  2. 6. A Bioinformatics Study of Human Transcriptional Regulation

    Author : Adam Ameur; Jan Komorowski; Claes Wadelius; Philipp Bucher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; microarray; ChIP-chip; ChIP-seq; transcription factor; histone modification; motif search; Bioinformatics; Bioinformatik;

    Abstract : Regulation of transcription is a central mechanism in all living cells that now can be investigated with high-throughput technologies. Data produced from such experiments give new insights to how transcription factors (TFs) coordinate the gene transcription and thereby regulate the amounts of proteins produced. READ MORE

  4. 7. Rule-based Models of Transcriptional Regulation and Complex Diseases : Applications and Development

    Author : Susanne Bornelöv; Jan Komorowski; Claes Wadelius; Joanna Polanska; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Histone modification; Transcription factor; Transcriptional regulation; Next-generation sequencing; Feature selection; Machine learning; Rule-based classification; Asthma; Allergy; Bioinformatik; Bioinformatics;

    Abstract : As we gain increased understanding of genetic disorders and gene regulation more focus has turned towards complex interactions. Combinations of genes or gene and environmental factors have been suggested to explain the missing heritability behind complex diseases. READ MORE

  5. 8. Non-protein-coding RNA : Transcription and regulation of ribosomal RNA

    Author : Stefanie Böhm; Ann-Kristin Östlund Farrants; Brian McStay; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ribosomal RNA; non-coding RNA; ribosomal genes; rDNA gene; B-WICH; chromatin remodelling; histone modification; Cell Biology; cellbiologi;

    Abstract : Cell growth and proliferation are processes in the cell that must be tightly regulated. Transcription of ribosomal RNA and ribosomal biogenesis are directly linked to cell growth and proliferation, since the ribosomal RNA encodes for the majority of transcription in a cell and ribosomal biogenesis influences directly the number of proteins that are synthesized.

  6. 9. Characterization of Gcn5 histone acetyltransferase in Schizosaccharomyces pombe

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

    Abstract : 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. READ MORE

  7. 10. Genome-wide patterns of histone modifications in fission yeast

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

    Abstract : 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. READ MORE
