Raised levels of heat shock proteins can protect against sarcopenia, age-related loss of muscle mass and strength: "HSP10 (Heat Shock Protein), helps monitor and organise protein interactions in the body, and responds to environmental stresses, such as exercise and infection, by increasing its production inside cells. Researchers [found] that excessive amounts of HSP10 inside mitochondria - 'organs' that act as energy generators in cells - can [preserve] muscle strength. ... We studied the role of HSP10 inside mitochondria, as it is here that unstable chemicals are produced which can harm parts of the cell. The damage caused by this is thought to play an important part in the ageing process, in which skeletal muscle becomes smaller and weaker and more susceptible to stress damage. In response to these stresses HSP10 increases its levels and helps cells resist damage and recover more effectively. Our research is the first to demonstrate that age-related loss of skeletal muscle mass is not inevitable." The article is sadly sensationalist, overhyping a slowing of muscle loss as "halting the aging process" when it is of course no such thing. It is unfortunate that university publicists feel the need to do this - it only makes them and the researchers they promote look foolish.
