The effect of alpha lipoic acid on serum testosterone levels in chickens exposed to heat stress. (A) Serum testosterone concentration was determined using a commercial ELISA kit. (B) Western blotting was used to analyze the expression of the key steroidogenic-related proteins, StAR and 3β-HSD. (C) StAR and (D) 3β-HSD protein expression levels were normalized to β-actin levels. The statistical analysis results are shown as bar graphs. The data are presented as the mean ± SE of three independent experiments. Note: * p < 0.05 vs. HS group; # p < 0.05 vs. C group.
