胰腺癌中GLI1、PTCH1 mRNA的表达及其与临床指标相关性分析

目的 检测胰腺癌组织中GLI1、PTCH1 mRNA的表达情况,探讨其临床意义.方法 应用实时荧光定量PCR方法检测35例胰腺癌组织及27例癌旁正常胰腺组织中GLI1、PTCH1 mRNA的表达,并分析它们与相关临床指标的关系.结果 胰腺癌组织GLI1 mRNA相对表达量为1.12～3.65,中位数为1.19;PTCH1 mRNA相对表达量为1.82～4.36,中位数为2.36.癌旁正常胰腺组织的GLI1 mRNA相对表达量为0.23～2.76,中位数为0.87;PTCH1 mRNA相对表达量为1.11～2.17,中位数为0.58.癌组织GLI1、PTCH1 mRNA的表达量均显著高于癌旁正常胰腺组织(P＜0.05),且GLI1 mRNA与PTCH1 mRNA的表达水平呈正相关(r=0.532,P＜0.05);GLI1 mRNA的表达水平与胰腺癌的分化程度及淋巴结转移相关(P＜0.05).结论 GLI1、PFCH1基因参与胰腺癌的发生;GLI1的表达与胰腺癌的侵袭及淋巴结转移有关.

Expression of GLI1 and PTCH1 mRNA and yts correlation with clinical parameters in pancreatic cancer

Objective To investigate the expression of GLI1 and PTCH1 mRNA in pancreatic cancer and study its clinical significance. Methods Real-time fluorescence quantitative PCR (RFQ-PCR) was used to detect the expression of GLI1 and PTCH1 mRNA in 35 samples of pancreatic cancer tissues and 27 samples of adjacent normal pancreatic tissues, and the correlation of GLI1 and PTCH1 mRNA expression with clinical parameters was investigated. Results The relative expression of GLI1 mRNA in pancreatic cancer tissues was 1.12 ～ 3. 65 ( median 1.19), the relative expression of TCH1 mRNA was 1.82 ～ 4.36 ( median 2.36 ). The relative expression of GLI1 mRNA in adjacent normal pancreatic tissues was 0.23 ～ 2.76 ( median 0.87 ), the relative expression of PTCH1 mRNA was 1.11 ～ 2. 17 (median 0.58). Both the expression of GLI1 and PTCH1 mRNA in pancreatic cancer tissues were significantly higher than those in normal pancreatic tissues (P<0.05), and a positive correlation was found between GLIl and PTCH1 mRNA expression levels (P <0.05 ). The expression of GLI1 mRNA was significantly correlated with the differentiation degree and lymph node metastasis of pancreatic cancer (P < 0. 05). Conclusions GLI1 and PTCH1 may be involved in pancreatic carcinogenesis, and GLI1 may be related to invasion and lymph node metastasis of pancreatic cancer.
