EGFR and non-small cell lung carcinoma: Because sulforaphane appeared to exhibit a greater anti-proliferative effect in TKI-resistant NSCLC cells harboring mutant EGFR (H1975 and PC9/gef) than wild-type EGFR (A549) (Fig. 1 and Table 1), we hypothesized that suforaphane might interfere with the EGFR signaling.
