  • Title: Sterol synthesis in vitro in freshly isolated blood mononuclear leukocytes from familial hypercholesterolemic patients treated with probucol.
    Author: McNamara DJ, Bloch CA, Botha A, Mendelsohn D.
    Journal: Biochim Biophys Acta; 1985 Mar 06; 833(3):412-6. PubMed ID: 3970963.
    Abstract:
    Sterol synthesis rates were measured in freshly isolated blood mononuclear leukocytes obtained from familial hypercholesterolemic patients undergoing treatment with either probucol alone or probucol plus cholestyramine. Subjects with heterozygous familial hypercholesterolemia on probucol had a significant 31% reduction in mononuclear cell sterol synthesis rates as compared to control patients; sterol synthesis in cells from homozygous familial hypercholesterolemic patients on probucol did not differ from that in control subjects. Addition of cholestyramine to probucol therapy in heterozygous familial hypercholesterolemic patients caused an increase in sterol synthesis rates equal to but not greater than control values, thus negating the decreased mononuclear leukocyte sterol synthesis associated with probucol administration alone. Probucol treatment effectively decreased plasma cholesterol levels in both homozygous and heterozygous familial hypercholesterolemic subjects; however, the data suggest that the drug may exert different effects on sterol synthesis in peripheral tissues depending upon the presence or absence of cellular receptors for low-density lipoproteins.
