  1. 6. The Role of Protein Kinase C in the Extracellular Ca2+-regulated Secretion of Parathyroid Hormone

    Författare :Amos M. Sakwe; Lars Rask; Claes Juhlin; Uppsala universitet; []
    Nyckelord :Medical sciences; parathyroid hormone; Ca2 ; protein kinase C; calcium sensing receptor; ERK1 2; biosynthesis; secretion; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

    Sammanfattning : Parathyroid hormone (PTH) is the major physiological regulator of the extracellular Ca2+ concentration ([Ca2+]o) in the body. The secretion of this hormone is suppressed at high [Ca2+]o. LÄS MER

  2. 7. Ca2+ signalling in the pancreatic ß-cell : studies of the mechanisms for intracellular release and sequestration of Ca2+

    Författare :Per-Eric Lund; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : .... LÄS MER

  3. 8. Roles of the transient receptor potential channels and the intracellular Ca2+ channels in Ca2+ signaling in the beta-cells

    Författare :Amanda Jabin Fågelskiöld; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ca2 signaling;

    Sammanfattning : Previous studies from our group reported that pancreatic β-cells express ryanodine receptors (RyRs) that can mediate Ca2+-induced Ca2+ release (CICR). The full consequences of the activation of RyRs on Ca2+ signaling in these cells, however, remained unclear. LÄS MER

  4. 9. 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 :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.

  5. 10. ATP Dynamics in Pancreatic α- and β-cells

    Författare :Jia Li; Anders Tengholm; Erik Gylfe; Hindrik Mulder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATP; Ca2 ; β-cell; α-cell; SERCA; SOCE; muscarinic receptor; insulin secretion; glucagon secretion; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Glucose metabolism in pancreatic α- and β-cells is believed to regulate secretion of glucagon and insulin, respectively. In β-cells, ATP links glucose metabolism to electrical activity and insulin secretion. LÄS MER
