Competing Endogenous RNAs in Hepatocellular Carcinoma-The Pinnacle of Rivalry.

The role of noncoding transcripts in gene expression is nowadays acknowledged to keep various diseases at bay-despite being referred to as "junk" DNA several years ago. Believed to be at the heart of multiple regulatory pathways, microRNAs (miRNAs) are small noncoding RNAs (ncRNAs) involved in posttranscriptional gene regulation. Recently, the discovery of ncRNAs that compete for shared miRNA pools has dimmed the light on the solo performance of miRNAs in genomic regulation.
