SRT2104 extends survival of male mice on a standard diet and preserves bone and muscle mass
نویسندگان
چکیده
Increased expression of SIRT1 extends the lifespan of lower organisms and delays the onset of age-related diseases in mammals. Here, we show that SRT2104, a synthetic small molecule activator of SIRT1, extends both mean and maximal lifespan of mice fed a standard diet. This is accompanied by improvements in health, including enhanced motor coordination, performance, bone mineral density, and insulin sensitivity associated with higher mitochondrial content and decreased inflammation. Short-term SRT2104 treatment preserves bone and muscle mass in an experimental model of atrophy. These results demonstrate it is possible to design a small molecule that can slow aging and delay multiple age-related diseases in mammals, supporting the therapeutic potential of SIRT1 activators in humans.

Background : Bone mineral density reduction is a problem that can lead to osteoporosis. Physical activity can be effective on the prevention of osteoporosis by some mechanisms such as changing in anthropometrics variables. The goal of this study was to evaluate bone mass density and some of anthropometrics variables and their relationship in athletes and non-athletes men. Methods : Thirty a...

Introdution: Muscle weakness that is caused by cancer called Cachexia. One of the causes of the formation of the cachexia is the change in protein degradation, and the ubiquitous protease and Autophagy Lysosomes system is the most important protein breakdown system. Resistance training has been one the best stimulator of increasing muscular mass. Therefore, the purpose of this study was to inve...

Background: Type 2 diabetes (T2D) in the elderly is an epidemic that has major impact on global health. Thus this experimental study aimed to compare the response of microRNA-133a (miR-133a) in different tissues and of Runt-related transcription factor 2 (Runx2) in bone marrow tissue following resistance and endurance training in old rats with high-fat diet and streptozotocin (HFD/STZ)-induced ...

Muscle atrophy is one of the consequences of aging and sports activities may prevent it. The aim of this study was to evaluate the effect of high intensity interval training on gene expression of Tweak and Fn14 in EDL muscle of aged C57bl/6 mice. For this purpose, 28 male C57bl/6 mice aged (n=14) and adult (n=14) were assigned in two groups of training (n=7) and control (n=7). After one-week fa...
