Publication number: 20140259192Abstract: The present invention relates to the fields of knockout (KO) animal production. The invention is directed to a transgenic KO animal comprising a heterozygous or homozygous deletion or functional deletion of the gene's native 3? untranslated region (3?UTR) at least in one of its endogenous gene loci, wherein the disrupted endogenous gene is transcribed into an m RNA without its native 3?UTR.

The modified pig model displays one or more phenotypes associated with Alzheimer's disease. Disclosed is also a modified pig comprising a modified human and/or porcine APP gene, and/or PS1 gene, and/or a transcriptional and/or translational product or part thereof. The invention further relates to methods for producing the modified pig; and methods for evaluating the effect of a therapeutical treatment of Alzheimer's disease; methods for screening the efficacy of a pharmaceutical composition; and a method for treatment of a human being suffering from Alzheimer's disease are disclosed.Type: ApplicationFiled: March 6, 2008Publication date: June 3, 2010Applicant: AARHUS UNIVERSITETInventors: Arne Lund Jorgensen, Ida Elisabeth Holm, Anders Lade Nielsen, Marianne Gregers Johansen, Jannik Ejnar Jakobsen
