Silica nanoparticles trigger hepatic lipid-metabolism disorder in vivo and in vitro.

ABSTRACT:

Background

As a promising nanocarrier in biomedical fields, silica nanoparticles (SiNPs) could transfer from the circulatory system to multiple organs. Among these, blood-liver molecular exchange is a critical factor in biological response to NPs. However, the potential effect of SiNPs on hepatic lipid metabolism is unclear. In this study, we employed three models to attempt discover whether and how SiNPs disturb hepatic lipid metabolism in vivo and in vitro.

Methods

Firstly we used ICR mice models to evaulated the effects of SiNPs on the serum and hepatic lipid levels through repeated intravenous administration, meanwhile, the protein expressions of protein markers of lipogenesis (ACC1 and FAS), the key enzyme of fatty acid β-oxidation, CPT1A,and leptin levels in liver were
