PLoS One:研究进一步揭示LncRNA参与心脏修复的机制

最新研究显示,使用干细胞和心脏祖细胞(CPCs)移植以治疗心血管疾病(CVD)促进心脏恢复具有巨大的潜力。然而,对控制这些细胞发育的分子机制尚未完全了解,且这对于优化其在这种治疗中的使用来说至关重要。

最近长链非编码(lnc)RNA已经成为参与各种关键生物学过程(包括发育、体内平衡和疾病)的关键调节分子。因此,越来越多的研究表明,他们也在CPC发展中发挥关键的调节作用,尽管在这个过程中所涉及的lncRNA表达谱和特定的lncRNA仍存在待解决的许多问题。

为了解决这些问题,研究人员使用两个小鼠CPC群体Nkx2-5-EmGFP和体外细胞进行整个转录组测序,以表征其lncRNA谱,并识别新的CPC调节因子。测序结果显示,两组CPC组织和细胞中与心脏分化相关的一组先前鉴定的lncRNA基因均表达上调。另外,相对于未分化的ES细胞,两个CPC群体中总共富集了1,678个差异表达的和尚未确定的假定的lncRNA。

本研究旨在调查长链非编码RNA PEG10(lncRNA PEG10)过表达对下咽鳞状细胞癌(HSCC)细胞的增殖、侵袭和转移的影响。采用定量逆转录聚合酶链反应定量检测HSCC肿瘤组织样本、癌旁组织样本和HSCC FaDu细胞系中的lncRNA PEG10的表达水平。分别使用细胞增殖试验、Transwell侵袭试验和伤口愈合试验评价lncRNA PEG10对体外FaDu细胞的影响。结果显示,在56

World J Surg Oncol:研究发现结直肠癌新的治疗和预后指标

结直肠癌(CRC)是最常见的恶性肿瘤之一,而目前关于结直肠癌发生发展的分子机制尚不清楚。越来越多的证据表明,长链非编码RNAs(lncRNAs)在肿瘤的发生、发展及转移中发挥了关键作用。因此,本研究旨在探究CRC进展过程中lncRNAs的作用。在这项研究中,研究人员使用GSE64857数据库确定CRC中异常表达的lncRNA和mRNA。GO和KEGG通路分析来探究CRC中这些lncRNAs和 mR

Sci Rep:研究揭示矽肺的发病机制

矽肺是一种慢性、进行性且不可治愈的肺纤维化疾病,目前其发病机制和分子机制尚未完全了解。既往研究表明miRNAs参与了矽肺病的发病机制。本实验既往关于miRNA的芯片研究表明,二氧化硅诱导的肺纤维化小鼠肺组织中miR-503的表达水平下调。本实验中,研究人员验证了暴露于二氧化硅的纤维化小鼠肺组织,人支气管上皮细胞(HBE)和人肺腺癌A549细胞中miR-503的表达水平降低。此外,miR-503过表
