3-MCPD (3-monochloro-1,2-propanediol) inhibit myogenic differentiation in murine skeletal myoblasts.

3-Monochloro-1,2-propanediol (3-MCPD) is a chemical compound that is unintentionally produced during food processing such as acid hydrolysis. There has been reports regarding the role of this chemical compound in reproductive toxicity, as well as genotoxicity, neurotoxicity, and kidney toxicity. In this study, the in vitro muscle toxicity of 3-MCPD was assessed using C2C12 myoblast cells. The reduction in muscle regulatory factors (MRFs), which is related to muscle differentiation, was identified as significant with the increase concentration of 3-MCPD. Also, significantly decreased protein expression in mTOR and p70S6 kinase, which are the downstream targets of the pathway associated with muscle synthesis, was also confirmed. Therefore, the inhibitory effect of 3-MCPD on muscle differentiation is considered to be the cause of suppressing mTOR and p70S6 kinase expression. In conclusion, it was confirmed that 3-MCPD inhibits muscle differentiation in C2C12 myoblasts through suppressing the expression of several genetic factors involving muscle differentiation.
