Breast cancer resistance protein (BCRP/ABCG2), an ATP binding cassette half-transporter, confers resistance to mitoxantrone, doxorubicin, and topoisomerase I inhibitors of irinotecan and topotecan. Recently, we reported that BCRP efficiently transported SN-38 (the active metabolite of irinotecan) with a high affinity in lung cancer cells in vitro (K. Nakatomi et al., Biochem. Biophys. Res. Commun., 288: 827-832, 2001). The aim of this study is to explore the role of BCRP in the drug resistance of lung cancer. Experimental Design: The BCRP mRNA expression in lung cancer cells and 23 untreated non-small cell lung cancer (NSCLC) tissues was quantitated by real-time reverse transcription-PCR. To evaluate the drug-efflux function of BCRP, the intracellular topotecan accumulation and drug sensitivity were measured in lung cancer cells with various levels of the BCRP mRNA expression by flow cytometric and tetrazolium dye assay, respectively.
