  1. 1. The Ecophysiology of Arbuscular Mycorrhizal Fungi: Phosphatase Activity Associated with Extraradical and Intraradical Mycelium

    Författare :Ingrid van Aarle; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Scutellospora; polyphosphate; phosphorus uptake; phosphorus transfer; phosphatase; pH; mycelium; Glomus; fatty acid; Gigaspora; arbuscular mycorrhiza; ELF;

    Sammanfattning : Arbuscular mycorrhizal (AM) fungi colonise a wide range of plant species and are especially common in soils with a relatively high pH, where phosphorus availability is a limiting factor for primary production. The aim of this thesis was to study the ecophysiology of arbuscular mycorrhizal (AM) fungi when exposed to different environments. LÄS MER

  2. 2. Tartrate resistant acid phosphatase in the immune and nervous system : distribution and pathophysiological implications

    Författare :Pernilla Lång; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tartrate resistant acid phosphatase (TRAP) belongs to the family of purple acid phosphatases (PAP). It is a glycoprotein synthesized as a monomer with low enzyme activity containing a redox active diiron centre in the active site. Post-translational proteolytic processing of this monomer into a dimeric protein increases the enzyme activity. LÄS MER

  3. 3. Regulation of Na+,K+-ATPase activity by protein phosphatase-1 and protein kinase C : studies in infant and adult renal tissue and on vascular smooth muscle cells

    Författare :Dailin Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Na ; K -ATPase; phosphorylation; protein kinase C; protein phosphatase-1; arachidonic acid metabolites; ontogeny;

    Sammanfattning : Na+, K+-ATPase is short-term modulated by hormones, involving activation of signal transduction system. The present study was designed to elucidate the role of the signaling molecules PP-1, PKC and arachidonic acid (AA) metabolites in the regulation of Na+, K+-ATPase by reversible phosphorylation, the final step of the signal transduction, and to examine the ontogeny of the signaling system.

  4. 4. Protein phosphorylation cascades regulating islet beta-cell insulin exocytosis through glucose sensing and drug signaling : with special focus on serine/threonine protein phosphates and hypoglycemic sulfonylureas

    Författare :Mikael Lehtihet; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diabetes; Islet; Insulin; Exocytosis; Protein phosphatase; Protein kinase; CPT-1; Sulfonylurea; Glutamate; Polyphosphoinositide;

    Sammanfattning : In human type 2 diabetes, loss of glucose-sensitive insulin secretion from the pancreatic �-cell is an early pathogenetic event. Initially, this may be compensated for by stimulating insulin secretion by sulfonylurea drugs. LÄS MER

  5. 5. Molecular mechanisms of estrogen action in relation to metabolic disease

    Författare :Lovisa Lundholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Estrogens have multiple effects on the body. Most studied are the effects on female reproduction. In this thesis, we have focused on the metabolic effects of estrogens. Estrogen treatment decreases adipose tissue mass and has anti-diabetic effects in humans and mice. LÄS MER
