OMIA 002063-9823 : Hyperlipidaemia/atherosclerosis due to ApoE knockout in Sus scrofa

In other species: rabbit

Possibly relevant human trait(s) and/or gene(s) (MIM number): 107741

Mendelian trait/disorder: unknown

Considered a defect: unknown

Species-specific description: This trait results from genetic modification via CRISPR/cas9: the affected animals are genetically-modified organisms (GMO).

Molecular basis: Fang et al. (2018): "clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 system (CRISPR/Cas9) was used to disrupt the ApoE gene in Bama miniature pigs. Biallelic-modified ApoE pigs with in-frame mutations (ApoEm/m ) and frameshift mutations (ApoE-/- ) were simultaneously produced. ApoE-/- pigs exhibited moderately increased plasma cholesterol levels when fed with a regular chow diet, but displayed severe hypercholesterolemia and spontaneously developed human-like atherosclerotic lesions in the aorta and coronary arteries after feeding on a high-fat and high-cholesterol (HFHC) diet for 6 months. Thus, these ApoE-/- pigs could be valuable large animal models for providing further insight into translational studies of atherosclerosis."
