Competitive endogenous RNA regulatory network. Most of human genome DNA has transcripts. About 2% of transcripts code for protein synthesis. The remaining noncoding RNAs include miRNAs, lncRNAs, and cirRNAs. Numerous endogenous RNAs such as mRNAs, lncRNA, and cirRNAs are under the regulation of miRNAs, and they compete for the target binding of miRNAs
