1 AIM: To investigate the protective effect of heme oxygenase-1 (HO-1) against H2O2-induced apoptosis in human ARPE-19 cells. Hydrogen Peroxide heme oxygenase 1 Homo sapiens
2 AIM: To investigate the protective effect of heme oxygenase-1 (HO-1) against H2O2-induced apoptosis in human ARPE-19 cells. Hydrogen Peroxide heme oxygenase 1 Homo sapiens
3 METHODS: The lentiviral vector expressing HO-1 was prepared and transfected into apoptotic ARPE-19 cells induced by H2O2. Hydrogen Peroxide heme oxygenase 1 Homo sapiens
4 It was found that exogenous HO-1 significantly ameliorated H2O2-induced loss of cell viability, apoptosis and intracellular levels of reactive oxygen species (ROS) in ARPE-19 cells. Hydrogen Peroxide heme oxygenase 1 Homo sapiens
5 Furthermore, HO-1 upregulation further inhibited H2O2-induced release of cysteinyl aspartate specific proteinase-3 (caspase-3). Hydrogen Peroxide heme oxygenase 1 Homo sapiens
6 CONCLUSION: Exogenous HO-1 protect ARPE-19 cells against H2O2-induced oxidative stress by regulating the expressions of Nrf2, HO-1, Bcl-2, and caspase-3. Hydrogen Peroxide heme oxygenase 1 Homo sapiens
