Profile
High-throughput sequencing technologies and innovative bioinformatics tools discovered that most of the genome is transcribed into RNA. Among them, only a small percentage of the RNAs in cells translate into proteins, while the majority of them are categorized as noncoding RNAs. Several studies in the last decade have identified a large family of covalently-closed single-stranded RNAs without 5' end or 3' poly(A) tails, which are termed circular RNAs (circRNAs). Increasing evidence suggests that circRNAs act as sponges for microRNAs and RNA-binding protein (RBPs), and as templates for protein translation via cap-independent mechanisms. However, only a few circRNAs have been characterized to possess biological functions out of a million circRNAs identified in humans. Our group is interested in exploring the novel functions of these intriguing RNA circles in pancreatic β-cells and skeletal muscle regeneration.
Current Focus Areas
We are exploring the global mRNA-circRNA interactions and their effect on pancreatic beta cells.
We are trying to find the functional polypeptides translated from circRNAs in skeletal muscle.
