HMOX1 and liver dysplastic nodule: Further mechanistic studies demonstrated that LCB treatment upregulates the expressions of heme oxygenase-1 (HO-1) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2), suggesting activation of the Nrf2/HO-1 signaling pathway.<h4>Conclusion</h4>Taken together, this research demonstrates that LCB suppresses oxidative stress and apoptosis accompanied by modulating the Nrf2/HO-1 pathway to ameliorate DN, which provides a promising strategy for DN treatment.
