1 Orientin-mediated Nrf2/HO-1 signal alleviates H2O2-induced oxidative damage via induction of JNK and PI3K/AKT activation. Hydrogen Peroxide nuclear factor, erythroid derived 2, like 2 Mus musculus
2 Our findings suggested that Ori exposure effectively alleviated H2O2-stimulated cytotoxicity, inhibited reactive oxygen species (ROS) generation, and glutathione (GSH) depletion, which were involved in induction of heme oxygenase-1 (HO-1) by enhancing the nuclear factor-erythroid 2-related factor 2 (Nrf2) translocation, decreasing the Keap1 protein expression, and increasing the antioxidant response element (ARE) activity. Hydrogen Peroxide nuclear factor, erythroid derived 2, like 2 Mus musculus

4 However, knockdown of Nrf2 and HO-1 with siRNA mostly abolished the cytoprotective effects against H2O2-induced cell oxidative injury, reduced the expression of Nrf2 and HO-1, respectively. Hydrogen Peroxide nuclear factor, erythroid derived 2, like 2 Mus musculus
5 However, knockdown of Nrf2 and HO-1 with siRNA mostly abolished the cytoprotective effects against H2O2-induced cell oxidative injury, reduced the expression of Nrf2 and HO-1, respectively. Hydrogen Peroxide nuclear factor, erythroid derived 2, like 2 Mus musculus
6 Taken together, Ori might exhibit a protective role against H2O2-stimulated oxidative damage by the induction of HO-1 expression through the activation of the JNK- and PI3K/AKT-Nrf2 signaling pathways. Hydrogen Peroxide nuclear factor, erythroid derived 2, like 2 Mus musculus
