MGr-l possesses function of reversing MDR by increasing intracellular adriamycin accumulation and retention, suggesting that MGr-1 Ag may respresent another mechanism responsible for MDR in VCR-resistant human gastric cancer cell line (SGC7901/VCR).

• MGr－1具有通过增加细胞内药物蓄积及潴留逆转SGC7901/VCR细胞耐药性的功能。 提示MGr－1所对应的细胞膜抗原可能为一种新的有活性功能并与MDR相关的分子。
