Abstract

Human epidermal growth factor receptor 2 (HER2) is a member of the ErbB family of receptor tyrosine kinases. Numerous studies have reported the amplification and overexpression of HER2 in several types of cancer, including non‑small cell lung cancer (NSCLC). However, the benefits of HER2‑targeted therapy have not been fully established. In the present study, the anti‑tumor effect of neratinib, an irreversible pan‑HER tyrosine kinase inhibitor (TKI), against NSCLC cells harboring HER2 alterations was investigated. The sensitivity of normal bronchial epithelial cells (BEAS‑2B) ectopically overexpressing wild‑type or mutant HER2 to neratinib was assessed. Furthermore, the anti‑tumor activity of neratinib in several NSCLC cell lines harboring HER2 alterations was determined in vitro and in vivo, and the association between their genetic alterations and sensitivity to neratinib treatment was investigated. BEAS‑2B cells ectopically overexpressing wild‑type HER2 or mutants (A775insYVMA, G776VC, G776LC, P780insGSP, V659E, G660D and S310F) exhibited constitutive autophosphorylation of HER2, as determined by western blotting. While these BEAS‑2B cells were sensitive to neratinib, they were insensitive to erlotinib, a first‑generation epidermal growth factor receptor‑TKI. Neratinib also exerted anti‑proliferative effects on HER2‑altered (H2170, Calu‑3 and H1781) NSCLC cell lines. Neratinib was also demonstrated to exert strong tumor growth inhibitory activity in mouse xenograft models using HER2‑altered lung cancer cells. The results of the present study strongly suggest that neratinib has potential as a promising therapeutic option for the treatment of HER2‑altered NSCLC.
