The Oatp1a/1b Cluster Knockout Mouse was developed in the laboratory of Alfred Schinkel of the Netherlands Cancer Institute in 2010. The model was generated by insertion?of?loxP?sites?into the Slco1a5 and Slco1b2 genes at?both?ends?of?the?Slco1a/1b?gene?cluster in E14 embryonic stem cells derived from 129P2/OlaHsd mice, followed by Cre-mediated?deletion and injecting the targeted cells into C57BL/6J blastocysts. Resultant chimeras were backcrossed to FVB/N mice. Expression of human OATP1B1 in the liver of transgenic mice was achieved by constructing an ApoE promoter-HCR1-driven expression cassette containing human SLCO1B1 cDNA followed by pronuclear injection into fertilized oocytes of FVB mice. Two-cell stage embryos were implanted into oviducts of pseudopregnant F1 fosters and carried to term. A founder with stable hepatic expression of human OATP1B1 was selected for further crosses with Oatp1a/1b Cluster Knockout Mouse described above. Taconic received stock in 2010. The mice were derived by embryo transfer and are maintained by incrossing of mice homozygous for both the Oatp1a/1b Cluster Knockout and the human OATP1B1 transgene.
