The mean ± SEM mRNA expression of antioxidant-related genes (a), mTOR (b) and protein degradation-related genes (c) in the breast muscle of control and EP-Zn supplemented broiler chickens. * and ** indicate significant difference at P < 0.05 and P < 0.01, respectively. mTOR: mechanistic target of rapamycin; PROTC1: 20S proteasome C1 subunit; MC1P: m-Calpain large subunit
