运动相关蛋白Fascin在胰腺癌的表达及其临床意义

目的 探讨运动相关蛋白Fascin在胰腺癌的表达及其与临床病理特征的关系.方法 采用RT-PCR法检测SW1990、Patu8988、BxPC3、CfPAC1 4株胰腺癌细胞株Fascin mRNA表达;采用免疫组化方法 检测54例胰腺癌及42例相应癌旁胰腺组织Fascin蛋白表达.结果 胰腺癌细胞株SW1990、Patu8988、CfPAC1有Fascin mRNA表达,BxPC3无表达;54例胰腺癌组织Fascin蛋白表达阳性35例,占64.8%,42例癌旁胰腺组织中均无阳性表达.Fascin蛋白表达与肿瘤分化程度(P<0.01)和淋巴转移(P<0.05)呈显著正相关,但与肿瘤大小及远处转移无相关性(P>0.05).结论 Fascin蛋白在胰腺癌组织中有较高的阳性表达率,检测其表达有助于胰腺癌的诊断,并有助于判断胰腺癌恶性程度.

The expression and significance of Fascin mRNA and its protein in pancreatic carcinoma cell line and pancreatic cancer tissues

Objective To investigate the expression of Fascin mRNA and its protein in human pancreatic carcinoma cell line and pancreatic cancer tissues and to explore the relationship between the expression of Fascin protein and the clinicopathologic parameters. Methods The expression of Fascin mRNA in pancreatic cancer cell lines (SW1990, Patu8988, BxPC3, cfPAC1) were measured by RT-PCR and the expression of Fascin protein in 54 samples of pancreatic career tissues and 42 adjacent normal pancreatic tissues was detected by immunohistochemical method. Results The expression of Fascin mRNA was confirmed in 3 of 4 pancreatic cancer cell lines (SW1990, Patu8988, cfPAC1), but not in the cell line of BxPC3; the rate of positive expression of Fascin protein in pancreatic cancer tissues was 64.81% (35/54) and there was no positive expression in adjacent normal pancreas tissues; the expression of Fascin protein correlated with the differentiation degree (P < 0.01) and with the lymphatic metastasis of the carcinoma (P <0.05), but not with the size and distant metastasis of the carcinoma (P > 0. 05). Conclusions Fascin protein was highly positively expressed in pancreatic cancer tissues, and the expression of Fascin protein may help diagnose pancreatic, carcinoma and predict the malignant degree.
