  1. 1. Accessory factors for ribosomal assembly

    Författare :Mattias Lövgren; Mikael Wikström; Dan Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; RimM; RbfA; RlmB; ribosomal assembly; rRNA processing; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The assembly of ribosomal RNA (rRNA) and ribosomal proteins (r-proteins) into ribosomal subunits (30S and 50S) is a complex process. Transcription of rRNA requires antitermination proteins and the primary transcripts are processed by ribonucleases. LÄS MER

  3. 2. Modified Glycopeptides Targeting Rheumatoid Arthritis : Exploring molecular interactions in class II MHC/glycopeptide/T-cell receptor complexes

    Författare :Ida E. Andersson; Jan Kihlberg; Anna Linusson Jonsson; Craig Crews; Umeå universitet; []

    Sammanfattning : Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that leads to degradation of cartilage and bone mainly in peripheral joints. In collagen-induced arthritis (CIA), a mouse model for RA, activation of autoimmune CD4+ T cells depends on a molecular recognition system where T-cell receptors (TCRs) recognize a complex between the class II MHC Aq protein and CII259-273, a glycopeptide epitope from type II collagen (CII).

  4. 3. Removal and Replacement of Ribosomal Proteins : Effects on Bacterial Fitness and Ribosome Function

    Författare :Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; Microbiology; Mikrobiologi; Biochemistry; Biokemi; Mikrobiologi; Microbiology;

    Sammanfattning : Protein synthesis is a complex process performed by sophisticated cellular particles known as ribosomes. Although RNA constitutes the major structural and functional component, ribosomes from all kingdoms contain an extensive array of proteins with largely undefined functional roles. LÄS MER

  5. 4. Transcriptional profiling of human embryonic stem cells and their functional derivatives

    Författare :Jane Synnergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcription; differentiation; human embryonic stem cells; gene expression; Naturvetenskap;

    Sammanfattning : Human embryonic stem cells (hESCs) represent populations of pluripotent, undifferentiated cells with unlimited replication capacity, and with the ability to differentiate into any functional cell type in the human body. Based on these properties, hESCs and their derivatives provide unique model systems for basic research on embryonic development. LÄS MER

  7. 5. Joint disease biomarkers - discovery and application

    Författare :Dovilė Sinkevičiūtė; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; Psoriatic arthritis; cartilage; Proteomics; Biomarkers; ELISA; Tissue culture; Extracellular matrix ECM ;

    Sammanfattning : Dysregulated cartilage homeostasis, articular cartilage degradation and abnormal bone remodeling are common denominators in joint disease and can lead to severe disability for the patients. The molecular pathways behind the disease pathology can overlap across different joint diseases. LÄS MER
