TY - JOUR AU - Lu, Minghon PY - 2020 DA - 2020/03/02 TI - Circular RNA: functions, applications and prospects JO - ExRNA SP - 1 VL - 2 IS - 1 AB - Following improvement and integration of novel genome sequencing techniques, a new stage light has been shone upon circular RNAs (circRNA) in regard to their structure and functionality. In comparison to their linear counterparts, circRNA possess a multitude of remarkable functions such as microRNA (miRNA) sponging, RNA-binding protein (RBP) regulation and translational capabilities whose research have recently gained traction. Comprehensive computational modelling and analysis have revealed the relationship between the sequence composition of circRNAs and their biogenesis and structural formation as well as spatial identification. Due to fluctuations in expressional activity in tissue-specific environments and stimulations by tumour cells, circRNAs have sparked considerable interest in being employed as plausible biomarkers in disease control and treatment as consequence of their impressive specificity and biocompatibility. Additionally, an increasing number of studies have proposed them as viable solutions to be just as competent as presently used disease markers and medicine, if not better. In this review, I briefly summarized the characteristics, biogenesis and function of circRNA and introduced the potential applications and prospects of circRNA. With vigorous research being carried out regarding their still unclear diversified roles and precise molecular structure, circRNAs are bound to become the new revolutionary perspective on cellular regulation, protein signalling and disease pathogenesis.
