1 Department of Genetics, Microbiology and Toxicology (GMT) Radiation Biology Prof. Andrzej Wojcik Prof. Mats Harms-Ringdahl Toxicology Prof. Thomas Helleday Prof. Ulf Rannug Prof. Dag Jenssen Centre for Radiation Protection Research (CRPR) (CRPR) Molecular Mechanisms in Cancer / Dag Jenssen, GMT

2 Radiation Biology (AW & MHR) 2 Profs 1 Postdoc 5 PhD students 2 Master students Mechanisms of cellular and systemic effects of exposure to ionising radiation EU grants Swedish Radiation Safety Authority

3 Radiation Biology (AW & MHR) Mechanisms of individual sensitivity to ionising radiation: Differences in DNA-damage response pathways between cohorts of patients with normal or severe healthy tissue reactions to tumour therapy. Differences in DNA-damage response pathways between cohorts of patients with normal or severe healthy tissue reactions to tumour therapy. Screening for polymorphisms in genes for DNA- repair, cell cycle regulation and apotosis Screening for polymorphisms in genes for DNA- repair, cell cycle regulation and apotosis Search for diagnostic tools to identify the persons at risk. Search for diagnostic tools to identify the persons at risk. Patient with severe side-effect following radiotherapy

4 Radiation Biology (AW & MHR) What are the risks of radiation at low doses? Can we improve biological dosimetry? New technologies will determine doses with high precision? New biomarkers for DNA- damage response pathways Is the dose response curve non-linear? Identification of new response pathways for very low doses. ?
