    Sammanfattning : Coronary heart disease is the result of the progression of atherosclerotic lesions, and represents the major cause of death in western countries. Age, male sex, plasma cholesterol, hypertension and smoking are major risk factors for atherosclerosis. LÄS MER

  3. 2. Localization of lipoprotein lipase in mouse pancreas, kidney and placenta : impact of metabolic disturbances on cellular distribution and activity regulation

    Författare :Rakel Nyrén; Gunilla Olivecrona; Paolo Parini; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipoprotein lipase; pancreas; kidney; placenta; angiopoietin-like protein 4; high-fat diet; obesity; mice; PET CT; nutritional status; triglyceride; GPIHBP1; medicinsk och fysiologisk kemi; Medical and Physiological Chemistry;

    Sammanfattning : Lipoprotein lipase (LPL) is the key enzyme for metabolism of triglycerides in plasma lipoproteins. In recent years many new facts about the enzyme and its regulation have been uncovered. The endothelial membrane protein GPIHBP1 translocates LPL through endothelial cells and holds the enzyme in place at the luminal side of the capillary endothelium. LÄS MER

  4. 3. Steroid-Metabolizing Cytochrome P450 (CYP) Enzymes in the Maintenance of Cholesterol and Sex Hormone Levels

    Författare :Hanna Pettersson; Maria Norlin; Kjell Wikvall; Paolo Parini; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP27A1; CYP7B1; cytochrome P450; estrogen receptor; androgen receptor; cholesterol; sex hormone; hydroxylation; steroid metabolism; regulation of steroid levels; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Sammanfattning : The enzymes CYP27A1 and CYP7B1 are widely expressed in various human tissues and perform catalytic reactions in cholesterol homeostasis and endocrine signaling. We have investigated the metabolism of a synthetic oxysterol. LÄS MER
