Repression of PXR-mediated induction of hepatic CYP3A gene expression by protein kinase C.


Pregnane X receptor (PXR, NR1I2) regulates the inducible expression of the 3A sub-family of cytochrome P450 genes (CYP3A). CYP3A enzymes are responsible for the oxidative metabolism of a wide array of endobiotic and xenobiotic compounds. Hepatic CYP3A gene expression is rapidly down-regulated during inflammation and sepsis. There are twelve protein kinase C… (More)
