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).
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.

The patents' claims cover transgenic mice having reduced constitutive androstane receptor (CAR) activity, including CAR knockout mice, as well as "humanized" mice expressing a human CAR receptor.
There are two groups of families of neurosteroids: the inhibitory neurotransmitter receptor families of pregnane neurosteroids that include allopregnanolone and aIlotetrahydrodeoxycorticosterone, and the excitatory neurotransmitter receptor families of androstane neurosteroids, such as androstanediol and etiocholanone.
Based on the accumulated evidence from data reported in the literature over the last 40 years, NGTxC may trigger hepatocarcinogenesis through different mechanisms, including the activation of Phase-1 enzymes via binding the Constitutive Androstane Receptor (CAR) (e.

Silva is currently on a temporary suspension from the NSAC after testing positive for the steroids Drostanolone and Androstane on January 9, and Drostanolone on January 31 following his UFC 183 bout against Diaz.

Induction of CYP3A4, CYP2C19, and CYP2C9 by the prenyloxycinnamic acids is most likely mediated via the pregnane x receptor (PXR), which regulates the expression of many CYPs and which is the major nuclear receptor in LS180 cells lacking the constitutive androstane receptor (CAR) (Gupta et al.

CYP1A1, CYP19A1, CYP3A4, and COMT are involved in the synthetic pathway of estrogen and testosterone; NR1I2 (PXR, pregnane X receptor) and NR1I3 (CAR, constitutive androstane receptor) regulate the transcription of cytochrome P450s, such as CYP3A4, CYP2Cs, and CYP2B6 (Wang and LeCluyse 2003; Willson and Kliewer 2002).

NSAC Chairman Francisco Aguilar said in the ESPN report that Silva also tested for another kind of steroid called androstane.
These androstene and androstane hormones, designed to restore the biological activity of cellular signaling pathways disrupted by disease and aging, have been demonstrated in humans to possess several properties with potential therapeutic benefit -- they regulate innate and adaptive immunity, reduce nonproductive inflammation and stimulate cell proliferation.
