环状RNA在骨关节炎调控的研究进展
聂江波 金明超 方添顺 蒋豪威 李建有[摘要] 骨关节炎(osteoarthritis,OA)是常見的关节退行性病变,常表现为关节疼痛及活动受限。不可逆的软骨退变与软骨下骨骨质破坏是其最主要的病理改变。OA早期诊断困难,大多数晚期患者因此接受关节置换。环状RNA(circRNAs)是一类特殊的非编码RNAs,由碱基组成闭环结构,广泛存在真核生物中。作为调节细胞代谢的重要分子,circRNAs近年来被发现在骨关节炎中异常表达,参与软骨破坏及关节无菌性炎症等生物学行为。同时,circRNAs的环状结构使其能在血液中稳定存在,具有骨关节炎早期诊断、疗效评估及治疗的潜力。现就circRNAs及其在骨关节炎调控的研究进展展开论述。

[Abstract] Osteoarthritis (OA) is a common age-related, degenerative joint disease, with severe joint pain and functional limitation.Advancement of degenerative changes in the joint cartilage and irreversible breakage of subchondral bone are the main pathological changes of OA. Due to the difficulty in early diagnosis of OA, most of advanced patients have to receive joint arthroplasty.CircRNAs, that RNAs with closed loop structure formed by bases ......
