  2. 1. Oxidative damage and the DNA glycosylase MutYH

    Author : Kristina Jansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oxidative damage; 8-oxo-7; 8-dihydro-2′-deoxyguanosine; Base excision repair; DNA glycosylase; Mismatch repair; DNA damage checkpoint; 9-1-1 complex; Glutathione-S-transferases; Colon cancer.;

    Abstract : The DNA glycosylase MutYH is highly conserved throughout evolution, and homologs are found in most eukaryotes and prokaryotes examined. MutYH functions as a base excision repair DNA glycosylase that excises adenines misincorporated opposite 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG), one of the most stable products of oxidative DNA damage.

  4. 2. DNA damage affecting thyroidal iodide transport: an explanation to thyroid stunning

    Author : Madeleine Nordén; Göteborgs universitet; []
    Keywords : thyroid; radioiodide; thyroid stunning; NIS; cell cycle; genotoxic stress; DNA damage; H2AX; ATM;

    Abstract : 131I is widely used clinically in the treatment of Graves´ disease and differentiated thyroid cancer. However, cellular and molecular effects of 131I irradiation in relation to absorbed dose are poorly documented. READ MORE

  5. 3. Response mechanisms of normal hematopoietic cells and leukemic cells to genotoxic agents and novel therapeutic strategies

    Author : Andreas Hedblom; Malmö Experimentell cancerforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cells; genotoxic damage; cell cycle; leukemia; heme oxygenase; differentiation;

    Abstract : Hematopoiesis is initiated by a rare population of hematopoietic stem cells (HSC) in the bone marrow (BM). HSCs give rise to red blood cells and white blood cells of myeloid and lymphoid lineages. READ MORE

  6. 4. Systematic Modular Approaches to Reveal DNA Damage Responses in Mammalian Cells

    Author : J. Peter Svensson; Ingela Turesson; Jean Bourhis; Uppsala universitet; []
    Keywords : Molecular biology; gene expression profiling; DNA damage; network; cancer; ionizing radiation; cisplatin; Molekylärbiologi;

    Abstract : Cancer therapy operates by inflicting damage in malignant cells. The most lethal target is the genomic DNA. As a single double strand DNA break has the potential to kill the cell, mechanisms have evolved to detect and block propagation of the damage. READ MORE

  7. 5. Chemically Induced DNA Damage in Extended-term Cultures of Human Lymphocytes

    Author : Maria Andersson; Björn Hellman; Leif Busk; Uppsala universitet; []
    Keywords : Toxicology; Comet assay; DNA-damaging agents; DNA repair; Extended-term Cultures of Human Lymphocytes; Genotoxicity; Induced DNA damage; In vitro; Mouse Lymphoma Cells; Primary Cell Cultures; Reactive Oxygen Species; Toxikologi;

    Abstract : Generation of DNA damage is regarded to be an important initial event in the development cancer. Consequently, a battery of tests have been developed to detect different types of genotoxic effects in order to be able to predict the potential genotoxicity and mutagenicity of chemicals, including both pharmaceutical drugs and various types of environmental and occupational agents, as well as dietary factors.
