| Outline of Final Research Achievements |
It has been reported that habitual coffee intake reduces the risk of developing lifestyle-related diseases associated with obesity and inflammation. We found that the coffee bean roasting ingredient suppresses the differentiation of adipocytes, a risk factor of obesity, by promoting the degradation of the adapter molecule IRS1 of the insulin signaling pathway, using the preadipocyte 3T3-L1 . Regarding the anti-inflammatory effect of coffee, we found that the coffee bean roasting ingredient suppresses the inflammatory response of LPS-induced mouse macrophage cells, and the effect was due to the activation of the transcription factor Nrf2 by promoting the degradation of Keap1. The above results lead to the elucidation of the effect of prevention of lifestyle diseases caused by drinking of coffee on the molecular bases.
