We next investigated the impact of CMTM6 on the steady‐state level of EGFR and its downstream signaling in NSCLC cells.[25] PC‐9, HCC827, and NCI‐H1975 cells were either transfected with empty vector or CMTM6 expression plasmid or treated with control siRNAs or CMTM6 siRNAs. The gene discussed is CMTM6; the disease is non-small cell lung carcinoma.
