Description

快速筛选小鼠mmu-miR-25-3p与启动子结合靶点的方法
技术领域
本发明属于生物医学技术领域,具体设涉及一种快速筛选小鼠mmu-miR-25-3p与启动子结合靶点的方法。
背景技术
microRNAs(miRNAs)是一种小的,类似于siRNA的分子,由高等真核生物基因组编码,miRNA通过和靶基因mRNA碱基配对引导沉默复合体(RISC)降解mRNA或阻碍其翻译。miRNAs在物种进化中相当保守,在植物、动物和真菌中发现的miRNAs只在特定的组织和发育阶段表达,miRNA组织特异性和时序性,决定组织和细胞的功能特异性,表明miRNA在细胞生长和发育过程的调节过程中起多种作用。目前对于microRNAs的研究越来越被重视,其对于很多疾病的诊断有着重大价值。
启动子是一段位于结构基因5'端上游区的DNA序列,能活化RNA聚合酶,使之与模板DNA准确地相结合并具有转录起始的特异性。因为基因的特异性,转录取决于酶与启动子能否有效地形成二元复合物,故RNA聚合酶如何有效地找到启动子并与之相结合是转录起始过程中首先要解决的问题。有实验表明,对许多启动子来说,RNA聚合酶与之相结合的速率至少比布朗运动中的随机碰撞高100倍。
因此为了更好更方便的研究microRNAs,我们需要对其与启动子的结合靶点进行有效筛选,以供后续实用。
