  2. 1. Nucleolar Ribosome Assembly

    Author : Fredrik Lackmann; Lars Wieslander; Denis Lafontaine; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome biogenesis; RNA; Nucleolus; Molecular Biology; molekylärbiologi;

    Abstract : Ribosomes are macromolecular machines that are responsible for production of every protein in a living cell. Yet we do not know the details about how these machines are formed. The ribosome consists of four RNA strands and roughly 80 proteins that associate with each other in the nucleolus and form pre-ribosomal complexes. READ MORE

  4. 2. Eukaryotic Ribosome Biogenesis : Focus on the function of the assembly factor Mrd1p

    Author : Åsa Segerstolpe; Lars Wieslander; Susan Gerbi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome biogenesis; nucleolus; pre-rRNA processing; RNA-binding proteins; Mrd1; Molecular Biology; molekylärbiologi;

    Abstract : The ribosome, the protein factory of the cell, is essential for all life forms. The ribosome is a large RNA-protein machine. It is built in a complex, multi-step process that involves a large number of accessory trans-acting factors and the synthesis consumes a considerable part of the cellular energy. READ MORE

  5. 3. The spatiotemporal protein landscape of human cells

    Author : Lovisa Stenström; Emma Lundberg; Björn Högberg; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Spatial proteomics; Immunofluorescence; Human Protein Atlas; Nucleolus; Cell cycle; Citizen science; Bioteknologi; Biotechnology;

    Abstract : This thesis focuses on the spatiotemporal mapping of proteins at a subcellular level. In other words, determining the cellular location of proteins over time. From a biological point of view, knowledge about protein location is fundamental to understand protein function. READ MORE

  6. 4. The interactome of the Epstein-Barr virus nuclear antigen 5 suggests novel roles in RNA and protein metabolism

    Author : Josefine Ekholm; Göteborgs universitet; []
    Keywords : Epstein-Barr virus; EBNA5; chaperone; proteasome; nucleolus;

    Abstract : Epstein-Barr virus (EBV) is a human herpes virus that infects B and epithelial cells of the oropharynx. EBV is transmitted by saliva and establishes a lifelong latency in over 90% of the world's population. During latency, the virus exists predominantly as multicopy episomes in the nuclei of memory B cells. READ MORE

  7. 5. Diamond-Blackfan Anemia: Erythropoiesis Lost in Translation

    Author : Johan Flygare; Stefan Karlsson; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Hematologi; Haematology; RNA interference; Erythropoiesis; Lentiviral vectors; Nucleolus; Diamond-Blackfan anemia; Gene therapy; extracellulära vätskor;

    Abstract : Diamond-Blackfan anemia (DBA) is a congenital erythroid aplasia that usually presents as macrocytic anemia during infancy. Linkage analysis suggests that at least four genes are associated with DBA of which two have been identified so far. READ MORE
