Metformin, aging and cancer
cancers are associated with aging [1]. Metformin, a widely used antidiabetic drug, has been linked to a reduced cancer incidence in some retrospective, hypothesis-generating studies [2]. Since cancer and aging may share certain molecular processes, it is plausible that metformin may prevent cancer by acting on the aging process. Consistent with this idea, several studies report a life span exte...
متن کاملAn Update on Ovarian Aging and Ovarian Reserve Tests
Ovaries are the female organs that age more quickly than other tissues such as the uterus, the pituitary gland or pancreas. Different from males, an interesting question is why and how the females lose fertility so rapidly. During the aging process, both the number and quality of the oocytes in the ovaries decrease and reach to a point beyond that no more viable offspring may be produced and th...
متن کاملMetformin prevents aggressive ovarian cancer growth driven by high-energy diet: similarity with calorie restriction
Caloric restriction (CR) was recently demonstrated by us to restrict ovarian cancer growth in vivo. CR resulted in activation of energy regulating enzymes adenosine monophosphate activated kinase (AMPK) and sirtuin 1 (SIRT1) followed by downstream inhibition of Akt-mTOR. In the present study, we investigated the effects of metformin on ovarian cancer growth in mice fed a high energy diet (HED) ...
متن کامل//Ovarian Aging
With age, there is a decline in both the quantity and quality of the pool of follicles and oocytes. Linear extrapolation of follicular depletion in women with regular menses predicts that, by 50 years of age, each ovary would contain 2500 to 4000 primordial follicles. Because the menopausal ovary is largely devoid of follicles, follicular depletion apparently accelerates in the last decade of r...
متن کاملGrape Seed Proanthocyanidin Extract Prevents Ovarian Aging by Inhibiting Oxidative Stress in the Hens
Oxidative stress is an important inducement in ovarian aging which results in fecundity decline in human and diverse animals. As a potent antioxidant, grape seed proanthocyanidin extract (GSPE) was investigated to ameliorate chicken ovarian aging in this study. Firstly, ovarian antioxidant capacity of hens at different ages (90, 150, 280, and 580 days old) was compared to elucidate its age-rela...
