| Outline of Final Research Achievements |
Fucoxanthin contained in brown seaweeds suppressed weight gain of white adipose tissue (WAT) through induction of mitochondrion factors including uncoupling protein 1 (UCP1) in adipose tissues. In diet-induce obese mice fed fucoxanthin, fatty acid oxidation was promoted. Induction of the brown adipocyte-like phenotype was also observed in C3H10T1/2 adipocytes treated with fucoxanthin metabolites. PGC-1alpha is suggested to be a critical factor to induce browning in white adipocytes by fucoxanthin. On the other hand, the number of progenitor cells to differentiate into beige adipocytes was demonstrated to decrease with aging.
