| Outline of Final Research Achievements |
Vitamin A reduces fat mass and can contribute to the prevention of obesity. In the present study, we investigated how vitamin A reduced fat mass in a high fat-diet (HFD)-induced obese mouse model. The vitamin A-treated HFD mice (VA mice) had a significant reduction in body weight and fat mass. The energy expenditure in the VA mice significantly increased with the activation of AMP-activated protein kinase α (AMPKα) in the white adipose tissue (WAT). However, the intake of vitamin A caused some typical hypervitaminosis A. We suggest that excess intake of vitamin A reduces the fat mass in HFD-induced obese mice through enhancement of energy expenditure by activation of AMPKα in the WAT.
