We previously carried out genetic and metabolic studies in a partially inbred herd of pigs carrying cholesterol-elevating mutations. Quantitative pedigree analysis indicated that apolipoprotein (apo)B and a second major gene were responsible for the hypercholesterolemia in these animals. In this study, we assessed LDL receptor function by three different(More)
Acyl-coenzyme A:cholesterol acyltransferase (ACAT) catalyzes the esterification of cholesterol with long chain fatty acids and is believed to play an important part in the development of atherosclerotic lesions. To facilitate the study of ACAT's role in this process, we have used the human ACAT K1 clone previously described (Chang, C. C. Y., Huh, H. Y.,(More)
The Lpb5 apolipoprotein B (apoB) allele occurs in pigs with spontaneous hypercholesterolemia. Low-density lipoprotein (LDL) from these pigs binds to the LDL receptor with a lower affinity and is cleared from the circulation more slowly than control pig LDL. However, the severity of hypercholesterolemia in pigs with the mutant apoB allele is highly variable.(More)
