摘要 目的探讨透明质酸结合蛋白1(HABP1)在5种人卵巢癌细胞系中的表达及其对紫杉醇敏感性的影响。方法采用荧光定量RT-PCR法检测各细胞系中HABP1 mRNA的表达量,激光共聚焦显微镜观察HABP1蛋白的表达及定位,MTT法检测各细胞系对紫杉醇的敏感性。结果 HABP1 mRNA在人卵巢癌细胞系SKOV3、OVCA429和HO-8910PM中的表达水平分别是OVCA420的3.7、2.8和2.1倍(P均<0.05),HO-8910LM和OVCA420中HABP1 mRNA表达量差异无统计学意义(P均>0.05),HABP1蛋白在五种卵巢癌细胞系中的胞质中均有表达,在SKOV3、OVCA429和HO-8910PM细胞中可见到明显的核周聚集,在HO-8910LM和OVCA420中其核周聚集量明显减少,SKOV3、OVCA429、OVCA420、HO-8910PM和HO-8910LM细胞对紫杉醇的中效浓度分别为0.047、0.221、0.7230、.092、0.672μM,相关分析显示HABP1 mRNA表达水平与卵巢癌细胞对紫杉醇的中效浓度之间的相关系数为-0.888,P<0.05。结论 HABP1高表达能增加人卵巢癌细胞对紫杉醇的敏感性,HABP1可作为筛选卵巢癌化疗药物的新指标。
