Kimura et al. reported that in the gastrocnemius muscle of a primary sarcopenia model animal fed with MCT, the mRNA expression of Myh3, which is involved in muscle regeneration from satellite cells, was significantly higher compared to the LCT-fed group, while the mRNA expression of Murf1 (a factor that promotes muscle breakdown in muscle cells) was significantly lower [84]. The gene discussed is MYH3; the disease is sarcopenia.
