转化生长因子β信号与肌肉调控

BACKGROUND: Transforming growth factor-β signaling widely existing in cells mediates cell growth, proliferation, migration, differentiation, and apoptosis. The activation of transforming growth factor-β signaling can result in muscular dystrophy. However, there have been some contradictions regarding the effects of the transforming growth factor-β signaling on muscular dystrophy. OBJECTIVE: To summarize the latest progress in the effects of the transforming growth factor-β signaling on muscle mass and function regulation to provide the solutions for the treatment of muscular dystrophy. METHODS: A computer-based online search was conducted in PubMed and Wanfang databases from 2005 to 2015 to screen the relevant literatures using Chinese and English key words “transforming growth factor-β, muscle, regulation mechanism, treatment”. A total of 102 literatures were retrieved, and 22 eligible literatures were included, summarized, and analyzed. RESULTS AND CONCLUSION: The activation of transforming growth factor-β signaling as a common cause of most muscle disorders promotes the activation of muscle satellite cells, differentiation of myocytes, myoblast infusion, the expression of muscle-specific proteins, and the inhibition of collagen synthesis, which facilitates muscular fibrosis and scar formation. Transforming growth factor-β signaling is involved in Duchenne muscular dystrophy, spinal scoliosis, type I diabetes induced skeletal muscle regenerative disorders, myocardial and cardiac remodeling. The inhibition of transforming growth factor-β signaling may result in incomplete muscle recovery. 中国组织工程研究杂志出版内容重点：组织构建；骨细胞；软骨细胞；细胞培养；成纤维细胞；血管内皮细胞；骨质疏松；组织工程
