Project description:Reprogramming of ovarian aging epigenome by resveratrol

Project description:Depletion of oocytes and follicles and reduced oocyte quality contribute to age-associated ovarian senescence and infertility. Telomere shortening and altered methylation make two major contributions to general aging. Resveratrol acts as anti-oxidant and Sirt1 activator to alleviate aging including reproductive aging. It remains elusive whether resveratrol can reprogram the aging epigenome. We sought to examine aging ovarian epigenome and the potential effects of resveratrol by combined analysis of telomere length, transcriptome and methylome mainly in oocytes and also in granulosa cells, two major cell types in the ovary.

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.

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.

Project description:Ovarian aging is characterized by the progressive depletion of primordial follicle reserve, leading to irregular patterns of ovulation and menopause. The basic mechanisms that underlie the ovarian aging and follicle decline is unknown. We sought to explore the role of cellular senescence and epigenomic mechanisms in ovarian aging. Here, we present the transcriptomic changes observed in the ovaries with age using the age groups 3mo, 6mo, 9mo and 12mo (n=5 per group except for 12mo which has an n=4). The age groups capture timepoints from sexual maturation to reproductive health decline.

Project description:The gene expression profiling analyses by DNA chip showed that the gene expression pattern of mice fed resveratrol-enriched rice DJ526 was very different from mice fed either resveratrol or Dongjin rice alone, respectively, modifying expression of genes related to aging regulation, cell differentiation, extracellular matrix, neurogenesis, or secretion.
