Scientists discover a compound that could supercharge aging muscle repair
Scientists may have created a “Super HGF” that helps aging muscles repair themselves more powerfully.
A sulfur-based compound called LASSS appears to protect and supercharge a key protein involved in repairing damaged muscle. The discovery could eventually lead to new ways to slow muscle loss and preserve strength as people age.
Skeletal muscle often begins to deteriorate relatively early in the aging process. Over time, this can cause loss of strength, increased scarring, fat buildup within muscle tissue, and a decline in fast twitch fibers, which support rapid and powerful movements.
The research focuses on hepatocyte growth factor, or HGF, a protein that helps initiate the repair of skeletal muscle. Under normal conditions, HGF remains inactive within the structural network surrounding muscle fibers.
When muscle tissue is injured or exposed to mechanical stimulation, HGF is released. It then attaches to c met receptors on satellite cells, the stem cells responsible for maintaining and repairing skeletal muscle. This signal brings the cells out of their inactive state, allowing them to multiply, mature, and help rebuild damaged muscle fibers.
What this tells us is that LASSS does more than simply neutralize reactive molecules. It may interact directly with HGF and induce a subtle structural change, creating an enhanced 'Super HGF' form that binds c-met more strongly and resists nitration."
The findings suggest that LASSS may directly alter the structure of HGF in a beneficial way. Rather than acting only as an antioxidant, the compound may create a more active form of the protein that connects more strongly with its receptor while resisting chemical damage.
