摘要
目的探讨Neuropilin-1在胰腺导管癌组织及MIAPaCa-Ⅱ胰腺癌细胞系中的袁达及意义。方法运用免疫组化和RT—PCR法分别检测正常胰腺组织、癌旁组织、胰腺癌组织及MIAPaCa-Ⅱ细胞系中Neuropilin-1蛋白及mRNA表达水平。结果蛋白水平可见正常胰腺组织无表达,癌旁组织轻度表达,而胰腺癌组织及MIAPaCa-Ⅱ胰腺癌细胞中高水平表达。神经组织也可表达Neuropilin-1。mRNA水平见正常胰腺组织微量表达,癌旁组织中度表达,而胰腺癌组织及MIAPaCa-Ⅱ胰腺癌细胞中高水平表达。结论Neuropilin-1可能参与了胰腺癌的发生发展,在胰腺癌神经转移中可能起着重要作用。
Objective To investigate the expression of Neuropilin-1 in human pancreatic ductal adenocarcinoma (PDAC) specimens and cell lines. Methods Expression and distribution of Neuropilin-1 were detected in operation tissue specimens of human pancreatic ductal adenocarcinoma with HE, immunohistochemistry and RT-PCR. Results Immunohistochemical analysis revealed that Neuropilin-1 were expressed in human pancreatic adenocarcinoma specimens, precancerous tissue and MIA PaCa-Ⅱ cell lines, but was absent in normal pancreatic tissue, mRNA of Neuropilin-1 could also be detected the in human pancreatic adenocarcinoma specimens, precancerous tissue and MIA PaCa- Ⅱ cell Lines, while could not be detected in normal pancreatic tissue. Neuropilin-1 expression in pancreatic adenocarcinoma were higher than that in normal pancreas, and the differences were significant( P 〈 0. 01 ). Conclusions Neuropilin-1 might play an potential role in carcinogenesis for pancreatic cancer. Neuropilin-1 may be relevant to perineural invasion of pancreatic carcinoma by some signal transduction.
