ABSTRACT
BACKGROUND:
Currently,there is no drug that can completely cure osteoarthritis and its pathogenesis is still unclear.Circular RNAs(circRNAs)are differentially expressed in patients with osteoarthritis and are closely associated with various pathological processes in osteoarthritis.circRNAs play an important role in various physiological and pathological processes,such as chondrocyte homeostasis,extracellular matrix formation,and inflammatory response.OBJECTIVE:
To mainly review the effects of circRNAs on pathological factors related to osteoarthritis,as well as the types and expression levels of circRNAs in osteoarthritis.METHODS:
Related articles published from 1976 to August 2023 were retrieved from CNKI,WanFang,VIP,PubMed,Medline,Web of Science and Elsevier databases.The keywords were"osteoarthritis,circular RNA,non-coding RNA,synovial tissue,chondrocytes"in Chinese and English,respectively.All the relevant articles were screened,summarized,analyzed,and finally 69 papers were included in the review. RESULTS ANDCONCLUSION:
circRNAs are non-coding RNAs widely found in eukaryotic cells,with covalently closed continuous loop structure,but with no 5'hat structure and 3'poly A tail,which are involved in multi-gene and multi-target regulatory networks and cannot be degraded by nucleic acid exonucleases(RNase R).circRNAs have a high abundance,high conservativeness and stability,and cell and tissue specificity.circRNAs have biological functions such as acting as molecular sponges for miRNAs,regulating linear RNA transcription and RNA shearing,interacting with RNA-bound proteins,and translating proteins.circRNAs regulate chondrocyte apoptosis and proliferation,degradation of cartilage extracellular matrix,and inflammation and other physiopathologic processes.circRNAs are expected to become biomarkers and potential therapeutic targets for clinical diagnosis and prognosis of osteoarthritis,and may become a new strategy for clinical treatment of osteoarthritis in the future.
