Genes associated with drug metabolism (Cyp2b2 and Cyp3a2), the nuclear receptors constitutive androstane receptor (CAR) and pregnane X receptor (PXR), cell proliferation (Ccnd1, Ccnb1, Ccnb2, and Stmn1), and oxidative stress (Gclm and Hmox1) were significantly induced.

A strong positive correlation between CYP2C78 and 3A72 (r=0.90, p <0.001) suggests that expression of these CYP isozymes may be under a regulation mechanism of cross-talk in which specific nuclear receptors such as constitutive androstane receptor and pregnane X receptor are involved.
