Figure Lengend Snippet: Western blotting analysis of proteins involved in the regulation of skeletal muscle mass and function. ( A ) Representative bands of each protein assessed by Western blot (MW = molecular weight). ( B – D ) Densitometry of total HDAC4, phospho (Ser632) HDAC4, and the ratio of phospho/total HDAC4 protein levels. ( E ) Densitometry of MuRF1 protein levels. ( F ) Densitometry of MuRF2 protein levels. ( G – I ) Densitometry of total FoxO1, phospho (Ser256) FoxO1, and the ratio of phospho/total FoxO1 protein levels. ( J – L ) Densitometry of total Akt, phospho (Ser473) Akt, and the ratio of phospho/total Akt protein levels. Data are shown as mean ± standard error of the mean (* p < 0.05 vs. Sham12h, # p < 0.05 vs. DNV12h + VEH, n = 5–7).
