by Wiley Credit: CC0 Public DomainNew research indicates that some age-related changes in gene and protein expression in the skeletal muscles of older individuals may be affected more by physical inactivity and chronic inflammation than primary aging, or intrinsic maturational processes. Physical inactivity and chronic inflammation are the most important drivers of secondary aging, or changes...
by Hong Kong University of Science and Technology Fig. 1: Discordant proteomic and transcriptomic signatures reveal a potential translational control mechanism during the SC quiescence-to-activation transition. a Schematic illustration of the workflow for the proteomic analysis of FACS-isolated SCs. The SCs were sorted from Pax7-nGFP mice. QSCs were sorted from 0.5% PFA-perfused mice. fiSCs were...
by Cory Nealon, University at Buffalo The illustration shows a senescent muscle cell (left), including the numerous factors that led to its declining ability to divide and grow. It also shows the same type of cell after the overexpression of NANOG, which reversed many of the factors. Credit: University at Buffalo A University at Buffalo-led research team has...

Cross section of muscle shows extensive replacement of muscle fibers by adipose cells. Credit: Public Domain A UT Southwestern research team has cataloged gene activity in the skeletal muscle of mice, comparing healthy animals to those carrying a genetic...

GERMAN CANCER RESEARCH CENTER (DEUTSCHES KREBSFORSCHUNGSZENTRUM, DKFZ) PRINT E-MAIL In the fight against cancer or chronic infections, the immune system must be active over long periods of time. However, in the long run, the immune defence system often becomes exhausted. Scientists at the German Cancer Research Center (DKFZ) have now found initial evidence in mice...
Older men with sarcopenia are more likely to develop diabetes over time New findings point to age-related muscle loss as a contributing factor to diabetes in the elderly THE ENDOCRINE SOCIETY PRINT E-MAIL WASHINGTON–Older men who have lower lean body mass as they age are more prone to developing diabetes, while similar findings were not...
UNIVERSITY OF CALIFORNIA – IRVINE A new study led by researchers from the University of California, Irvine finds exercising in the morning, rather than at night, may yield better results. This study, published today in Cell Metabolism, points to daily timing as a critical variable for metabolic benefits from exercise and implications in chronobiology-based exercise therapy for patients with metabolic disorders. “Using mice, we compared the...
