Summary

Gene targeting was used to replace the endogenouse murine APOE gene with the human APOE3 allele. On a standard diet, homozygous mice have normal cholesterol and triglyceride levels, but are more susceptible than wild-type animals to diet-induced atherosclerosis (Sullivan et al., 1997); however, they are not as vulnerable as mice with APOE4 Targeted Replacement (Knouff et al., 1999).

Modification Details

Targeted replacement of the endogenous mouse APOE gene with the human APOE3 allele. Targeting vector contained exons 2-4 of human APOE3.
