  1. 1. Investigating the activation and regulation of the proteasome : an essential proteolytic complex

    Författare :Patrick Masson; Patrick Young; Marcus Groettrup; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteasome; PA28gamma; Transcriptional regulation; Drosophila; 26S; Molecular biology; Molekylärbiologi;

    Sammanfattning : The proteasome is a major non-lysosomal proteolytic complex present in eukaryotic cells and has a central role in regulating many protein levels. The complex has been shown to participate in various intracellular pathways including cell cycle regulation or quality control of newly synthesized proteins and many other key pathways. LÄS MER

  3. 2. Nanoscopic adventures : unraveling macromolecular complexes in infectious diseases via integrative structural biology

    Författare :Kai Patric Ehrenbolger; Ronnie Berntsson; Felipe Cava; Jonas Barandun; David Drew; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infectious diseases; E. faecalis; Microsporidia; Ribosome; Proteasome; Polar Tube; Structural Biology; Single particle Cryo-Electron Microscopy;

    Sammanfattning : This thesis focuses on understanding the underlying molecular mechanisms of infectious diseases, which claim nearly 9 million lives annually. The research centers on critical analysis of pathogen mechanisms and drug resistance. I have mainly focused on two clades of pathogens: Enterococcus faecalis and microsporidia. E. LÄS MER

  4. 3. Embryonic Stem Cells: Differentiation into Insulin Producing Cells and Elimination of Damaged Proteins

    Författare :Gabriella Brolén; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; oxidatively damaged proteins; diabetes; carbonyl; C-peptide; Medicine human and vertebrates ; insulin; human embryonic stem cell; 20S proteasome; AGE; Pdx1; proinsulin;

    Sammanfattning : This thesis includes two different parts: One focusing on how to induce human embryonic stem cells (hESCs) to differentiate into insulin producing cells by following the normal pancreatic development pathway. These cells have then the potential to be an unlimited source for diabetes regenerative medicine. LÄS MER

  5. 4. Studies of metazoan proteasome function and regulation

    Författare :Josefin Lundgren; Patrick Young; Michael Glickman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteasome ubiquitin RNAi microarray; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Biological processes depend upon the structural and functional quality of the molecules that comprise living organisms. The integrity of molecules such as DNA, RNA, proteins, carbohydrates and lipids is crucial and the precise three-dimensional shape and the detailed chemistry of these molecules orchestrate the biochemical processes vital for life.

  7. 5. Proteasome Inhibitors against Cancer: Determining Biology and Finding Novel Compounds

    Författare :Arjan Mofers; Stig Linder; Padraig D´arcy; Sonia Lain; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cancer continues to be a tremendous burden on society in terms of loss of quality of life and life-years. The ubiquitin proteasome system (UPS), responsible for the bulk of protein turnover in the cell, is considered an attractive target in cancer therapy. LÄS MER
