The results, presented in Table 1, revealed that the ABCB1-overexpressing human ovarian cancer cell line NCI-ADR-RES, the ABCB1-overexpressing human epidermal cancer cell line KB-V1, the ABCG2-overexpressing human colon cancer cell line S1-MI-80, and the ABCG2-overexpressing human NSCLC cell line H460-MX20, as well as their corresponding drug-sensitive parental cell lines showed equal sensitivity to furmonertinib. This evidence concerns the gene ABCB1 and non-small cell lung carcinoma.
