1 Cytochrome P450IIE1 (CYP2E1) is induced by skatole and this induction is blocked by androstenone in isolated pig hepatocytes. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
2 Skatole, a derivative of tryptophan, is produced in the hind-gut of pigs and is metabolised via hepatic cytochrome P4502E1 (CYP2E1). Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
3 Excessive accumulation of skatole together with androstenone, a metabolite of testosterone, in adipose tissue in some pigs is a major cause of "boar taint" and is associated with defective expression of CYP2E1. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
4 Skatole induced CYP2E1 protein expression to the same degree as did acetone, a known CYP2E1 inducer. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
5 Skatole induced CYP2E1 protein expression to the same degree as did acetone, a known CYP2E1 inducer. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
6 Induction of CYP2E1 by skatole was protein-synthesis dependent. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
7 Androstenone antagonised the effect of skatole on CYP2E1 expression but did not affect the CYP2E1 protein level when added alone. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
8 These results suggest that defective expression of CYP2E1 in some pigs is due to excessive concentrations of androstenone which prevent CYP2E1 induction by its substrate skatole. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
9 These results suggest that defective expression of CYP2E1 in some pigs is due to excessive concentrations of androstenone which prevent CYP2E1 induction by its substrate skatole. Skatole cytochrome P450 family 2 subfamily E member 1 Sus scrofa
