  1. 21. Mechanisms determining efficacy of tyrosine kinase-targeting anti-cancer drugs

    Författare :Maja Bradic Lindh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The expanding field of cancer research and the introduction of multiple molecular biology techniques have significantly improved cancer drug discovery, presented new drugs, including tyrosine kinase inhibitors, and thereby gave new hope to the cancer patients and their oncologists. Using this knowledge it is now becoming increasingly possible to determine outcome of malignant disease more accurately, to estimate response to specific therapies and to get closer to the ideal of personalized targeted therapy adjusted to each patient, and to the specific cancer type and its unique genetic profile.

  3. 22. Receptors for growth hormone and prolactin. Regulation and activation

    Författare :Gunnel Hellgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; GH receptor; Janus kinase; GH sensitivity; 5 -untranslated region; prolactin; prolactin receptor adipose tissue; liver; skeletal muscle; epidermal growth factor receptor; tyrosine kinase; kinase activity;

    Sammanfattning : Cytokine receptor activation is dependent on ligand-induced receptor dimerization or oligomerization and subsequent activation of several intracellular proteins. Activation of Janus kinases (Jaks) is probably the first intracellular event that occurs after receptor dimerization. LÄS MER

  4. 23. Protein Interactions Involving the Laminin G-type Domains of Vitamin K-dependent Protein S

    Författare :Petra Evenäs; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; tyrosine phosphorylation.; Sky receptor; SHBG-like region; protein S; G domain; Gas6; Activated protein C; C4b-binding protein; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The studies described in this thesis focus on the involvement of the two laminin G-type domains of vitamin K-dependent protein S in various biological contexts. The G-type domains are located in the C-terminal sex-hormone-binding globulin (SHBG)-like region. LÄS MER

  5. 24. Purine and Pyrazolopyrimidine Derivatives: Design and Synthesis of Chemical Tools for Biological Applications

    Författare :David Bliman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; purine; pyrazolopyrimidine; caged compounds; protein kinases; protein-protein interactions; fluorescence; organic synthesis;

    Sammanfattning : Purines can be found in a multitude of naturally occurring compounds with a range of functions. This thesis describes the design and synthesis of purines and structurally related pyrazolopyrimidine derivatives intended for biological applications. LÄS MER

  7. 25. Regulation and physiological role of tyrosine hydroxylase phosphorylation in the striatum

    Författare :Niklas Lindgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tyrosine hydroxylase (TH) catalyses the conversion of tyrosine to DOPA and is the rate- limiting enzyme in the biosynthesis of catecholamines, a group of neurotransmitters involved in various brain functions. Short-term regulation of TH activity is achieved by phosphorylation of the protein's regulatory domain at three seryl residues in positions 19, 31 and 40. LÄS MER
