Effects of PYCP supplementation on the autophagy-lysosome system in gastrocnemius muscle. (A,B) Cathepsin-L mRNA and protein levels were assessed with real-time PCR and Western blot analysis; (C,D) protein levels of autophagy-related genes (i.e., LC3-I/LC3-II, BECN1, ATG5, ATG7, ATG12, and p62/SQSTM1) assessed by Western blot analysis. GAPDH was used as an internal standard. Data represent mean ± standard deviation of three independent experiments (n = 5/group). * p < 0.05, ** p < 0.01, *** p < 0.001 vs. the corresponding control group; #
p < 0.05, ##
p < 0.01, ###
p < 0.001 vs. the corresponding DEX-only treatment group.
