Exercising lab-grown human muscle autonomously blocks the damaging effects of interferon gamma — ScienceDaily

Biomedical engineers at Duke University have demonstrated that human muscle has an innate ability to ward off the damaging effects of chronic inflammation when exercised. The discovery was made possible through the use of lab-grown, engineered human muscle, demonstrating the potential power of the first-of-its-kind platform in such research endeavors. The results appear online on […]

These Arctic squirrels recycle muscle proteins to survive winter

Arctic ground squirrels can survive harsh winters with below-freezing temps by holing up for some eight months without eating. These hibernators “live at the most extreme edge of existence, just barely hovering over death, and we don’t fully understand how this works,” says Sarah Rice, a biochemist at the University of Alaska Fairbanks. By snooping […]

Muscle cell secrets — ScienceDaily

A muscle fiber consists of just one cell, but many nuclei. A team at the MDC led by Professor Carmen Birchmeier has now shown just how varied these nuclei are. The study, which has been published in Nature Communications, can help us better understand muscle diseases such as Duchenne muscular dystrophy. Usually, each cell has […]

Molecule that regulates muscle adaptation to exercise is discovered

An article in Cell by researchers affiliated with Harvard and the University of São Paulo shows that the metabolite succinate is released by muscle cells during physical exercise and triggers a process of tissue remodeling that makes muscles stronger and enhances metabolic efficiency.

Molecule that promotes muscle health when magnetised

Associate Professor Alfredo Franco-Obregón and his team from the NUS Institute for Health Innovation and Technology examined how low amplitude magnetic fields may be used to enhance muscle metabolism. The images on the screen show the cells of two types of muscles—the blue fibres (left) are rapidly fatiguing muscles, the green fibres (right) are slowly […]
