Abstract

In this study, it was demonstrated that 1,3-dichloro-2-propanol (1,3-DCP) induced oxidative stress and cell death in HuH7, human hepatocytes. The protective effects of Erythronium japonicum (E. japonicum) and Corylopsis coreana Uyeki (C. coreana Uyeki) extracts against 1,3-DCP-treated cells were also investigated. First, the activities of superoxide dismutase (SOD) and catalase (CAT) were diminished by the treatment of 1,3-DCP. Moreover, 1,3-DCP stimulated the expression and catalytic activity of cytochrome P450 2E1 (CYP2E1), an enzyme that generates reactive oxygen species in the liver. In contrast, co-treatment of 1,3-DCP with the extracts significantly decreased ROS generation and inhibited CYP2E1 activity without affecting its expression. The co-administration of extracts also restored the activities of SOD and CAT reduced by 1,3-DCP and protected against 1,3-DCP-mediated cell death. In conclusion, these results suggest that 1,3-DCP induces oxidative stress through the elevated CYP2E1 level, which is inhibited by the extracts, protecting cells against the effects of 1,3-DCP.
