Free radicals damage mitochondria

If you're an aging baby boomer hoping for a buffer physique, there's hope. A team of American scientists from Texas and Michigan have made a significant discovery about the cause of age-related muscle atrophy that could lead to new drugs to halt this natural process.

This research, available online the FASEB Journal, shows that free radicals, such as reactive oxygen species, damage mitochondria in muscle cells, leading to cell death and muscle atrophy. Now that scientists understand the cause of age-related muscle loss, they can begin to develop new drugs to halt the process.

"Age-related muscle atrophy in skeletal muscle is inevitable. However, we know it can be slowed down or delayed," said Holly Van Remmen, Ph.D., co-author of the study, from the Sam and Ann Barshop Institute for Longevity and Aging Studies at the University of Texas Health Science Center at San Antonio. "Our goal is to increase our understanding of the basic mechanisms underlying sarcopenia to gain insight that will help us to discover therapeutic interventions to slow or limit this process."

"I don't expect to see baby boomers gracing the pages of body building magazines tomorrow. But this research is important because it identifies molecules responsible for the aging of our muscles: free radicals," said Gerald Weissmann, M.D., Editor-in-Chief of the FASEB Journal. "Stop these from acting and we'll all look younger, stronger and fit at any age.

Bonnie - scientists do not have to come up with new drugs for mitochondrial damage because there is already a safe, natural substance that can protect against free radical damage. It is called Co-Enzyme Q10!
