1. 1. Hormone-Sensitive Lipase and Protein Kinase B; Molecular characterization in testis, adipose tissue and pancreatic beta cells

   Författare :Lena Stenson; Signaltransduktionsforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal transduction; pancreas; beta cells; adipocyte; insulin; Akt; protein kinase B; spermatogenesis; cholesterol esterase; hormone-sensitive lipase; testis; cAMP; Proteins; enzymology; Proteiner; enzymologi;

   Sammanfattning : Hormone-sensitive lipase (HSL) and protein kinase B (PKB) are enzymes that in different ways are associated with lipid metabolism. While HSL is the well-known lipolytic enzyme responsible for hydrolysis of stored triacylglycerols in adipose tissue, PKB is a recently identified serine/threonine protein kinase, ubiquitously expressed and involved in signal transduction pathways induced by insulin and growth factors.

3. 2. Phenotypic modulation of vascular smooth muscle in organ culture

   Författare :Anders Lindqvist; Islet cell physiology; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smooth muscle; proliferation; PDGF; Physiology; energy metabolism; calcium; Fysiologi;

   Sammanfattning : Contraction of blood vessels for the regulation of blood flow and pressure is dependent on vascular smooth muscle cells (VSMC) located in the medial layer of the vascular wall. Adult, differentiated VSMC have a well developed contractile system and a low rate of proliferation. LÄS MER

4. 3. Characterization of a new amino acid transport system in human epidermal Langerhans cells

   Författare :Niels Bendsöe; Lund Dermatologi och venereologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amino acid transport; energy charge; epidermis; glycolysis; lactate; Langerhans cells; L-dopa; mitochondria; omeprazole; Dermatology; venereology; Dermatologi; venereologi;

   Sammanfattning : Based on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. LÄS MER

5. 4. Tryptophan-related Neurotransmission in the Brain: Disturbances Associated with Experimental Hepatic Encephalopathy

   Författare :Peter B F Bergqvist; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tetrodotoxin; serotonin; release; rat; quinolinic acid; potassium; chloroamphetamine; noradrenaline; neurotransmission; microdialysis; hepatic encephalopathy; fenfluramine; drug safety; dopamine; coma; citalopram; ammonia; calcium; brain; tryptophan; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

   Sammanfattning : In the present study, L-tryptophan (TRP)-related disturbances in the brain in experimental hepatic encephalopathy (HE) were investigated. The endogenous NMDA-receptor agonist and L-TRP metabolite quinolinic acid (QUIN) has been suggested to be involved in the pathogenesis of HE. LÄS MER

7. 5. Enterostatin - target proteins and intracellular mechanisms. Function in food intake and energy metabolism

   Författare :Karin Berger; Molekylär endokrinologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP; energy metabolism; insulin; uncoupling protein; beta-casomorphin; opiate; SK-N-MC; INS-1; Medicin människa och djur ; Medicine human and vertebrates ; fat intake; F1F0-ATP synthase; appetite; enterostatin; satiety; obesity;

   Sammanfattning : Hunger and satiety are the results of complex neural events that involve several neurotransmitters and peptides. Enterostatin is an appetite-regulating peptide released in the intestine in response to fat ingestion. Enterostatin specifically decreases fat intake, but has also metabolic effects like inhibition of insulin secretion. LÄS MER
