1 Calpastatin overexpression in the skeletal muscle of mice prevents clenbuterol-induced muscle hypertrophy and phenotypic shift. Clenbuterol calpastatin Mus musculus
2 Using gene electrotransfer of a calpastatin expression vector into the tibialis anterior of adult mice, we found that calpastatin overexpression attenuates muscle hypertrophy and phenotypic shifts induced by clenbuterol treatment. Clenbuterol calpastatin Mus musculus
3 In conclusion, the results support the contention that the calpain/calpastatin system plays a crucial role in skeletal muscle hypertrophy and phenotypic shifts under chronic clenbuterol treatment, with AMPK and CamK2 probably playing a minor role. Clenbuterol calpastatin Mus musculus
4 Moreover, the calpastatin-induced inhibition of hypertrophy under clenbuterol treatment was not related to a decreased mTOR-dependent initiation of protein translation. Clenbuterol calpastatin Mus musculus
