Abstract:
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.
