Circular RNAs as Urinary Biomarkers

Clinical Chemistry Podcast

Circular RNAs have the unique topological feature of circularity among the RNAs species. They are single-stranded, covalently closed, circular RNA molecules and are hypothesized to be generated largely through back-splicing of exons from precursor messenger RNAs. Circular RNAs were once considered as aberrant splicing by-products, which were only present in minute amounts in cells. The potential of this RNAs species as a disease biomarker is to be explored, but there are biological properties of circular RNAs which make them suitable for biomarker development. An Editorial appearing in the October 2019 issue of Clinical Chemistry by Drs. Jacky Lam and Dennis Lo discussed circular RNAs as potential urinary biomarkers.
