Abstract

Ischemic diseases are a major cause of mortality or disability in the clinic. Surgical or medical treatment often has poor effect on patients with tissue and organ ischemia caused by diffuse stenoses. Promoting angiogenesis is undoubtedly an effective method to improve perfusion in ischemic tissues and organs. Although many animal or clinical studies tried to use stem cell transplantation, gene therapy, or cytokines to promote angiogenesis, these methods could not be widely applied in the clinic due to their inconsistent experimental results. However, exercise rehabilitation has been written into many authoritative guidelines in the treatment of ischemic diseases. The function of exercise in promoting angiogenesis relies on the regulation of blood glucose and lipids, as well as cytokines that secreted by skeletal muscle, which are termed as myokines, during exercise. Myokines, such as interleukin-6 (IL-6), chemokine ligand (CXCL) family proteins, irisin, follistatin-like protein 1 (FSTL1), and insulin-like growth factor-1 (IGF-1), have been found to be closely related to the expression and function of angiogenesis-related factors and angiogenesis in both animal and clinical experiments, suggesting that myokines may become a new molecular target to promote angiogenesis and treat ischemic diseases. The aim of this review is to show current research progress regarding the mechanism how exercise and exercise-induced myokines promote angiogenesis. In addition, the limitation and prospect of researches on the roles of exercise-induced myokines in angiogenesis are also discussed. We hope this review could provide theoretical basis for the future mechanism studies and the development of new strategies for treating ischemic diseases.

摘要

缺血性疾病是临床上导致死亡或残疾的主要原因。对于由弥漫性狭窄引起的组织和器官缺血患者,手术或药物治疗往往效果不佳。促进血管生成无疑是改善缺血组织和器官灌注的有效方法。尽管许多动物或临床研究试图利用干细胞移植、基因治疗或细胞因子来促进血管生成,但由于实验结果不一致,这些方法无法在临床上广泛应用。然而,运动康复已被写入许多权威指南用于缺血性疾病的治疗。运动促进血管生成的作用依赖于对血糖和血脂的调节,以及运动过程中骨骼肌分泌的细胞因子,即肌动蛋白。在动物和临床实验中都发现,白细胞介素-6(IL-6)、趋化因子配体(CXCL)家族蛋白、鸢尾素、卵泡抑素样蛋白1(FSTL1)和胰岛素样生长因子-1(IGF-1)等肌动蛋白与血管生成相关因子的表达和功能以及血管生成密切相关,这表明肌动蛋白可能成为促进血管生成和治疗缺血性疾病的新分子靶点。本综述的目的是展示关于运动和运动诱导的肌动蛋白促进血管生成机制的当前研究进展。此外,还讨论了运动诱导的肌动蛋白在血管生成中作用研究的局限性和前景。我们希望本综述能为未来的机制研究和治疗缺血性疾病新策略的开发提供理论依据。
