摘要: 目的 利用小分子肽ATWLPPR(A7R)对人舌癌细胞SCC9进行靶向拮抗其神经纤毛蛋白1(Neuropilin-1,NRP-1),研究其对人舌癌细胞SCC9迁移、分化的影响。方法 通过免疫印迹实验(Western Blot,WB)检测NRP-1蛋白在舌癌组织及人舌癌细胞SCC9中的表达情况,利用划痕实验及Transwell检测小分子肽A7R对SCC9细胞迁移的影响,以及利用实时定量荧光PCR(Real-Time RT-PCR)检测相关上皮、间充质标记蛋白的mRNA表达变化,研究小分子肽A7R对SCC9细胞分化的影响。结果 NRP-1在SCC9中呈高表达,A7R拮抗后SCC9细胞迁移能力明显下降,同时SCC9细胞上皮相关标记蛋白(epithelial cadherin,E-cad、β-catenin,β-cate)mRNA表达水平增高,而间充质相关标记蛋白(snail、fibronectin,FN、α-smooth muscle actin、α-SMA)mRNA表达水平下降。结论 外源性拮抗SCC9细胞NRP-1可抑制其迁移能力并影响其细胞分化。

Abstract: Objective: To investigate the effect exogenous inhibition of Neuropilin-1(NRP-1) on the migration and the differentiation of the human tongue squamous carcinoma cell line SCC9. Methods: Western blot were performed to examine the expression of NRP-1 in cell line SCC9 and the human tongue squamous carcinoma cell cancer tissue. Besides, scratch test and transwell assay were employed to show the influence of exogenous inhibition of Neuropilin-1(NRP-1)on the migration of the SCC9 cells. And Real-time RT PCR were used to detect the expression of differentiation markers in the SCC9 cells exogenously inhibited of NRP-1. Results: NRP-1 express at high level in the SCC9 cells, and exogenous inhibition of NRP-1 depressed the migration of SCC9 cells. Real-time RT PCR showd the expression of epithelial cadherin and β-catenin increased, while the expression of snail, fibronectin and α-smooth muscle actin decreased. Conclusions: Exogenous inhibition of NRP-1 depressed the migration and differentiation of SCC9 cells.
