Abstract
The cancer transcriptome is characterized by aberrant expression of both protein-coding and noncoding transcripts. Similar to mRNAs, a significant portion of the noncoding transcriptome, including long noncoding RNAs and pseudogenes, harbors microRNA (miRNA)-response elements (MRE). The recent discovery of competitive endogenous RNAs (ceRNA), natural decoys that compete for a common pool of miRNAs, provides a framework to systematically functionalize MRE-harboring noncoding RNAs and integrate them with the protein-coding RNA dimension in complex ceRNA networks. Functional interactions in ceRNA networks aid in coordinating a number of biologic processes and, when perturbed, contribute to disease pathogenesis. In this review, we discuss recent discoveries that implicate natural miRNA decoys in the development of cancer. Significance: Cross-talk between ceRNAs through shared miRNAs represents a novel layer of gene regulation that plays important roles in the physiology and development of diseases such as cancer. As cross-talk can be predicted on the basis of the overlap of miRNA-binding sites, we are now one step closer to a complete functionalization of the human transcriptome, especially the noncoding space.
