  4. 3. Interactions Between Small Heat Shock Proteins and Substrate Proteins Mass Spectrometric Detection of Crosslinked Peptides to Map Protein-Protein Interactions

    Författare :Emma Åhrman; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein-protein interactions; Small heat shock proteins; Mass spectrometric peptide mapping; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. LÄS MER

  5. 4. Mass Spectrometric Applications for Diagnosing Metabolic and Endocrine Diseases

    Författare :Mark M. Kushnir; Jonas Bergquist; Alan L Rockwood; David Herold; Uppsala universitet; []
    Nyckelord :Analytical chemistry; biomarker; liquid chromatography; tandem mass spectrometry; LC-MS MS; sample preparation; isomers; steroid hormones; congenital adrenal hyperplasia; polycystic ovary syndrome; Analytisk kemi;

    Sammanfattning : Disease-specific compounds (biomarkers) are analyzed in clinical laboratories to assist with diagnosing diseases. This thesis describes development and validation of liquid chromatography tandem mass spectrometry (LC-MS/MS) based tests for diagnosing a diverse group of endocrine and metabolic diseases. LÄS MER

  7. 5. Mass spectrometric investigation of protein nitration in inflammation and neurodegeneration

    Författare :Henrik Ryberg; Göteborgs universitet; []
    Nyckelord :mass spectrometry; oxidative stress; nitrotyrosine; neurodegeneration; peroxynitrite; protein modification;

    Sammanfattning : The nitration of tyrosine seems to be very common in human diseases and at least forty different diseases have been reported to be associated with an increased nitration of proteins. The nitration of proteins results in a modification of tyrosine, 3-nitrotyrosine (3-NT), which is stable. LÄS MER
