Since in PC‐9/GR/AR cells the combination of HNK and Osim clearly enhanced the levels of Bim, another critical molecule in mediating Osim‐induced apoptosis in sensitive EGFR‐mutant NSCLC cells (Shi et al., 2017), we determined whether enhanced Bim elevation contributes to the augmented induction of apoptosis by the HNK and Osim combination. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
