Sammanfattning : The proteins of the serpin family are primarily but not exclusively proteinase inhibitors, which share a common, similar structure. It is known that this structure undergoes major conformational changes upon cleavage in the serpin reactive site loop, and that these changes include rearrangements within the hydrophobic core of the molecule.

Sammanfattning : The liver plays an important role in the regulation of cholesterol homeostasis, therefore also in the pathogenesis of arteriosclerosis and gallstone disease. The quantitatively most important way by which cholesterol is removed from the human body is via the bile, either as free cholesterol or after transformation to bile acids. LÄS MER
3. Cytochrome P450 enzymes in the biosynthesis and metabolism of bile acids and active forms of vitamin DDetta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : Cytochrome P450 enzymes catalyzing hydroxylations in the biosynthesis and metabolism of bile acids and active forms of vitamin D3 were studied.A microsomal cytochrome P450 enzyme with a molecular mass of 53 kDa, catalyzing the 6α-hydroxylation of taurochenodeoxycholic acid was purfied from pig liver microsomes and characterized with respect to catalytic and electrophoretic properties as well as polyclonal antibodies.

4. Toxicological aspects of bile acids and human fecal water on cultered human colon carcinoma cellsDetta är en avhandling från Stockholm : Karolinska Institutet, Department of Medical Nutrition
Sammanfattning : Colorectal tumorigenesis involves activation of mutations in proto-oncogenes, such as ras and c-myc, as well as mutations that inactivate tumor suppressor genes including the APC and the p53 gene. These genetic events, in turn, lead to epigenetic changes in signal transduction pathways, which regulate processes such as cell proliferation, differentiation and apoptosis. LÄS MER
