| Research Abstract |
To investigate novel mechanisms of resistance to EGFR-TKI in lung cancer, we examined expression levels of HER-family ligands and phosphorylation status of HER-family receptors in EGFR-TKI primary and acquired resistant NSCLC cell lines. HER3 and HER4 binding ligands were highly expressed in primary resistant cell lines. Phosphorylation status of HER4 and its downstream STAT5 were increased in acquired resistant cell lines.
