  3. 7. Calcium transporting ATPases in plant cells

    Författare :Malin Olbe; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Triticum aestivum; calcium; Brij 58; calmodulin; Ca2 signalling; inside-out; endoplasmic reticulum; plant; plasma membrane; proteolysis; P-type ATPase; spinach; Spinacea oleracea; trypsin; two-phase; wheat.; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes.

  4. 8. 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

  5. 9. Activation and Regulation of TRPV1 : Studies in Recombinant Human Neuroblastoma TRPV1-SHSY5Y Cells

    Författare :Johanna EL Andaloussi-Lilja; Anna Forsby; Antonio Ferrer-Montiel; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nociception; neurotrophic factors; eye irritation; stable transfection; Ca2 ; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : TRPV1 is a transmembrane non-selective cation channel with preference for Ca2+. The receptor is primarily localised on dorsal root ganglion neurons and is activated by numerous endogenous and exogenous potentially irritating ligands eliciting pain. LÄS MER

  7. 10. On Cholecystokinin and Phospholipase A2 in Insulin Secretion - an Experimental Study With Reference to the Development of Diabetes

    Författare :Erik Simonsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Insulin Resistance; Islet; Beta-cell; Insulin Secretion; Ca2 -Dependency; Intracellular Signalling; Phospholipase A2; Cholecystokinin; Non-glucose Secretagogues; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : In view of unsolved issues regarding cellular events underlying the adaptation of insulin secretion to insulin resistance, together with the observation that insulin secretion induced by the gastrointestinal hormone and neuropeptide cholecystokinin (CCK) is not solely explained by phospholipase C-protein kinase C (PLC-PKC) pathway activation, this study aimed at delineate mechanisms responsible for the hyperinsulinemia in insulin resistance, with particular attention paid to the action of glucose vs. non-glucose secretagogues, such as CCK.
