New compound could reverse loss of muscle mass in cancer, other diseases
"Age-related loss of muscle mass is a major contributing factor to falls, broken bones, and the loss of mobility," says co-corresponding author David Glass of Novartis, Cambridge, MA, one of the compound’s developers, along with first author Estelle Trifilieff, also of Novartis. "This study illustrates that we may have a powerful tool to prevent muscle wasting and promote growth." The new compound (BYM338) acts to prevent muscle wasting by blocking a receptor that engages a cellular signaling system that exists to put the brakes on muscle development when appropriate. But sometimes those brakes are activated inappropriately, or are stuck on. "Our goal was to release the brakes," says Glass…
