Description
The discovery of microRNA (miRNA) involvement in cancer a decade ago, and the more recent findings of long non-coding RNAs in human diseases, challenged the long-standing view that RNAs without protein-coding potential are simply “junk” transcription within the human genome. These findings evidently changed the dogma that “DNA makes RNA makes protein” by showing that RNAs themselves can be essential regulators of cellular function and play key roles in cancer development. MiRNAs are evolutionarily conserved short single-stranded transcripts of 19–24 nucleotides in length. They do not code for proteins, but change the final output of protein-coding genes by regulating their transcriptional and/or translation process. Ultraconserved genes (UCGs) are non-coding RNAs with longer length (>200bp) that are transcribed from the ultraconserved genomic region. Both miRNAs and UCGs are located within cancer-associated genomic regions (CAGRs) and can act as tumor suppressors or oncogenes. In this chapter, we present principles and concepts that have been identified over the last decade with respect to our understanding of the function of non-coding RNAs, and summarize recent findings on the role of miRNAs and UCGs in cancer development. Finally, we will conclude by discussing the translational potential of this knowledge into clinical settings such as cancer diagnosis, prognosis and treatment.
