  1. 1. Functions of Transcriptional Co-regulators in Drosophila development

    Author : Tobias Lilja; Mattias Mannervik; Ze'ev Paroush; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Transcription; Co-regulator; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : During Drosophila development, regulation of gene expression through interplay between transcriptional activators and repressors is generating complex patterns of gene expression that leads to cell differentiation. For proper control of transcription, transcription factors bind to DNA at control regions, so called Cis Regulatory Modules (CRM). READ MORE

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

    Author : Rebecka A. Silverstein; Karl Ekwall; Anthony Wright; Fred Van Leeuwen; Rebecca Ann Silverstein; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : 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. READ MORE

  3. 3. Regulators of chromatin and transcription in Drosophila

    Author : Filip Crona; Mattias Mannervik; Fernando Azorin; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Transcription; chromatin; co-regulators; CBP; lysine demethylase; KDM4A; Brakeless; Drosophila; utvecklingsbiologi; Developmental Biology;

    Abstract : Development of multicellular organisms is achieved by organized temporal and spatial patterns of gene expression leading to cell differentiation. Chromatin regulators control how the DNA is utilized by altering access of proteins to DNA and thereby function as co-factors in transcription. READ MORE

  4. 4. The hematopoietic transcription factor RUNX1 : a structural view

    Author : Stefan Bäckström; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; RUNX1; Runt domain; CBFβ; transcription factor; leukaemia; protein crystallography; anomalous diffraction; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylärbiologi; Molecular Biology;

    Abstract : The malfunction of the transcriptional regulator RUNX1 is the major cause of several variants of acute human leukemias and its normal function is to regulate the development of the blood system in concert with other transcriptional co-regulators. RUNX1 belongs to a conserved family of heterodimeric transcription factors that share a conserved DNA binding domain, the Runt domain (RD), named after the first member of this group – Runt - found in Drosophila melanogaster.

  5. 5. Gut microbial regulation of bile acid metabolism and signaling

    Author : Sama I. Sayin; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Medicine; Gut Microbiota; Bile Acids;

    Abstract : The collection of microbes in our gastrointestinal tract, the gut microbiota, is an environmental factor that has profound impact on host health and disease. Bile acids are endogenous cholesterol-derived molecules that can be modified by the gut microbiota and function as signaling molecules in regulation of host metabolic processes. READ MORE
