High density-induced stress on the cortisol signaling pathway in skeletal muscle. Relative expression (fold change) of (a) corticosteroid receptors gr1, gr2 and mr (b) GR target genes: redd1, klf15, and hsp70 normalized with fau and β-actin. Results are shown as the means ± SEM (n = 5 per group). LD, low stocking density; HD, high stocking density. Significant differences are indicated with a line (* = P < 0.05; ** = P < 0.01)
