The Story of Vitamin C in Expression of Breast Cancer

By Kyle J. Norton


Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin, found in fresh fruits, berries and green vegetables. It is best known for its free radical scavengers activity and regenerating oxidized vitamin E for immune support.

Epidemiological studies linking vitamin C in reduced risk of breast cancer may be inconclusive(1)(1a)(1b), but no doubt in acceptance of improved quality of life(2).

Macro nutrients intake may form an important parts in breast cancer patients in providing vital support for treatment.(3). There was a report of intake of supplementation of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer(3a). 

Women with breast cancer in the Indian population, were found to have a lower levels of mean vitamin C, vitamin E and selenium than controls. if the levels of mean vitamin C, vitamin E and selenium increased by 1 unit, the risk of breast cancer was reduced by 7%(3b).

In breast cancer survival, dietary vitamin C intake before breast cancerdiagnosis may be associated with breast cancer survival. but not in post-diagnosis(4). 

High intake of ascorbic acid was in associated to reduce risk of breast cancer incidence in overweight women and women with high consumption of linoleic acid (average consumption of more than 6 grams of linoleic acid per day)(5) and insignificant risk in other breast cancer patients(6). 

On inflammation in cancer patients, high dose intravenous ascorbic acid therapy, decreased the levels of C-reactive protein thus reduced inflammation correlated with decreases in tumor marker levels(7). 

Vitamin C supplements and Anthocyanin (Ixor®) at a dose of 2 tablets/day, starting from 10 days before the radiation treatment until 10 days after the end of treatment was found to be protective against skin damage to patient undergoing adjuvant chemotherapy(8).

In estrogen-induced breast carcinogenesis, vitamin C (Vit C) and butylated hydroxyanisole (BHA) found to be effective in inhibition of 17β-estradiol (E2)-mediated oxidative stress and oxidative DNA damage by preventing the decreasing NRF2(antioxidant response pathway) and OGG1(base excision repair.) levels(9). 

In the study of the same but in MCF-10A cells, the combination also decreased E2-mediated increase in 8-OHdG(Marker detected in cancer patients) levels in the mammary tissues, induced SOD3 (Extracellular superoxide dismutase [Cu-Zn]) through NRF2 Pathway to defense against oxidative stress and in the prevention of estrogen-mediated breast cancer(10).

An increased expression of the miR-93(Regulate Expression of Tumor Suppressor Gene) was found in 17β-estradiol (E2)-treated mammary tissues and in human breast cell lines, treatment with vitamin C reverted E2-mediated increase in miR-93 levels by upregulating expression NRF2 antioxidant response pathway(11). 

In 4T1 breast cancer cells in vitamin C-deficient mice, Ascorbic acid delayed the progress of metastasis, tumor growth and inflammatory cytokine secretion (decreased serum inflammatory cytokine interleukin (IL)-6) as well as enhanced encapsulation of tumors(12).

 In L-ascorbate (L-ascorbic acid, vitamin C), increasing the concentration exhibited the autophagic damage to functional SVCT-2(antibody) sensitizes breast cancer cells(13). 

In B16F10, L-ascorbate also caused induction of a prooxidant state, subsequent reduction in mitochondrial membrane potential to induced apoptosis in a caspase-8(Cell apoptosis)-independent manner(14).

 In the usage of glucan, resveratrol and vitamin C, the combination showed the strongest activator of phagocytosis (immune cell activation) and antibody formation to suppress the growth of breast and lung tumors, through stimulation of apoptosis(15). 

In 4T1 cancer cell line, combined with ascorbate, Mn(III)N-alkylpyridylporphyrins (MnPs) inhibited cancer cells via peroxide produced outside of the cell through enhancing tumour oxidative stress and tumor growth suppression(16). 

In Ataxia telangiectasia mutated (ATM) diplotype on the breast cancer, vitamin C enhanced the increase of ATM to reduce the risk of breast cancer.(17). 

In E(2) metabolism and oxidant stress in involved in estrogen-induced breast cancer development, vitamin C reducesd the incidence of estrogen-induced mammary tumors, increased tumor latency and decreases oxidative stress in vivo(18). 

In SK-BR3 and Hs578T breast cancer cell lines, Vitamin C treatment induced AIF(apoptosis-inducing factor) mediation of cell death pathway of the breast cancer cell lines independent to caspase pathway(19).

In human breast cancer cell line MCF-7, combination of Retinoic acid and ascorbic acid inhibited the proliferation of human breast cancercells through altering their gene expression related to antioxidation processes and the proliferation inhibitory pathway(20).

Taking all together, without going into reviews, vitamin C is effective in reduced risk and  treatment of breast cancer. 

Daily ingestion of high-dose vitamin C may be considered safe, but in rare incidence, overdoses in a prolonged period of time, may cause intra-renal oxalate crystal deposition, a fatal nephrotoxicity(21)(22).

Warning to: Fish Omega 3 Supplement Consumers, Beware of 14 Side Effects

Kyle J. Norton

Omega-3 fatty acids are phytochemincals in the class of lipids, found abundantly in deep sea fish, dark-green leafy vegetables, grains, legumes, nuts,.....

Fish oil omega-3 fatty acids, contained mainly eicosapentaenoic acid and docosahexaenoic acid, although the supplement has been found to process some significant effects in the management and treatment of several diseases, many of which are inflammatory in nature. However, the supplement may induce some outlined adverse effects.




1. Altered platelet function Omage 3 fatty acid made from fish may have a strong implication on plaletet function due to the presence of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in increased occlusion time and sharply reduced accumulation of fibrin under flow conditions(1)(2).
Therefore, people with normal bleeding problem should be avoid taking the supplement(2).

2. Gastrointestinal adverse effects
Although Omega-3 fatty acids may have a potential in triglycerides lowering, reduction of inflammatory indices, immunomodulation, anti- thrombotic effects, particularly in gastro-protective activity. However, when the healthy supplement taken together with cortisone may cause gastrointestinal bleeding in induction of duodenum ulcer.

This result may be attributed by cortisone in increased oxidation in render them proinflammatory(3).



Other researchers suggested that over doses of omega-3 fatty acids may enhance intestinal production and secretion of intestinal alkaline phosphatase (IAP), in induction of the induces changes of gut bacteria composition resulting in decreased lipopolysaccharide production and gut permeability(7).




3. Detrimental Effects on Wound Healing
In the observation of epidermal growth factor receptor (EGFR)-mediated signaling is required for optimal intestinal wound healing, researchers found that during the early response to intestinal wounding, DHA and EPA uniquely delay the activation of key wound-healing processes in the colon through at least in part suppression of EGFR function(4).

4. Increased risk of lipid peroxidation
Omega 3 fatty acide may interact with reactive oxygen species ROS in inscreased risk of lipid peroxidation in induction of ethane expression in human breath(5).

5. Toxin exposure
Omega 3 fatty acid produced by large amounts of fish may result in adverse effect due to the potential presence of environmental toxins such as mercury, polychlorinated biphenyls, dioxins,.... (8).

Moreover, omega-3 fatty acid preparation may undergo oxidation incontribution to patient intolerance and potential toxicity(8).


6, Weight gain
Intake of omega 3 fatty during pregancy may have a potential effect in induced weight gain of male offspring a poor outcomes associated with high maternal weight gain early in pregnancy(10)..


7. Altered immune function
Omega 3 fatty acide with abubdant arachidonic acid, EPA and DHA contents may alter the balanced pattern of production of eicosanoids and probably also of docosanoids and resolvins, affecting phagocytosis, T-cell signaling and antigen presentation capability.(11).

8. Glycemic control
According to a randomized double-blind crossover study in compared 6 wk of n-3 fatty acid supplementation (12 g fish oil) and corn plus olive oil, long term intake of 3 fatty acid supplementation expressed in increased glycerol gluconeogenesis in contribution to deterioration of glycemic control(12).

However, during the 6 weeks of experiment, researchers also found intake of n-3 fatty acid supplementation lowers triacylglycerols in patients with non-insulin-dependent diabetes mellitus without worsening glycemic control(12).

Drug interactions
Intake of Omega-3 fatty acids
9. May increase the effects of blood thinning medications, including aspirin, warfarin (Coumadin), and clopedigrel due to its anti coagulative activity(13).

10. May increase fasting blood sugar levels, thus reducing the effect of blood sugar lowering medications, such as ,glipizide (Glucotrol and Glucotrol XL), glyburide (Micronase or Diabeta), glucophage (Metformin)(13).

11. Lower the effect of Cholesterol-lowering medications due to the alternation of ratio of good and bad cholesterol(13).



12. Pregnancy and 13. Lactation
Consumption of the nutrients omega-3 fatty acids (omega-3 FA) during pregnancy and lactation is considered beneficial to fetal and infant development. However, according to the animal study by the Wayne State University School of Medicine, Consuming or administering large or inadequate amounts of omega-3 FA during pregnancy and lactation may induce the potential for adverse effects on infant development(6).

14. Impair host resistance to intracellular pathogens
In the study of Wild-type and fat-1 transgenic mice infected with virulent H37Rv M. tuberculosis via the aerosol route, observartion of bacteriological and histopathological changes in lungs, researchers suggested that endogenous production of n-3 PUFAs in fat-1 mice increases their susceptibility to tuberculosis due to impaired bacterial control in cells and reduced proinflammatory cytokine secretion, impaired oxidative metabolism, and diminished M. tuberculosis-lysotracker colocalization within phagosomes(9).

Food Therapy: Intake Fennel to Optimize the Digestive Functioning in absorbed Nutrients and Fluids

Kyle J. Norton

Fennel may have a therapeutic and enhanced effect in improve digestive system in absorbed nutrients and fluids from foods intake, some scientists suggested.

The result of this efficacy was published online by several respectable institutes, including the University of Illinois at Chicago and Afyon Kocatepe University.

Fennel (Foeniculum vulgare) is a plant species of genus, belongings to Apiaceae (Umbelliferae), native to the Mediterranean, used in traditional and herbal medicine as warming, carminative, antispasmodic, antidepressant agent and to stimulate the appetite, ease indigestion, soothe coughing, reduce intestinal spasms, to regulate the menstrual cycle and relieve PMS,...

Nutrients
1. Carbohydrates
2. Fiber
3. Protein
4. Thiamine (Vitamin B1)
5. Riboflavin (Vitamin B2)
6. Niacin (Vitamin B3)
7. Pantothenic acid (B5)
8. Vitamin B6
9. Folate (Vitamin B9)
10. Vitamin C
11. Calcium
12. Copper
13. Iron
14. Magnesium
15. Molybdenum
16. Phosphorus
17. Potassium
18. Zinc
19. Etc.


According to the study, researchers set out a criteria and guideline to investigate the effect of fennel in gram-negative bacterium Helicobacter pylori (HP), the microorganisms has been associated with the development of gastritis and peptic ulcer disease to confirm the theory of used in traditional medicine fennel to treat a wide range of ailments, including gastrointestinal (GI) disorders such as dyspepsia, gastritis and peptic ulcer disease (PUD), application of methanol extracts of botanicals with a MIC of 50 microg/mL included Achillea millefolium, Foeniculum vulgare (seed), exerted a significantly inhibitory effect against all susceptibility of 15 HP strains.

These results suggested that injection of fennel displayed a potential in balanced the ratio of micro organisms in the gastrointestinal tract, thus improve the function in absorbed and distributed nutrients to the body and reassured the herbal medicine used in practice for treatment of numbers symptoms of 
digestive disorder.

Furthermore, in animal model with rat induced gastric lesions by injection of ethanol, application of aqueous extracts of Foeniculum vulgare (FVE) showed a strong activity in inhibited the ulcerogenic expression through its antioxidant activities..

In observation of the efficacy of 60 minutes pre administration of the doses of 75, 150 and 300 mg/kg, with famotidine, histamine H₂ receptor antagonist with function to inhibit stomach acid production, used at the dose of 20 mg/kg, before injection of ethanol, researchers found that
* Pre treatment of all dose exerted a significant gastric protective effect in reduced injure and damage caused by injection of ethanol.

* Fennel extract demonstrated a theurateutic activity linearly in compared to other doses and control at dose of 300 mg/kg 

* These activities was associated to reduce the malondialdehyde (MDA) levels, a marker in expression of severe levels of oxiadive stress.

Additional analysis, also suggested that fennel stimulated gastro-protect effect through its antioxidants and facilitated production of antioxidants found in the body tissues in inhibited the over expression of free radicals, Thus maintaining the ratio of micro organisms in the digestive tract and its functioning.

After, taking into account of other co and con founders, researchers also suggested that the result in part may also attributed to antioxidant in ameliorated lipid peroxidation.

The above differentiation were supported by the joint report lead by the Joint Keio University in the investigation of fennel properties in associated to functional dyspepsia (FD), a functional gastrointestinal disorder characterized by persistent or recurrent postprandial upper abdominal discomfort and epigastric pain.

Truly, Delayed gastric emptying and impaired gastric accommodation was found to play important roles in the development of FD. 

Anethole (1-methoxy-4-((E)-propenyl)-benzene), a major component of fennel essential oil, in in rodents exerted a huge effect in improved clonidine-induced delayed gastric emptying without harming to normal gastric emptying in mice, orally.

Also, application of fennel oil plus Anchu-san (a Japanese herbal medicine containing anethole) also demonstrated a important activity in reduced risk of functional dyspepsia (FD) through restoring the delayed gastric emptying.

In other words,  anethole processes a gastro protective efficacy through stimulating gastric accommodation. 

Taken together, whole fennel, fennel essential oil and its bioactive compound anethole may be used as secondary application in reduced risk and treatment of digestive disorder. Adding a portion of fennel in your diet may improve the digestive function in absorption nutrients and fluids from the food intake.

However, intake of supplement should be taken with extreme care as overdose may cause acute liver toxicity.

How to Improve Your Brain Functioning Effectively

By Kyle J. Norton

Scientists may have found a food whole plant in exerting neuroprotective effect, the renowned institute study suggested.

According to the MVP Samaj’s College of Pharmacy, methinic extract of beet fed to experiment animal showed a significant effect in increased motor function at 200, and 300 mg/kg, in doses depending manner.

Neuroprotection is an action used to ensure the brain normal function against nerve cells damage, degeneration in inducing impairment.

Beet, best known as the beetroot or garden beet and belonging to the amaranth family, is a perennial plant with leafy stems growing to 1–2 m tall.

According to the MVP Samaj’s College of Pharmacy, methinic extract of beet fed to experiment animal showed a significant effect in increased motor function at 200, and 300 mg/kg, in doses depending manner.


Oral administrated animal also showed a strong improvement of intensity of muscular rigidity, duration of catalepsy, akinesia, the number of tremors, locomotor activity and grip strength.


The efficacy of the extracted in contribution of brain health may be a result of present phytochemicals in restoring the defensive antioxidant enzymes in the brain against level of lipid peroxidation (LPO), a leading cause of neuro degeneration.

More interestingly, Betalains, major phytochemicals isolated from beetroot also expressed a extraordinary neuro protective effect in preventing oxidative processes in contribution to the early onset of several degenerative diseases.

In the study of betanin bioavailability in four volunteers with consumption 300 mL of red beet juice, containing 120 mg of the antioxidant, reseraches found that the phytochemical showed a protection against certain oxidative stress-related disorders in humans after absorbed from the gut and identified in urine after 2-4 h, particularly in inhibited lipid peroxidation, a leading cause of neuro degenerative disease.

Dr. Kanner J, the lead author said, “Antioxidant nutrients from fruits and vegetables are believed to be a class of compounds that exert their effects in humans by preventing oxidative processes which contribute to the onset of several degenerative diseases”.



Collectively, Whole food beetroot or beet juice may be used as therapeutic agent for preventing the early onset and treatment of neuro degenerative disease through protection of neuro cells against oxidation.

Diabetics Attention: How to Reduce Your Blood Glucose Levels, Medical Literature Suggested


Kyle J. Norton

For my years of practice and research, I do believe that intake of 1/4 table spoon of Vietnmese cinnamon powder in the morning and evening have significant effects to keep blood sugar in check.

Prediabetes with reading of 6.9 mmol/L of a lady I know 10 years ago, after taking the suggested amount daily, reading of the morning blood plucose is maintained at 5.3 mmol/L since.

Cinnamon, a kitchen spicy in many cultures, may have gained many believers, including medical professions because of its anti diabetic effect, through regulating the blood glucose levels in healthy and diabetic subjects.


According to herbalists, intake of 1/4 tsp. in the morning and evening may reduce the blood sugar significantly with little or no adverse side effects.

The herb has been use in herbal and traditional medicine as anti-fungal and bacteria level to improve reproductive organ, prevent flatulence and intestinal cramping, treat indigestion, diarrhea, bad breath, headache, migraine, etc.(1).


According to the 2011 statistic from National Diabetes InformationClearinghouse (NDIC), among U.S. residents ages 65 years and older, 10.9 million, or 26.9 percent, had diabetes in 2010, about 215,000 people younger than 20 years had diabetes—type 1 or type 2—in the United States in 2010 and approximately, 1.9 million people ages 20 years or older were newly diagnosed with diabetes in 2010 in the United States.

In a total of 66 patients with type 2 diabetes study conducted by Xuhui District Central Hospital, showed a reduction significant of blood triglyceride levels even in the low-dose group, after 3 months of oral administration(2)

Some researchers suggested that cinnamon extract improved fasting blood glucose levels and glucose tolerance without altering the insulin secretion, through lower triglyceride and increased liver glycogen content and improved insulin action in liver tissues(3).

Dr. Kim SH and Dr. Choung SY. told PubMed that “the effect of cinnamon in significantly increases insulin sensitivity, reduces serum, and hepatic lipids, and improves hyperglycemia and hyperlipidemia possibly by regulating the PPAR-medicated glucose and lipid metabolism”(4)

In support of the above, chromium(Cr) and polyphenols found in cinnamon(Cinnamomon cassia) indicated a improvement of glucose, insulin, cholesterol and HbA1c in patients with type 2 diabetes following Cr supplementation, in a double-blind placebo-controlled study(7).

Unfortunately, according to the Western University of Health Sciences, consumption of cinnamon is associated with a statistically significant decrease in levels of fasting plasma glucose, but insisted that high degree of heterogeneity may limit the ability to apply these results to patient care, due to the unclear preferred dose and duration of therapy(5)

A randomized clinical trial in which 70 Patients with type II diabetesassigned randomly two groups (35 in cinnamon and 35 in placebo group for the testing of the effect of cinnamon on the glucose level in blood, indicated an insignificant effect of using cinnamon on glucose level of diabetic patients and the herb should not be recommended to patients with type II diabetes depending on further studies(6).

Taken altogether, cinnamon in low dose may be effective in controlling the levels of blood glucose in patient with diabetes without altering the insulin level. according to DR. Georgakopoulou EA(7), Oral intake of Cinnamon may cause Stomatitis, and burning sensation in mouth with large amount. The traditional Chinese medicine also insisted that Overdoses of cinnamon can be toxic and damaged to liver(1).

Grape is a woody vines of the genus Vitis, belong to the family Vitaceae, native to southern Turkey.

Grape Seed Extract is the commercial extracts from whole grape seeds, containing many concentrations, including vitamin E, flavonoids, linoleic acid, oligomeric proanthocyanidins(OPCs),...

The herb has been used in traditional medicine as antioxidant, anti-inflammatory agents and to treat skin wounds with less scarring, allergies, macular degeneration, arthritis, enhance circulation of blood vessels, lower cholesterol, etc.

 Resveratrol is a phytochemical in the class of Stilbenoids, found abundantly in skins and seed of grape wine, nuts, peanuts,....


1. Anti cancers
In the review of resveratrol and it effects as a chemopreventive agent, tumor initation, promotion, and progression via multiple pathways, indicated that resveratrol exerts antioxidant activities, hence contributing to the prevention of tumor initiation. Growing or metastasizing carcinomas are inhibited by resveratrol through prevention of angiogenesis by inhibiting VEGF and matrix metalloproteases. Induction of apoptosis and cell cycle arrest, important mechanisms for cancer therapy, are stimulated by resveratrol through different mechanisms, e.g., activation of p53 and modulation of cell cycle proteins, according to "Fighting cancer with red wine? Molecular mechanisms of resveratrol" by Kraft TE, Parisotto D, Schempp C, Efferth T.(1)

2. Anti cancers and anti inflammatory effects
In the observation of Resveratrol's effects in exhibition of several physiological activities including anticancer and anti-inflammatory activities in vitro and in experimental animal models, as well as in humans, found that Anticancer activity of this compound is mainly due to induction of apoptosis via several pathways, as well as alteration of gene expressions, all leading to a decrease in tumor initiation, promotion, and progression. Resveratrol exhibits anti-inflammatory activity through modulation of enzymes and pathways that produce mediators of inflammation and also induction of programmed cell death in activated immune cells. Resveratrolhas been shown to produce no adverse effects, even when consumed at high concentrations, according to "Potential of resveratrol in anticancer and anti-inflammatory therapy" by Udenigwe CC, Ramprasath VR, Aluko RE, Jones PJ.(2)

3. Prostate cancer
In the evaluation of the tumor suppressor gene PTEN (phosphatase and tensin homolog deleted on chromosome 10) and the androgen receptor (AR) in tumor development and progression in prostate carcinogenesis, found that resveratrol may act as potential adjunctive treatment for late-stage hormone refractory prostate cancer. More importantly, for the first time, our study demonstrates the mechanism by which AR regulates PTEN expression at the transcription level, indicating the direct link between a nuclear receptor and the PI3K/AKT pathway, according to "Resveratrol regulates the PTEN/AKT pathway through androgen receptor-dependent and -independent mechanisms in prostate cancer cell lines' by Wang Y, Romigh T, He X, Orloff MS, Silverman RH, Heston WD, Eng C.(3)

4. Cardiovascular diseases
In the revie of reviews some of the key studies, and the known mechanisms for these beneficial effects. Evidence from different experimental studies, including from the authors' laboratories, and the beneficial effects of polyphenols found in red wine, especially resveratrol in grape skins.
found that Resveratrol benefits include a reduction in cardiovascularmorbidity and mortality, lung cancer and prostate cancer by approximately 30% to 50%, 57% and 50%, respectively. Polyphenols possess antioxidant, superoxide-scavenging, ischemic-preconditioning and angiogenic properties. Some of these properties of polyphenols may explain their protective effects on the cardiovascular system, as well as other body organs, according to "Significance of wine and resveratrol in cardiovascular disease: French paradox revisited" by Vidavalur R, Otani H, Singal PK, Maulik N.(4)

5. Cardiovascular health
In the review of Resveratrol (3,4',5-trihydroxystilbene), a member of natural, plant-derived chemicals known as polyphenols and is attracting increased attention due to its diverse health benefits especially in case of cardiovascular disease, cancer, diabetes and neurological problems, indicated that Recently, resveratrol was found to induce autophagy and regenerate myocardial ischemic tissue treated with stem cells. Overall observation indicates that resveratrol has a high therapeutic potentials for the treatment of cardiovascular diseases, according to "Resveratrol and cardiovascular health" by Das M, Das DK.(5)

6. Anti inflammatory effects
In the study of implantation and growth of metastatic cancer cells at distant organs is promoted by inflammation-dependent mechanism, found that resveratrol remarkably inhibited hepatic retention and metastatic growth of melanoma cells by 50% and 75%, respectively. The mechanism involved IL-18 blockade at three levels: First, resveratrol prevented IL-18 augmentation in the blood of melanoma cell-infiltrated livers. Second, resveratrol inhibited IL-18-dependent expression of VCAM-1 by tumor-activated hepatic sinusoidal endothelium, preventing melanoma cell adhesion to the microvasculature. Third, resveratrol inhibited adhesion- and proliferation-stimulating effects of IL-18 on metastatic melanoma cells through hydrogen peroxide-dependent nuclear factor-kappaB translocation blockade on these cells, according to "Resveratrol prevents inflammation-dependent hepatic melanoma metastasis by inhibiting the secretion and effects of interleukin-18" by Salado C, Olaso E, Gallot N, Valcarcel M, Egilegor E, Mendoza L, Vidal-Vanaclocha F.(6)

7. Oxidative stress and endothelial dysfunction
In the investiagtion of the role of S6K1 in aging-associated endothelial dysfunction and effects of the polyphenol resveratrol on S6K1 in aging endothelial cells, wrote that our data demonstrate a causal role of the hyperactive S6K1 in eNOS uncoupling leading to endothelial dysfunction and vascular aging. Resveratrol improves endothelial function in aging, at least in part, through inhibition of S6K1. Targeting S6K1 may thus represent a novel therapeutic approach for aging-associated vascular disease, according to "Hyperactive S6K1 mediates oxidative stress and endothelial dysfunction in aging: inhibition by resveratrol" by Rajapakse AG, Yepuri G, Carvas JM, Stein S, Matter CM, Scerri I, Ruffieux J, Montani JP, Ming XF, Yang Z.(7)

8. Insulin resistance
In the evaluation of the effects of Res on insulin sensitivity and the underlying mechanism, insulin-resistant KKA(y) mice were treated with 2 and 4 g/kg diets of Res for 12 weeks, found that Res intervention reduces blood glucose and serum insulin levels, improves insulin and glucose tolerance, increases serum adiponectin and adiponectin mRNA levels in epididymal adipose tissues, and more importantly, elevates Sirt1, p-AMPK, p-IRS1, and p-AKT levels in liver and soleus muscles, according to "Effects of resveratrol on the amelioration of insulin resistance in KKA(y) mice" by Chen S, Li J, Zhang Z, Li W, Sun Y, Zhang Q, Feng X, Zhu W.(8)

9. Propionibacterium acnes
In the investigation of whether P. acnes biofilms could be eradicated by plant extracts or their active compounds, and whether other mechanisms besides killing of biofilm cells could be involved, found that out of 119 plant in the study, researchers identified five with potent antibiofilm activity against P. acnes (extracts from Epimedium brevicornum, Malus pumila, Polygonum cuspidatum, Rhodiola crenulata and Dolichos lablab). We subsequently identified icariin, resveratrol and salidroside as active compounds in three of these extracts. Extracts from E. brevicornum and P. cuspidatum, as well as their active compounds (icariin and resveratrol, respectively) showed marked antibiofilm activity when used in subinhibitory concentrations, indicating that killing of microbial cells is not their only mode of action, accoridng to "Eradication of Propionibacterium acnes biofilms by plant extracts and putative identification of icariin, resveratrol and salidroside as active compounds" by Coenye T, Brackman G, Rigole P, De Witte E, Honraet K, Rossel B, Nelis HJ.(9)

10. Healthy heart and longevity
In the review focuses on the anti-aging aspects of resveratrol, the possible mechanisms of action,
found that resveratrol can induce the expression of several longevity genes including Sirt1, Sirt3, Sirt4, FoxO1, Foxo3a and PBEF and prevent aging-related decline in cardiovascular function including cholesterol level and inflammatory response, but it is unable to affect actual survival or life span of mice, according to "Resveratrol and red wine, healthy heart and longevity" by Das DK, Mukherjee S, Ray D.(10)

11. Antioxidants
In the assessment of the effects of the antioxidants resveratrol and quercetin on frozen-thawed ram sperm, found that Semen samples (which exceeded minimum standards) from four mature crossbreed Santa Inês rams were pooled and aliquots of each pool were diluted in Tris-egg yolk-glycerol, with the addition of 0, 5, 10, 15, and 20 μg/mL of resveratrol and quercetin in Experiment 1 and Experiment 2, respectively. In Experiment 1, the proportion of sperm with a high mitochondrial membrane potential was greater (P < 0.02) in the control group than in resveratrol 20 μg/mL group. In Experiment 2, the proportion of sperm with high mitochondrial membrane potential was greater in the control group (P < 0.0001) than in the other experimental groups, and greater in the quercetin 5 μg/mL group (P < 0.05) than in the other quercetin-treated groups, according to "Effect of antioxidants resveratrol and quercetin on in vitro evaluation of frozen ram sperm" by Silva EC, Cajueiro JF, Silva SV, Soares PC, Guerra MM.(11)

12. Incision-induced acute and chronic pain
In the searching for more efficacious treatments in inhibition of incision-induced pain and prevention of the transition to chronic pain following surgery, found that local injection of resveratrol around the surgical wound strongly attenuates incision-induced allodynia. Intraplantar IL-6 injection and plantar incision induces persistent nociceptive sensitization to PGE2 injection into the affected paw after the resolution of allodynia to the initial stimulus. We further show that resveratrol treatment at the time of IL-6 injection or plantar incision completely blocks the development of persistent nociceptive sensitization consistent with the blockade of a transition to a chronic pain state by resveratrol treatment, according to "Resveratrol engages AMPK to attenuate ERK and mTOR signaling in sensory neurons and inhibits incision-induced acute and chronic pain" by Tillu DV, Melemedjian OK, Asiedu MN, Qu N, De Felice M, Dussor G, Price TJ.(12)

13. Anti diabetes

In the evaluation of resveratrol, a polyphenolic SIRT1 activator and its SIRT1 activation in an in vitro fluorescent based assay (EC(50) : 7 μM) and the efficacy of resveratrol was also evaluated in ob/ob mice for its antidiabetic and associated metabolic effects, found that a significant improvement observed in the glucose excursion in the oral glucose tolerance test performed for 120 min; although an insignificant improvement in the triglycerides, total cholesterol, adiponectin and free fatty acid levels was observed at different doses of resveratrol tested. The present findings suggest that resveratrol is an antihyperglycemic agent and drugs similar to resveratrol can be considered as an effective therapeutic adjuvant for the current treatment of diabetes mellitus, according to "Antidiabetic activity of resveratrol, a known SIRT1 activator in a genetic model for type-2 diabetes" by Sharma S, Misra CS, Arumugam S, Roy S, Shah V, Davis JA, Shirumalla RK, Ray A.(13)

14. Neuroprotective effects
In the elucidation of the neuroprotective effect and influence of resveratrolon the extracellular levels of neurotransmitter and neuromodulator during ischemia/reperfusion in rats,
found that chronic treatment with resveratrol remarkably reduced the release of excitatory neurotransmitter glutamate, aspartate and neuromodulator d-Serine during ischemia and reperfusion; and significantly increased the basal extracellular levels of inhibitory neurotransmitter gamma-amino-n-butyric acid, glycine and taurine. Chronic treatment with resveratrol also ameliorated O-phosphoethanolamine levels and excitotoxic index during ischemia and reperfusio, according to "Neuroprotective effects of resveratrol on ischemic injury mediated by modulating the release of neurotransmitter and neuromodulator in rats" by Li C, Yan Z, Yang J, Chen H, Li H, Jiang Y, Zhang Z(14)

15. Neuroprotective effects
In the investigation of the neuroprotective properties of resveratrol found that Resveratrol has neuroprotective features both in vitro and in vivo in models of Alzheimer's disease (AD), but it has proved to be beneficial also in ischemic stroke, Parkinson's disease, Huntington's disease, and epilepsy, according to "Neuroprotective properties of resveratrol in different neurodegenerative disorders" by Albani D, Polito L, Signorini A, Forloni G.(15).
