摘要: 软骨容易受到内外界环境影响造成损伤,但因其缺乏神经、血管和淋巴等组织,所以自我修复能力有限,在这一过程中长寿基因沉默信息调节因子1(SIRT1)发挥重要作用。软骨受损后,软骨合成分解代谢紊乱,SIRT1基因可通过影响软骨细胞炎症反应、氧化应激等因素调控软骨损伤进程。在分子机制中,SIRT1基因具有调节软骨稳态的重要作用,其可通过Notch、BMP、Wnt/β-catenin等信号通路对软骨损伤修复进行调节。在本综述中,阐述了SIRT1基因在病理生理条件下对软骨的保护作用及可能的修复机制,为恢复软骨稳态、实现软骨代谢平衡相关研究提供理论支撑。

Abstract: Cartilage is vulnerable to be damaged by internal and external environmental, but its self-repair ability is limited due to the lack of nerves, blood vessels and lymphatic tissues. In this process, longevity gene silencing information regulator 1 (SIRT1) plays an important role. After cartilage damage, cartilage anabolism and catabolism are disordered. SIRT1 gene can regulate the process of cartilage damage by influencing chondrocyte inflammation, oxidative stress and other factors. In the molecular mechanism, SIRT1 gene plays an important role in regulating cartilage homeostasis, which can be mediated by Notch, BMP, Wnt/ β-Catenin and other signal pathways that play a regulatory role in cartilage damage repair. In this review, we illustrate the protective effects of SIRT1 on cartilage under pathophysiological conditions and its possible molecular biological mechanisms, providing theoretical support for research related to restoring cartilage homeostasis and achieving cartilage metabolic balance.
