摘要
背景:肌少症是一种进行性、广泛性骨骼肌疾病,与老年人骨关节炎、骨折、肢体残疾和死亡的发生密切相关。建立肌少症相关动物模型对了解肌少症病理生理机制以及找出有效治疗策略至关重要。目的:综述肌少症小鼠模型的评价标准及肌少症小鼠模型的造模方法,并分析比较各种造模方式的优缺点,以期为肌少症的研究与诊疗提供参考。方法:以“肌少症,肌肉减少症,肌肉衰减症,骨骼肌衰老,小鼠模型,动物模型”为中文检索词,检索公式为“(肌少症OR肌肉减少症OR肌肉衰减症OR骨骼肌衰老)AND(小鼠模型OR动物模型)”;以“sarcopenia,skeletal muscle aging,mouse models,animal models”为英文检索词,检索公式为“(Sarcopenia OR Skeletal muscle aging)AND(Mouse model OR Animal models)”,检索中国知网、万方数据库和PubMed数据库在2010年1月至2022年10月期间与主题相关的文献,最终纳入59篇文献进行分析。结果与结论:①SAMP8小鼠造模时间较快,且肌肉萎缩类型与人类肌少症患者变化一致,因此是较为理想的模型;②手术法虽可以成功诱导肌肉萎缩,但需精确的手术操作,难度较大且较耗费时间;后肢悬吊法小鼠造模与老年人较类似,可视为老年肌少症的有效模型;③试剂注射造模虽操作简单,但无论是试剂的给药剂量及给药天数等尚不明确,需进一步研究;④转基因小鼠模型应用较少,其模型稳定性需进一步研究;⑤探索出一种成本低、耗时短并能高度模拟人体肌少症的小鼠模型仍是未来的研究方向。
BACKGROUND:Sarcopenia is a progressive,generalized skeletal muscle disease that is closely related to the occurrence of osteoarthritis,fractures,limb disability and death in the elderly.Establishing animal models of sarcopenia is essential to understand the pathophysiology of sarcopenia and to identify effective treatment strategies.OBJECTIVE:To review the evaluation criteria of mouse models of sarcopenia and the modeling methods of mouse models of sarcopenia,and to analyze and compare the advantages and disadvantages of various modeling methods,in order to provide reference for the research and diagnosis and treatment of sarcopenia.METHODS:“Sarcopenia,skeletal muscle aging,mouse model,animal model”in Chinese and English were used as Chinese and English search terms,respectively.The search formula was“(sarcopenia OR skeletal muscle aging)AND(mouse model OR animal model).”CNKI,WanFang and PubMed were searched for related articles published from January 2010 and October 2022.A total of 59 articles were finally included for analysis.RESULTS AND CONCLUSION:There is a faster modeling time in SAMP8 mice and the type of muscle atrophy is consistent with that of patients with sarcopenia.Therefore,it is an ideal model.Although the surgical method can successfully induce muscle atrophy,it requires precise surgical operation,which is difficult and time-consuming.Hindlimb suspension modeling in mice is similar to that of the elderly and can be regarded as an effective model of senile sarcopenia.Although reagent injection molding is simple to perform,both the dose and number of days of administration of reagents are not clear and need to be further investigated.Transgenic mouse models are less commonly used and their model stability needs further study.The search for a mouse model with low cost,short time consumption and high simulation of human sarcopenia is still a future research direction.
