1 Extracellular signal-regulated kinases (ERK1/2), c-Jun N-terminal kinases (JNK/SAPK), and p38 mitogen-activated protein kinase (MAPK) were all rapidly activated in a ROS-dependent manner during 2,3,5-tris-(glutathion-S-yl)hydroquinone (TGHQ)-mediated oxidative stress and oncotic cell death in renal proximal tubule epithelial cells (LLC-PK1). 2,3,5-(triglutathion-S-yl)hydroquinone mitogen-activated protein kinase 3 Homo sapiens

4 TGHQ-induced phosphorylation of ERK1/2 and JNK MAPKs required epidermal growth factor receptor (EGFR) activation, whereas p38 MAPK activation was EGFR independent. 2,3,5-(triglutathion-S-yl)hydroquinone mitogen-activated protein kinase 3 Homo sapiens
5 In contrast to their established roles in cell survival, TGHQ-activated ERK1/2 and p38 MAPK (but not JNK) appear to contribute to cell death, since inhibition of ERK1/2 or p38 MAPKs with PD098059 or SB202190 respectively, attenuated TGHQ-mediated cell death. 2,3,5-(triglutathion-S-yl)hydroquinone mitogen-activated protein kinase 3 Homo sapiens
