Abstract
1. 1. Cholesterol metabolism has been characterized in three species of New World primates, the cotton-top tamarin, the saddle-back tamarin, and the squirrel monkey. 2. 2. When fed a diet containing cholesterol, the three species exhibited differing responses of plasma cholesterol levels. 3. 3. Dietary cholesterol absorption was determined and plasma cholesterol die-away kinetics were analyzed in terms of a two-pool model. 4. 4. The results of the analyses of cholesterol turnover are consistent with the observed species-specific differences in plasma cholesterol values and cholesterol absorption. 5. 5. Cholesterol metabolism differs between the two tamarin species, as well as between the tamarins and the squirrel monkey. 6. 6. Implications of species-specific differences between tamarin species are discussed in terms of the use of tamarin species as animal models for comparative studies of cholesterol metabolism and the etiology of cancer and cardiovascular disease.
