Elevated autophagy signaling protein expression in skeletal muscle of R6/2 mice. Western blot analysis of LC3B-I and II, Beclin-I, and atg5 and -7 in gastrocnemius and the change (R6/2 vs. WT mice) expressed as a fold change or percentage are shown. NS, not significantly different. ↑, P < 0.05, n = 8/group. α-tubulin as a loading control was also shown.
