Figure Lengend Snippet: A Western blot analyses of integrin αV, integrin β5 and GAPDH in Dex and irisin-administered myotubes. B Protein levels were analyzed, n = 4 independent replicates. C Western blot analyses of P-ERK, P-GR(Ser212), P-JNK (Thr183/Tyr185), P-GR(Ser234), IGF-1, MSTN and GAPDH in integrin αVβ5 inhibitor cliengitide treatment myotube. D – I Protein levels were analyzed, n = 4 independent replicates. Data are presented as means ± SEM. One-way ANOVA was used for statistical analysis ( B ), Two-way ANOVA was used for statistical analysis ( D – I ).
