We recently reported crosstalk between Hippo/YAP and EGFR/extracellular signal‐regulated kinase signalling pathways in human NSCLC cells.19, 21 Collectively, PC9‐BrM3 cells are dependent on the EGFR signalling pathway and inhibiting that pathway can inhibit the YAP signalling pathway and control metastasis of PC9‐BrM3 cells. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
