A significant correlation has been found between hepatic CYP2E1 activity and nocturnal hypoxia.[10] We had previously reported that rats exposed to IH and cigarette smoke exhibited an increase of hepatic inflammatory cytokines, a reduction of CYPs, and a decrease of the nuclear receptors pregnane X receptor (PXR), constitutive androstane receptor (CAR), and glucocorticoid receptor (GR).[11] Therefore, we hypothesized that IH-associated inflammation will independently lead to liver injury, which may further be exacerbated by another hepatic insult.
And the nuclear receptor CAR (Constitutive Androstane Receptor) is mainly expressed in liver, where it is activated by structurally diverse ligands and then regulates cytochrome P450 and other genes whose products are involved in DMEs and transporters (Tien and Negishi, 2006; Osabe et al., 2009; DeKeyser and Omiecinsk, 2010).

In his UFC 183 win over Nick Diaz, Silva failed the pre-fight drug tests for anabolic steroids Drostanolone and Androstane, and even the post-fight test for Drostanolone plus sleeping and anti-anxiety medication.
One of these receptors, the nuclear receptor subfamily 1, group I, member 3 (NR1I3, also known as the Constitutive Androstane Receptor, CAR), is an orphan nuclear receptor that was first characterized as a cell "xenosensor," and considered a master regulator of drug metabolism and excretion (1).
The study suggests triclosan may do its damage by interfering with the constitutive androstane receptor, a protein responsible for detoxifying (clearing away) foreign chemicals in the body.
Androstane causes receptor-mediated upregulation of ATP-driven xenobiotic efflux transporters at the blood brain barrier [35], while blood brain barrier flux of aluminum, manganese, iron, and other metals is suspected to contribute to metal-induced neurodegeneration (Tables 1 and 5) 36].
