Description

circRNAs作为活动性肺结核病特异性标志物的应用
技术领域
本发明涉及分子生物学技术领域,尤其涉及一种制备活动性肺结核病特异性circRNAs的方法。
背景技术
结核病是一个重大的全球性公共卫生问题,严重威胁着人类健康。肺结核是结核病中最常见的临床类型。肺结核是一种由结核杆菌感染引起的慢性传染病。根据世界卫生组织(WHO)报道,2015年,全世界新发结核病数量约为1040万例,新发48万例耐多药结核病,有140万人死于结核病。中国发病人数居世界第二位。据估计,近5.5亿的结核感染人群,每年新发生肺结核患者100万例。死亡率2.32/10万。由于肺结核病主要通过空气传播,具有高发病率和高死亡率,因此对社会产生了相当大的负担。早发现、早诊断、早治疗,可控制肺结核病传播,是遏制肺结核病流行的最重要措施;但是活动性肺结核病的研究难点是缺乏特异的标志物。
环状RNA(circular RNAs,circRNAs)是一类新型非编码RNA,不具有 5' 末端帽子和 3' 末端 poly(A)尾巴、并以共价键形成环形结构的非编码 RNA 分子,与传统非编码不同,环状RNA分子为封闭环状结构,由于对核酸酶不敏感,因此比线性RNA更为稳定。circRNAs有组织特异性与时空特异性,不同组织之间的circRNAs表达量不同,同一组织或器官在不同生长阶段,其中的circRNAs表达量也会变化,circRNAs可从染色质重塑、转录调控及转录后加工等多种层面实现对基因表达的调控,其作用机制非常复杂,至今尚未完全清楚,比如已有许多研究证实了miRNAs参与调节TGFβ表达量和EMT过程,但参与此过程的circRNAs并不清楚。另外,一些在线网站比如starBase 2.0网站预测准确率低,比如现在已经比较明确的GAS5和miRNA21都预测不到,而且人血清中存在多达1000个circRNAs,还有一定的变化,导致circRNAs无法有效利用,同时circRNAs的检测和分析已成为其应用的关键问题,现有测序法操作复杂,费用贵,测序深度有限,效率较低,导致circRNAs 的检测变数较大;目前已有一些关于circRNAs作为癌症分子标志物的研究,但是仅是存在可能性,比如科学家发现结直肠癌患者大部分新的circRNAs表达上调,在胃癌中有的circRNAs表达下调;有研究者在EMT中发现,上百种circRNA的表达受TGF-β的影响,比如,DOCK1是一种鸟苷酸交换因子(GEF),可激活Rac以提高细胞活性,使用TGF-β诱导EMT过程后,上皮细胞中含量最为丰富的DOCK1 circRNA水平下降了30倍,而DOCK1 mRNA水平则上升了2倍,提示这一circRNA的功能之一可能是引起上皮细胞中mRNA的下调,然而,鉴于上皮细胞中含有大量的DOCK1 circRNA,其很可能还有其他方面的功能,总而言之,circRNA在EMT中的确切作用及相关机制仍有待进一步明确。虽然circRNA具有保守性和稳定性,但目前检测和定性circRNA的方法仍有局限性,不同的生物信息学方法或测序数据造成circRNA的识别出现偏倚;因此针对活动性肺结核病,研发合适的特异性circRNAs作为标志物在调控基因转录、作为疾病诊断标志物等方面具有重要的研究和临床意义。

本发明所要解决的技术问题是提供一种作为针对活动性肺结核病特异性标志物的circRNAs及其应用。本发明首次公开了两个circRNAs作为活动性肺结核病特异性标志物,表达谱的变化具有组织和细胞特异性,同时具有很高的稳定性;利用临床上比较容易直接获得的全血标本,结合设计的引物对进行RT-qPCR验证circRNAs的差异表达,具有快速、简单、省时、检测灵敏度高,样品消耗少的优点,是非常适合的利用差异表达的circRNAs诊断活动性肺结核病的方法。

本发明中,通过检测人体全血样本中的circRNA-00074或者circRNA-14623的表达情况即可诊断活动性肺结核病,与现有临床检测手段结果吻合。
本发明公开了活动性肺结核病诊断试剂盒,该试剂盒含有能够对circRNAs的表达量进行定量的试剂,所述circRNAs为circRNA-00074或者circRNA-14623;优选的,所述能够对circRNAs的表达量进行定量的试剂包括RT-qPCR引物对;所述RT-qPCR引物对的序列为SEQ ID NO:1、SEQ ID NO:2或者SEQ ID NO:3、SEQ ID NO:4。
