【摘要】:正[Background] Induction of heme oxygenase-1 (HO-1) expression has been associated with cytoprotective and anti-inflammatory actions of lansoprazole, a proton pump inhibitor, but the underlying molecular mechanisms remain largely unresolved. In this study, we investigate the role of transcriptional factor Nrf2, its phosphorylation/activation, and oxidation of Keap-1 in lansoprazole-induced HO-1 up-regulation using cultured gastric epithelial
