A given mRNA can be regulated by interactions with miRNAs and in turn the availability of these miRNAs can be regulated by their interactions with alternate mRNAs. The concept of regulation of a given mRNA by alternate mRNA (competing endogenous mRNA) by virtue of interactions with miRNAs through shared miRNA response elements is poised to become a fundamental genetic regulatory mechanism. The molecular basis of the mRNA-mRNA cross talks is via miRNA response elements, which can be predicted based on both molecular interaction and evolutionary conservation. By examining the co-occurrence of miRNA response elements in the mRNAs on a genome-wide basis we predict competing endogenous RNA for specific mRNAs targeted by miRNAs. Comparison of the mRNAs predicted to regulate PTEN with recently published work, indicate that the results presented within the competing endogenous RNA database (ceRDB) have biological relevance.
特定的信使核糖核酸(mRNA)可通过与微小核糖核酸(miRNA)相互作用来调控,反过来,这些miRNA的可用性又可通过它们与其他mRNA的相互作用来调控。凭借与共享的miRNA反应元件相互作用,由其他mRNA(竞争性内源性mRNA)对特定mRNA进行调控的概念,有望成为一种基本的基因调控机制。mRNA与mRNA之间相互作用的分子基础是通过miRNA反应元件,其可基于分子相互作用和进化保守性来预测。通过在全基因组范围内检查mRNA中miRNA反应元件的共现情况,我们预测了针对miRNA靶向的特定mRNA的竞争性内源性RNA。将预测调控第10号染色体缺失的磷酸酶及张力蛋白同源物(PTEN)的mRNA与最近发表的研究进行比较,结果表明竞争性内源性RNA数据库(ceRDB)中的结果具有生物学相关性。
