趋化因子配体10及趋化因子受体3在膀胱癌中的表达及意义

摘要

目的：检测趋化因子配体10(CXCL10)及趋化因子受体3(CXCR3)在膀胱癌中的表达并探讨其临床意义。方法80例膀胱癌患者和33例健康体检者分别纳入试验组和对照组。采用 ELISA 检测血清中 CXCL10的表达，采用逆转录-聚合酶链反应(RT-PCR)法检测外周血单一核细胞中 CXCR3 mRNA 的表达，并将 CXCL10和 CXCR3的表达强度与各临床参数进行相关性分析。结果试验组外周血清中 CXCL10及外周血单一核细胞中 CXCR3 mRNA 的表达量均显著高于对照组；试验组血清CXCL10及 CXCR3 mRNA 的表达与年龄、病理分期、分化程度、肿瘤大小等均不存在相关性(P >0.05)，但均与有无淋巴结转移相关(P <0.05)。结论CXCL10及 CXCR3的表达与膀胱癌的发生发展及淋巴结转移可能存在相关性，阻断 CXCL10/CXCR3反应轴，可能会成为膀胱癌治疗的一个新靶点。%Objective To study the expression of CXCL10 and its receptor CXCR3 expression in bladder neoplasm and ex-plore their clinical significance.Methods Totally 80 patients with bladder neoplasm and 33 healthy control were recruited in this study.The serum level of CXCL10 was determined by ELISA and CXCR3 mRNA in peripheral blood mononuclear cell was meas-ured by RT-PCR.The relationship of serum CXCL10 and CXCR3 levels with clinical parameter were analyzed.Results The serum CXCL10 and CXCR3 levels in patients of bladder neoplasm were significantly higher than the control group(P >0.05).The serum CXCL10 and CXCR3 levels was significantly correlated with lymphatic metastasis (P <0.05).Conclusion High expression of CX-CL10 and CXCR3 may relate to bladder cancer and possibly correlate with lymphatic metastasis.
