From: Primary genotoxicity in the liver following pulmonary exposure to carbon black nanoparticles in mice
Pulmonary Saa3 mRNA expression levels in mice following intratracheal instillation of 162 μg of TiO2, CeO2 or CB NPs measured 1, 28 and 180 days after the exposure. Saa3 mRNA levels were normalized to 18S rRNA. Particle exposed groups n = 6, vehicle control n = 6. All values are presented as mean + SD. Asterisks (**) denote P ≤ 0.01, (***) P ≤ 0.001 of Saa3 mRNA level in exposed groups versus vehicle control
