MiR-1290 activates AKT/P70/FoxO3 signaling pathways during myoblast differentiation. a MHC staining performed after treated miR-1290/miR-NC with or without GDC-0068 (scale bar, 50 μm). b MHC-positive areas/total areas were quantified using Harmony 4.1 software (n = 6). cf The western blot analysis and quantification of phosphorylated and all forms of AKT and P70, MyoG, and MyoD, after transfecting miR-1290/miR-NC with or without GDC0068. GDC-0068 inhibited miR-1290-activated phosphorylation of AKT and P70 in C2C12 myoblasts. Western blot to analyze FoxO3 expression levels in cytoplasm and nucleus of C2C12 myoblasts. GAPDH and Lamin B1 are cytoplasmic and nuclear protein loading controls, respectively. The statistical difference among miR-1290 transfection group and inhibitor group were considered significant at the levels of *P < 0.05, **P < 0.01, or ***P < 0.001
