| Outline of Final Research Achievements |
Association between environmental chemicals exposure on asthma and allergies and oxidative stress marker, 8-OHdG, and existence of FLG mutation were examined among 7 years old children. There was no difference on proportion of with or without FLG mutation between allergic cases and controls. When DINP levels in dust was higher, the risk of eczema increased, only those without FLG mutation. There was no significant association between FLG mutation, environmental chemicals and asthma and allergies, and 8-OHdG did not show any modifier effect on exposure and allergies. Studies of in vitro and in silico of DEHP and its 6 metabolites activation on PPARα/γ and PXR showed that DEHP and its metabolites have activities that differ from those of the parent compound. The results obtained from the microarray analysis suggest that DEHP and MEHP might affect the gene expression of THP-1 cells via PPARα and PXR.
