Key to Longevity: New Compound Fights Muscle Aging

Muscle, often a symbol of fitness, plays a crucial role in longevity, supporting blood sugar control, circulation, and mobility. However, a significant decline in muscle mass and repair capacity is a common aspect of aging. Recent research suggests the issue isn't just muscle loss, but a chemical 'rusting' of the internal signal that triggers muscle repair.

At the core of this system is hepatocyte growth factor (HGF), which activates stem cells to repair muscle fibers. With age, HGF undergoes a process called nitration, altering its structure so it can no longer effectively bind to stem cells. This hinders muscle repair, leading to weakening and scarring.

Scientists at Kyushu University identified LASSS, a sulfur-based compound, which not only protects HGF from this damage but also enhances its function, creating a 'Super HGF'. In lab tests and mouse models, LASSS significantly improved HGF's binding ability and resistance to chemical damage, outperforming other tested compounds.

While further human studies are needed, this discovery offers a new perspective on age-related muscle decline. Beyond traditional methods like resistance training and protein intake, LASSS-like therapies could potentially preserve muscle repair capacity, benefiting both humans and companion animals.
