A Human ABCG2 SNP Variant, P269S (rs34678167, c.805C>T), Increases Cellular Resistance to Mitoxantrone and SN-38 Without Detectable Differences in ABCG2 Abundance in Total and Biotinylated Protein Fractions
ABCG2 (BCRP/MXR) is an ATP-binding cassette transporter that plays a role in cellular resistance to various anticancer agents. While several non-synonymous single-nucleotide polymorphisms (SNPs) in the ABCG2 gene have been functionally characterized, the effects of many variants remain uncertain. This study examined th...
