Vaccine, 2012
In the present study, we investigated hepatic mRNA expression and activities of CYP3A and 2C in entire, surgically castrated and pigs vaccinated with Improvac. Additionally, we examined the mRNA expression of the two nuclear receptors pregnane X receptor (PXR) and constitutive androstane receptor (CAR), known to regulate CYP3A and 2C mRNA expression ...
