Epigenetic responses to exertional heat stroke in mice: a potential link to long term Ca2+ dysregulation in skeletal muscle

Abstract

Exposure to extreme environments can induce a long‐term epigenetic memory of stress that is stored as altered DNA‐methylation and/or histone posttranslational modifications. These ultimately affect gene and protein expression as well as cellular functions. Exertional heat stroke (EHS) is a life‐threatening stress, but whether it induces epigenetic changes is unknown. Previous studies have suggested long‐term complications of EHS that could be mediated by epigenetics, including greater vulnerability to disease, heat stress susceptibility and disordered muscle Ca2+ signaling; the latter characterized as a malignant‐hyperthermia‐type muscle phenotype, based on the in vitro contracture test (IVCT).
