摘要：Genetic effects on serum high density lipoprotein (HDL) cholesterol concentration and several parameters of a two-pool model of cholesterol metabolism were investigated in 79 baboons, the progeny of 6 sires. Significant differences (P less than 0.05) were observed among the sire progeny groups for HDL cholesterol (HDL-C), cholesterol production rate, cholesterol mass of pool A, and the rate constants KA and KAB. Rank correlations (rs) revealed that the sire progeny group means for HDL-C are closely correlated with those for the cholesterol mass of pool A (rs = 0.89), KA (rs = -0.78), and KAB (rs = -0.94). These strong correlations suggest that pool A, KA, and KAB are influenced to a large degree by the same genes that regulate HDL-C concentration. The strong inverse relationship (rs = -0.78) between HDL-C and KA suggests that the differences among these sire progeny groups for HDL-C are due chiefly to those metabolic processes which regulate cholesterol excretion from pool A. This conclusion is consistent with reports that HDL-C is a preferred precursor for bile acid synthesis.
