Vitamin C Promotes Muscle Development Mediated by the Interaction of CSRP3 with MyoD and MyoG

Previous studies have reported that vitamin C (VC), an essential nutrient, exerts beneficial effects on muscle health. However, the molecular mechanism involved in the VC-mediated regulation of muscle development is still unclear. The roles of VC in muscle development and the underlying molecular mechanisms were examined using cell and molecular biology, transcriptomics, proteomics, and animal experiments in this study. VC upregulated the expression of sodium-dependent vitamin C transporter 2 (SVCT2) and cysteine rich protein 3 (CSRP3). Additionally, VC promoted the differentiation of C2C12 cells and the repair of mouse muscle injury by upregulating the nuclear translocation of CSRP3, which subsequently interacted with MyoD and MyoG. This study provided a theoretical basis for elucidating the mechanism underlying the VC-mediated regulation of muscle development, as well as for developing animal nutritional supplements and therapeutic drugs for muscle diseases.

Automated summary

This study investigated the role of vitamin C (VC) in muscle development and identified the molecular mechanism behind it. The researchers found that VC upregulated the expression of specific proteins and promoted muscle cell differentiation and injury repair. These findings provide a theoretical basis for understanding the regulation of muscle development by VC and for the development of nutritional supplements and therapeutic drugs for muscle diseases.
