To study biological consequences of KDM1A up-regulation in NSCLC cells with different oncogenic driver mutations, we examined KDM1A expression in multiple NSCLC cell lines, including PC9, PC9R, H1650, H292, H1975, 95D, HCC827, and A549 cells, and found that KDM1A expression varied considerably among these cells. This evidence concerns the gene KDM1A and non-small cell lung carcinoma.
