摘要
Circular RNAs(circRNAs) are characterized by a covalent closed-loop structure with an absence of both 5′ cap structure and 3′ polyadenylated tail. Numerous studies have found that circRNAs play an important role in various diseases and have a variety of biological regulatory mechanisms, including acting as microRNA sponges,interacting with proteins, modulating the expression of related genes and translating into peptides or proteins.CircRNAs have also been used as biomarkers for a number of diseases, which could improve clinical practice.This review summarizes the most recent advances in biogenesis and knowledge of the biological functions of circRNAs as well as the related bioinformatics databases. We specifically describe developments in understanding of circRNA functions in the field of environmental exposure-induced diseases. Finally, we focus on potential clinical implications of circRNAs to facilitate their clinical transformation into disease treatment.
