文题释义:

单核苷酸多态性:指在基因组水平上由单个核苷酸变异所引起的DNA序列多态性,它是人类可遗传变异中最常见的一种,占所有已知多态性的90%以上。单核苷酸多态性在人类基因组中广泛存在,所表现的多态性只涉及到单个碱基的变异,这种变异可由单个碱基的转换或颠换所引起,也可由碱基的插入或缺失所致。

信号传导和转录活化因子3信号通路:与肿瘤、自身免疫性疾病等密切相关,但研究多集中于功能方面,文章从基因的层面分析了该转录因子在类风湿关节炎中的作用,通过基质辅助激光解吸电离飞行时间质谱法对信号传导和转录活化因子3基因的多态性位点进行基因分型,发现信号传导和转录活化因子3有可能是中国汉族人类风湿关节炎的易感基因。

 

背景:信号传导和转录活化因子3(signal transducer and activator of transcription-3,STAT3)是一条重要的细胞因子信号传导通路,在炎症性疾病中发挥重要作用。STAT3基因的多态性是否与中国汉族人群类风湿关节炎相关还不明确。

目的:探讨STAT3基因单核苷酸多态性与中国汉族人群类风湿关节炎易感性之间的关系。
方法:在HapMap中国汉族人群数据库中,选择STAT3基因标签单核甘酸多态性。以228例类风湿关节炎患者和228例正常对照为研究对象,使用基质辅助激光解吸电离飞行时间质谱法对STAT3基因4个标签单核甘酸多态性(rs12601982、rs2293152、rs8078731和rs9912773)进行基因分型。
结果与结论:类风湿关节炎组和对照组rs9912773的GG基因型分布频率分别为18.9%、10.5%,CC基因型分别为35.5%、38.2%,CG基因型分别为45.6%和51.3%,两组间基因型频率分布差异有显著性意义(P < 0.05)。提示中国汉族人群STAT3基因rs9912773位点多态性可能与类风湿关节炎易感性相关。

Abstract:

BACKGROUND: Signal transducer and activator of transcription 3 (STAT3) is an important cytokine signaling pathway, which plays an important role in inflammatory diseases. However, it is unclear whether gene polymorphism of STAT3 is associated with rheumatoid arthritis in the Chinese Han population.
OBJECTIVE: To explore the association of gene polymorphism of STAT3 with rheumatoid arthritis in the Chinese Han population.
METHODS: Four tag-single-nucleotide polymorphisms (tag-SNPs) in STAT3 were selected from the Chinese Han population of HapMap database. The study was performed with 228 rheumatoid arthritis cases and 228 normal controls. Four tag-SNPs (rs12601982, rs2293152, rs8078731 and rs9912773) were examined by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry.
RESULTS AND CONCLUSION: The frequency of GG genotype at rs9912773 was 18.9% and 10.5% respectively in rheumatoid arthritis and control groups, and there was a significant difference between the two groups (P < 0.05). These results indicate the possible association between the STAT3 gene polymorphism at rs9912773 and the susceptibility of rheumatoid arthritis in the Chinese Han population.
