Cardiac miRNA expression (random section containing both ventricles) in C57BL/6 mice intratracheally instilled with Printex 90 carbon black nanoparticles
Ontology highlight
ABSTRACT: C57BL/6 mice were exposed to vehicle or 0.162 mg carbon black nanoparticles by intratracheal installation and were sacrificed 1, 3 and 28 days post-exposure. Gene expression was investigated in two sets of mice treated according to the identical exposure protocol. MicroRNAs were investigated in the second set of mice. C57BL/6 mice were exposed to 0.000 or 0.162 mg Printex 90 and were sacrificed 1, 3 and 28 days after exposure. Individual total RNA enriched with small RNA from 6 mice per treatment group (control and 0.162mg) was hybridized to 8 x 15K Agilent miRNA slides.
Project description:miRNAs were measured in mice exposed to vehicle control (0.9% NaCl MilliQ water containing 10% v/v acellular BAL) or 0.162 mg Printex 90 in vehicle by intratracheal instillation and sacrificed 1, 3 and 28 days after exposure. C57BL/6 mice were exposed to 0.000 or 0.162 mg Printex 90 and sacrificed 1, 3 and 28 days after exposure.

Project description:We investigated hepatic mRNA profiles of female mice exposed to 0.162 mg Printex 90 carbon black nanoparticles by single intra-tracheal instillation. We examined responses to this dose 1, 3 and 28 days after exposure, alongside respective controls. We show that genes part of the 3-hydroxy-3-methyl-glutaryl-CoA reductase pathway to be up-regulated by exposure to Printex 90. individual total RNA (200 ng) from 6 mice per treatment group (control and 0.162mg) and universal reference total RNA (Stratagene, Mississauga, ON, Canada) was used to synthesize double stranded cDNA.

Project description:miRNAs were measured in pregant mice exposed to vehicle control (nanopure water) or a cumulative dose of 0.268 mg Printex 90 in vehicle by intratracheal instillation and sacrificed at weaning (26-27 days after exposure). Pregnant mice were exposed to vehicle control (nanopure water) or a cumulative dose of 0.268 mg Printex 90 in vehicle by intratracheal instillation. Doses of 0.067 mg were delivered 4 times in pregnant females on gestational days 7, 10, 15 and 18. Mice were sacrificed at weaning (26-27 days post-exposure).

Project description:We investigated pulmonary mRNA profiles of female mice exposed to 0.018, 0.054 and 0.162 mg Printex 90 carbon black nanoparticles by single intra-tracheal instillation. We examined responses to these doses 1, 3 and 28 days after exposure, alongside respective controls. This study demonstrates widespread changes in inflammatory and acute phase response genes that persisted to 28 days at the highest exposure dose. Changes relevant to sterol and terpenoid biosynthetic pathways were also observed.
