Cancer Res. 2001 Apr 15;61(8):3299-307.

Both Nrf2-/- and Nrf2+/+ mice were fed a control diet or one supplemented with either synthetic cancer chemopreventive agents [butylated hydroxyanisole (BHA), ethoxyquin (EQ), or oltipraz] or phytochemicals [indole-3-carbinol, cafestol and kahweol palmitate, sulforaphane, coumarin (CMRN), or alpha-angelicalactone].
Immunoblotting class-alpha and class-mu GST showed that constitutive expression of most transferase subunits is also reduced in the small intestine of Nrf2 mutant mice.

The agents examined, which might be expected to respond via specific nuclear receptors (CAR, AhR) as well as antioxidant response elements (AREs), included Phase I/II inducers [5,6-benzoflavone (BF, 5000mg/kg diet), diallyl sulfide (DAS, 500mg/kg BW/day), ethoxyquin (EXO, 300mg/kg BW/day) and phenobarbital (PB, 500mg/kg diet)] or pure Phase II inducers [1,2-dithiol-3-thione (DTT, 500mg/kg diet), and cyclopentadithiolthione (CPDTT, 175mg/kg BW/day)].
In genes with known AREs, the induction ratios (Levels Treated/Levels Controls) were: quinone oxidoreductase (BF, 8:1; DTT, 3.2:1; CPDTT, 3:1; DAS, 1.8:1; Exo, 1.7:1), glutatione transferase Pi (DTT, 36:1; CPDTT, 34:1; EXO, 8:1; DAS, 5:1; BF, 2.5:1), and aldehyde keto reductase 7A3 (AFAR) (DTT and CPDTT, 14:1; DAS, 6:1; EXO, 4:1; PB, 1.5:1).

In the extra-hepatic tissues using 1-chloro-2,4-dinitrobenzene as a substrate, all treatments caused an increase in transferase activity in the lung; ethoxyquin and combined methylcholanthrene plus butylated hydroxyanisole increased this activity in the kidney, whereas only the combined methylcholanthrene plus butylated hydroxyanisole increased activity in the small intestine. 5.

In this study, rats were treated with the monofunctional inducers tert-butylated hydroxyanisole, ethoxyquin, and oltipraz to study the inducibility of individual glutathione S-transferase isozymes, NADP (H):quinone oxidoreductase, gamma-glutamylcysteine synthetase, UDP-glucuronosyl transferase, and cytochrome P450 enzymes.

The constitutive GSH S-transferase (GST) activity varied from 2.9 (SJL/JCR) to 8.9 (C57BL/6NCR) mumol product formed/min/mg protein and the corresponding values for the EQ-HCl-treated mice were in the range of 15.3-25.3 mumol product formed/min/mg protein. 3.

Consumption of dietary EQ produced the expression of CYP3A, glutathione S-transferase (GST), and uridine diphosphate glucuronosyl-transferase (UDPGT) mRNA during the depuration period.

Feeding mice with anticarcinogenic antioxidants, 2 (3)-tert-butyl-4-hydroxyanisole (BHA), ethoxyquin (EQ), disulfiram (DSF), and selenite (SE) resulted in selective changes in hepatic microsomal mixed function oxidases and in other enzymatic activities which were different from those obtained by feeding phenobarbital (PB), 3-methyl cholanthrene (MC), and Aroclor (ARO).
