General Information

Transgene: APOE KI mice (see Hamanaka, 2000) were backcrossed onto a C57BL/6J (B6) inbred background and mated to ZP3-cre tg mice to remove the neo cassette through cre-mediated loxP excision, and the resulting offspring inherited the targeted allele lacking the neo tag.

Mutation: Replaced mouse Apoe with human APOE3

Promoter: Mouse Apoe

Mouse Strain: 129P2/OlaHsd (ES cell line E14TG2aIV). Backcrossed, N8.

Phenotype

Neuropathological Analysis:

APOE abundance in the brains of APOE3 KI animals and intermediate serum cholesterol levels when compared to APOE2 and APOE4 KI animals. APOE3 KI mice crossed with APP B6-R1.40 mice and the bigenic mice had slightly higher levels of brain cholesterol relative to non-tg animals.
