To assess the reproducibility of MTCH2 silencing across different primary NSCLC cells, lentiviral vectors expressing shMTCH2-S1 were introduced into primary human NSCLC cells from other two patients, specifically pNSCLC-2, pNSCLC-3, and also into the A549 immortalized cell line. This evidence concerns the gene MTCH2 and non-small cell lung carcinoma.
