摘要:




文题释义:
骨骼肌卫星细胞:除了骨骼肌纤维(肌细胞)之外,骨骼肌中还存在一种扁平且具有突起的细胞,它们被称为肌卫星细胞。这些细胞位于肌细胞膜和基膜之间,并具备增殖和分化的潜力,由于其位置和排列方式类似于环绕肌纤维的卫星,因此得此名。
信号通路:细胞信号转导通路指的是一系列酶促反应过程,通过这些反应,细胞外的分子信号能够穿越细胞质膜进入细胞内并发挥生物学效应。这些细胞外的分子信号,也被称为配体,包括激素、生长因子、细胞因子、神经递质以及其他小分子化合物等。

背景:近年来,运动改善骨骼肌的健康已成为学者们关注的一个重要研究内容,适宜的运动对骨骼肌具有积极的作用,其中在运动激活鞘氨醇激酶1(sphingosine kinase1,SphK1)/鞘氨醇-1-磷酸(sphingosine-1-phosphate,S1P)/鞘氨醇-1-磷酸受体2(sphingosine-1-phosphate receptor2,S1PR2)信号通路如何改善骨骼肌的健康,正受到科研人员的重视。
目的:研究运动经SphK1/S1P/S1PR2信号通路如何改善骨骼肌的健康,探索治疗相关肌肉疾病的新方法,以改善人的骨骼肌健康。
方法:检索Web of Science、PubMed、中国知网、万方和维普数据库从建库至今与文章主题相关的文献,以“signaling pathway,SphK1,S1P,S1PR2,skeletal muscle,satellite cell,myogenesis,exercise”为英文检索词,以“信号通路,SphK1,S1P,S1PR2,骨骼肌,卫星细胞,肌生成,运动”为中文检索词,最终纳入69篇文献进行分析。
结果与结论:①SphK1/S1P/S1PR2信号通路是一个复杂的调控网络,通过SphK1催化产生的S1P,与S1PR2等受体的相互作用,触发下游信号转导过程,进而调控细胞、组织、器官和系统的多种生物学功能。②SphK1/S1P/S1PR2信号通路能调控卫星细胞增殖和成肌细胞分化,改善肌生成。③文章通过文献资料调研法分析了SphK1/S1P/S1PR2信号通路的生理基础以及运动对其影响的可能性。急性有氧运动可提高骨骼肌中SphK1的表达,人体和动物研究中已证实急性和长期运动均可提高骨骼肌中S1P水平,另外研究表明长期抗阻运动可提高S1PR2在骨骼肌中的表达,部分实验结果表明急性和长期运动对肌肉或者血液中S1P水平无显著影响,出现不同结果的原因可能是选择的研究对象、方式、强度及频率不同,而具体机制尚不明确。④研究认为,运动能够促进SphK1/S1P/S1PR2信号通路在骨骼肌中的表达,调控下游相关信号通路,并且针对这一信号通路的研究可能为骨骼肌疾病的治疗提供新的策略和方法,从而改善骨骼肌健康。⑤未来应深化对SphK1/S1P/S1PR2信号通路与骨骼肌健康关联的研究,进一步揭示其与卫星细胞、成肌细胞的调控关系及与上下游通路的相互作用,挖掘其临床应用价值,制定康复方案时考虑该通路变化,探索不同运动对该通路的影响机制,并将其作为潜在治疗靶点,结合人体肌肉模型提升研究深度和准确性。

Abstract:
BACKGROUND: I
n recent years, improving the health of skeletal muscles through exercise has become an important research concern for scholars. Appropriate exercise has a positive effect on skeletal muscles. Among them, how to activate the sphingosine kinase1 (SphK1)/sphingosine-1-phase (S1P)/sphingosine-1-phase receptor2 (S1PR2) signaling pathway during exercise so as to improve the health of skeletal muscles is receiving attention from researchers.
OBJECTIVE: To investigate how exercise improves the health of skeletal muscles through the SphK1/S1P/S1PR2 signaling pathway, and to explore new methods for treating related muscle diseases in order to improve human skeletal muscle health.
METHODS: The first author searched for relevant literature from the establishment of the database to the present in the Web of Science, PubMed, CNKI, WanFang, and VIP databases. The search terms were “signaling pathway, SphK1, S1P, S1PR2, skeletal muscle, satellite cell, myogenesis, exercise” in Chinese and English. Finally, 69 articles were included for review and analysis.
RESULTS AND CONCLUSION: The SphK1/S1P/S1PR2 signaling pathway is a complex regulatory network that triggers downstream signal transduction processes by SphK1 to catalyze the interaction between S1P and receptors such as S1PR2, thereby regulating multiple biological functions of cells, tissues, organs, and systems. The SphK1/S1P/S1PR2 signaling pathway can regulate satellite cell proliferation and myoblast differentiation, improving myogenesis. The physiological basis of the SphK1/S1P/S1PR2 signaling pathway and the potential impact of exercise on it were analyzed through literature research. Acute aerobic exercise can increase the expression of SphK1 in skeletal muscle. Both human and animal studies have confirmed that acute and long-term exercise can increase the expression of S1P in skeletal muscle. In addition, studies have shown that long-term resistance exercise can increase the expression of S1PR2 in skeletal muscle. Some experimental results indicate that acute and long-term exercise have no significant effect on muscle or blood S1P levels, and the reason for different results may be due to different research subjects, methods, intensities, and frequencies selected, while the specific mechanism is not yet clear. Research suggests that exercise can promote the expression of the SphK1/S1P/S1PR2 signaling pathway in skeletal muscle and regulate downstream related signaling pathways. Research on this signaling pathway may provide new strategies and methods for the treatment of skeletal muscle diseases, thereby improving skeletal muscle health. In the future, we should deepen the research on the association between SphK1/S1P/S1PR2 signaling pathway and skeletal muscle health, further reveal its regulatory relationship with satellite cells and myoblasts as well as its interactions with the upstream and downstream pathways, explore its clinical application value, take into account the changes of this pathway when formulating the rehabilitation program, explore the specific mechanisms by which different types of exercise affect the SphK1/S1P/S1PR2 signaling pathway in skeletal muscles, and use the SphK1/S1P/S1PR2 signaling pathway as a potential therapeutic target for diseases. Further development and application of human muscle models should be developed to improve research depth and accuracy.
