摘要: As patients with non-small cell lung cancer (NSCLC) and wild-type epidermal growth factor receptor (EGFR) are resistant to treatment erlotinib or gefitinib, potential chemosensitizers required potentiate EGFR NSCLC cells erlotinib/gefitinib treatment. The present study reported that shikonin could sensitize the anticancer activity of in cells. Furthermore, mitochondrial-mediated apoptosis induced by In addition, demonstrated induce activating reactive oxygen species (ROS)-mediated endoplasmic reticulum (ER) stress, may also ER stress cells; however, plus was more effective than either agent alone. This indicated ROS-mediated be associated enhanced mitochondrial erlotinib/gefitinib. promote transition cytoprotective stress-inducing EGFR-tyrosine kinase inhibitor tolerance apoptosis-promoting stress. enhance anti-NSCLC vivo. data a sensitizer anti-cancer efficacy
