目的 :探索恶性胸腹水上清中游离胸苷酸合成酶(TS)、β-tubulinⅢm RNA的表达,以及游离TS、β-tubulinⅢ表达和患者5-氟尿嘧啶(5-FU)、多西紫杉醇药物敏感性的关系。方法:收集43例进展期肿瘤患者的恶性胸/腹水,分离、提取游离核酸,分离...目的 :探索恶性胸腹水上清中游离胸苷酸合成酶(TS)、β-tubulinⅢm RNA的表达,以及游离TS、β-tubulinⅢ表达和患者5-氟尿嘧啶(5-FU)、多西紫杉醇药物敏感性的关系。方法:收集43例进展期肿瘤患者的恶性胸/腹水,分离、提取游离核酸,分离肿瘤细胞。实时荧光定量RT-PCR分别检测游离上清和肿瘤细胞中TS和β-tubulinⅢm RNA表达;ATP-TCA方法检测肿瘤细胞5-FU、多西紫杉醇的敏感性。结果:TS和β-tubulinⅢm RNA在恶性胸/腹水游离上清中的检出率为98%。与配对的肿瘤细胞相比,游离上清中TS m RNA表达水平高(P=0.02)。在胃肠肿瘤患者中,游离上清中TS m RNA表达水平与5-FU药物敏感性相关(P=0.002)。尽管观察到游离上清中β-tubulinⅢm RNA高表达者多西紫杉醇药物敏感性高的趋势,但差异没有统计学意义。结论:晚期肿瘤患者恶性胸腹水游离上清中可检测到游离TS、β-tubulin III m RNA的表达。在胃肠肿瘤患者中,游离上清TS m RNA表达水平与5-FU药物敏感相关。展开更多
