1,2,3,4,7,8-Hexachlorodibenzofuran
1,2,3,4,7,8-Hexachlorodibenzofuran (1,2,3,4,7,8-HxCDF) promotes the gene expressions of CYP1A1, CYP1B1, and aryl hydrocarbon receptor repressor (AhRR) in human peripheral blood lymphocytes (PBLs). 1,2,3,4,7,8-Hexachlorodibenzofuran activates the ethoxyresorufin-Odeethylase, achieves 20% of the maximum response caused by TCDD with a BMR20TCDD of 0.115-0.143 nM.
