ppGalNAcT2反义RNA对胃癌细胞SGC7901生物学特性的影响

目的:研究人胃癌细胞SGC7901中多肽N-乙酰氨基半乳糖转移酶2(pp-GalNAc-T2)基因表达与肿瘤转移相关基因MMP2,TGF-β1表达的相关性,以及对细胞增殖和形态生物学特性的影响。方法:用两个已构建好的反义表达载体转染胃癌细胞SGC7901,通过G418筛选,建立一系列旨在封闭胃癌细胞SGC7901ppGalNAc-T2基因表达的亚细胞克隆。通过共聚焦显微镜,RT-PCR检测反义封闭pp-GalNAc-T2基因RNA表达后,胃癌细胞SGC7901中TGF-β1,MMP2表达水平,细胞增殖以及形态的变化。结果:反义封闭pp-GalNAc-T2基因表达后,胃癌细胞SGC7901pp-GalNAc-T2的表达水平明显降低,细胞的形态发生改变,分裂增殖减慢。结果还显示,反义封闭pp-GalNAc-T2基因表达可使TGF-β1,MMP2基因在mRNA表达水平均增加,提示pp-GalNAc-T2基因表达可能对胃癌细胞SGC7901浸润转移产生影响。结论:pp-GalNAc-T2可能在肿瘤的增殖、浸润和转移中发挥作用。

中国南方四省区流行的HIV-1 CRF01_AE病毒株基因特征研究

Objective To analyze the genetic characteristics of HIV-1 CRF01_AE strains prevailing in. the four provinces of southern China. Methods Plasma samples were collected from the newly diagnosed HIV-1 individuals reported in 2006 in Guangdong, Guangxi, Jiangxi and Hunan province. The gag and env gene fragments were amplified from RNA template extracted from plasma using RT and nested PCR methods. CRF01_AE sequences were analyzed by phylogcnetie methods and characterized by calculating the genetic distance and Entropy analysis. Results Two main epidemic clusters were found to exist in the CRF01 AE strains from 210 HIV-1 CRF01 AE infected individuals collected in the 4 provinces, southern China. It was found that no international reference strain was closely correlated with cluster Ⅰ , which including 123 samples. The strains in cluster Ⅱ, consisting 57 cases of samples, were closely related with the strains identified in Vietnam. Genetic distance analysis of gag and env genes showed that the diversity of cluster Ⅰ was obviously less than that of cluster Ⅱ. Data on nucleotide polymorphism showed that nucleotides compositions of 42 sites in gag and 40 sites in env wer esignificantly different between the two clusters. When compared with cluster Ⅱ , the polymorphism decreased at 61 nucleotide sites but increased at 21 sites in cluster Ⅰ. Conclusion This was the first report describing that two main epidemic clusters were existed in CRF01_AE strains prevailing in the 4 provinces, Southern China. The vires in cluster Ⅰ was the dominant strain in this region, with shorter period of circulation and higher proportion seen in the HIV-infected population, which might belong to CRF01_AE strain with certain features facilitating the spread of the virus. The virus in cluster Ⅱ was highly homology with the CRF01_AE strains from Vietnam, and seemed to have had several events of epidemics in populations in border regions of China and Vietnam.
