2. 1. Cytochrome P450 Enzymes in Bile Acid Biosynthesis and Fatty Acid Metabolism : Studies on Members of the Porcine CYP4A and CYP8B Subfamilies

   Author : Kerstin Lundell; Kjell Wikvall; Ronnie Hansson; Stefan Alexson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; cytochrome P450; bile acids; fatty acids; CYP4A; CYP8B; genome; porcine; hyocholic acid; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi; farmaceutisk biokemi; Pharmaceutical Biochemistry;

   Abstract : The present investigation is devoted to studies on porcine members of the cytochrome P450 4A (CYP4A) and CYP8B1 subfamilies, which are involved in bile acid biosynthesis and fatty acid metabolism. Hyocholic acid is considered to fulfil the requirements for trihydroxy bile acids in the domestic pig (Sus scrofa) in the absence of cholic acid. READ MORE

4. 2. Studies on the regulatory role of cholic acid in cholesterol metabolism

   Author : Charlotte Murphy; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Cholesterol is essential for normal growth and development in both man and mouse. However, excess cholesterol can be harmful leading to diseases such as atherosclerosis and gallstones. Once formed cholesterol cannot be catabolised by the body and must therefore be converted to other compounds for excretion. READ MORE

5. 3. Enzymes in different pathways of bile acid biosynthesis

   Author : Catrin Furster; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biochemistry; biokemi;

   Abstract : Enzymes catalyzing side chain hydroxylations and dehydrogenation/isomerization in different pathways of bile acid biosynthesis were studied.Pig liver mitochondrial sterol 27-hydroxylase (CYP27A) was found to catalyze 24- and 25-hydroxylation of cholesterol in addition to the known 27-hydroxylation.

6. 4. Intrahepatic cholestasis of pregnancy

   Author : Anna Glantz; Göteborgs universitet; []
   Keywords : Intrahepatic cholestasis of pregnancy ICP ; pruritus; fetal risk; ursodeoxycholic acid; dexamethasone; ABCB4-gene; haplotypes; sulphated progesterone metabolites;

   Abstract : Intrahepatic cholestasis of pregnancy (ICP) is a condition that has been reported to be associated with an increased fetal risk. A prospective study of ICP was conducted in the Västra Götaland region of Sweden between February 1, 1999 and January 31, 2002. READ MORE

7. 5. Modulation of bile acid and cholesterol metabolism in health and disease

   Author : Cecilia Gälman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Bile acids - cholesterol - gallstone - cholic acid - cholestyramine - high performance liquid chromatography - species - C4 - 7alpha-hydroxy-4-cholesten-3 -one cholesterol 7alpha-hydroxylase - lipoproteins - hyperlipidemia - statins - resins - diurnal variation - ASBT - 3-hydroxy-3-methylglutaryl coenzyme A;

   Abstract : An increased level of plasma cholesterol is associated with premature development of atherosclerosis. It is therefore important to understand the regulation of plasma cholesterol. Stimulation of hepatic bile acid synthesis is a strategy to reduce plasma cholesterol. This partly occurs due to an induction of hepatic LDL receptors. READ MORE
