  1. 21. Functional Characterization of the Yeast Tumour Suppressor Homologue Sro7p

    Författare :Annabelle Forsmark; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yeast; protein sorting; protein secretion; L 2 GL; tumour suppressor; SRO7; SRO77; ENA1; exocytosis; post-Golgi vesicles; ART5; E3 adaptor; ubiquitylation; ATLGL1; ATLGL2;

    Sammanfattning : Correct targeting of newly synthesized proteins to appropriate domains of the cell membrane is crucial to cellular architecture, polarity and function, making it no surprise that many proteins of the secretory machinery are conserved throughout evolution. This work presents a functional characterisation of the Saccharomyces cerevisiae cell polarity protein and tumour suppressor homologue, Sro7p. LÄS MER

  3. 22. Oxidative stress and proteolysis in the lens. Effects of anti-inflammatory drugs

    Författare :Anne Kling-Petersen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oxidation NSAIDs ASA dexamethasone apoptosis GSH GSSG proteasome lens epithelial cells mouse lens cataract;

    Sammanfattning : Oxidative stress has been implied in formation of age-related cataract. The objectives of this thesis were to study redox regulation of proteolysis and oxidative/antioxidative effects of anti-inflammatory substances in human lens epithelial cells (HLEC) and intact mouse lenses.

  4. 23. Membrane chaperones : protein folding in the ER membrane

    Författare :Jhansi Kota; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The plasma membrane (PM), comprised largely of lipids and proteins, is a dynamic structure that establishes the integrity of cells. Newly synthesized PM proteins are initially inserted into the endoplasmic reticulum (ER) prior to being targeted to the PM via the secretory pathway. Many PM proteins are polytopic, i.e. LÄS MER

  5. 24. Interplay between autophagy and amyloid beta metabolism in Alzheimer’s disease

    Författare :Richeng Jiang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer’s disease (AD), the most common neurodegenerative disease, is characterized by two pathological hallmarks: extracellular amyloid-beta peptide (Aβ) plaque depositions and neurofibrillary tangles (NFTs) composed of intracellular hyperphosphorylated tau aggregations. A cellular degradation system, autophagy is additionally dysfunctional in AD and plays a key role in Aβ and tau metabolisms. LÄS MER

  7. 25. Development of quantitative optical microscopy methods for single cell analysis

    Författare :Katarina Logg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein localization; quantitative optical microscopy; live cell imaging; image analysis; cellular stress;

    Sammanfattning : Optical microscopy has brought powerful methods to biological research, in particular the possibility to assay dynamic molecular processes within living individual cells. This thesis deals with various aspects of fluorescence and Raman microscopy, such as the possibility of avoiding cellular damage or stress caused by illumination, how to manipulate single cells for spectroscopic analysis and how to quantify images automatically.
