Pomegranate Juice Effects on Cytochrome P450s Expression: In Vivo Studies
Ana Faria,Rosario Monteiro,Isabel Azevedo,Conceicao Calhau 한국식품영양과학회 2007 Journal of medicinal food Vol.10 No.4
Beneficial health effects have recently been claimed for pomegranate juice. In vitroand in vivo studies havedemonstrated its anti-atherosclerotic capacity, chemoprevention and chemotherapy of prostate cancer, and antiproliferative,apoptotic, and antioxidant activity, among others. On the other hand, there is a complex interplay between tumor initiation,promotion, and progression and xenobiotic biotranformation. This led us to investigate the effect of pomegranate juice con-sumption on cytochrome P450 (CYP) activity and expression. For this purpose, male mice consumed this fruit juice for 4over, the activity of CYP isoform 2E1 and expression of the main CYP isoforms, namely, CYP1A1/2, CYP2E1, and CYP3A,were also assessed. It was found that pomegranate juice consumption decreased total hepatic CYP content as well as the ex-pression of CYP1A2 and CYP3A. Prevention of procarcinogen activation through CYP activity/expression inhibition may beinvolved in pomegranate juice’s effect on tumor initiation, promotion, and progression.
