TranscriptomicsRNA-binding protein AUF1 promotes myogenesis by regulating MEF2C expression levels
The mammalian RNA-binding protein AUF1 (AU-binding factor 1, also known as heterogeneous nuclear ribonucleoprotein D, hnRNP D) binds to numerous mRNAs and influences their post-transcriptional fate. Given that many AUF1 target mRNAs encode muscle-specific factors, we investigated the function of AU...

TranscriptomicsComparison of the long-term effects of calorie restriction without malnutrition on global gene expression profiles of rat and human skeletal muscle [Rat]
With the population of older and overweight individuals on the rise in the Western world, there is an ever greater need to slow the aging processes and reduce the burden of age-associated chronic disease that would significantly improve the quality of human life and reduce economic costs. Caloric re...

TranscriptomicsSIRT1 but not its increased expression is essential for lifespan extension in caloric restricted mice.
The SIRT1 deacetylase is one of the best-studied potential mediators of some of the anti-aging effects of calorie restriction (CR); but its role in CR-dependent lifespan extension has not been demonstrated. We previously found that mice lacking both copies of SIRT1 displayed a shorter median lifespa...

TranscriptomicsThe SIRT1 activator SRT1720 extends lifespan and improves health of mice fed a standard diet
The prevention or delay of the onset of age-related diseases prolongs survival and improves quality of life while reducing the burden on the health care system. Activation of sirtuin 1 (SIRT1), an NAD+ deacetylase, improves metabolism and confers protection against physiological and cognitive distur...

TranscriptomicsSRT2104 extends survival of male mice on a standard diet and preserves bone and muscle mass
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 improve...
