  2. 1. Signal transduction via ion fluxes : a cell imaging study with emphasis on calcium oscillations

    Author : Per Uhlén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Calcium; Ca2 signalling; Ca2 oscillation; InsP3; InsP3 receptor; Na; K-ATPase; ouabain; physical interaction; FRET; spectral analysis; confocal microscopy;

    Abstract : Signal transduction via ion fluxes is of vital importance for all mammalian cells. Cells can exploit ion regulatory mechanisms to generate and transmit intracellular signals. Improvements in digital microscopic imaging technology have made it possible to explore micro-environments and complex intracellular machineries. READ MORE

  4. 2. Factors Influencing Phytate Degradation in Piglets. Feed phytate behaviour and degradation by microbial phytases

    Author : Katrine Pontoppidan; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pigs; in vitro digestion; P. lycii; inositol phosphates; phytate; phytase;

    Abstract : Phytate, the main storage form of phosphorus (P) in plant feedstuffs, is indigestible for monogastric animals, and phytases are therefore used as feed additives to increase the digestibility of phytate-P and limit the inclusion of inorganic P. However, new and improved phytases are needed to obtain better phytate digestibility and allow for lower inclusions of inorganic P. READ MORE

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

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

    Abstract : 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. READ MORE
