Abstract:
Objective To determine the effect of tumor necrosis factor ?(TNF ?) on p38 mitogen activated protein kinase (MAPK) activation in human pulmonary microvascular endothelial cells (HPMEC) in vitro Methods HPMEC was isolated and cultured in vitro Expression and activation of p38 MAPK were detected by western blot and immune complex kinase assay Results TNF ? induced phosphorylation and activation of p38 MAPK in HPMEC in a time/dose dependent manner which was suppressed by SB203580,a specific inhibitor of p38 MAPK Conclusion TNF ? plays a important role in activation of p38 MAPK and signal transduction in HPMEC
