Nerve growth factor-induced myoprotection in C2C12 muscle cells is mediated by α9β1 integrin via release of PGE2
AbstractNerve growth factor (NGF) mediates a wide range of activities in the central nervous system including neuronal differentiation, synaptic plasticity, and neuroprotection. In addition, NGF places an important role in skeletal muscle physiology by some unknown mechanisms. We recently demonstrated that NGF conferred myoprotection toward ischemia in C2C12 skeletal muscle cell model, establishing an important trophic role for NGF in skeletal muscle.In this report, using ELISA and oxygen-glucose deprivation (OGD) assays, we investigated the potential contribution of prostaglandin ENGF-induced mitogen-activated protein kinase type 1 or 2 (ERK1/2) phosphorylation in C2C12 cells and in a dose-response fashion stimulated PGEThese results suggest that NGF activation of α9β1 integrin induced myoprotection by stimulation of ERK phosphorylation and release of cytoprotective PGE
