There have been an increasing number of patients with degenerative disc diseases due to the aging population. In light of this, studies on the pathogenesis of intervertebral disc degeneration have become a hot topic, and gene knockout mice have become a valuable tool in this field of research. With the development of science and technology, constitutive gene knockout mice can be constructed using homologous recombination, zinc finger nuclease, transcription activator-like effector nuclease technology and clustered regularly interspaced short palindromic repeats/Cas9 (CRISPR/Cas9) system, and conditional gene knockout mice can be constructed using the Cre/LoxP system. The gene-edited mice using these techniques have been widely used in the studies on disc degeneration. This paper reviews the development process and principles of these technologies, functions of the edited genes in disc degeneration, advantages, and disadvantages of different methods and possible targets of the specific Cre recombinase in intervertebral discs. Recommendations for the choice of suitable gene-edited model mice are presented. At the same time, possible technological improvements in the future are also discussed.
由于人口老龄化,患有椎间盘退行性疾病的患者数量不断增加。鉴于此,椎间盘退变发病机制的研究已成为热门话题,基因敲除小鼠已成为该研究领域的重要工具。随着科学技术的发展,可利用同源重组、锌指核酸酶、转录激活样效应因子核酸酶技术和成簇规律间隔短回文重复序列/Cas9(CRISPR/Cas9)系统构建组成型基因敲除小鼠,利用Cre/LoxP系统构建条件性基因敲除小鼠。运用这些技术构建的基因编辑小鼠已广泛应用于椎间盘退变研究。本文综述了这些技术的发展历程和原理、编辑基因在椎间盘退变中的作用、不同方法的优缺点以及椎间盘内特异性Cre重组酶的可能靶点。提出了选择合适基因编辑模型小鼠的建议。同时,也讨论了未来可能的技术改进。
