Summary 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 expression of downstream targets c-MYC (8-fold), c-FOS (4.5-fold), and SOCS3 (2.3-fold). Thus, intense exercise transiently increases IL-6 and PDGF-BB proteins, and STAT3 phosphorylation is increased. These responses are preserved after intense exercise. This suggests they are not modified by training and may be an essential component of the adaptive responses to intense exercise.
