The Chronic Gavage Toxicity/Carcinogenicity Study of Indole-3-Carbinol (I3C) in Harlan Sprague-Dawley Rats (G823524-B), CAS No 700-06-1

ABSTRACT: Indole-3-carbinol is used as a dietary supplement and has potential use as a therapeutic agent for the prevention of various types of cancer. While substantial evidence exists that indole-3-carbinol can reduce the risk of cancers induced by several known carcinogens when administered to animals, indole-3-carbinol can also function as an initiator and tumor promoter in certain models. The carcinogenic potential of indole-3-carbinol has not been studied in a 2-year bioassay. The objective of the microarray study was to evaluate the transcriptional changes in liver from rats exposed to 0 or 300 mg/kg indole-3-carbinol. At 3 months, livers were analyzed from female Harlan Sprague Dawley rats in the 2-year gavage study of indole-3-carbinol. Female rats were administered 300 mg indole-3-carbinol/kg body weight in corn oil by gavage, 5 days per week in a 2 year toxicology study of indole-3-carbinol. Gene expression studies were performed on rat liver with samples hybridized to whole rat genome RG230_2.0 rat GeneChip arrays (Affymetrix, CA).

Gene expression analysis in rat liver after exposure to pregnenolone-16α-carbonitrile

Project description:RCCHanTM:WIST male rats were administered for 7 days by oral gavage with vehicle (corn oil) or 100 mg/kg/day of pregnenolone-16α-carbonitrile(PCN). We used microarrays to evaluate gene expression profiling in rat liver at the early phase of treatment with PCN.

microRNA expression in rat lung receiving chemopreventive agents and attenuation of cigarette smoke-induced alterations

Project description:We previously showed that exposure of rats to environmental cigarette smoke (ECS) causes extensive downregulation of microRNA expression in the lung, resulting in overexpression of multiple genes and proteins. In the present study, we evaluated by microarray the expression of 484 microRNAs in the lung of rats receiving orally chemopreventive agents, including N-acetylcysteine, oltipraz, indole-3-carbinol, 5,6-benzoflavone and phenethyl isothiocyanate, or combinations thereof. Scatterplot, hierarchical cluster, and principal component analyses showed that none of the above chemopreventive regimens appreciably affected the baseline microRNA expression, while all of them attenuated ECS-induced alterations but to a variable extent. Thus, mirnome analysis provides a new tool for predicting both safety and efficacy of cancer chemopreventive agents at early carcinogenesis stages. Keywords: cancer chemoprevention, microRNA, environmental cigarete smoke (ECS), 5,6-benzoflavone (BF), Indole 3-carbinol (I3C),N-acetylcysteine (NAC), oltipraz (OPZ), Phenethyl isothiocyanate (PEITC).

Effects of corn oil gavage on gene expression profiles of thymus in Wistar Rats

Project description:To investigate the effects of corn oil (CO), common drug vehicle, on the gene expression profiles in rat thymus with microarray technique. Female Wistar Rats were administered daily with normal saline (NS), CO 2, 5, 10 ml/kg for 14 days, respectively. Then, the thymus samples of rats were collected for microarray test and histopathology examination. The microarray data showed that 0, 40, 458 differentially expressed genes (DEGs) in 2, 5, 10 ml/kg CO group compared to NS group, respectively. The altered genes were associated with immune response, cellular response to organic cyclic substance, regulation of fatty acid beta-oxidation, et al. However, no obvious histopathologic change was observed in the three CO dosage groups. These data show that 10 ml/kg CO , that dosage has been determined as the vehicle in drug safety assessment , can cause obvious influence on gene expression in rat thymus. Our study suggest that the dosage of CO gavage as the vehicle for water-in-soluble agents in drug development should be no more than 5 ml/kg if agents’ molecular effects in thymus want to be assessed. Gene expression in thymus from female Wistar rats daily administered with 2, 5, 10 ml/kg of corn oil or 10 ml/kg of saline by gavage for 14 consecutive days were measured using Agilent Rat Whole Genome 8×*60K array.

microRNA expression in lung tumors of viny-carbamate treated and viny-carbamate and indole-3-carbinol treated mice

Project description:We examined the differential expression of miRNAs in vinyl carbamate (VC)-induced lung tumors in A/J mice and assessed if the chemopreventive agent indole-3-carbinol (I3C) reversed the effects of the carcinogen. Microarray studies revealed some up-regulated microRNAs, but down-regulation of several microRNAs in carcinogen-treated mice relative to vehicle-treated mice. Keywords: Expression micro and control RNA from control treated (3 replicates), vinyl carbamate treated (4 replicates) and vinyl carbamate and indole-3-carbinol treated mice was hybridized versus synthetic human DNA to a custom multi-organism oligonucleotide array.
