小分子RNA,特别是microRNA,在心脏发育和先天性心脏病中发挥着重要作用。几项研究表明,在法洛四联症(TOF)患者的心室组织中存在失调的miRNA。在本研究中,我们进行了高通量测序,以获得来自10名年龄匹配的TOF患者的心脏右心室样本中小RNA转录组的总体概况。这些样品显示了miRNA和线粒体相关RNA的优势组成。通过sRNA聚类分析和差异基因表达分析,发现TOF患者sRNA表达存在明显的性别差异。miR-1/miR-133被认为是心脏发育所必需的,是TOF心脏中sRNA表达在性别间差异最大的原因。
Small RNAs, especially the microRNAs, have been revealed to play great roles in heart development and congenital heart defects. Several studies have shown dysregulated miRNAs in ventricular tissues of Tetralogy of Fallot (TOF) patients. In the present study, we conducted high throughput sequencing to obtain the global profiling of small RNA transcriptome in heart right ventricular samples from 10 age -matched TOF patients. These samples showed dominant composition of miRNA and mitochondrial associated RNAs. By sRNA cluster identification and differential gene expression analysis, significant sexual difference was discovered for sRNA expression in TOF patients. miR-1/miR-133, which have been identified as essential for cardiac development, account for the most variance of sRNA expression between sexes in TOF hearts.
