The nuclear receptor pregnane X receptor (PXR) and constitutive androstane receptor (CAR) are closely related transcription factors that regulate the expression of Phase I (Cytochrome P450s), Phase II drug metabolizing enzymes and drug transporter genes in response to stimulation from xenobiotics including prescription drugs. PXR and CAR knockout and humanized mouse models have proven useful in the study of drug metabolism.
The rat being bigger in size, is the preferred model system for studying drug metabolism and pharmacokinetics. Here, we report the creation and preliminary characterization of PXR and CAR knockout rats and PXR/CAR double knockout rats. Whereas, the expression of phase I and II enzymes and transporter genes were not upregulated by nuclear receptor-specific agonists in the knockout rats, confirming the disruption of respective nuclear receptor(s).
Through this webinar, which is sponsored by Horizon Discovery, participants will gain a better understanding of the benefit of rat models versus mouse models in functional studies on metabolic pathways. They will learn how rat hepatocytes can add value to drug development studies, as well as the utility of the PXR and CAR KO rat models.
Horizon Discovery manager of In Vivo R&D, Dr. Kevin Forbes, will be the speaker for this event. Forbes holds a doctorate from the University of Kentucky in plant physiology, after which he was a USDA post-doctoral fellow at the University of South Carolina. During his time in the in vivo group in St. Louis, MO USA, he has worked on developing and implementing gene editing technologies (CRISPR/Cas9 and ZFNs) for animal model generation. His primary focus has been rat ADME/TOX models for drug development. Specifically, nuclear receptor and P450 gene knock-outs and humanized rat models.
LabRoots will host the webinar May 22, 2018; beginning at 8 a.m. PDT. To learn more about this event, discover the continuing education credits offered, or to register for free, click here.
