Profiling non-small cell lung carcinoma cell line PC9 treated with erlotinib using 10x Genomics


ABSTRACT: The non-small cell lung carcinoma (NSCLC) PC9 cell line is an established preclinical model for tyrosine kinase inhibitors. To be able to better understand the differences in response between individual cells, we performed treatment of PC9 cells grown in cell culture with erlotinib followed by 10x Genomics. We were able to clearly distinguish cells that were treated with the drug from untreated cells, and we discovered different cell populations within the treated cells, likely reflecting heterogeneity of drug resistant cells. We were able to identify specific biomarkers, as preferentially expressed genes, for each cell population. The results of our study will address preexisting and acquired drug resistance that limits clinical usefulness of targeted strategies, particularly in NSCLC.
