  1. 1. Histone deacetylases and their co-regulators in schizosaccharomyces pombe

    Författare :Rebecka A. Silverstein; Karl Ekwall; Anthony Wright; Fred Van Leeuwen; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The DNA in every eukaryotic cell is wrapped around eight core histones to form the nucleosome. Therefore all events that involve DNA must also involve chromatin and nucleosomes. By regulating chromatin structure the cell can regulate the reactivity of the DNA. LÄS MER

  3. 2. On histone deacetylases in the epigenetic regulation of neural stem and cancer cell fate

    Författare :Karolina Wallenborg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Development of an organism requires correct spatial and temporal regulation of gene expression. Epigenetic regulation of gene expression has been shown to be an important part of many cellular events. Nucleosomes consist of two subunits of each core histone proteins H2A, H2B, H3, H4, and 146 base pairs of DNA, wrapped around the histones. LÄS MER

  4. 3. Characterization of Gcn5 histone acetyltransferase in Schizosaccharomyces pombe

    Författare :Anna Johnsson; Anthony Wright; Mattias Mannervik; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The organisation of eukaryotic DNA into chromatin provides a natural barrier that prevents full access to the DNA thereby inhibiting events such as transcription, replication and repair. In order for these DNA-related events to occur, the chromatin needs to be modified by chromatin remodelling or, by reversible post-translational modifications. LÄS MER

  5. 4. Genome-wide patterns of histone modifications in fission yeast

    Författare :Indranil Sinha; Karl Ekwall; Karin Dahlman-Wright; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : DNA is wrapped almost two times around a group of proteins called histones to form a chromosomal structure known as the nucleosome. Both DNA and histones can be modified with different chemical tags by several enzymes to activate or suppress a particular gene or group of genes. Histones can be covalently modified at several places. LÄS MER

  7. 5. The IGF-axis in liver disease : modulation of expression by histone deacetylase inhibitors

    Författare :Steven Gray; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Liver Tumor; Histone Aceltylation; Gene expression; trichostatin A; Insulin-like growth factor axis; Comparative genomic hybridization; Spectral karyotyping;

    Sammanfattning : The Insulin-like growth factor (IGF) axis is composed of a family of ligands, receptors and binding proteins with important functions in the regulation of cell growth, apoptosis, survival, migration and development. The liver is a major provider of several of the IGF-axis members. LÄS MER
