Zhongguo shiyan zhenduanxue, 2019 心肌纤维化(MF)是心脏间质重塑,其以心脏间质成纤维细胞的增殖过度,胶原的沉积过度和分布异常为主要特征。微小RNA是一类内源的,非编码的单链RNA分子,其长度约为22个核苷酸,广泛存在于真核生物中,参与调控基因转录后的表达。目前,microRNA在心血管疾病领域中的研究增加,并且趋于成熟。诸多研究结果表明microRNA参与并调节了心肌纤维化的发生、进展过程及病理形成过程,有望指导疾病的预测,诊断和治疗。1心肌纤维化心肌纤维化是心脏间质发生重塑 ...

The Research and Exploration of JMJD2A Biological Function [PDF]
, 2014 JMJD2A又叫做KDM4A或者JHDM3A,是一种组蛋白去甲基化酶。它可以催化三甲基化/二甲基化状态的H3K9和H3K36去甲基化到不同的甲基化水平。研究表明JMJD2A在乳腺癌细胞、结肠癌细胞、鳞状细胞癌细胞中是一种原癌基因。另外，JMJD2A还可以作为转录因子的辅激活子或者辅抑制子的结合蛋白来在转录水平上调控基因的表达。JMJD2A自身的蛋白水平可以受到泛素-蛋白酶体途径调控且具有细胞周期依赖性。 本文中，我们发现了JMJD2A的一些新的生物学功能 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2021 目的基于癌症基因组图谱（TCGA）数据库食管鳞癌lncRNA差异表达，构建食管鳞癌预后风险模型。方法从TCGA肿瘤数据库下载食管鳞癌基因表达数据及临床信息，使用R 4.0.3软件提取差异表达lncRNA，进一步使用COX回归分析筛选模型lncRNA，并构建预后风险模型Riskscore；按照风险评分中位值将食管鳞癌患者分为低风险组和高风险组，进一步比较高低风险组生存预后；分析比较风险模型及其他临床特征对食管鳞癌生存预后的预测性能；分析风险评分与其他临床特征相关性；采用主成分分析（PCA）及基因富集分析 ...

Zhongguo shiyan zhenduanxue, 2019 在人类基因组中,编码蛋白质的序列仅占2%[1],绝大部分的DNA不具备编码功能,这些DNA转录后形成的产物即为非编码RNA(Noncoding RNA,ncRNA)。起初发现时,受研究条件的限制,ncRNA长期被认为是RNA聚合酶Ⅱ转录的副产物 ...
