Similarly, the ABCG2-overexpressing multidrug-resistant H460-MX20 human lung cancer cells, S1-M1-80 human colon cancer cells, ABCG2-transfected R482-HEK293 cells, and the corresponding drug-sensitive parental H460, S1 and pcDNA-HEK293 cells are also equally sensitive to erdafitinib treatment. Here, ABCG2 is linked to colonic neoplasm.
