Profiling non-small cell lung carcinoma cell line PC9 treated with erlotinib, KDM5A inhibitor, or viruses expressing KDM5 shRNAs or cDNA


ABSTRACT: The non-small cell lung carcinoma (NSCLC) PC9 cell line is an established preclinical model for tyrosine kinase inhibitors. Recent evidence suggests that KDM5A protein is required for emerging drug-resistant cell population. To better understand the dependence of cell survival on KDM5A, we treated EGFR-mutant PC9 cells with erlotinib, KDM5A inhibitor or KDM5A and KDM5B shRNAs and performed Drop-seq. We were able to clearly distinguish cells with KDM5A knockdown from cells with KDM5A overexpression. We were able to identify specific biomarkers associated with varying dose of KDM5A, for each cell population. The results of this study will address clinical usefulness of KDM5A-targeted strategies in overcoming drug resistance, particularly in NSCLC.
