ABCG2 and non-small cell lung carcinoma: In the present study, we mapped the expression of 48 human ABC transporters in the gefitinib-sensitive and -resistant NSCLC cell lines using RNA sequencing technology, and found that ABCC10 (ATP binding cassette subfamily C member 10), also known as MDR protein 7 (MRP7), was significantly upregulated in cells with acquired resistance to gefitinib.
