目的研究醛糖还原酶相似蛋白(aldose reductase like protein,ARL-1)在肝癌细胞中的功能及ARL-1基因高表达与肝癌耐药之间的关系.方法通过阳离子脂质体转染法将ARL-1基因导入HepG2细胞,建立稳定表达该基因的细胞株,采用MTT法检测细胞对含醛基药物的耐药变化情况.结果转染细胞与未转染细胞相比,对含醛基的抗肿瘤药物如阿霉素、丝裂霉素的耐药性明显增强,其半数抑制浓度(IC50)分别提高到2.6倍和3.1倍,ADM组t=6.39,P＜0.05,MMC组t=30.06,P＜0.01.用不含醛基的5-氟尿嘧啶处理两组细胞,则未发现有明显的耐药差异(t=0.684,P＞0.05).结论ARL-1的表达上调可能是肿瘤细胞对含醛基抗肿瘤药物耐药的主要原因...

OBJECTIVE: To investigate the relationship between aldose reductase like protein (ARL-1) gene overexpressed in HCC cells and drug-resistance of the cell to drugs containing carbonyl group. METHODS: To establish ARL-1 stable expression positive cell line, eukaryotic expression vectors containing ARL-1 gene cDNA were transfected into Hep cell mediated by lipofect AMINE. The positive monoclones were determined by PCR and RT-PCR, respectively. Then MTT assay was used to study the drug resistance ability of the cells to drugs containing carbonyl after incubating three days with those drugs. RESULTS...
