  2. 1. Oscillatory Ca2+ signaling in glucose-stimulated murine pancreatic β-cells : Modulation by amino acids, glucagon, caffeine and ryanodine

    Author : Meftun Ahmed; Per Lindström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; pancreatic β-cells; islets of Langerhans; glucose; Ca2 oscillations; Ca2 transients; potassium; ryanodine; caffeine; glucagon; cAMP; inositol 1; 4; 5-trisphosphate; fura-2; glycine; alanine; arginine; Ca2 channels; rats; lean mice; ob ob mice; leptin; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Oscillations in cytoplasmic Ca2+ concentration ([Ca2+]i) is the key signal in glucose-stimulated β-cells governing pulsatile insulin release. The glucose response of mouse β-cells is often manifested as slow oscillations and rapid transients of [Ca2+] i. READ MORE

  4. 2. Studies of cAMP and Ca2+ signaling in pancreatic islet cells

    Author : Hongyan Shuai; Anders Tengholm; Erik Gylfe; Sebastian Barg; Albert Salehi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic islet; insulin; glucagon; somatostatin; pancreatic polypeptide; exendin- 9-39 ; GLP-1; GIP; ATP; adenosine; cAMP; Ca2 ; β-cell; α-cell; δ-cell; PP-cell;

    Abstract : The blood glucose-lowering and -elevating hormones insulin and glucagon are released from the pancreatic islet β- and α-cells, respectively. The intracellular messengers Ca2+ and cAMP have central roles in controlling the secretion of both hormones, but the underlying mechanisms are incompletely understood. READ MORE

  5. 3. New proteins in Ca2+ regulation : parathyroid hormone-related protein and a Ca2+ sensor molecule

    Author : Per Hellman; Uppsala universitet; []

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

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

    Abstract : 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. READ MORE
