Chronic Cortisol Exposure Reshapes Chromatin Accessibility and Gene Expression: Implications for Growth and Welfare in Rainbow Trout (Oncorhynchus mykiss)
Cortisol, the principal glucocorticoid in teleosts, coordinates the physiological response to stress by regulating metabolism, protein turnover, and growth. Although the molecular effects of acute cortisol exposure have been extensively characterized, the epigenomic mechanisms underlying skeletal muscle remodeling duri...
