As a well-known transcription factor, Homeobox A10 (HOXA10) regulates a large number of downstream target genes, leading to the proper function development of endometrium for embryo implantation. The change of HOXA10 gene expression level can alter the expressions of many other genes, including coding and noncoding transcripts. In our study, mRNA and LncRNA expression profiles screening was performed by microarray when the HOXA10 gene expression level increased in Ishikawa cells. A total of 907 mRNAs and 1,026 LncRNAs were identified as differentially expressed transcripts (Fold Change ≥2, P-value <0.05, and Q-value <0.05) between HOXA10 overexpressed and control Ishikawa cells. Further analysis identified that these mRNAs participated in various biological processes, such as blood vessel development, cell adhesion, cell cycle, etc. Also, 14 enhancer-like LncRNAs and 108 LincRNAs with their nearby mRNAs were identified as coregulated transcripts. Our results showed that the mRNA and LncRNA expression profiles differed significantly between the two groups and provided useful information for further studying the molecular mechanisms of HOXA10 in endometrium.
作为一种著名的转录因子,同源框A10(HOXA10)调控大量下游靶基因,从而使子宫内膜实现胚胎着床的正常功能发育。HOXA10基因表达水平的改变会影响许多其他基因的表达,包括编码转录本和非编码转录本。在我们的研究中,当HOXA10基因在 Ishikawa细胞中的表达水平升高时,通过基因芯片进行了mRNA和LncRNA表达谱筛选。共鉴定出907个mRNA和1,026个LncRNA为HOXA10过表达的Ishikawa细胞与对照细胞之间的差异表达转录本(倍数变化≥2,P值<0.05,Q值<0.05)。进一步分析发现,这些mRNA参与了各种生物学过程,如血管发育、细胞黏附、细胞周期等。此外,14个增强子样LncRNA和108个与其附近mRNA共调控的长链非编码RNA(LincRNA)被鉴定为共调控转录本。我们的结果表明,两组之间的mRNA和LncRNA表达谱存在显著差异,为进一步研究HOXA10在子宫内膜中的分子机制提供了有用信息。
