Modulation of hepatic and extrahepatic detoxication enzymes Cyp1a1, Cyp2a5, glutathione S-transferse Ya (GSTYa) and NAD (P) H:quinone oxidoreductase (QOR) dependent catalytic activity and mRNA levels were investigated at 1, 2, or 4 days in liver, lung, or kidney of male, adult CD57 Bl/6 mice treated sc with a single dose (85 micromol/kg) of sodium arsenite (As3+).

In the present study, we evaluated the role of As (3+)-, Cd (2+)-, and Cr (6+)-induced oxidative stress on the expression of Cyp1a1, Nqo1, and Gst ya in Hepa 1c1c7 cells.

The human hepatoma Huh7 cells were treated with sodium arsenite (NaAsO2) from 0.5 to 20 microM for 24 h.

In earlier studies, sodium arsenite treatment was shown to decrease induction of enzymatic activities associated with hepatic CYPs in rats.
With 3-methylcholanthrene as inducer, 5 microM arsenite caused a 55% decrease in CYP1A1 immunoreactive protein and enzyme activity, but only a 25% decrease in CYP1A1 mRNA.
