Acute exercise activates p38 MAPK and increases the expression of telomere‐protective genes in cardiac muscle

New Findings What is the central question of this study? A positive association between telomere length and exercise training has been shown in cardiac tissue of mice. It is currently unknown how each bout of exercise influences telomere‐length‐regulating proteins. We sought to determine how a bout of exercise altered the expression of telomere‐length‐regulating genes and a related signalling pathway in cardiac tissue of mice. What is the main...
