Changes in cholesterol homeostasis and acute phase response following pulmonary exposure to multi-walled carbon nanotubes links carbon nanotube exposure to risk of cardiovascular disease
Ontology highlight
ABSTRACT: Adverse lung effects in rodents following pulmonary exposure to multi-walled carbon nanotubes (MWCNT) are well documented. However, systemic effects are less understood. Prospective epidemiological studies have shown increased cardiovascular disease risk after pulmonary exposure to airborne particles, which has led to concerns that inhalation exposure to MWCNT might pose similar risks. We used high-content genomics tools to compare hepatic responses after exposure to a short, entangled MWCNT to the hepatic responses after exposure to a long, stiffer MWCNT at the global transcriptomic level. Female C57BL/6 mice were exposed by single intratracheal instillation to 162 M-BM-5g/mouse of a short MWCNT (NRCWE-26 (NC-7000), 847M-BM-1102 nm in length) or long MWCNT (NM-401 (CP-0006-SG), 4048M-BM-1366 nm in length). Liver tissues were harvested 24 h, 3 d and 28 d after exposure. This experiment examined the pulmonary transcriptional response of female C57BL/6 mice exposed to NRCWE-26, a short multi-walled carbon nanotube, and NM-401, a long multi-walled carbon nanotube, at three doses: D1 (18 M-NM-
