microRNA-218通过靶向HOXA10抑制肝癌细胞的实验研究
Zhongguo shiyan zhenduanxue, 2019 微小RNA(microRNA,miRNAs)是一类长约22个核苷酸的单链非编码RNA,通过与靶mRNAs完全或不完全互补配对,导致靶基因降解或抑制其翻译,从而在基因的表达调控中发挥着重要作用。研究表明microRNAs参与了肝癌的发生、发展和侵袭转移的全过程[1,2]但是有关miR-218在肝癌(HCC)的生物学功能仍然未知 ...

Zhongguo shiyan zhenduanxue, 2020 胶质瘤(glioma)是起源于脑部或脊髓的神经系统肿瘤,根据组织细胞形态学特征可分为不同的亚型。胶质瘤组织病理学分类仍存在较大异质性,同一病理类型患者其分子学改变、病程演进、治疗反应等仍不尽相同[1]。因而,深入研究胶质瘤的分子病理机制是近年的研究热点之一。微小RNA(micro RNAs,miRNAs)为长度19-22个核苷酸组成的非编码RNA,通过与靶基因信使RNA结合,进而调控基因的转录后表达 ...

尿外泌体非编码RNA在糖尿病肾病发病机制及诊断中的最新研究进展
Zhongguo shiyan zhenduanxue糖尿病肾病（diabetic kidney disease,DKD）如今占所有导致终末期肾病（end-stage renal disease ESRD）原发病的近50%[1]。目前糖尿病肾病的诊断及分期主要依靠尿微量白蛋白的检测，其缺点是敏感性和特异性相对较低，而肾穿刺活检术则操作风险较高，尚缺少采集程序无创性的理想检测标志物。外泌体是直径范围40～160nm被脂质双层膜包裹的囊泡，广泛分布于血液、尿液等体液中。尿液中的外泌体是一种易采集的非侵入性生物标志物 ...

非小细胞肺癌术前循环miR-125和miR-205对预后判断价值比较
Zhongguo shiyan zhenduanxue, 2019 miRNA（小RNA）是长度约为20个核苷酸左右的一类内源保守的非编码RNA分子,在体内通过调控mRNA的翻译发挥生物学作用[1]。miRNA除了存在于组织细胞中,最近报道其在血液中也能稳定存在,并且循环miRNA已被证实在不同的病理条件下存在差异表达,因此其可作为疾病的生物标志分子[2,3 ...

Transcriptional regulation of Dicer by FoxO3 [PDF]
, 2017 MicroRNAs（miRNAs）是一类16-29nt长的分布极其广泛的小的非编码RNA，作为RNA干扰沉默复合体的一部分，其最主要的作用是特异性靶向结合具有同源序列的mRNA进而负向调控基因的表达，参与调控了几乎所有的信号通路，对于维持机体正常的生物学功能至关重要。研究表明miRNA的异常突变或者异位表达常常伴随着疾病以及癌症。而作为RNA干扰沉默复合体的核心组分，Dicer一方面通过切割外源dsRNA为siRNA介导RNAi抵抗外来核酸的影响，还能通过将内源序列加工成miRNA调节内源基因的表达 ...
