(Submitter supplied) Benzo[a]pyrene (BaP) is a very extensively studied prototypical polycyclic aromatic hydrocarbons (PAHs). Previous work in our laboratory showed no changes of microRNA (miRNA) expression in liver following a 3 days exposure to BaP, suggesting a lack of miRNA transcriptional responses to aryl hydrocarbon receptor agonists and/or DNA damage. Here, we studied 25-week old male MutaTM Mouse exposed to 25, 50, and 75 mg/kg/day BaP by oral gavage for 28 consecutive days. more...

(Submitter supplied) Polycyclic aromatic hydrocarbons (PAHs) are widely distributed, carcinogenic environmental contaminants produced as a consequence of the incomplete combustion of fossil fuels. Benzo[a]pyrene (BaP) is a very extensively studied prototypical PAH. We recently reported a complete lack of change in microRNA (miRNA) expression in adult mouse liver following oral gavage with BaP despite a robust transcriptome response. more...

(Submitter supplied) Dibenzo[a,h]anthracene DB[a,h]A is a polycyclic aromatic hydrocarbon potent carcinogen. Few studies have investigated the role of DB[a,h]A on mRNA and miRNA expression. In this study a 10-week old male MutaTM Mouse were exposed to 6.25, 12.5, and 25 mg/kg/day DB[a,h]A by oral gavage for 28 consecutive days. DNA adducts were detected in the livers at each DB[a,h]A dose tested, and a dose-dependent increase in lacZ mutants was observed in the same samples. more...

(Submitter supplied) We have investigated the effect of exposure to 150 mg/kg benzo(a)pyrene (BaP) for 3 days on mRNA and miRNA expression levels in adult mouse liver. We used Agilent miRNA array platforms to assess effects of BaP exposure on miRNA expression levels. Our results indicate a distinct lack of effect of BaP of miRNA expression, despite widespread changes in mRNA levels. The data in the attached array files were used a positive control for the Agilent platform, to indicate that the platform was able to detect significant differences in abundance of miRNA between two samples with great differences in miRNA content. more...

(Submitter supplied) Adult male mice were exposed to 150 mg/kg benzo(a)pyrene (BaP) or solvent for 3 days and sampled 4 or 24 hours after the last dose. mRNA expression levels in adult mouse liver were measured using Agilent arrays. We found widespread changes in mRNA in pathways consistent with known response (xenobiotic metabolism, glutathione). We also found that BaP caused changes in the circadian rhythm pathway. We measured miRNA changes in the same samples and found no evidence for any change in transcription of miRNA as a result of the exposure. more...

(Submitter supplied) Benzo[a]pyrene (BaP) is a genotoxic carcinogen and a neurotoxicant. The neurotoxicity of BaP is proposed to arise from either genotoxicity leading to neuronal cell death, or perturbed expression of N-methyl-D-aspartate receptor (NMDAR) subunits. To explore these hypotheses, we profiled hippocampal gene expression of adult male MutaTMMouse administered 1, 35, or 70 mg BaP/kg bw per day by oral gavage for three days, by RNA-Sequencing (RNA-Seq), DNA microarrays, and real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) 24 hr post-exposure. more...
