  1. 1. Plant Phosphoinositide Kinases. A Study of PtdIns 4-kinases and a PtdIns 4-phosphate 5-kinase

    Författare :Tomas Westergren; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regulation; plant phosphorylation; plasma membrane; lipid kinase; divalent ion; phosphoinositide; substrate specificity; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Phosphoinositides are of particular interest in signal transduction processes as they can be sequentially phosphorylated and used as precursors for the intracellular messengers inositol trisphosphate (InsP3) and diacylglycerol (DAG) that in turn affects calcium levels and protein kinase cascades, eventually leading to a physiological response. The activity and regulation of PtdIns 4-kinases and PtdInsP kinase was studied. LÄS MER

  2. 2. Regulation of Phospholipase C and Plasma Membrane Phosphatidylinositol 4,5-bisphosphate in Insulin-Secreting Cells

    Författare :Sophia Thore; Anders Tengholm; Erik Gylfe; Peter Jones; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell biology; PLC; PIP2; insulin-secreting cell; Ca2 ; evanescent wave microscopy; phosphoinositide kinase; ATP ADP ratio; Cellbiologi; Cell biology; Cellbiologi;

    Sammanfattning : The membrane phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) is an important signaling molecule as substrate for the phospholipase C (PLC)-catalyzed formation of inositol 1,4,5-trisphosphate (IP3) and diacylglycerol, and by directly regulating e.g. ion-channels, the cytoskeleton and vesicle trafficking in various types of cells.

  3. 3. Degranulation in macrophages and other leukocytes: regulation by calcium, phosphoinositide 3-kinase, and protein kinase C

    Författare :Claes Nauclér; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lysosomal secretion; neutrophil; Clinical biology; proton pump; Klinisk biologi; exocytosis; lysosomal pH;

    Sammanfattning : Macrophages mediate innate immunity through release of cytokines, eicosanoids, reactive oxygen species as well as through phagocytosis and secretion of lysosomal enzymes. Regulation of lysosomal secretion in macrophages differs in several respects from release of specialized granules in other leukocytes. LÄS MER

  4. 4. The role of phosphatidylinositol 4-phosphate 5-kinase type І alpha (PIP5K1α) and utility of its inhibitor for targeting metastatic cancer

    Författare :Martuza Sarwar; Malmö Experimentell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate Cancer; Breast cancer; Cancer therapy; PIP5K1A; PI3K AKT signal pathway; Kinase inhibitors;

    Sammanfattning : Prostate cancer (PCa) is the most common cause of cancer-related death in men after lung cancer. Annually, more than 9000 new cases are diagnosed in Sweden and 2500 of them die each year. Metastatic prostate cancer can be treated with castration. LÄS MER
