Research progress on circular RNA in oral squamous cell carcinoma / 华西口腔医学杂志

Circular RNA, a non-coding RNA that forms a covalently closed continuous loop, exists widely in eukaryotic cells. The biogenesis and biological function of this type of RNA indicate that it can play a crucial role in diseases such as tumors, neural system diseases, and cardiovascular diseases; moreover, this RNA may have great potential use as a biomarker in these diseases. Oral squamous cell carcinoma (OSCC) is a common malignancy in oral surgery that is difficult to cure, metastasizes easily, and has poor prognosis. In this review, we summarize the loop-forming mechanisms and functions of circular RNA and describe the progress of current research in the development of oral cancer.
