Mdr1a/b-Bcrp Knock Out Mouse

Info

Catalogue Number 153415
Antigen/Gene or Protein Targets This model encodes a triple targeted mutation with disruption of the multi-drug resistance genes Abcb1a, Abcb1b and Abcg2.
Synonyms p-glycoprotein 1, permeability glycoprotein 1, P-gp, pgp, MDR1, ABCB1, CD243 p-glycoprotein 3, BCRP/ABCG2, ATP-binding cassette sub-family G member 2, CDw338,
Model Conditional KO
Relevance P-gp, a member of the MDR/TAP subfamily, is a glycoprotein encoded in humans by the ABCB1 gene. P-gp is a well-characterized ABC-transporter responsible for transporting a wide variety of substrates across extra- and intracellular membranes.

The normal excretion of xenobiotics back into the gut lumen by P-gp pharmacokinetically reduces the efficacy of some pharmaceutical drugs and in addition, some cancer cells also express large amounts of P-gp which can further enhance that effect. This makes some cancers multi-drug resistant.
Production Details This model was generated by breeding the Mdr1a/b mutated mouse with the Bcrp mutated mouse. The Mdr1a/b model was created by sequential targeting of the two Abcb1a and Abcb1b genes in E14 ES cells. Resultant chimeras were backcrossed to FVB/N for seven generations. The Bcrp model was created by targeting the Abcg2 gene in E14 embryonic stem cells derived from 129P2/OlaHsd mice and injecting the targeted cells into FVB blastocysts.
Conditional Yes
Growth/Phenotype Keywords Albino
Mouse Genetic Background/Cross History FVB Background
Zygosity Homozygous for all three mutations.

Wild type for Nnt mutation; carries Pde6brd1 mutation
Research Area Cancer, Drug Discovery & Development
Notes The Mdr1a/b-Bcrp mouse was developed in the laboratory of Alfred Schinkel of the Netherlands Cancer Institute.

Useful in studies of drug transport, oral bioavailability and multi-drug resistance
