Upregulation of GPX4 mRNA expression has been observed in vitro in EGFR‐TKI‐induced DTP cells in EGFR+ NSCLC, and combination treatment with EGFR‐TKI plus GPX4 inhibitor was found to prevent growth of EGFR+ NSCLC cells in vitro [42]. The gene discussed is GPX4; the disease is non-small cell lung carcinoma.
