目的:探讨肿瘤微环境中神经元对胶质瘤细胞迁移能力的影响。方法:分离培养胚胎18 d(E18)大鼠神经元,利用表达靶向神经连接蛋白3(NLGN3)分子shRNA的重组慢病毒(Lv-NLGN3-shRNA)感染神经元,real time RT-PCR和酶联免疫吸附试验(ELISA)检测...目的:探讨肿瘤微环境中神经元对胶质瘤细胞迁移能力的影响。方法:分离培养胚胎18 d(E18)大鼠神经元,利用表达靶向神经连接蛋白3(NLGN3)分子shRNA的重组慢病毒(Lv-NLGN3-shRNA)感染神经元,real time RT-PCR和酶联免疫吸附试验(ELISA)检测NLGN3的表达,收集神经元培养上清与胶质瘤细胞系U251细胞共培养,Transwell实验检测U251细胞迁移能力,Western Blot方法检测U251细胞中哺乳动物雷帕霉素靶蛋白(mTOR)和基质金属蛋白酶-9(MMP-9)的表达。结果:Lv-NLGN3-shRNA重组慢病毒感染能够降低大鼠原代神经元中NLGN3 mRNA和蛋白的的表达,神经元培养上清与U251细胞共培养可以增加后者的迁移能力并上调mTOR和MMP-9的表达。然而,NLGN3表达被Lv-NLGN3-shRNA抑制后,培养上清对U251细胞促迁移能力下降,同时mTOR和MMP-9表达降低。结论:大鼠原代神经元可以通过NLGN3/mTOR/MMP-9信号通路增强U251细胞的迁移能力,这一途径可能是胶质瘤细胞转移的机制之一。展开更多

Single nucleotide polymorphisms（SNPs） of MMP-9 and p53 genes are associated with the risk and progression of many cancers. In this study, we evaluated the association of the R279Q polymorphism of MMP-9 or the A1/A2 polymorphism of p53 gcne with the risk of no-small-cell lung cancer（NSCLC） in Han population of Northeast China. We examined the frequency of SNPs in the two kinds of genes of 50 patients with NSCLC and 50 cancer-free controls frequency-matched by age and sex. Polymerase chain reaction-restriction fragment length polymorphism（PCR-RFLP） technique was used to determine the genotypes. The results indicate that the 279RR genotype in MMP-9 gene and the A1/A2 genotype in p53 gene show a significantly increased risk of NSCLC. Therefore, the MMP-9 279RR and p53 A1/A2 genotypes may be used as markers for susceptibility to NSCLC in Han population of Northeast China.展开更多
