Outline of Final Research Achievements |
Recent studies suggest that exposure to brominated flame retardants (BFR) may play a role in the development of high fat- induced obesity and metabolic disorder in liver. Ketone bodies produced by β-oxidation are utilized by acetoacetyl-CoA synthetase (AACS), the novel cytosolic ketone body-utilizing enzyme. Previously, we showed that gene expression of AACS is up-regulated by bisphenol A and high fat diet-induced obesity. Therefore, we examined effects of BFR, tetrabromobisphenol A (TBBP-A), on gene expressions in adipocyte cell lines (3T3-L1, ST-13). Treatment with TBBP-A for 24 hr was not significantly affected on lipid accumulation and mRNA expression of AACS, PPAR-gamma, SCOT and FAS in mature adipocytes. On the other hand, in non-induction adipocytes, AACS, perilipin and LSD-1 mRNA was up-regulated by TBBP-A. These results suggest that TBBP-A may cause metabolic disorders of the utilization of ketone bodies via AACS in immature adipocytes
