1. 1. Alpha-2 Adrenergic Receptors and Signal Transduction : Effector Output in Relation to G-Protein Coupling and Signalling Cross-Talk

   Författare :Johnny Näsman; Peter Evans; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Adrenergic; receptor; G-protein; adenylyl cyclase; cAMP; calcium; cross-talk; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

   Sammanfattning : The alpha-2 adrenergic receptor (α2-AR) subfamily includes three different subtypes, α2A-, α2B- and α2C-AR, all believed to exert their function through heterotrimeric Gi/o-proteins. The present study was undertaken in order to investigate subtype differences in terms of cellular response and to explore other potential signalling pathways of α2-ARs. LÄS MER

   Sammanfattning : Prostate cancer is one of the leading causes of cancer-related deaths in men worldwide, with 10,000 new cases/year diagnosed in Sweden. In this context, there is an urgent need to identify new biomarkers to detect prostate cancer at an initial stage for earlier treatment intervention. LÄS MER

4. 3. The Tyrosine Kinase GTK : Signal Transduction and Biological Function

   Författare :Cecilia Annerén; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinases; GTK; SHB; proliferation; survival; differentiation; β cells; pancreatectomy; cytokines; diabetes; PC12 cells; NGF; streptozotocin; focal adhesion kinase; RAP1; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

5. 4. Mechanisms of Integrin Signal Transduction

   Författare :Anne Stefansson; Staffan Johansson; Annika Armulik; Björn Öbrink; Uppsala universitet; []
   Nyckelord :Cell biology; Integrin; Integrin signalling; PI3K; Akt PKB; Integrin transmembrane domain; cell spreading; Cellbiologi;

   Sammanfattning : Integrins are a protein family of cell surface receptors, expressed in all cell types in the human body, except the red blood cells. Besides their importance in mediating physical connections with the surrounding environment, the integrin family members are also vital signalling mediators. LÄS MER

7. 5. 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.
