhibited platelet aggregation, calcium mobilization, and tyrosine protein phosphorylation in platelets. Modulation of platelet activity may help prevent cardiovascular disease.

g) Blueberry and Bilberry Extract

wild bilberry and wild blueberry
Wild bilberry and wild blueberry provide Nrf2 activators.

The key compounds in bilberry fruit are called anthocyanins and anthocyanosides. These compounds help build strong blood vessels and improve circulation to all areas of the body. They also prevent blood platelets from clumping together (helping to reduce the risk of blood clots), and they have antioxidant properties (preventing or reducing damage to cells from free radicals). Anthocyanins boost the production of rhodopsin, a pigment that improves night vision and helps the eye adapt to light changes.

Bilberry fruit is also rich in tannins, a substance that acts as an astringent. The tannins have anti-inflammatory properties and may help control diarrhea.

Bilberries have been shown to have the highest Oxygen Radical Absorbance Capacity (ORAC) rating of more than 20 fresh fruits and berries. The antioxidant properties of bilberries were shown to be even stronger than those of cranberries, raspberries, strawberries, plums, or cultivated blueberries.

The antioxidant powers and health benefits of bilberries and blueberries can be attributed to a number of remarkable compounds contained in them, including the following:

  • Anthocyanins
    • malvidins
    • delphinidins
    • pelargonidins
    • cyanidins
    • peonidins
  • Hydroxycinnamic acids
    • caffeic acids
    • ferulic acids
    • coumaric acids
  • Hydroxybenzoic acids
    • gallic acids
    • procatchuic acids
  • Flavonols
    • kaempferol
    • quercetin
    • myricetin
  • Other phenol-related phytonutrients
    • pterostilbene
    • resveratrol
  • Other nutrients
    • lutein
    • zeaxanthin
    • Vitamin K
    • Vitamin C
    • manganese

2) Curcumin

Ultimate Protector+ Includes Curcumin

Ultimate Protector+ Includes Curcumin

We have included Curcumin (95% curcuminoids in ULTIMATE PROTECTOR™. This ingredient contains three main chemical compounds – Curcumin, Demethoxycurcumin and Bisdemethoxycurcumin – collectively known as Curcuminoids and all derived from Turmeric. Curcumin has been shown to be one of the most potent Nrf2 transcription factor activators. Studies have reported that curcumin and turmeric protect the liver against several toxicants both in vitro and in vivo. A number of reports showed the curative action of turmeric and curcuminoids. Curcumin is a potent scavenger of free radicals such as superoxide anion radicals, hydroxyl radicals, and nitrogen dioxide radicals. It exerts powerful antioxidant and anti-inflammatory properties.


3) Trans-Resveratrol (98% from Polygonum cuspidatum – giant knotweed)

giant knotweed resveratrol

Knotweed (Polygonum cuspidatum) is a major source for resveratrol.

Trans-resveratrol provides antioxidant protection, boosts cellular energy, and balances the immune system. It has been proven in studies to activate the SIRT1 longevity gene and enhance cellular productivity. Several research studies have shown that trans-resveratrol activates Nrf2 transcription factor, significantly modulates biomarkers of bone metabolism, inhibits pro-inflammatory enzymes such as COX-1 and COX-2, and exhibits cardioprotective effects, neuroprotective properties, and caloric restrictive behavior. Trans-resveratrol has shown the ability to increase the number of mitochondria thereby increasing total daily energy. Studies have shown that trans-resveratrol promotes an increase in mitochondrial function. Increased mitochondrial function translates into an increase in energy availability, improved aerobic capacity, and enhanced sensorimotor function. Trans-resveratrol has an ORAC value of 31,000 µmole TE/g.


4) Green Tea Extract

Ultimate Protector+ Includes Green Tea Extract

Ultimate Protector+ Includes Green Tea Extract

Green Tea Extract contains highly bioavailable bioflavonoid complexes that in research studies have been shown to have powerful antioxidant capability. Green tea extract is obtained from the unfermented leaves of Camellia sinensis for which numerous biological activities have been reported including: cell protective, antimicrobial, and antioxidant. The green tea extract in Ultimate Protector is extracted is extracted by non-GMO ethanol and distilled water and contains ~ 90% polyphenols and 50% epigallocatechingallate (EGCG).

Epigallocatechin gallate (EGCG) is the most abundant catechin compound in green tea. It is well established that EGCG is a potent antioxidant and anti-inflammatory agent. Epidemiological studies show that consumption of 100 or more mg of EGCG per day is beneficial, as it is the most potent Nrf2 activator among all green tea catechins. EGCG exhibits robust diffusion through bodily tissues, including the endothelium of the blood brain barrier.

EGCG has the capacity to activate Nrf2/ARE and induce Heme oxygenase-1 (HO-1) expression. Several studies have shown that EGCG can also interact with kinases, causing the disassociation of Nrf2/Keap1 complex.

Protective effects of EGCG have been reported against ischemia/reperfusion injury. Administration of EGCG showed improved neurologic scores, reduced infarct volume, and ameliorated neuronal apoptosis due to increased GSH biosynthesis (via Nrf2 activation) and decreased ROS content. By inducing the expression of Nrf2 and HO-1, EGCG increases important endogenous antioxidants in microglial cells.

5) VinCare® whole grape extract (seed, pulp, and skin)

Ultimate Protector+ Includes Whole Grape Extract

Ultimate Protector+ Includes Whole Grape Extract

Whole Grape Extract contains highly bioavailable bioflavonoid complexes that in research studies have been shown to have powerful antioxidant capability. The Oligomeric Proanthocyanidins (OPCs) in grape extract are able to strengthen collagen fibers in aging or damaged connective tissue and can act as a preventative against connective tissue degradation. Some research indicates that anthocyanidins, which are found in extracts of grape seed, skin, and stems (but not in grape seed extract), can reduce oxidized glutathione while at the same time become reduced themselves. In addition, extracts of grape skin and pulp (but not those of grape seed extract) contain trans-resveratrol that has been shown to have cell protective effects.

Grape seed extract has been reported to demonstrate a remarkable spectrum of biological, pharmacological and therapeutic properties against oxidative stress. The antioxidative activities of grape seed extract have been found to be much stronger than those of vitamins C and E. Studies have indicated that grape seed extract showed a protective effect on cardiovascular disease, nephropathy, atherosclerosis, and neuropathy, among other conditions.

Vincare® contains ~80% polypnenols and has an ORAC value of about 19,000 µmole TE/g. ORAC 5.0 testing of grape seed extract exhibits one of the highest values of any tested material at about 100,000 µmole TE/g.

It has been shown that grape seed OPCs activate nuclear erythroid2-related factor2 (Nrf2), which is a key antioxidative transcription factor, with the concomitant elevation of downstream hemeoxygenase-1 (HO-1).

Ultimate Protector+ Includes Resveratrol

Resveratrol (3,5,4′-trihydroxy-trans-stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin produced naturally by several plants in response to injury or when the plant is under attack by pathogens such as bacteria and fungi. Natural sources of resveratrol include giant knotweed (Polygonum cuspidatum) and the skin of grapes, blueberries, raspberries, and mulberries. Resveratrol has two isomers: cis and trans, with the latter being the most abundant.  Piceid, also known as polydatin, is a glucoside form of resveratrol found in Japanese knotweed. HPDI includes the very pure 98% resveratrol form from giant knotweed in Ultimate Protector+. This material contains greater than 96% of the trans form.

Knotweed (Polygonum cuspidatum) is a major source for resveratrol

VinCare® Whole Grape Extract

VinCare® Whole Grape Extract (seed, pulp, & skin) contains highly bioavailable bioflavonoid complexes that in research studies have been shown to have powerful antioxidant capability. The Oligomeric Proanthocyanidins (OPCs) in grape extract are able to strengthen collagen fibers in aging or damaged connective tissue and can act as a preventative against connective tissue degradation. Some research indicates that anthocyanidins, which are found in extracts of grape seed, skin, and stems (but not in grape seed extract), can reduce oxidized glutathione while at the same time become reduced themselves. In addition, extracts of grape skin and pulp (but not those of grape seed extract) contain trans-resveratrol that has been shown to have cell protective effects.

Vincare® contains >80% polyphenols and has an ORAC value of about 19,000 µmole TE/g. ORAC 5.0 testing of grape seed extract exhibits one of the highest values of any tested material at about 100,000 µmole TE/g.

It has been shown that grape seed OPCs activate nuclear erythroid2-related factor2 (Nrf2), which is a key antioxidative transcription factor, with the concomitant elevation of downstream hemeoxygenase-1 (HO-1). Click here to view an excellent article entitled Proanthocyanidins [OPCs] against Oxidative Stress: From Molecular Mechanisms to Clinical Applications.

HEALTH BENEFITS OF RESVERATROL

Resveratrol provides anti-oxidant protection, boosts cellular energy, and balances the immune system. It has been proven in studies to activate the SIRT1 longevity gene and enhance cellular productivity. Several research studies have shown that trans-resveratrol significantly modulates biomarkers of bone metabolism, inhibits pro-inflammatory enzymes such as COX-1 and COX-2, and exhibits chemopreventive properties, cardioprotective effects, neuroprotective properties, and caloric restrictive behavior. Trans-resveratrol has shown the ability to increase the number of mitochondria thereby increasing total daily energy. Studies have shown that trans-resveratrol promotes an increase in mitochondrial function, that translates into an increase in energy availability, improved aerobic capacity, and enhanced sensorimotor function. Resveratrol has been shown to be a powerful Nrf2 activator that can support the body’s endogenous production of protective enzymes.

Resveratrol confers endothelial protection via activation of the antioxidant transcription factor Nrf2.

Abstract

Epidemiological studies suggest that Mediterranean diets rich in resveratrol are associated with reduced risk of coronary artery disease. Resveratrol was also shown to confer vasoprotection in animal models of type 2 diabetes and aging. However, the mechanisms by which resveratrol exerts its antioxidative vasculoprotective effects are not completely understood. Using a nuclear factor-E(2)-related factor-2 (Nrf2)/antioxidant response element-driven luciferase reporter gene assay, we found that in cultured coronary arterial endothelial cells, resveratrol, in a dose-dependent manner, significantly increases transcriptional activity of Nrf2. Accordingly, resveratrol significantly upregulates the expression of the Nrf2 target genes NAD(P)H:quinone oxidoreductase 1, gamma-glutamylcysteine synthetase, and heme oxygenase-1. Resveratrol treatment also significantly attenuated high glucose (30 mM)-induced mitochondrial and cellular oxidative stress (assessed by flow cytometry using MitoSox and dihydroethidine staining). The aforementioned effects of resveratrol were significantly attenuated by the small interfering RNA downregulation of Nrf2 or the overexpression of Kelch-like erythroid cell-derived protein 1, which inactivates Nrf2. To test the effects of resveratrol in vivo, we used mice fed a high-fat diet (HFD), which exhibit increased vascular oxidative stress associated with an impaired endothelial function. In HFD-fed Nrf2(+/+) mice, resveratrol treatment attenuates oxidative stress (assessed by the Amplex red assay), improves acetylcholine-induced vasodilation, and inhibits apoptosis (assessed by measuring caspase-3 activity and DNA fragmentation) in branches of the femoral artery. In contrast, the aforementioned endothelial protective effects of resveratrol were diminished in HFD-fed Nrf2(-/-) mice. Taken together, our results indicate that resveratrol both in vitro and in vivo confers endothelial protective effects which are mediated by the activation of Nrf2.

Mitochondrial Protection by Resveratrol

From: http://www.medscape.com/viewarticle/745451

Abstract

Mitochondrial dysfunction and oxidative stress are thought to play important roles in mammalian aging. Resveratrol is a plant-derived polyphenol that exerts diverse antiaging activities, mimicking some of the molecular and functional effects of dietary restriction. This review focuses on the molecular mechanisms underlying the mitochondrial protective effects of resveratrol, which could be exploited for the prevention or amelioration of age-related diseases in the elderly.

Introduction

Age-specific mortality rates from heart disease, stroke, complications of diabetes, Alzheimer disease, and cancer increase exponentially with age, which imposes a huge financial burden on the health care systems in the Western world. There is an urgent need for effective therapeutic strategies that have the potential to promote health in the elderly, simultaneously preventing or delaying the development of various diseases of aging. During the past decade, dietary supplementation with resveratrol (3,5,4′-trihydroxystilbene) has emerged as a promising approach to counteract age-related diseases. Resveratrol is a naturally occurring polyphenol found in more than 70 species of plants, including grapes (Vitis vinifera), cranberries (Vaccinium macrocarpon), and peanuts (Arachis hypogaea), which was shown to confer diverse physiological effects in laboratory animals including cancer protection, microvascular protection, neuroprotection, cardioprotection, and antidiabetic effects. In this review, we consider the evidence in support of the hypothesis that mitochondrial protective effects of resveratrol underlie its antiaging action that can prevent/delay the development of age-related diseases in the cardiovascular system and other organs. The use of resveratrol as a dietary supplement to promote mitochondrial health in the elderly and diabetic patients is discussed.

Resveratrol induces glutathione synthesis by activation of Nrf2 and protects against cigarette smoke-mediated oxidative stress in human lung epithelial cells

From: http://ajplung.physiology.org/content/294/3/L478 

Abstract

Nuclear erythroid-related factor 2 (Nrf2), a redox-sensitive transcription factor, is involved in transcriptional regulation of many antioxidant genes, including glutamate-cysteine ligase (GCL). Cigarette smoke (CS) is known to cause oxidative stress and deplete glutathione (GSH) levels in alveolar epithelial cells. We hypothesized that resveratrol, a polyphenolic phytoalexin, has antioxidant signaling properties by inducing GSH biosynthesis via the activation of Nrf2 and protects lung epithelial cells against CS-mediated oxidative stress. Treatment of human primary small airway epithelial and human alveolar epithelial (A549) cells with CS extract (CSE) dose dependently decreased GSH levels and GCL activity, effects that were associated with enhanced production of reactive oxygen species. Resveratrol restored CSE-depleted GSH levels by upregulation of GCL via activation of Nrf2 and also quenched CSE-induced release of reactive oxygen species. Interestingly, CSE failed to induce nuclear translocation of Nrf2 in A549 and small airway epithelial cells. On the contrary, Nrf2 was localized in the cytosol of alveolar and airway epithelial cells due to CSE-mediated posttranslational modifications such as aldehyde/carbonyl adduct formation and nitration. On the other hand, resveratrol attenuated CSE-mediated Nrf2 modifications, thereby inducing its nuclear translocation associated with GCL gene transcription, as demonstrated by GCL-promoter reporter and Nrf2 small interfering RNA approaches. Thus resveratrol attenuates CSE-mediated GSH depletion by inducing GSH synthesis and protects epithelial cells by reversing CSE-induced posttranslational modifications of Nrf2. These data may have implications in dietary modulation of antioxidants in treatment of chronic obstructive pulmonary disease.

Effect of Nrf2 activators on release of glutathione, cysteinylglycine and homocysteine by human U373 astroglial cells

From: http://www.sciencedirect.com/science/article/pii/S2213231713000645

Abstract

Neurons rely on the release and subsequent cleavage of GSH to cysteinylglycine (CysGly) by astrocytes in order to maintain optimal intracellular GSH levels. In neurodegenerative diseases characterised by oxidative stress, neurons need an optimal GSH supply to defend themselves against free radicals released from activated microglia and astroglia. The rate of GSH synthesis is controlled largely by the activity of γ-glutamyl cysteine ligase. Expression of γ-glutamyl cysteine ligase and of the Xc- system, which facilitates cystine uptake, is regulated by the redox-sensitive transcription factor, nuclear factor erythroid-2-related factor 2 (Nrf2). Compounds that can activate the Nrf2-ARE pathway, referred to as ‘Nrf2 activators’ are receiving growing attention due to their potential as GSH-boosting drugs.

This study compares four known Nrf2 activators, R-α-Lipoic acid (LA), tert-butylhydroquinone (TBHQ), sulforaphane (SFN) and Polygonum cuspidatum extract containing 50% resveratrol (PC-Res) for their effects on astroglial release of GSH and CysGly. GSH levels increased dose-dependently in response to all four drugs. Sulforaphane produced the most potent effect, increasing GSH by up to 2.4-fold. PC-Res increased GSH up to 1.6-fold, followed by TBHQ (1.5-fold) and LA (1.4-fold). GSH is processed by the ectoenzyme, γ-glutamyl transpeptidase, to form CysGly. Once again, SFN produced the most potent effect, increasing CysGly by up to 1.7-fold, compared to control cells. TBHQ and PC-Res both induced fold increases of 1.3, followed by LA with a fold increase of 1.2. The results from the present study showed that sulforaphane, followed by lipoic acid, resveratrol and Polygonum multiflorum were all identified as potent “GSH and Cys-Gly boosters”.

Resveratrol Upregulates Nrf2 Expression To Attenuate Methylglyoxal-Induced Insulin Resistance in Hep G2 Cells

From: http://pubs.acs.org/doi/abs/10.1021/jf302831d

Abstract

Oxidative stress can result in insulin resistance, a primary cause of type-2 diabetes. Methylglyoxal (MG), a highly reactive dicarbonyl metabolite generated during glucose metabolism, has also been confirmed to cause pancreatic injury and induce inflammation, thereby resulting in insulin resistance. Recently, resveratrol has been reported to exert antioxidant properties, protecting cells from the generation of reactive oxygen species (ROS). The aim of this study was to evaluate resveratrol activation of nuclear factor erythroid 2-related factor 2 (Nrf2) to attenuate MG-induced insulin resistance in Hep G2 cells. Therefore, the molecular signaling events affecting resveratrol-mediated heme oxygenase-1 (HO-1) and glyoxalase expression levels were further investigated in this study. Our findings indicated that resveratrol activated the extracellular signal-regulated kinase (ERK) pathway but not the p38 or c-Jun N-terminal kinase (JNK) pathways, subsequently leading to Nrf2 nuclear translocation and elevation of HO-1 and glyoxalase expression levels. Moreover, resveratrol significantly elevated glucose uptake and protected against MG-induced insulin resistance in Hep G2 cells. In contrast, depletion of Nrf2 by small interfering RNA (si-RNA) resulted in the abrogation of HO-1 and glyoxalase expression in the MG-treated resveratrol group in Hep G2 cells. Administration of an appropriate chemopreventive agent, such as resveratrol, may be an alternative strategy for protecting against MG-induced diabetes.

Resveratrol restores sirtuin 1 (SIRT1) activity and pyruvate dehydrogenase kinase 1 (PDK1) expression after hemorrhagic injury in a rat model.

From: http://www.ncbi.nlm.nih.gov/pubmed/24395567

 Abstract

Severe hemorrhage leads to decreased blood flow to tissues resulting in decreased oxygen and nutrient availability affecting mitochondrial function. A mitoscriptome profiling study demonstrated alteration in several genes related to mitochondria, consistent with the mitochondrial functional decline observed after trauma hemorrhage (T-H). Our experiments led to the identification of sirtuin 1 (SIRT1) as a potential target in T-H. Administration of resveratrol (a naturally occurring polyphenol and activator of SIRT1) after T-H improved left ventricular function and tissue ATP levels. Our hypothesis was that mitochondrial function after T-H depends on SIRT1 activity. In this study, we evaluated the activity of SIRT1, a mitochondrial functional modulator, and the mitochondrial-glycolytic balance after T-H. We determined the changes in protein levels of pyruvate dehydrogenase kinase (PDK)-1 and nuclear c-Myc, peroxisome proliferator-activated receptor-γ coactivator (PGC)-1α and NF-E2-related factor (NRF)2 after T-H and after treatment with resveratrol or a combination of sirtinol (a SIRT1 inhibitor) and resveratrol. We have also tested the activity of mitochondrial complex 1. SIRT1 enzyme activity was significantly decreased after T-H, whereas resveratrol treatment restored the activity. We found elevated PDK1 and c-Myc levels and decreased PGC-1α, NRF2 and mitochondrial complex I activity after T-H. The reduced SIRT1 activity after T-H may be related to declining mitochondrial function, since resveratrol was able to reinstate SIRT1 activity and mitochondrial function. The elevated level of PDK1 (an inhibitor of pyruvate dehydrogenase complex) after T-H indicates a possible shift in cellular energetics from mitochondria to glycolysis. In conclusion, SIRT1 modulation alters left ventricular function after T-H through regulation of cellular energetics.

Resveratrol suppresses PAI-1 gene expression in a human in vitro model of inflamed adipose tissue.

From: http://www.ncbi.nlm.nih.gov/pubmed/23819014

 Abstract

Increased plasminogen activator inhibitor-1 (PAI-1) levels are associated with a number of pathophysiological complications; among them is obesity. Resveratrol was proposed to improve obesity-related health problems, but the effect of resveratrol on PAI-1 gene expression in obesity is not completely understood. In this study, we used SGBS adipocytes and a model of human adipose tissue inflammation to examine the effects of resveratrol on the production of PAI-1. Treatment of SGBS adipocytes with resveratrol reduced PAI-1 mRNA and protein in a time- and concentration-dependent manner. Further experiments showed that obesity-associated inflammatory conditions lead to the upregulation of PAI-1 gene expression which was antagonized by resveratrol. Although signaling via PI3K, Sirt1, AMPK, ROS, and Nrf2 appeared to play a significant role in the modulation of PAI-1 gene expression under noninflammatory conditions, those signaling components were not involved in mediating the resveratrol effects on PAI-1 production under inflammatory conditions. Instead, we demonstrate that the resveratrol effects on PAI-1 induction under inflammatory conditions were mediated via inhibition of the NF κ B pathway. Together, resveratrol can act as NF κ B inhibitor in adipocytes and thus the subsequently reduced PAI-1 expression in inflamed adipose tissue might provide a new insight towards novel treatment options of obesity.

Effects of resveratrol in experimental and clinical non-alcoholic fatty liver disease.

From: http://www.ncbi.nlm.nih.gov/pubmed/24799987

 Abstract

The prevalence of obesity and related conditions like non-alcoholic fatty liver disease (NAFLD) is increasing worldwide and therapeutic options are limited. Alternative treatment options are therefore intensively sought after. An interesting candidate is the natural polyphenol resveratrol (RSV) that activates adenosinmonophosphate-activated protein kinase (AMPK) and silent information regulation-2 homolog 1 (SIRT1). In addition, RSV has known anti-oxidant and anti-inflammatory effects. Here, we review the current evidence for RSV-mediated effects on NAFLD and address the different aspects of NAFLD and non-alcoholic steatohepatitis (NASH) pathogenesis with respect to free fatty acid (FFA) flux from adipose tissue, hepatic de novo lipogenesis, inadequate FFA β-oxidation and additional intra- and extrahepatic inflammatory and oxidant hits. We review the in vivo evidence from animal studies and clinical trials. The abundance of animal studies reports a decrease in hepatic triglyceride accumulation, liver weight and a general improvement in histological fatty liver changes, along with a reduction in circulating insulin, glucose and lipid levels. Some studies document AMPK or SIRT1 activation, and modulation of relevant markers of hepatic lipogenesis, inflammation and oxidation status. However, AMPK/SIRT1-independent actions are also likely. Clinical trials are scarce and have primarily been performed with a focus on overweight/obese participants without a focus on NAFLD/NASH and histological liver changes. Future clinical studies with appropriate design are needed to clarify the true impact of RSV treatment in NAFLD/NASH patients.

Modulatory role of resveratrol on cytotoxic activity of cisplatin, sensitization and modification of cisplatin resistance in colorectal cancer cells.

From: http://www.ncbi.nlm.nih.gov/pubmed/25815689

 Abstract

Colorectal cancer (CRC) is a leading cause of cancer-associated mortality worldwide. Cisplatin (CIS) is one of the most active cytotoxic agents in current use and it has proven efficacy against various human malignancies. However, its clinical usefulness has been restricted by detrimental side effects, including nephrotoxicity and myelosuppression. The aim of the present study was to attempt to decrease the required dose of CIS, in order to minimize its side effects, and increase its capability to arrest, delay or reverse carcinogenesis. In addition, the present study aimed to ameliorate CIS‑resistance in CRC cells, using the natural compound resveratrol (RSVL). RSVL (3,4′, 5‑trihydroxy‑trans‑stilbene) is a naturally occurring polyphenol present in the roots of white hellebore (Veratrum grandiflorum O. Loes) and extracted from >70 other plant species. RSVL can exert antioxidant and anti‑inflammatory activities, and it has been shown to be active in the regulation of numerous cellular events associated with carcinogenesis. The present study evaluated the effects of RSVL on sensitization of both parent and CIS‑resistant HCT‑116 CRC cells to the action of cisplatin. The CIS was administered at a dose of 5 and 20 µg/ml, and CIS cytotoxicity, apoptosis, cell cycle and cisplatin cellular uptake were examined in the presence and absence of RSVL (15 µg/ml). RSVL treatment showed anti‑proliferative effects and enhanced the cytotoxic effects of cis against the growth of both parent and CIS‑resistant HCT‑116 CRC cells, with a half maximal inhibitory concentration of 4.20 µg/ml and 4.72 µg/ml respectively. RSVL also induced a significant increase in the early apoptosis fraction and enhanced the subsequent apoptotic effects of CIS. The cellular uptake of CIS was significantly increased in the presence of RSVL, as compared with CIS treatment alone, and RSVL treatment sensitized the CIS‑resistant HCT‑116 cells. In conclusion, RSVL treatment increased the cytotoxic activity of CIS against the growth of both parent and CIS‑resistant HCT-116 CRC cells.

Resveratrol treatment rescues hyperleptinemia and improves hypothalamic leptin signaling programmed by maternal high-fat diet in rats.

From: http://www.ncbi.nlm.nih.gov/pubmed/25801629

 Abstract

PURPOSE: Perinatal high-fat diet is associated with obesity and metabolic diseases in adult offspring. Resveratrol has been shown to exert antioxidant and anti-obesity actions. However, the effects of resveratrol on leptinemia and leptin signaling are still unknown as well as whether resveratrol treatment can improve metabolic outcomes programmed by maternal high-fat diet. We hypothesize that resveratrol treatment in male rats programmed by high-fat diet would decrease body weight and food intake, and leptinemia with changes in central leptin signaling.

METHODS: Female Wistar rats were divided into two groups: control group (C), which received a standard diet containing 9 % of the calories as fat, and high-fat group (HF), which received a diet containing 28 % of the calories as fat. Dams were fed in C or HF diet during 8 weeks before mating and throughout gestation and lactation. C and HF male offspring received standard diet throughout life. From 150 until 180 days of age, offspring received resveratrol (30 mg/Kg body weight/day) or vehicle (carboxymethylcellulose).

RESULTS: HF offspring had increased body weight, hyperphagia and increased subcutaneous and visceral fat mass compared to controls, and resveratrol treatment decreased adiposity. HF offspring had increased leptinemia as well as increased SOCS3 in the arcuate nucleus of the hypothalamus, which suggest central leptin resistance. Resveratrol treatment rescued leptinemia and increased p-STAT3 content in the hypothalamus with no changes in SOCS3, suggesting improvement in leptin signaling.

CONCLUSIONS: Collectively, our data suggest that resveratrol could reverse hyperleptinemia and improve central leptin action in adult offspring from HF mothers attenuating obesity.

Resveratrol induces glutathione synthesis by activation of Nrf2 and protects against cigarette smoke-mediated oxidative stress in human lung epithelial cells

Thus resveratrol attenuates CSE-mediated GSH depletion by inducing GSH synthesis and protects epithelial cells by reversing CSE-induced posttranslational modifications of Nrf2. These data may have implications in dietary modulation of antioxidants in treatment of chronic obstructive pulmonary disease.

From: http://www.sciencedirect.com/science/article/pii/S2213231713000645

Abstract

Neurons rely on the release and subsequent cleavage of GSH to cysteinylglycine (CysGly) by astrocytes in order to maintain optimal intracellular GSH levels. In neurodegenerative diseases characterised by oxidative stress, neurons need an optimal GSH supply to defend themselves against free radicals released from activated microglia and astroglia. The rate of GSH synthesis is controlled largely by the activity of γ-glutamyl cysteine ligase. Expression of γ-glutamyl cysteine ligase and of the Xc- system, which facilitates cystine uptake, is regulated by the redox-sensitive transcription factor, nuclear factor erythroid-2-related factor 2 (Nrf2). Compounds that can activate the Nrf2-ARE pathway, referred to as ‘Nrf2 activators’ are receiving growing attention due to their potential as GSH-boosting drugs.

This study compares four known Nrf2 activators, R-α-Lipoic acid (LA), tert-butylhydroquinone (TBHQ), sulforaphane (SFN) and Polygonum cuspidatum extract containing 50% resveratrol (PC-Res) for their effects on astroglial release of GSH and CysGly. GSH levels increased dose-dependently in response to all four drugs. Sulforaphane produced the most potent effect, increasing GSH by up to 2.4-fold. PC-Res increased GSH up to 1.6-fold, followed by TBHQ (1.5-fold) and LA (1.4-fold). GSH is processed by the ectoenzyme, γ-glutamyl transpeptidase, to form CysGly. Once again, SFN produced the most potent effect, increasing CysGly by up to 1.7-fold, compared to control cells. TBHQ and PC-Res both induced fold increases of 1.3, followed by LA with a fold increase of 1.2. The results from the present study showed that sulforaphane, followed by lipoic acid, resveratrol and Polygonum multiflorum were all identified as potent “GSH and Cys-Gly boosters”.

Resveratrol Upregulates Nrf2 Expression To Attenuate Methylglyoxal-Induced Insulin Resistance in Hep G2 Cells

From: http://pubs.acs.org/doi/abs/10.1021/jf302831d

Abstract

Oxidative stress can result in insulin resistance, a primary cause of type-2 diabetes. Methylglyoxal (MG), a highly reactive dicarbonyl metabolite generated during glucose metabolism, has also been confirmed to cause pancreatic injury and induce inflammation, thereby resulting in insulin resistance. Recently, resveratrol has been reported to exert antioxidant properties, protecting cells from the generation of reactive oxygen species (ROS). The aim of this study was to evaluate resveratrol activation of nuclear factor erythroid 2-related factor 2 (Nrf2) to attenuate MG-induced insulin resistance in Hep G2 cells. Therefore, the molecular signaling events affecting resveratrol-mediated heme oxygenase-1 (HO-1) and glyoxalase expression levels were further investigated in this study. Our findings indicated that resveratrol activated the extracellular signal-regulated kinase (ERK) pathway but not the p38 or c-Jun N-terminal kinase (JNK) pathways, subsequently leading to Nrf2 nuclear translocation and elevation of HO-1 and glyoxalase expression levels. Moreover, resveratrol significantly elevated glucose uptake and protected against MG-induced insulin resistance in Hep G2 cells. In contrast, depletion of Nrf2 by small interfering RNA (si-RNA) resulted in the abrogation of HO-1 and glyoxalase expression in the MG-treated resveratrol group in Hep G2 cells. Administration of an appropriate chemopreventive agent, such as resveratrol, may be an alternative strategy for protecting against MG-induced diabetes.

 

Resveratrol restores sirtuin 1 (SIRT1) activity and pyruvate dehydrogenase kinase 1 (PDK1) expression after hemorrhagic injury in a rat model.

From: http://www.ncbi.nlm.nih.gov/pubmed/24395567

 Abstract

Severe hemorrhage leads to decreased blood flow to tissues resulting in decreased oxygen and nutrient availability affecting mitochondrial function. A mitoscriptome profiling study demonstrated alteration in several genes related to mitochondria, consistent with the mitochondrial functional decline observed after trauma hemorrhage (T-H). Our experiments led to the identification of sirtuin 1 (SIRT1) as a potential target in T-H. Administration of resveratrol (a naturally occurring polyphenol and activator of SIRT1) after T-H improved left ventricular function and tissue ATP levels. Our hypothesis was that mitochondrial function after T-H depends on SIRT1 activity. In this study, we evaluated the activity of SIRT1, a mitochondrial functional modulator, and the mitochondrial-glycolytic balance after T-H. We determined the changes in protein levels of pyruvate dehydrogenase kinase (PDK)-1 and nuclear c-Myc, peroxisome proliferator-activated receptor-γ coactivator (PGC)-1α and NF-E2-related factor (NRF)2 after T-H and after treatment with resveratrol or a combination of sirtinol (a SIRT1 inhibitor) and resveratrol. We have also tested the activity of mitochondrial complex 1. SIRT1 enzyme activity was significantly decreased after T-H, whereas resveratrol treatment restored the activity. We found elevated PDK1 and c-Myc levels and decreased PGC-1α, NRF2 and mitochondrial complex I activity after T-H. The reduced SIRT1 activity after T-H may be related to declining mitochondrial function, since resveratrol was able to reinstate SIRT1 activity and mitochondrial function. The elevated level of PDK1 (an inhibitor of pyruvate dehydrogenase complex) after T-H indicates a possible shift in cellular energetics from mitochondria to glycolysis. In conclusion, SIRT1 modulation alters left ventricular function after T-H through regulation of cellular energetics.

 

Resveratrol suppresses PAI-1 gene expression in a human in vitro model of inflamed adipose tissue.

From: http://www.ncbi.nlm.nih.gov/pubmed/23819014

 Abstract

Increased plasminogen activator inhibitor-1 (PAI-1) levels are associated with a number of pathophysiological complications; among them is obesity. Resveratrol was proposed to improve obesity-related health problems, but the effect of resveratrol on PAI-1 gene expression in obesity is not completely understood. In this study, we used SGBS adipocytes and a model of human adipose tissue inflammation to examine the effects of resveratrol on the production of PAI-1. Treatment of SGBS adipocytes with resveratrol reduced PAI-1 mRNA and protein in a time- and concentration-dependent manner. Further experiments showed that obesity-associated inflammatory conditions lead to the upregulation of PAI-1 gene expression which was antagonized by resveratrol. Although signaling via PI3K, Sirt1, AMPK, ROS, and Nrf2 appeared to play a significant role in the modulation of PAI-1 gene expression under noninflammatory conditions, those signaling components were not involved in mediating the resveratrol effects on PAI-1 production under inflammatory conditions. Instead, we demonstrate that the resveratrol effects on PAI-1 induction under inflammatory conditions were mediated via inhibition of the NF κ B pathway. Together, resveratrol can act as NF κ B inhibitor in adipocytes and thus the subsequently reduced PAI-1 expression in inflamed adipose tissue might provide a new insight towards novel treatment options of obesity.

 

Effects of resveratrol in experimental and clinical non-alcoholic fatty liver disease.

From: http://www.ncbi.nlm.nih.gov/pubmed/24799987

 Abstract

The prevalence of obesity and related conditions like non-alcoholic fatty liver disease (NAFLD) is increasing worldwide and therapeutic options are limited. Alternative treatment options are therefore intensively sought after. An interesting candidate is the natural polyphenol resveratrol (RSV) that activates adenosinmonophosphate-activated protein kinase (AMPK) and silent information regulation-2 homolog 1 (SIRT1). In addition, RSV has known anti-oxidant and anti-inflammatory effects. Here, we review the current evidence for RSV-mediated effects on NAFLD and address the different aspects of NAFLD and non-alcoholic steatohepatitis (NASH) pathogenesis with respect to free fatty acid (FFA) flux from adipose tissue, hepatic de novo lipogenesis, inadequate FFA β-oxidation and additional intra- and extrahepatic inflammatory and oxidant hits. We review the in vivo evidence from animal studies and clinical trials. The abundance of animal studies reports a decrease in hepatic triglyceride accumulation, liver weight and a general improvement in histological fatty liver changes, along with a reduction in circulating insulin, glucose and lipid levels. Some studies document AMPK or SIRT1 activation, and modulation of relevant markers of hepatic lipogenesis, inflammation and oxidation status. However, AMPK/SIRT1-independent actions are also likely. Clinical trials are scarce and have primarily been performed with a focus on overweight/obese participants without a focus on NAFLD/NASH and histological liver changes. Future clinical studies with appropriate design are needed to clarify the true impact of RSV treatment in NAFLD/NASH patients.

 

Modulatory role of resveratrol on cytotoxic activity of cisplatin, sensitization and modification of cisplatin resistance in colorectal cancer cells.

From: http://www.ncbi.nlm.nih.gov/pubmed/25815689

 Abstract

Colorectal cancer (CRC) is a leading cause of cancer-associated mortality worldwide. Cisplatin (CIS) is one of the most active cytotoxic agents in current use and it has proven efficacy against various human malignancies. However, its clinical usefulness has been restricted by detrimental side effects, including nephrotoxicity and myelosuppression. The aim of the present study was to attempt to decrease the required dose of CIS, in order to minimize its side effects, and increase its capability to arrest, delay or reverse carcinogenesis. In addition, the present study aimed to ameliorate CIS‑resistance in CRC cells, using the natural compound resveratrol (RSVL). RSVL (3,4′, 5‑trihydroxy‑trans‑stilbene) is a naturally occurring polyphenol present in the roots of white hellebore (Veratrum grandiflorum O. Loes) and extracted from >70 other plant species. RSVL can exert antioxidant and anti‑inflammatory activities, and it has been shown to be active in the regulation of numerous cellular events associated with carcinogenesis. The present study evaluated the effects of RSVL on sensitization of both parent and CIS‑resistant HCT‑116 CRC cells to the action of cisplatin. The CIS was administered at a dose of 5 and 20 µg/ml, and CIS cytotoxicity, apoptosis, cell cycle and cisplatin cellular uptake were examined in the presence and absence of RSVL (15 µg/ml). RSVL treatment showed anti‑proliferative effects and enhanced the cytotoxic effects of cis against the growth of both parent and CIS‑resistant HCT‑116 CRC cells, with a half maximal inhibitory concentration of 4.20 µg/ml and 4.72 µg/ml respectively. RSVL also induced a significant increase in the early apoptosis fraction and enhanced the subsequent apoptotic effects of CIS. The cellular uptake of CIS was significantly increased in the presence of RSVL, as compared with CIS treatment alone, and RSVL treatment sensitized the CIS‑resistant HCT‑116 cells. In conclusion, RSVL treatment increased the cytotoxic activity of CIS against the growth of both parent and CIS‑resistant HCT-116 CRC cells.

 

Resveratrol treatment rescues hyperleptinemia and improves hypothalamic leptin signaling programmed by maternal high-fat diet in rats.

From: http://www.ncbi.nlm.nih.gov/pubmed/25801629

 Abstract

PURPOSE: Perinatal high-fat diet is associated with obesity and metabolic diseases in adult offspring. Resveratrol has been shown to exert antioxidant and anti-obesity actions. However, the effects of resveratrol on leptinemia and leptin signaling are still unknown as well as whether resveratrol treatment can improve metabolic outcomes programmed by maternal high-fat diet. We hypothesize that resveratrol treatment in male rats programmed by high-fat diet would decrease body weight and food intake, and leptinemia with changes in central leptin signaling.

METHODS: Female Wistar rats were divided into two groups: control group (C), which received a standard diet containing 9 % of the calories as fat, and high-fat group (HF), which received a diet containing 28 % of the calories as fat. Dams were fed in C or HF diet during 8 weeks before mating and throughout gestation and lactation. C and HF male offspring received standard diet throughout life. From 150 until 180 days of age, offspring received resveratrol (30 mg/Kg body weight/day) or vehicle (carboxymethylcellulose).

RESULTS: HF offspring had increased body weight, hyperphagia and increased subcutaneous and visceral fat mass compared to controls, and resveratrol treatment decreased adiposity. HF offspring had increased leptinemia as well as increased SOCS3 in the arcuate nucleus of the hypothalamus, which suggest central leptin resistance. Resveratrol treatment rescued leptinemia and increased p-STAT3 content in the hypothalamus with no changes in SOCS3, suggesting improvement in leptin signaling.

CONCLUSIONS: Collectively, our data suggest that resveratrol could reverse hyperleptinemia and improve central leptin action in adult offspring from HF mothers attenuating obesity.
