Rats were dosed with BHA, butylated hydroxytoluene (BHT), ethoxyquin (EQ), dimethyl fumarate (DMF) or disulfiram (DIS) and then challenged with a toxic dose of the naphthoquinones.

11309284 McMahon M, Itoh K, Yamamoto M, Chanas SA, Henderson CJ, McLellan LI, Wolf CR, Cavin C, Hayes JD: The Cap'n'Collar basic leucine zipper transcription factor Nrf2 (NF-E2 p45-related factor 2) controls both constitutive and inducible expression of intestinal detoxification and glutathione biosynthetic enzymes. 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].
The constitutive level of NAD (P) H:quinone oxidoreductase (NQO) and glutathione S-transferase (GST) enzyme activities in cytosols from small intestine was typically found to be between 30% and 70% lower in samples prepared from Nrf2 mutant mice fed a control diet than in equivalent samples from Nrf2+/+ mice.

Cancer Res. 2000 Feb 15;60(4):957-69.

Treatment with either phytochemicals [benzyl isothiocyanate, coumarin (CMRN), or indole-3-carbinol] or synthetic antioxidants and other drugs (butylated hydroxyanisole, diethyl maleate, ethoxyquin, beta-naphthoflavone, oltipraz, phenobarbital, or trans-stilbene oxide) has been found to increase hepatic aldo-keto reductase activity toward AFB1-dialdehyde and glutathione S-transferase (GST) activity toward AFB1-8,9-epoxide in both male and female rats.

Nrf2 activators (oltipraz, ethoxyquin, and butylated hydroxyanisole) down-regulated Oatp1a1 but up-regulated Oatp2b1 mRNA expression.
All chemicals increased the expression of their well characterized target drug-metabolizing enzymes: AhR ligands increased Cyp1A1, CAR activators increased Cyp2B10, PXR ligands increased Cyp3A11, PPARalpha ligands increased Cyp4A14, and Nrf2 activators induced NAD (P) H:quinone oxidoreductase 1.

The PI3K-dependent ferritin H induction was observed by treatment with other ARE-activating agents ethoxyquin and hemin.
Consistently, PTEN restoration in Jurkat cells inhibited t-BHQ-mediated expression of ferritin H and another ARE-regulated gene NAD (P) H:quinone oxidoreductase 1.

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.
