Sci Rep:特定lncRNAs的基因多态性是否与系统性红斑狼疮的发生相关?

2017-11-12 MedSci MedSci原创

越来越多的研究表明长练非编码RNAs(lncRNAs)与多种自身免疫性疾病之间存在关联。为了探索系统性红斑狼疮(SLE)中的四种lncRNAs(GAS5,lnc-DC,linc0597和linc0949)表达水平和基因多态性,本研究采用两阶段研究设计。在第一阶段,纳入了85名SLE患者和71名健康对照,以研究lncRNAs的表达水平。然后,再次纳入1260名SLE患者和1231名健康对照者以检测第

越来越多的研究表明长练非编码RNAs(lncRNAs)与多种自身免疫性疾病之间存在关联。为了探索系统性红斑狼疮(SLE)中的四种lncRNAs(GAS5,lnc-DC,linc0597和linc0949)表达水平和基因多态性,本研究采用两阶段研究设计。

在第一阶段,纳入了85名SLE患者和71名健康对照,以研究lncRNAs的表达水平。然后,再次纳入1260名SLE患者和1231名健康对照者以检测第一阶段鉴定的差异表达的lncRNAs的单核苷酸多态性(SNPs)。

结果显示,LinC0597、lnc-DC和GAS5的表达水平在SLE患者中明显低于健康对照者(P <0.001,P <0.001,P = 0.003)。分析5种SNPs(rs10515177,rs2070107,rs2632516,rs2877877,rs2067079)与SLE风险的关联。结果显示这些基因多态性与SLE易感性无明显相关性(P> 0.010),而且研究人员发现任何基因型的5个SNPs及其lncRNAs的表达与SLE之间均无明显相关性(均P> 0.010)。

综上所述,该研究结果表明,SLE患者linc0597、lnc-DC和GAS5的表达水平下降,但其基因多态性与SLE的发生风险无关,且不影响其表达水平。
