phenotype observed in females
phenotype observed in males
N normal phenotype
homeostasis/metabolism
• females with reduced triacyl glycerol on a high fat diet
• females with higher cholesterol levels on a normal fat diet
• more subcutaneous xanthomas than found when Apoetm1Unc is alone

cardiovascular system
• 76% reduction in atherosclerotic lesions in the aorta when on a high fat diet as compared to Apoetm1Unc
• area covered by lesions is 5% as compared to 30% in Apoetm1Unc homozygous males
• lesions 45% smaller in size in males and mostly restricted to the aortic arch rather than throughout the aortic tree
• female lesions closer in size to Apoetm1Unc controls
• smaller lesions on a low fat diet as well and also for females
• lesions composed of more densely packed lipid laden foam cells

growth/size/body
• gain significantly more weight on a high fat diet than Apoetm1Unc controls
• on a normal diet only males are significantly heavier than controls

immune system
• considerably less modified LDL is bound and cellular uptake is reduced
• native LDL binding is normal

cellular

hematopoietic system
• considerably less modified LDL is bound and cellular uptake is reduced
• native LDL binding is normal
