Fox Foundation, this model contains a knockin of the A53T-mutated SNCA gene deeming the rat SNCA gene non-functional. The knockin contains humanized amino acids for the region spanning amino acids 53-122. The resulting model expresses a humanized A53T alpha-synuclein protein without endogenous rat alpha-synuclein. This model was generated using CRISPR/Cas9 genome targeting strategies. The A53T mutation in the SNCA gene has been linked to early-onset Parkinson’s disease (PD), making this model useful for understanding alpha-synuclein biology and PD pathogenesis. --

Defects in ApoE result in disrupted transportation of lipoproteins, fat-soluble vitamins and cholesterol into the lymph systems, and then into blood. ApoE is essential for the normal metabolism of lipids. It is expressed in the liver, intestines and brain, preventing the accumulation of cholesterol-rich particles in plasma. Widely studied for its role in cardiovascular disease and lipoprotein transport, it has more recently been implicated in Alzheimer's disease and cognition, making this a useful model for the study of atherosclerosis, Alzheimer's and nerve injury. --

Homozygous null rats demonstrate increased exposure in the brain and plasma when dosed with Bcrp-specific substrates. Loss of function of Bcrp leads to improper transport of drugs across epithelial cells and increased bioavailability of Bcrp substrates. This model is useful for studying metabolism of xenobiotic compounds, tissue distribution, DMPK, efficacy, formulation, and blood brain barrier efflux. --

Homozygous animals carrying the Bdnf deletion are postnatal lethal. Reductions of BDNF have been observed in patients with Alzheimer's disease (AD), and this model may be useful for understanding the role of BDNF in AD. Bdnf is one of the most active and essential of the neurotophins, contributing to the growth and differentiation of neurons in the hippocampus, cortex and forebrain. These areas are key for cognition, learning and memory. Deficiency in Bdnf levels have been linked to a host of neurological diseases, including Alzheimer's, depression, schizophrenia and dementia, making this an important model for studying the central nervous system. --

    BSEP knockout rats HsdSage:SD-Abcb11tm1Sage GEM rats Drug-drug interactions~Cholestasis~Drug-induced cholestasis (DIC)~Transporter assays Background strain: Sprague Dawley Biallelic 8bp deletion within the Abcb11 gene Homozygous knockout rats display total loss of protein via Western blot Availability: Cryopreserved as heterozygous embryos Zygosity:Heterozygous Abcb11 encodes the bile salt export pump (BSEP) found in the liver. BSEP is critical in the secretion of bile by releasing bile salts from the liver, and mutations in BSEP have been associated with progressive familial intrahepatic cholestasis in humans. Drug induced liver injury is an important clinical issue, and may result from inhibition of BSEP. Chemical inhibition of BSEP can lead to decreased bile flow and buildup of bile salts in hepatocytes, resulting in toxicity. Understanding the potential of BSEP inhibition by drug candidates is thus of significant importance for drug discovery and development. This model is useful in studying impairment of bile secretion. --

    CAR knockout rats HsdSage:SD-NR1I3tm1Sage GEM rats Xenobiotic sensor~Cytochrome p450 pathways~Cholestasis~Hepatotoxicity~sDrug metabolism Background strain: Sprague Dawley Availability: Cryopreserved as homozygous embryos Zygosity: Homozygous CAR is involved in the induction of cytochrome p450s and is abundantly expressed in the liver and intestine. This model is useful for studying metabolism of xenobiotic compounds and hepatotoxicity. The activation of nuclear receptors, including the Pregnane X Receptor (PXR) and the Constitutive Androstane Receptor (CAR), is a common Mode of Action (MoA) for chemicals that exhibit non-genotoxic hepatocarcinogenicity in rodents. Conversely, the activation of the human PXR and/or CAR receptors is not believed to result in a carcinogenic response. Therefore, if a compound causes liver tumors in rodents, or if studies demonstrate that the compound is a nuclear receptor agonist, it is critical to unambiguously demonstrate the role of specific nuclear receptors in the rodent response, for example by using PXR or CAR KO rats. CXR has extensive experience of working with global pharmaceutical, chemical and agrochemical companies to demonstrate the absence of human relevance for nuclear-receptor mediated carcinogenicity.   --

MDR1 and BCRP are membrane-bound drug transporters expressed in the brain. Each effectively blocks specific drugs from crossing the blood-brain barrier. P-gp and Bcrp can confer multiple drug resistance to tumor cells. Absence of P-gp and Bcrp creates a functional deficiency in the blood-brain barrier and results in elevated drug levels in many tissues, making this a useful model for efflux assay, efficacy, formulation, tissue distribution, studying neurotoxicology and chemotherapeutic agents. --

DNA-PK is required for the non-homologous end joining (NHEJ) pathway of DNA repair, which rejoins double-strand breaks. It is also required for V(D)J recombination, a process that utilizes NHEJ to promote immune system diversity. Mature B and T cells are critical components for an adaptive immune system. DNA-PK knockout rats have severe combined immunodeficiency (SCID) and lack of both B and T cells, due to their V(D)J recombination defect. Rats deficient in the Prkdc gene produce no mature B, T or NK cells. This SCID rat is a useful model for cancer, xenografts, vaccine development, and autoimmune and infectious disease study. --

This model is useful for studying metabolism of xenobiotic compounds and hepatotoxicity. The activation of nuclear receptors, including the Pregnane X Receptor (PXR) and the Constitutive Androstane Receptor (CAR), is a common Mode of Action (MoA) for chemicals that exhibit non-genotoxic hepatocarcinogenicity in rodents. Conversely, the activation of the human PXR and/or CAR receptors is not believed to result in a carcinogenic response. Therefore, if a compound causes liver tumors in rodents, or if studies demonstrate that the compound is a nuclear receptor agonist, it is critical to unambiguously demonstrate the role of specific nuclear receptors in the rodent response, for example by using PXR or CAR KO rats. CXR has extensive experience of working with global pharmaceutical, chemical and agrochemical companies to demonstrate the absence of human relevance for nuclear-receptor mediated carcinogenicity. --

This double knockout model was generated by crossing together the single PXR and Car knockout rat lines.The activation of nuclear receptors, including the Pregnane X Receptor (PXR) and the Constitutive Androstane Receptor (CAR), is a common Mode of Action (MoA) for chemicals that exhibit non-genotoxic hepatocarcinogenicity in rodents. Conversely, the activation of the human PXR and/or CAR receptors is not believed to result in a carcinogenic response. Therefore, if a compound causes liver tumors in rodents, or if studies demonstrate that the compound is a nuclear receptor agonist, it is critical to unambiguously demonstrate the role of specific nuclear receptors in the rodent response, for example by using PXR or CAR KO rats. CXR has extensive experience of working with global pharmaceutical, chemical and agrochemical companies to demonstrate the absence of human relevance for nuclear-receptor mediated carcinogenicity. --
