Related Genotype: a/aDescription
Mice carrying the human apolipoprotein A-I transgene show a two fold increase in total plasma cholesterol levels and greater than a four fold decrease in the levels of mouse apoAI. Homozygous transgenic mice exhibit reduced susceptibility to diet induced fatty streak lesions. Mice homozygous for the transgenic insert are viable, fertile and normal in size. This human apolipoprotein AI transgene is under the control of its natural promoter. The Jackson Laboratory imported mice derived from the founder line A2 as described in Rubin EM, et al., 1991.Development
A transgenic construct containing the entire human apolipoprotein A-I gene including the promoter, APOA1, was injected into fertilized C57BL/6 mouse eggs. Founder line A2 was subsequently established.

- homeostasis/metabolism phenotype
- abnormal lipid homeostasis (MGI Ref ID J:92450)
- HDL particle size has a bimodal distribution with two peaks at 8.5 and 10.5 nm compared to the single peak at 9.9 nm for non-transgenic controls
