  1. 16. Regulation of DNA damage responses by the Myc oncogene : implications for future anti-cancer therapies

    Författare :Andreas Höglund; Jonas Nilsson; Thomas Helleday; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Myc; DNA damage; Decitabine; Chk1; Chk2; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Myc is a transcription factor frequently found deregulated in human cancer. Cells with deregulated expression of Myc carry a selective advantage against its neighbours due to the fact that Myc-mediated transcription governs crucial cellular events such as proliferation and growth.

  3. 17. DNA damage affecting thyroidal iodide transport: an explanation to thyroid stunning

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 19. Effects of Antioxidants and Pro-oxidants on Oxidative Stress and DNA Damage using the Comet Assay : Studies on Blood Cells from Type 2 Diabetes Subjects and Mouse Lymphoma Cells

    Författare :Rikard Åsgård; Björn Hellman; Leif Busk; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolic syndrome; fruit and vegetable intake; plasma antioxidants; beta-carotene; alpha-tocopherol; inflammation; oxidative DNA damage; lipid peroxidation; mouse lymphoma assay; ROS; nucleotide pool; viability; DNA dye; Toxicology; Toxikologi;

    Sammanfattning : Diet and oral supplements comprise two distinct sources of antioxidants known to prevent oxidative stress. Beneficial effects from antioxidants have been seen for patients at risk for type 2 diabetes.The aim of this thesis was to evaluate the positive effects of antioxidants against oxidative stress and DNA damage in type 2 diabetes subjects.

  7. 20. UV-induced DNA damage in humans

    Författare :Vladimir J Bykov; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :32P-HPLC; photoproducts; DNA repair; solar simulated radiation; erythema; sunscreens; humans;

    Sammanfattning : Ultraviolet radiation is considered to be the most harmful part of solar energy affecting man. The depletion of the ozone layer around the Earth increases the total exposure to UV-light. The incidence of skin cancer in man has been shown to be associated with exposure to solar radiation, especially to UV-light. LÄS MER
