Epigenetic mechanisms in stress and adaptation [PDF]

open access: yesBrain, Behavior, and Immunity, 2011
Epigenetic mechanisms are processes at the level of the chromatin that control the expression of genes but their role in neuro-immuno-endocrine communication is poorly understood. This review focuses on epigenetic modifications induced by a range of stressors, both physical and psychological, and examines how these variations can affect the biological ...

Potential mechanisms involved in regulating muscle protein turnover after acute exercise: A brief review

open access: yesFrontiers in Physiology, 2023
It is well established that resistance training increases muscle mass. Indeed, there is evidence to suggest that a single session of resistance training is associated with an increase in muscle protein synthesis in young adults.
