Project description:Resveratrol is a natural product that has gained tremendous interest due to multiple reported health-beneficial effects. However, the underlying mechanisms of action of this compound remained largely controversial. Here, we demonstrate that major biological effects of resveratrol might be attributed to its bicarbonate-induced production of phenolic radicals and reactive oxygen species (ROS) such as superoxide and hydrogen peroxide under physiologically relevant conditions. These products derived from low hormetic micromolar concentrations of resveratrol led to gene expression reprogramming, which was mainly controlled by the redox-sensitive transcription factor nuclear factor (erythroid-derived 2) like 2 (Nrf2), whereas too high concentrations of resveratrol became detrimental for cells. Gentle but significant activation of Nrf2-controlled gene expression resulted in a metabolic switch and reduced cellular redox environment. Thereby cells could be preconditioned against stress, for example to protect primary keratinocytes of the human epidermis from oxidative stress that was induced by metabolization of ethanol. Hormetic shifting of cells by chemical triggers such as resveratrol towards a more reductive state might represent a powerful conceptual framework to improve cellular fitness at low nontoxic concentrations. Total RNA obtained from cultured primary neonatal normal human epidermal keratinocytes (NHEK) subjected to 16 hours treatment with 50 µM resveratrol (trans-3,5,4â-trihydroxystilbene, RSV) compared to vehicle-treated control NHEKs.

Project description:Expression profiling of LY6E-silent THP-1 cells (THP-1-shLY6E) and control cells (THP-1-shCtrl). Results provide evidence that LY6E is effectively knocked down in THP-1shLY6E, compared to THP-1-shCtrl, and show the different expressed genes following LY6E silence in THP-1 cells. Total RNA obtained from 2 cell lines.

Project description:Resveratrol, a natural phytoestrogen found in red wine and a variety of plants, is reported to have protective effects against lung cancer, however there is very little work directed towards the understanding of the mechanism of action of resveratrol in lung cancer. In this study we used an experimental approach to understand the biological activity and molecular mechanisms of resveratrol in A549 lung cancer cells. Gene expression profiles were compiled using an oligonucleotide microarray to determine altered expression levels in resveratrol treated cells. Keywords: Genetic modification of A549 cells in response to resveratrol

Project description:Resveratrol delays age-related deterioration and mimics transcriptional aspects of dietary restriction without extending lifespan A small molecule that safely mimics the ability of dietary restriction (DR) to delay age-related diseases in laboratory animals is greatly sought after. We and others have shown that resveratrol mimics effects of DR in lower organisms. In mice, we find that resveratrol induces gene expression patterns in multiple tissues that parallel those induced by DR and every-other-day feeding. Moreover, resveratrol-fed elderly mice shows a marked reduction in signs of aging including reduced albuminuria, decreased inflammation and apoptosis in the vascular endothelium, increased aortic elasticity, greater motor coordination, reduced cataract formation, and preserved bone mineral density. However, mice fed a standard diet did not live longer when treated with resveratrol beginning at mid-life. Our findings indicate that resveratrol treatment has a range of beneficial effects in mice but does not increase the longevity of ad libitum-fed animals when started mid-life. Male C57BL/6NIA mice at 11 months of age were maintained on a standard purified mouse diet (AIN-93G) for one month prior to the start of the experiment. Beginning at one year of age, SD and EOD groups were fed a standard AIN-93G diet or AIN-93G plus 0.01% or 0.04% resveratrol for the duration of the study. Three separate groups were placed on an HC diet (AIN-93G modified by the addition of hydrogenated coconut oil to provide 60% of calories from fat) or HC + 0.01% or 0.04% resveratrol 6 weeks later and remained on those diets throughout the study. SD and HC mice were fed ad libitum. EOD mice were fed ad libitum on alternate days then moved to a separate cage without food for 24 h. Food intake and body weight were measured on a weekly basis for the duration of the study.
