  1. 1. Identification of novel BRCA2-binding proteins that are essential for meiotic homologous recombination

    Author : Jingjing Zhang; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; meiosis; DSB; cancer; BRCA2; MEILB2; BRME1; HR; RAD51; DMC1; DDR;

    Abstract : Meiotic recombination is a molecular process in which the induction and repair of programmed DNA double-strand breaks (DSBs) creates genetic exchange between homologous chromosomes and thus increases genetic diversity and ensures chromosome segregation. Breast cancer susceptibility gene 2 (BRCA2) is a potent cancer suppressor and is required for DSB repair by homologous recombination (HR) in mitosis. READ MORE

  2. 2. Replication Dynamics in the DNA Damage Response

    Author : Petra Groth; Thomas Helleday; Geroge Iliakis; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA replication; homologous recombination; DNA double strand-breaks; ionizing radiation; alkylating agents; NATURAL SCIENCES; NATURVETENSKAP; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Abstract : Faithful DNA replication is essential and the induction of replication stress may have profound effects on genomic integrity. This is demonstrated by the formation of DNA double strand breaks (DSBs), considered to be the most toxic DNA lesions, at stalled replication forks. READ MORE

  3. 3. Nanofluidics for Static and Dynamic DNA-Protein Interaction Studies - Repair of Double-Strand Breaks from a Single-Molecule Perspective

    Author : Robin Öz; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Single-molecule; Protein; NHEJ; Dynamic; DNA repair; HR; Biomolecule interactions; Microscopy; Fluorescence; Nanofluidics;

    Abstract : Double-strand breaks (DSBs) is one of the most lethal forms of DNA damage. A single DSB may result in stalling of vital cellular machineries, and thus, requires immediate measures by the cell. READ MORE

  4. 4. Genomic rearrangements at the cause of three genetic disorders in man

    Author : Kristina Lagerstedt; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Mucopolysaccharidosis type II MPS II ; The Hunter syndrome; Incontinentia pigmenti IP ; Blepharophimosis; ptosis; epicanthus inversus syndrome BPES ; mutational analysis; nonhomologous end joining NHEJ ; homologous recombination HR ; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Abstract : Genomic rearrangements are a common cause of genetic disorders in man. This thesis describes the analysis of genomic rearrangements observed in patients with the Hunter syndrome (MPS II), incontinentia pigmenti (IP) and the Blepharophimosis, ptosis and epicanthus inversus syndrome (BPES). MPS II is an X-linked recessive lysosomal storage disorder. READ MORE

  5. 5. Transcription Associated Recombination in Mammalian Cells

    Author : Linda Savolainen; Thomas Helleday; Andres Aguilera; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Biology; Biologi; molekylärgenetik; Molecular Genetics;

    Abstract : There is increasing evidence that the movement of the transcription machinery through DNA has profound effects on the genomic stability. One such example is a phenomenon known as Transcription Associated Recombination (TAR). Transcription enhances recombination levels to a high degree in all organisms studied, from bacteria to mammals. READ MORE
