Chlorpromazine induction of CYP3A11 is also absent in CAR-deficient animals, but the responses to clotrimazole and dieldrin are retained, indicating that both of these inducers can also activate PXR (Pregnane X Receptor NR112).

As expected, they are completely insensitive to broad range xenobiotic inducers able to activate both receptors, such as clotrimazole and dieldrin.

In this study, we have performed Northern blot and transient transfection assays in various cell lines and shown that OCP activate human pregnane X receptor (PXR) and subsequent CYP3A4 mRNA expression.

The pregnane X-receptor (PXR) and the constitutive androstane receptor (CAR) are orphan nuclear receptors activated by a variety of ligands.
Environmental estrogens, such as the pesticides methoxychlor, endosulfan, dieldrin, DDT, and the plasticizer nonylphenol activate either PXR or both PXR and CAR.
