Outline of Final Research Achievements

We have the first time observed that cardiotoxin-injury results an increase in new growth factor-x (GFX) gene and protein expression in the muscles. Neutralizing antibody against GFX impaired muscle function recovery and aggravated interstitial fibrosis and muscle stem cell homing into the muscle in response to cardiotoxin; these changes were mitigated by the mouse recombinant GFX intervention. These findings suggest that GFX might be new therapeutic target for the injury-related muscle disease like Sarcopenia and frailty.
