  • Title: Chronic administration of ursodeoxycholic and tauroursodeoxycholic acid changes microsomal membrane lipid content and fatty acid compositions in rats.
    Author: Bellentani S, Chao YC, Ferretti I, Panini R, Tiribelli C.
    Journal: Biochem Biophys Res Commun; 1996 Mar 27; 220(3):479-83. PubMed ID: 8607791.
    Abstract:
    We studied the effect of oral supplementation with ursodeoxycholate (UDCA) or tauroursodeoxycholate (TUDCA) on the lipid content and fatty acid composition of rat hepatic microsomes. UDCA and TUDCA significantly increased the total amount of lipids with the exception of cholesteryl-esters. UDCA significantly increased the triglycerides and phosphatidylethanolamine (PE) microsomal content, and decreased the cholesterol/phospholipids and the phosphatidylcholine (PC)/PE ratio. Both treatments increased the percentage oleic acid and of polyunsaturated fatty acids (PUFA) in each class of lipids. UDCA and TUDCA had a different action on PUFA microsomal molar percentage of phospholipids: UDCA increased the relative percentage of PUFA in the PE fraction, while TUDCA increased the relative percentage of PUFA in the PC fraction. These changes in the hepatic lipid content and composition might in part explain both cytoprotective action of these hydrophillic bile acids and their effect on membrane fluidity.
