Gene targeting was used to replace the endogenous murine APOE gene with the human APOE4 allele. The mice are at increased risk of atherosclerosis compared with wild-type animals or mice expressing human APOE3. On a standard chow diet the mice have normal plasma levels of cholesterol and triglycerides, but altered relative levels of plasma lipoprotein particles. On a high fat diet they have elevated cholesterol, APOE, and APOB-48 compared with mice expressing human APOE3 (Knouff et al., 1999).
Targeted replacement of the endogenous murine APOE gene with the human APOE4 allele; targeting construct contained exons 2–4 of APOE4.
