技术领域
本发明涉及生物技术领域,具体涉及一种抑制ATF6α基因的siRNA分子及其应用。
背景技术
类风湿性关节炎(RA)是一种慢性全身炎症性疾病,是最常见的系统性自身免疫性疾病。RA的发病机制十分复杂,与遗传、免疫等等多种因素都有关系,但目前尚未能阐明。RA的发生与体内炎性反应的持续存在密切相关,持续的炎性反应会激活ER应激,因此分泌炎性因子的Th17细胞以及ER应激相关蛋白的表达受到广泛的关注。同时在之前的研究中发现巨噬细胞迁移抑制因子(MIF)在自身免疫性疾病中发挥着重要作用的细胞因子,能促进炎性因子的分泌。
结合上述,研究它们在RA发展过程中起到的作用后,之前结果显示在RA患者的CD4+T细胞中ER应激被激活,Th17比例升高,MIF和IL-17A的表达上调且MIF与ATF6存在相互作用,Th17细胞分化的相关蛋白表达上调,表明MIF可通过增强被激活的ATF6通路诱导Th17细胞的分化。
因此,有必要开发一种抑制ATF6α基因的siRNA分子及其应用,从而有效抑制ATF6α基因的表达,同时降低Th17细胞分化基因的表达,下调Th17细胞的比例,为治疗RA提供一个全新的靶点。
发明内容
本发明旨在至少解决上述现有技术中存在的技术问题之一。为此,本发明提出一种抑制ATF6α基因的siRNA分子及其应用,从而有效抑制ATF6α基因的表达,同时降低Th17细胞分化基因的表达,下调Th17细胞的比例,为治疗RA提供一个全新的靶点。

具体的,所述siRNA分子为如下(1)至(3)中的任意一种;
(1)SEQ ID NO:1所示的RNA单链和SEQ ID NO:2所示的RNA单链互补而成的siRNA分子;
(2)SEQ ID NO:3所示的RNA单链和SEQ ID NO:4所示的RNA单链互补而成的siRNA分子;
(3)SEQ ID NO:5所示的RNA单链和SEQ ID NO:6所示的RNA单链互补而成的siRNA分子。
本发明的第二方面提供一种能产生第一方面siRNA分子的DNA分子。
本发明的第三方面提供一种试剂盒。
具体的,所述试剂盒包含第一方面的siRNA分子或第二方面的DNA分子。
本发明的第四方面提供一种siRNA分子在制备预防和/或治疗炎症药物中的应用。
优选的,所述炎症包括关节炎症。
进一步优选的,所述关节炎症包括类风湿性关节炎。
本发明的第五方面提供一种siRNA分子在制备保护软骨和/或滑膜药物中的应用。
本发明的第六方面提供一种siRNA分子在制备抑制ATF6α基因表达药物中的应用。
本发明的第七方面提供一种siRNA分子在制备抑制Th17细胞分化基因表达药物中的应用。
本发明的第八方面提供一种siRNA分子在制备降低巨噬细胞迁移抑制因子诱导的Th17细胞比例药物中的应用。
相对于现有技术,本发明的有益效果如下:
本发明的siRNA分子可抑制ATF6α基因的表达,抑制了ATF6α通路,同时抑制了Th17细胞分化基因的表达,从而能降低Th17细胞的比例,抑制了RA患者的Th17细胞的分化,进而可在制备预防和/或治疗类风湿性关节炎药物中应用,为治疗RA提供一个全新的靶点。

采集实施例4RA组PBMC后,其中一组用实施例1siRNA分子转染PBMC,同时加入rhMIF刺激3d,进行流式实验。另一组不使用实施例1siRNA分子转染PBMC,只加入rhMIF刺激3d,进行流式实验。siRNA分子转染PBMC的步骤同实施例9。
由图6可知,从流式结果及统计可知,实施例1siRNA分子能降低MIF诱导的Th17细胞比例,即本发明siRNA分子可抑制RA患者的Th17细胞的分化。
综上所述,本发明结果显示,本发明制得的siRNA分子可抑制ATF6α基因的表达,抑制了ATF6α通路,同时抑制了Th17细胞分化基因的表达,从而能降低Th17细胞的比例,抑制了RA患者的Th17细胞的分化,进而可在制备预防和/或治疗类风湿性关节炎药物中应用。
以上详细描述了本发明的较佳具体实施例。应当理解,本领域的普通技术人员无需创造性劳动就可以根据本发明的构思作出诸多修改和变化。因此,凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验所作的任何修改、等同替换、改进等得到的技术方案,皆应在由权利要求书所确定的保护范围内。
