Objectives : Sarcopenia is a disease that leads to a decrease in skeletal muscle, and the importance of prevention and treatment thereof is increasing in an aging society. However, there is a definite limitation of exercise therapy for sarcopenia, and thus, there is an urgent need for a pharmacologic research to the treatment of sarcopenia.
Methods : 2,2’-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay was performed to confirm the antioxidant efficacy of water extract of Lacca Sinica Exsiccata (WELSE). To determine the effect of WELSE on myoblast activity, 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed. To confirm the effect of WELSE on the differentiation of myoblast into myotubes, protein expression levels of myosin heavy chain 3 (Myh3) and paired box 3/7 (pax3/7) were confirmed by immunoblot analysis. In addition, immunofluorescence microscopy was performed to confirm the effect on myotube formation of WELSE.
Results : It was confirmed that WELSE had high antioxidant activity and showed no cytotoxicity to myoblast up to 200 ㎍/㎖ concentration. Myoblast was treated with WELSE at a concentration of 100 ㎍/㎖ and differentiated for 5 days. The expression of Myh3, which forms myotubes, was promoted and the morphology of myotubes was changed and Increasing the thickness.
Conclusions : In this paper, we confirmed the excellent antioxidant efficacy of WELSE and positive effects on muscle differentiation and myotube formation. These results suggest valuable as a material for pharmaceutical research on the prevention and treatment of sarcopenia.
