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

    University dissertation from Stockholm : Wenner-Grens institut för experimentell biologi

    Author : Tobias Lilja; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transcription; Co-regulator; Development; Drosophila; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi 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. Molecular mechanisms of transcriptional repression by the orphan receptor SHP

    University dissertation from Stockholm : Karolinska Institutet, Biosciences and Nutrition

    Author : Ann Båvner; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear receptor; repression; small heterodimer partner; co-regulator;

    Abstract : SHP (Small Heterodimer Partner) is an atypical orphan member of the mammalian nuclear receptor family that consists of only a putative ligand-binding domain and thus cannot bind DNA. The aim of this thesis was to investigate the molecular mechanisms of the transcriptionally inhibitory effect of SHP. READ MORE

  3. 3. DNA microarray approaches to understanding the regulation and evolution of gene expression networks

    University dissertation from Stockholm : Karolinska Institutet

    Author : Yongtao Xue-Franzen; Yongtao Xue-Franzén; Södertörns högskola.; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : DNA microarray technology allows biological and medical research to shift from investigation of individual functions of a few related genes to the whole genome level. This creates opportunities for discovery of complex and coordinated transcriptional networks in biological systems. READ MORE

  4. 4. Structure and function of the yeast mediator tail domain

    University dissertation from Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Author : Jenny Béve; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transcription; RNA polymerase II; Co-activator; Mediator; Tail- module;

    Abstract : Mediator is a co-regulator complex that transduces regulatory information from activators and repressors to the RNA polymerase 11 transcription machinery. Mediator was originally discovered in Saccharomyces cerevisiae and since then Mediator-like complexes have been isolated in a number of organisms including mammals. S. READ MORE

  5. 5. Histone deacetylases and their co-regulators in Schizosaccharomyces pombe

    University dissertation from Stockholm : Karolinska Institutet, Biosciences and Nutrition

    Author : Rebecca Ann Silverstein; Karolinska Institutet.; Karolinska Institutet.; Södertörns högskola.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    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
