Abstract

The JAK/STAT signaling pathway is essential for myogenic regeneration and is regulated by a diverse range of ligands, including interleukin-6 (IL-6) and platelet-derived growth factor-BB (PDGF-BB). Our aim was to evaluate the responsiveness of IL-6 and PDGF-BB to intense exercise, along with STAT3 activation, before and after 12 weeks of resistance training. In young men, IL-6 and PDGF-BB protein concentrations were quantified in biopsied muscle and increased at 3 h post-exercise (17.5-fold and 3-fold, respectively). The response was unaltered by 12 weeks of training. Similarly, STAT3 phosphorylation was elevated post-exercise (12.5-fold), irrespective of training status, as was the expressi..
