microRNA(miRNAs)的发现导致了我们对基因调控的基本理解的范式转变。竞争性内源性RNA(ceRNA)是最近的进入者,增加了miRNA介导的基因调控的复杂性。ceRNA是共享miRNA识别元件(MRE)从而相互调节的RNA。很明显,miRNAs作为变阻器,微调基因表达和维持各种基因网络的功能平衡。因此,编码和非编码转录物中的MRE已经进化成为基因相互作用的串扰中心,影响不同ceRNA的表达水平和活性。解码由ceRNA介导的MRE之间的串扰对于描述基因调控的复杂性至关重要,我们刚刚开始解开这种复杂性。
The discovery of microRNAs (miRNAs) has led to a paradigm shift in our basic understanding of gene regulation. Competing endogenous RNAs (ceRNAs) are the recent entrants adding to the complexities of miRNA mediated gene regulation. ceRNAs are RNAs that share miRNA recognition elements (MREs) thereby regulating each other. It is apparent that miRNAs act as rheostats that fine-tune gene expression and maintain the functional balance of various gene networks. Thus MREs in coding and non-coding transcripts have evolved to become the crosstalk hubs of gene interactions, affecting the expression levels and activities of different ceRNAs. Decoding the crosstalk between MREs mediated by ceRNAs is critical to delineate the intricacies in gene regulation, and we have just begun to unravel this complexity.
