16411658 Jiang H, Vudathala DK, Blair IA, Penning TM: Competing roles of aldo-keto reductase 1A1 and cytochrome P4501B1 in benzo [a] pyrene-7,8-diol activation in human bronchoalveolar H358 cells: role of AKRs in P4501B1 induction. Chem Res Toxicol. 2006 Jan;19(1):68-78.

P4501B1 induction was blocked in AKR1A1 transfectants by the AKR1A1 inhibitor (sulfonylnitromethane), the o-quinone scavenger (N-acetyl-l-cysteine), or the cytosolic AhR antagonist (diflubenzuron).

Finally, in competitive binding studies using a 9S-enriched fraction of HepG2 cytosol, DFB was capable of displacing [(3) H]-2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) from its Ah receptor binding site.

We therefore tested the comparative acute and chronic toxicity of chemicals belonging to the major insecticides families (DDT, malathion and tetrachlorvinphos, carbaryl, cypermethrin, diflubenzuron), in hepatocytes, HepG2 and HaCaT cell lines.
