Aged black garlic (Allium sativum L.) and aged black elephant garlic (Allium ampeloprasum L.) alleviate obesity and attenuate obesity-induced muscle atrophy in diet-induced obese C57BL/6 mice

초록

Garlic (Allium sativum L.) is a primary dietary component worldwide because of its health benefits and use as a traditional medicine. Elephant garlic (Allium ampeloprasum L.), a related species in the same genus, is less intense and sweeter than A. sativum. The object of this study was to investigate the alleviative effects of aged black garlic (ABG) and aged black elephant garlic (ABEG) on obesity and muscle atrophy induced by obesity in high fat dietinduced obese mice. We demonstrated that ABG and ABEG alleviated obesity and muscle atrophy and enhanced myogenic differentiation and myotube hypertrophy, and this effect was mediated by the upregulation of Akt/ mTOR/p70S6K signaling. Furthermore, a candidate bioactive compound of ABG and ABEG was suggested in this study through analysis using gas chromatography-mass spectroscopy and ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectroscopy. In conclusion, ABG and ABEG may alleviate obesity and treat obesity-induced muscle atrophy.
