  • OxidativeStressInducedGeneExpressionViaNrf2

    Reactive oxygen species (ROS) can damage biological macromolecules and are detrimental to cellular health. Electrophilic compounds, xenobiotics and antioxidants are sources of reactive oxygen species, creating oxidative stress that can harm cells. Enzymes are involved in the Phase II detoxification of xenobiotics to reduce cellular stress include glutathione transferases, quinone reductase, epoxide hydrolase, heme ox......閱讀全文
