HGF、c-Met和VEGF-C在宫颈癌中的表达

Expression of HGF,c-Met and VEGF-C in Cervical Carcinoma

  • 摘要: 目的检测宫颈癌组织中HGF及其受体原癌基因c-Met和VEGF-C的分子表达水平及三者间的关系。方法 采用实时荧光定量RT-PCR(Real Time fluorescence Quantitative PCR,FQ RT-PCR)技术相对定量检测43 例宫颈浸润癌,30例CIN Ⅲ和27例正常宫颈组织标本中HGF mRNA、c-Met mRNA和VEGF-C mRNA的表达水平。结果HGF mRNA、c-Met mRNA和VEGF-C mRNA在正常宫颈、CIN Ⅲ和宫颈浸润癌组织中的表达水平依次升高,差异有统计学意义(P<0.05)。宫颈癌组织中三者表达水平与肿瘤临床分期、肿瘤直径大小、浸润深度、淋巴结转移有关(P均<0.05)。 HGF mRNA与c-Met mRNA和VEGF-C mRNA表达相关(P<0.01)。结论HGF、c-Met和VEGF-C在宫颈癌发生、发展、转移中发挥重要作用,它们参与了宫颈癌新生血管和淋巴管的形成,对宫颈癌的诊断、治疗及预后有指导意义。

     

    Abstract: ObjectiveTo investigate the expression level of hepatocyte growth factor(HGF) and its receptor, the proto-oncogene c-Met, and vascular endothelial growth factor-C(VEGF-C) in cervical carcinoma. Methods The mRNA levels of HGF,c-Met and VEGF-C were detected by Real Time fluorescence Quantitative PCR(FQ RT-PCR) method in 43 cervical carcinoma tissues,30 cervical intraepithelial neoplasm Ⅲ(CINⅢ)tissues and 27 normal cervical,respectively. Results The positive expression of HGF mRNA,c-Met mRNA and VEGF-C mRNA increased remarkably from normal tissue to CINⅢ and then to cervical carcinoma (P<0.05).In cervical carcinoma, the expression of these three genes was positive correlated with the clinical stage,tumor size,the invasion of deep muscular layer and the lymph node metastasis (P<0.05).These three genes were significant positive correlation (P<0.01). Conclusion Over expression of HGF, c-Met and VEGF-C together may participate in the invasion and metastasis of cervical carcinoma.To investigate them together would be facilitated to the treatment and prognosis of cervical carcinoma.
