3. 7. Regulation of energy metabolism in tumor cells : the role of hexokinase

   Författare :Firoz Kabir; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neoplasms; metabolism;

   Sammanfattning : Changes in glucose metabolism are among the most universal andfundamental metabolic alterations observed in cancer cells. Hexokinase isthe initial regulatory enzyme which controls the rate of glucose entranceinto the glycolytic pathway. The content of hexokinase in tumor cells iselevated, and most of the enzyme is bound to mitochondria. LÄS MER

4. 8. Cyclic Nucleotide Phosphodiesterase 3B: Regulation in rat adipocytes and 3T3-L1 cells

   Författare :Tova Landström; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3T3-L1 TNF-alpha; adipocyte; insulin; p70S6 kinase; mitogen-activated protein kinase; protein kinase B; phosphatidylinositol-3 kinase; phosphodiesterase 3B; cAMP; lipolysis; phosphorylation; signal transduction; Biochemistry; Metabolism; Biokemi; metabolism;

   Sammanfattning : Insulin stimulation of rat adipocytes results in phosphorylation and activation of the cyclic nucleotide phosphodiesterase 3B (PDE3B), a key enzyme in the antilipolytic signalling pathway of this hormone. In this thesis, the site phosphorylated in PDE3B upon stimulation of rat adipocytes with insulin and/or the beta-adrenergic agonist, isoproterenol is identified. LÄS MER

5. 9. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression

   Författare :Katharina Bruzelius; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; milk; Natural science; cancer; prolactin; insulin; hydrocortisone; retinoic acid; MAC-T; northern blot; two-dimensional electrophoresis; bovine mammary gland; selenium; selenoprotein;

   Sammanfattning : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. LÄS MER

7. 10. Regulation of the cytoskeleton and the adhesiveness of intestinal epithelial cells by leukotriene D4

   Författare :Ramin Massoumi; Institutionen för translationell medicin; []

   Sammanfattning : Leukotrienes belong to a family of biologically active conjugated trienes that are formed from arachidonic acid via the 5-lipoxygenase pathway and are important mediators of inflammatory reactions. The CysLT1 receptor that specifically serves as receptor for leukotriene D4 (LTD4) has been identified as a G-protein coupled receptor. LÄS MER
