Sex‐Specific Early Life Corticosterone Stress‐Coping Capacity Is Linked to Mitochondrial Content and Telomere Maintenance

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Glucocorticoids are upregulated during acute challenges, contributing to maintenance of energy balance. However, if this upregulation exceeds a threshold or becomes chronic, it can lead to harmful effects. Investigating the factors behind between‐individual variation in the magnitude of the response to acute stress and how effectively ...
