Mitogen-activated protein kinases (MAPKs) mediate SIN-1/ glucose deprivation-induced death in rat primary astrocytes.

Peroxynitrite is a potent neurotoxic molecule produced from a reaction between NO and superoxide and induces NO-mediated inflammation under neuropathological conditions. Previously, we reported that glucose deprivation induced ATP depletion and cell death in immunostimulated astrocytes, which was mainly due to peroxynitrite. In this study, the role of MAPKs (ERK1/2, p38MAPK, and JNK1SAPK) signal pathway in the SIN-1/glucose deprivation-induced death of astrocytes was examined.
