  1. 1. Growth and Behaviour Epigenetic and Genetic Factors Involved in Hybrid Dysgenesis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Wei Shi; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Interspecies hybridization; hybrid dysgenesis effect; speciation; genomic imprinting; epigenetics; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi;

    Abstract : In mammals, the most frequently observed hybrid dysgenesis effects are growth disturbances and male sterility. Profound defects in placental development have been described and our work on hybrids in genus Mus has demonstrated putative hybrid dysgenesis effects that lead to defects in lipid homeostasis and maternal behavior.

  2. 2. CTCF and Epigenetic Regulation of the H19/Igf2 Locus

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Vinod Pant; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Imprinting; Chromatin; H19; Igf2; CTCF; Insulator; methylation; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi;

    Abstract : An overall coordination between the expressions of genes is required for the proper development of an individual. Although most genes are expressed from both the constituent alleles of the genome, a small subset of autosomal genes are preferentially expressed from only one of the parental alleles, a phenomenon known as genomic imprinting.

  3. 3. 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

  4. 4. Epigenetic Control of Mammalian Development : Studies on an imprinting control region

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Liang Liu; Pärt Peterson; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Epigenetic; Genomic imprinting; DNA methylation; Igf2; H19; Insulator; CTCF; Imprinting control region; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; zoologisk utvecklingsbiologi; Animal Development;

    Abstract : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. READ MORE

  5. 5. Gene expression and its physiological control in disease and development Studies on the human PDGF-B gene and tumour hypoxia

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Ullerås; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Zoologisk utvecklingsbiologi; Animal Development;

    Abstract : Strict control of gene expression is essential during development and in response to physiological stimuli. This thesis describes the functional characterisation of the gene regulatory mechanisms controlling the expression of the potent human growth factor Platelet Derived Growth Factor B gene, in a cell type specific context and in response to low oxygen tension.
