A, overexpression efficiency of miR-664-5p mimics at 0, 2, and 4 days. B, relative mRNA expression of MyoG and MyHC after induction for 4 days. C, protein expression of MyoG and MyHC after induction for 4 days. D, quantitative results of protein expression in C. E, immunofluorescence staining of MyHC after induction for 4 days. F, statistical results of the myoblast fusion index after induction for 4 days. G, differentiation index of myoblast after induction for 4 days. Values are expressed as the means ± S.E. (n = 3). *, p < 0.05; **, p < 0.01, versus NC.
