Life expectancy at the turn of the 20th century was 46 years on average worldwide and it is around 65 years today. The correlative increase in age-associated diseases incidence has a profound public health impact and is an important matter of concern for our societies. Aging is a complex, heterogeneous, and multifactorial phenomenon, which is the consequence of multiple interactions between genes and environment. In this review, we survey animals models that have been of great help for both investigating mechanism of aging and identifying molecules, which slow down the onset of age-related diseases. Resveratrol (RSV) is one of those. We will report evidences supporting RSV as a molecule that acts by mimicking the beneficial effects of dietary restriction, and may share common downstream targets with rapamycin and metformin. Although those molecules do not reveal all the secrets of the fountain of youth, they may help us maintaining the quality of life in the old age. © 2010 International Union of Biochemistry and Molecular Biology, Inc.

Autophagy-dependent longevity models in C. elegans display altered lipid storage profiles, but the contribution of lipid distribution to life span extension is not fully understood. Here we report tha...
After nearly a century of rigorous investigation and testing, dietary caloric restriction (CR) remains the most robust and reproducible method for slowing aging and maintaining health, function, and v...
The mechanistic target of rapamycin complex 1 (mTORC1) signaling pathway is hyperactivated in a variety of cancers and tumor syndromes. Therefore, mTORC1 inhibitors are being actively investigated for...
Resveratrol (RES) has been studied for its effects on the lifespan extension of Caenorhabditis elegans, but controversy still remains on its mechanism related with SIR-2. In this study, longevity assa...
Metformin is a commonly used antidiabetic drug. It has been shown that this drug activates the AMP-activated protein kinase, which inhibits downstream the mammalian target of rapamycin. In addition, s...
Resveratrol is purported to possess cancer preventive activity, especially for colon cancer, though its mechanisms of action are not well defined. Resveratrol is found in the skin of grape...
The main objective of the study is to investigate if 6 months resveratrol supplementation can improve glucose tolerance in individuals with impaired glucose homoeostasis. As secondary obje...
The purpose of this research study is to evaluate the effects of combining physical exercise with a resveratrol supplementation on the physical function of older adults.
The investigators aim to conduct a randomized placebo controlled pilot study to determine whether resveratrol, a dietary ingredient, supplementation is safe and improves memory and physica...
Resveratrol, a compound found in red wine and dark-skinned grapes, will improve the function of mitochondria (energy producing components) within the leg muscles of moderate functioning ol...
A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289)
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
Component of the NATIONAL INSTITUTES OF HEALTH. It conducts and supports clinical and basic research to establish a scientific basis for the care of individuals across the life span, from the management of patients during illness and recovery to the reduction of risks for disease and disability; the promotion of healthy lifestyles; the promotion of quality of life in those with chronic illness; and the care for individuals at the end of life. It was established in 1986.
Calcium compounds used as food supplements or in food to supply the body with calcium. Dietary calcium is needed during growth for bone development and for maintenance of skeletal integrity later in life to prevent osteoporosis.
A family of the order DIPTERA. These flies are generally found around decaying vegetation and fruit. Several species, because of their short life span, giant salivary gland chromosomes, and ease of culturing, have been used extensively in studies of heredity.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
