| Outline of Final Research Achievements |
Brominated flame retardants (BFRs) are widely used in many consumer products and have been found as environmental pollutants. Although BFRs can disrupt the endocrine, nervous and immune systems, the association between BFRs and obesity remains unclear. Thus, our current study investigated the effects of exposure to BFRs from fetal to adult using obese mouse model. As are results, 1) exposure to decabromodiphenyl ether (decaBDE) from childhood to adult enhanced diet-induced hyperglycemia through disruption of glucose homeostasis, 2) in utero and lactational exposure to hexabromocyclododecane (HBCD) facilitated diet-induced hyperglycemia in female offspring, but not male offspring, and 3) exposure of BFRs (decaBDE or HBCD) in the co-culture system of macrophages and adipocytes increased the production of CCL2/MCP-1 and TNF-α in a dose-dependent manner. From our study, it is suggested that exposure to low doses of BFRs may enhance obesity-related health problems
