Growing evidence suggests that activation of mitogen-activated protein kinase (MAPK) signal transduction mediates changes in muscle gene expression in response to exercise. Nevertheless, little is known about upstream or downstream regulation of MAPK in response to muscle contraction. Here we show that ex vivo muscle contraction stimulates extracellular signal-regulated kinase 1 and 2 (ERK1/2), and p38MAPK phosphorylation. Phosphorylation of ERK1/2 or p38MAPK was unaffected by protein kinase C inhibition (GF109203X), suggesting that protein kinase C is not involved in mediating contraction-induced MAPK signaling. Contraction-stimulated phosphorylation of ERK1/2 and p38MAPK was completely inhibited by pretreatment with PD98059 (MAPK kinase inhibitor) and SB203580 (p38MAPKinhibitor), respectively. Muscle contraction also activated MAPK downstream targets p90 ribosomal S6 kinase (p90Rsk), MAPK-activated protein kinase 2 (MAPKAP-K2), and mitogen- and stress-activated protein kinase 1 (MSK1). Use of PD98059 or SB203580 revealed that stimulation of p90Rsk and MAPKAP-K2 most closely reflects ERK and p38MAPK stimulation, respectively. Stimulation of MSK1 in contracting skeletal muscle required the activation of both ERK and p38MAPK. These data demonstrate that muscle contraction, separate from systemic influence, activates MAPK signaling. Furthermore, we are the first to show that contractile activity stimulates MAPKAP-K2 and MSK1.
