Sci Rep:研究表明lncRNAs或可有助于肌炎的治疗

2017-09-04 MedSci MedSci原创

肌炎的特征是肌肉发炎和无力。虽然一般认为肌炎是由全身自身免疫反应所引发的,但是越来越多的证据表明,肌肉的内在变化也可能参与了肌炎的发病机制。长链非编码RNAs(lncRNAs)是一个新的家庭基因,参与调节基因的转录和翻译。为了确定lncRNAs的潜在作用,研究人员们采用新一代测序以探究肌炎及抗JO1相关肌炎(Jo-1)组织中转录组的表达差异。结果显示,Jo-1和IBM患者肌肉组织中分别有1287个

肌炎的特征是肌肉发炎和无力。虽然一般认为肌炎是由全身自身免疫反应所引发的,但是越来越多的证据表明,肌肉的内在变化也可能参与了肌炎的发病机制。长链非编码RNAs(lncRNAs)是一个新的家庭基因,参与调节基因的转录和翻译。

为了确定lncRNAs的潜在作用,研究人员们采用新一代测序以探究肌炎及抗JO1相关肌炎(Jo-1)组织中转录组的表达差异。结果显示,Jo-1和IBM患者肌肉组织中分别有1287个mRNAs和1068 mRNAs表达差异。通路分析表明,Jo-1和IBM最典型的通路均存在氧化磷酸化和线粒体功能障碍。

研究人员在肌肉活检组织中确定了731个已知和325个未知的新的lncRNAs。与对照组相比,IBM和Jo-1肌炎组织中分别有55个和46个lncRNAs表达存在差异。其中,16个lncRNAs在IBM和Jo-1肌炎组织中均差异表达,包括H19、lncmyod和MALAT1表达上调。

鉴于已知这些lncRNAs参与了调节肌细胞的增殖和分化,研究人员推测lncRNA或可有助于改变Jo-1和IBM肌炎的表型。

Onco Targets Ther:研究揭示与乳头状肾细胞癌预后相关的分子机制

乳头状肾细胞癌(PRCC)是肾细胞癌的第二个常见的亚型,其治疗和预后缺乏有效的治疗靶点和分子标志物。越来越多的研究关注长链非编码RNAs(lncRNAs)——可以作为竞争性内源性RNA(ceRNA)来竞争microRNAs(miRNAs),在人类肿瘤发生的中的作用。因此,为阐明lncRNA在PRCC中介导ceRNA网络的作用,研究人员全面整合了来自The Cancer Genome Atlas数据

Sci Rep:新的研究揭示脂肪细胞分化的分子机制

脂肪细胞在调节全身能量平衡中的起着重要作用,且与肥胖有着密切的关联。既往许多研究都强调,microRNA在脂肪细胞分化过程中的相关性,但是关于长非编码RNAs(lncRNAs)在脂肪细胞分化过程中的作用仍是未知。本研究中,研究人员确定了lncRNA MIR31HG与脂肪细胞的相关性。体外和体内研究结果表明,敲除MIR31HG可抑制脂肪细胞的分化,而过表达MIR31HG可促进脂肪细胞的分化。此外,抑

Nature:“长的非编码RNAs”在去势抵抗性前列腺癌中上调

几个“长的非编码RNAs”(lncRNAs) 已知在前列腺癌中过度表达。Michael Rosenfeld及同事研究了这些“长的非编码RNAs”中的两个的机制功能和生物功能,它们分别是PRNCR1 和 PCGEM1。二者都被发现依赖于特定的翻译后修饰与雄性激素受体(AR)发生相互作用,增强与AR结合在一起的增强子向目标基因启动子的成环作用(looping),导致基因表达增强。它们还增强前列腺癌细胞
