CCN2 or connective tissue growth factor (CTGF) is a matricellular protein that regulates several cellular processes. In skeletal muscle, CTGF is a key modulator of fibrogenesis, is increased in pathological conditions such as muscular dystrophies, and plays a major role in the pathology outcome. Overexpression of CTGF in skeletal muscle of wild-type mice results in muscle damage, fibrosis, and reduction of strength. In contrast, a decrease in CTGF in dystrophic mice increases strength and reduces damage and fibrosis. Thus, CTGF is a relevant target to study in skeletal muscle pathology and its possible modulation by different treatments or potential new drugs to develop new strategies for the treatment of muscular dystrophies. We summarize the techniques used to detect CTGF in the skeletal muscle of dystrophic mdx mice.
CCN2即结缔组织生长因子(CTGF),是一种调节多种细胞过程的基质细胞蛋白。在骨骼肌中,CTGF是纤维生成的关键调节因子,在诸如肌肉营养不良等病理状况下会增加,并在病理结果中起主要作用。野生型小鼠骨骼肌中CTGF的过表达会导致肌肉损伤、纤维化和力量下降。相反,营养不良小鼠中CTGF的减少会增加力量,并减少损伤和纤维化。因此,CTGF是骨骼肌病理学研究的一个相关靶点,以及通过不同治疗方法或潜在新药对其进行可能的调控,从而开发治疗肌肉营养不良的新策略。我们总结了用于检测营养不良mdx小鼠骨骼肌中CTGF的技术。
