α/β CaMKII co-overexpression increases MHCIIA/X but not mitochondrial protein. A, C) Immunodetection of fast type myosin heavy chain (MHCII) (A) and ANXV (C) in homogenate from a control-transfected (1) and α/β CaMKII-transfected (2) SOL muscle pair. Below loading control visualizing skeletal alpha actin (skaa). B, D) Bar graph visualising the mean + SE of MHCA/IIX and MHC IIB (B) and ANXV protein content (D) in control-transfected (light grey filled bar) and α/β CaMKII-transfected (dark grey filled bar) SOL muscle (n = 9). *, p ≤0.05 vs. control-transfected (Wilcoxon test).
