Effects of 2% turmeric extract (TE) supplementation on gene and protein expression of atrophy-related factors in the tibialis anterior muscle of dexamethasone (DEX)-treated mice. (a) Gene expression of Fbxo32, Murf1, FoxO1, and FoxO3. (b) Protein expression of FBXO32 and MuRF1. (c,d) are the correlation between mRNA and protein expression of FBXO32 and MuRF1. The results are shown as the mean ± standard error and statistical analysis was performed by Tukey–Kramer test. The correlation test was performed by Pearson correlation test. Control group: n = 7; DEX and DEX + TE groups: n = 6 each in the PCR experiment and n = 4 in Western blotting. * p < 0.05, ** p < 0.01 vs. Control, # p < 0.05, ## p < 0.01 vs. DEX, N.S.: not significant.
