  2. 1. The Multifunctional HnRNP A1 Protein in the Regulation of the Cyp2a5 Gene : Connecting Transcriptional and Posttranscriptional Processes

    Author : Tina Glisovic; Matti Lang; Francoise Raffalli-Mathieu; Lorenz Poellinger; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; Cyp2a5; DNA-protein interaction; gene regulation; hnRNP A1; nucleocytoplasmic shuttling; RNA-protein interaction; RNA stabilization; posttranscriptional; transcriptional; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi;

    Abstract : The mouse xenobiotic-inducible Cyp2a5 gene is both transcriptionally and posttranscriptionally regulated. One of the most potent Cyp2a5 inducers, the hepatotoxin pyrazole, increases the CYP2A5 mRNA half-life. READ MORE

  4. 2. Cyanobacterial Hydrogen Metabolism : Regulation and Maturation of Hydrogenases

    Author : Ellenor Devine; Peter Lindblad; Karin Stensjö; Laurent Cournac; Uppsala universitet; []

    Abstract : In times with elevated CO2 levels and global warming there is a need of finding alternatives to carbon based energy carriers. One such environmental friendly solution could be H2 produced by living organisms. READ MORE

  5. 3. An analytical framework for studying transcriptional regulation

    Author : Christoph Sebastian Börlin; Chalmers University of Technology; []
    Keywords : transcription factor; ChIP-exo; S. cerevisiae; transcriptional regulation;

    Abstract : The state and behavior of any living cell is controlled by a complex interplay of different regulatory processes, with the regulation of transcription playing a major role. When a cell adapts to a new environment it often does that by modulating gene transcript levels, mainly through changes in transcription factor binding events. READ MORE

  6. 4. Decoding the Structural Layer of Transcriptional Regulation : Computational Analyses of Chromatin and Chromosomal Aberrations

    Author : Robin Andersson; Jan Komorowski; Jan Dumanski; Claes Wadelius; Anders Krogh; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Chromatin; Nucleosome positioning; Histone modifications; Chromosomal aberrations; Transcriptional regulation; Array-CGH; Next generation sequencing; ChIP-chip; Bioinformatics; Bioinformatik; Bioinformatics; Bioinformatik;

    Abstract : Gene activity is regulated at two separate layers. Through structural and chemical properties of DNA – the primary layer of encoding – local signatures may enable, or disable, the binding of proteins or complexes of them with regulatory potential to the DNA. READ MORE

  7. 5. Small RNAs, Big Consequences : Post-transcriptional Regulation and Adaptive Immunity in Bacteria

    Author : Mirthe Hoekzema; Gerhart E. H. Wagner; Magnus Lundgren; Kai Papenfort; Uppsala universitet; []

    Abstract : It is nowadays widely accepted that non-coding RNAs play important roles in post-transcriptional regulation of genes in all kingdoms of life. In bacteria, the largest group of RNA regulators are the small RNAs (sRNAs). READ MORE
