1. 1. Synthesis of Novel Homoserine Analogues - Towards t he Development of Substrate-based Peptide Inhibitors of cAMP-dependent Protein Kinase

   Författare :Anna-Carin Carlsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein kinases; protein kinase inhibitors; substrate-based kinase inhibitors; cAMP-dependent protein kinase; kemptide; homoserine; asymmetric -amino acid synthesis; glycine -anion equivalents; Schöllkopf’s bislactim ether; epoxidation; nucleophilic epoxide ring opening; microwave-assisted synthesis;

   Sammanfattning : Protein kinases are enzymes that via phosphorylation of proteins/peptides regulate most aspects of cell functions and physiology. The enzymes transfer a -phosphoryl group from ATP to hydroxyl groups of Ser, Thr and Tyr residues in their substrates. LÄS MER

3. 2. Beta-amyloid, tau-protein and cystatin C in the pathophysiology of Alzheimer´s disease

   Författare :Maj-Linda Selenica; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsykologi; neurofysiologi; neuropsychology; neurophysiology; Neurology; Medicine human and vertebrates ; Medicin människa och djur ; Clinical chemistry; Klinisk kemi; Kinase inhibitors; Tau protein; Cystatin C; Glycogen Synthase Kinase; Alzheimers Disease; Amyloid beta;

   Sammanfattning : Alzheimer´s Disease (AD) is a progressive neurodegenerative dementia characterized by the extracellular accumulation of the beta-amyloid (Ab) peptide into plaques and intracellular phosphorylation and accumulation of tau protein into neurofibrillary tangles (NFT). Inflammation due to astrocytic and microglial activation is one of the ongoing processes in the disease giving rise to cytokine production and oxidative stress. LÄS MER

4. 3. Adipocyte phosphatases and the antilipolytic action of insulin

   Författare :Svante Resjö; Signaltransduktionsforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein phosphorylation; protein purification; adipose tissue; PP2A; protein phosphatase; PDE3B; phosphodiesterase 3B; Insulin signalling; antilipolysis; Klinisk biologi; Clinical biology; PKB; protein kinase B;

   Sammanfattning : Adipose tissue is the main site of energy storage of the body and an important endocrine organ. Knowledge of the regulation of fat metabolism and the endocrine factors secreted by the adipocyte is crucial for the understanding of diseases such as obesity and diabetes. Insulin is the main antilipolytic hormone. LÄS MER

5. 4. Protein Kinase Inhibition in Late Cerebral Ischemia after Subarachnoid Hemorrhage

   Författare :Saema Ansar; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; protein kinase; cerebral ischemia; subarachnoid hemorrage; neurofysiologi; neuropsykologi;

   Sammanfattning : The cerebral ischemia that occur after a subarachnoid hemorrhage (SAH) often results in death or severe disability and is a significant cause of stroke. Our hypothesis is that cerebral ischemia leads to pathophysiological receptor changes on the vascular smooth muscle cells. LÄS MER

7. 5. Studies on the Differential Specificity of Protein Kinases and Its Applications

   Författare :Mart Loog; Bengt Jergil; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Protein kinases; protein kinase inhibitors; substrate specificity; peptide libraries; affinity chromatography; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : Protein kinases are enzymes that catalyse the phosphoryl transfer from the g-phosphate of ATP to acceptor amino acids in proteins. The specificity of selected model protein kinases was studied at three different levels using a) novel bi-substrate-analogue inhibitors, b) synthetic peptide substrates and c) mutated protein substrate analogues.
