9853009 Denison MS, Phelan D, Winter GM, Ziccardi MH: Carbaryl, a carbamate insecticide, is a ligand for the hepatic Ah (dioxin) receptor. Toxicol Appl Pharmacol. 1998 Oct;152(2):406-14.

Induction of CYP1A1 gene expression is one such response that is known to be regulated by the AhR complex.

A rapid conversion rate of carbaryl was observed with the CYP1A1 and CYP1A2 cells, where only 49.7 and 0.2% of applied carbaryl (1 mg/l), respectively, remained after 24 h, as compared to 77.7% in the non-transformed culture.

Carbaryl and thiabendazole were found to activate CYP1A1 at the level of transcription, as demonstrated by the dose-dependent increase in reporter CAT and CYP1A1 mRNAs.

Carbaryl belongs to a series of compounds that activate the CYP1A1 gene.

Studies on HepG2 and HaCaT cell lines showed that carbaryl is capable of increasing, in a dose-dependent manner, both the ethoxyresorufin rufin-O-dec, O-deethylase activity and the steady-state concentrations of CYP1A1 mRNA, suggesting a transcriptional activation of this gene.

Experimental parameters modified were concentration of (14) C-fluometuron, incubation period, and additional application of inhibitor carbaryl.

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.
Two kinds of end-points were used: cytotoxicity parameters and CYP1A1 induction.

CYP1A1 and 1A2 had the greatest ability to form 5-hydroxycarbaryl, while CYP3A4 and CYP1A1 were the most active in generation of 4-hydroxycarbaryl.
