通过蛋白质组学分析探究microRNA-21a-5p在小鼠脊髓损伤模型中的作用及相关信号通路
发布时间:2023-04-01 02:01
脊髓损伤(SCI)是脊柱损伤最严重的并发症,是一种严重的神经系统功能障碍性疾病,损伤后会导致损伤节段以下肢体发生严重的功能障碍,最典型的表现为损伤部位以下瘫痪,这不仅会给损伤患者本人带来严重的身心伤害,还会给家庭和社会带来沉重的经济、心理负担。随着现代社会经济的快速发展,尤其交通事故、工程建设和自然灾害等各类创伤的发病率上升,呈现致伤因子高能量、瞬间作用于人体造成多部位和多脏器损伤的特点,脊髓损伤发生率出现逐年增高的趋势,尽管国内外关于SCI的基础、临床研究众多,但如何对脊髓损伤进行有效的预防和治疗已经成为当今医学界的一大难题。microRNAs(miRs)是一类进化上非常保守,长度介于21~25nt的非编码RNA(non-coding RNA,ncRNA)单链小分子,它能够通过降解靶基因mRNA或者抑制其翻译过程,达到负向调控目的蛋白的作用。miRs在不同生物体内与靶标结合的方式不尽相同,而且通常可与多种蛋白相互作用。这种复杂的调节网络既可以通过一个miR来调控多个基因的表达,也可以联合几个miRs来精细调控某个基因的表达。miRs的这种特性决定了其可以同时调节多种靶蛋白,进而调控细...
