Phenotypic Description

The PXR regulates the inducible expression of the major drug metabolising cytochrome P450 3a subfamily of enzymes, which are also responsible for the metabolism of elevated levels of bile acids. Knock out animals therefore do not respond to inducers such as pregnenolone 16alpha carbonitrile and show sensitivity to elevated bile acid levels (liver damage). The SJL background shows an unusual constititively high level of portal tract inflammation (Jones DE, Palmer JM, Kirby JA, De Cruz DJ, McCaughan GW, Sedgwick JD, Yeaman SJ, Burt AD, Bassendine MF. Experimental autoimmune cholangitis: a mouse model of immune-mediated cholangiopathy. Liver. 2000 Oct;20(5):351-6.). This strain (along with its wild type) is therefore a model for examining the effects of drugs and bile acids on portal tract inflammation.
