Role of MyoD in denervated, disused, and exercised muscle.

abstract：INTRODUCTION:Previous studies of limb-girdle muscular dystrophy type 2A (LGMD2A) patients in many countries have suggested a heterogeneous genetic and clinical spectrum, but the genotypes and phenotypes of Chinese LGMD2A patients remain unclear. METHODS:We directly screened calpain-3 (CAPN3) in 18 Chinese Han subjects...
