indole 3 carbinol/zea mays

Induction of apoptosis is an approach to suppress carcinogenesis. The effects of a 12-week treatment of female Sprague-Dawley rats with indole-3-carbinol (I3C), beta-naphthoflavone or vehicle (40% ethanol in corn oil), by oral gavages starting 3 weeks after initiation of mammary tumorigenesis with

The effects of administering indole-3-carbinol (I-3-C) on carbon tetrachloride (CCl4)-induced hepatotoxicity were examined. Mice received by gavage 0-150 mg I-3-C/kg body wt in methanol-extracted corn oil, followed 1 h later by 15 microliters CCl4/kg body wt in corn oil. Animals were sacrificed 24 h

The effects of indole-3-carbinol (I3C) on lung neoplasia induced by the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) were assessed in an A/J mouse pulmonary adenoma bioassay. Mice were administered corn oil or I3C (25 or 125 mumol/mouse/day) by gavage for 4

Indole-3-carbinol (I3C) is a dietary modulator of carcinogenesis that can reduce the level of carcinogen binding to DNA. I3C-derived products are potent inducers of certain cytochrome P-450(CYP)-dependent enzyme activities. To investigate whether the protective effects of I3C against carcinogen

Over 1 million new cases of ultraviolet radiation-induced non-melanoma skin cancers (NMSC) per year now occur in the USA and the incidence of these diseases continues to increase. New preventative strategies are required. The hypothesis tested was that dietary administration of the putative cancer

Diindolylmethane (DIM) is formed by acid catalyzed dimerization of the phytochemical indole-3-carbinol, and both compounds inhibit formation and/or growth of mammary tumors in rodents. In this study, we have investigated the aryl hydrocarbon receptor (AhR) agonist activity and inhibitory

Cruciferous vegetables contain secondary metabolites termed glucosinolates that break down to products that upregulate hepatic detoxification enzymes. We have previously shown that a mixture of four major glucosinolate breakdown products from Brussels sprouts interact to produce synergistic

3,3 Diindolylmethane (DIM) is a major digestive product of indole-3 carbinol, obtained from Brassica family vegetables such as broccoli, cabbage and Brussels sprouts. This study aimed to investigate the effects of DIM on sperm parameters, histological structures of testicular tissues, blood

Four glucosinolate derivatives were evaluated individually and as a mixture for their effects on hepatic P4501A (CYP1A), glutathione S-transferase (GST), quinone reductase (QR), glutathione reductase (G-Rd), and GSH levels. Doses of the derivatives were chosen to represent their relative abundance

This study investigated the effects of six endocrine disrupters in five different doses (0.1, 0.3, 1, 3, 10 mg/kg or microg/kg) in ethanol administered by oral gavage to bobwhite quail eggs. Six eggs each were in each dose group of coumestrol, ethynyl estradiol, indole-3-carbinol, o,p'-DDE,

Modifying effects of dietary exposure of diallyl disulfide (DAD), aspirin, DL-alpha-difluoromethylomithine (DFMO), beta-naphthoflavone (beta-NF), alpha-naphthoflavone (alpha-NF), indole-3-carbinol (I3C) and protocatechuic acid (PCA) on 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP)-induced

We have established a two-stage, medium-term rat colorectal carcinogenesis model featuring induction of neoplastic lesions within ten weeks. In the present study, we examined the ability of this model to detect weak modifiers. F344 male rats were given three subcutaneous (sc) injections of

Three indole antioxidants were compared for their efficacy to inhibit lipid peroxidation, prevent chemical hepatotoxicity and induce enzyme systems involved in the biotransformation of xenobiotics. The dietary indolyl compound indole-3-carbinol (I-3-C), and the synthetic compounds

BACKGROUND Honey bees are exposed to phytochemicals through the nectar, pollen and propolis consumed to sustain the colony. They may also encounter mycotoxins produced by Aspergillus fungi infesting pollen in beebread. Moreover, bees are exposed to agricultural pesticides, particularly in-hive
