  1. 1. Transcriptional and epigenetic control of gene expression in embryo development

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Ann Boija; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epigenetics; Cell specification; Drosophila embryo; Dorsal morphogen; CBP p300; Gene regulation; Chromatin; Promoter proximal Pol II pausing; utvecklingsbiologi; Developmental Biology;

    Abstract : During cell specification, temporal and spatially restricted gene expression programs are set up, forming different cell types and ultimately a multicellular organism. In this thesis, we have studied the molecular mechanisms by which sequence specific transcription factors and coactivators regulate RNA polymerase II (Pol II) transcription to establish specific gene expression programs and what epigenetic patterns that follows.

  2. 2. Gene regulation during development by chromatin and the Super Elongation Complex

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Olle Dahlberg; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila development; gene regulation; transcription; chromatin; P-TEFb; Super Elongation Complex; KDM4A; H3K36me3; H3K14ac; histone replacement; utvecklingsbiologi; Developmental Biology;

    Abstract : Developmental processes are carefully controlled at the level of transcription to ensure that the fertilized egg develops into an adult organism. The mechanisms that controls transcription of protein-coding genes ultimately ensure that the Pol II machine synthesizes mRNA from the correct set of genes in every cell type. READ MORE

  3. 3. The Role of the Homeobox Gene ATHB16 in Development Regulation in Arabidopsis thaliana

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Yan Wang; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Arabidopsis thaliana; Homeobox gene; Functional genomics; Plant development; ATHB16; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Abstract : There are 42 members of the homeodomain-leucine zipper (HDZip) family of transcription factors in Arabidopsis thaliana. This thesis focuses on the functional analysis of one member of this family, ATHB16, and on the biochemical properties of HDZip proteins. READ MORE

  4. 4. Regulation of gene expression in fruit flies how does it start, and will it be remembered?

    University dissertation from Umeå : Umeå University, Department of Molecular Biology

    Author : Aman Zare; Umeå universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; epigenetics; transcription; gene regulation; transcription maintenance; CBP; polymerase pausing; Polycomb group proteins; transgenerational inheritance of transcriptional response; gut microbiome; molekylärbiologi; Molecular Biology;

    Abstract : One of the most distinctive features of eukaryotic chromosomes is the bundling of DNA together with functionally associated RNA and proteins in chromatin. This allows huge amounts of DNA to be packed inside the very tiny space of the nucleus, and alterations in the structure of chromatin enable access to the DNA for transcription (“reading” genes by production of RNA copies).

  5. 5. Epigenetic Regulation of Higher Order Chromatin Conformations and Gene Transcription

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anita Göndör; Uppsala universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Genomic imprinting; Chromatin; Epigenetics; Cancer; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi;

    Abstract : Epigenetic states constitute heritable features of the chromatin to regulate when, where and how genes are expressed in the developing conceptus. A special case of epigenetic regulation, genomic imprinting, is defined as parent of origin-dependent monoallelic expression. READ MORE
