MicroRNA expression profiling in adult mouse liver following benzo(a)pyrene (BaP) treatment [Exiqon miRNA array]

ABSTRACT: Lack of change in microRNA expression in adult mouse liver following treatment with benzo(a)pyrene (BaP), as detected using Exiqon miRNA arrays. Adult male mice were exposed to 150 mg/kg benzo(a)pyrene (BaP) or solvent for 3 days and sampled 4 hours after the last dose. MicroRNA expression levels in adult mouse liver were measured using Exiqon miRNA arrays. Our results indicate a distinct lack of effect of BaP of miRNA expression, despite widespread changes in mRNA levels (measured using Agilent arrays). Lack of miRNA changes was confirmed with Agilent miRNA arrays. Keywords: Toxicology, miRNA Adult male B6C3F1 mice were exposed to a daily dose of corn oil (vehicle control group) or 150 mg/kg BaP (treatment group) for 3 d (n=6 per group). Mice were sacrificed at 4 h or 24 h following the last dose and liver lobes were extracted and flash frozen. Exiqon miRNA arrays were used to examine changes in miRNA transcript levels in random liver lobe sections.
