  1. 1. Quantification of Radiation Induced DNA Damage Response in Normal Skin Exposed in Clinical Settings

    Författare :Martin Simonsson; Ingela Turesson; Gunilla Enblad; Dag Rune Olsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; dermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; gamma-H2AX; 53BP1; p21; checkpoint; apoptosis; mitosis; micro-RNA; miR-34a; Oncology; Onkologi; Oncology; Onkologi;

    Sammanfattning : The structure, function and accessibility of epidermal skin provide aunique opportunity to study the DNA damage response (DDR) of a normaltissue. The in vivo response can be examined in detail, at a molecularlevel, and further associated to the structural changes, observed at atissue level. LÄS MER

  2. 2. Induction and repair of DNA double-strand breaks in human cells exposed to different radiation qualities

    Författare :Irina Radulescu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :DSB; chromatin structure; high-LET; heat-labile sites; PFGE; DNA-PKcs; XRCC1; PARP-1; pATM; gamma-H2AX; 53BP1;

    Sammanfattning : Radiation therapy is used in attempting to kill tumor cells by inducing DNA double- strand breaks (DSB), the most critical DNA lesions. Recent and planned radiation therapy strategies use high-linear energy transfer (LET) radiation to effectively treat malignant tumors. LÄS MER

  3. 3. Cellular effects after exposure to mixed beams of ionizing radiation

    Författare :Elina Staaf; Andrzej Wojcik; Siamak Haghdoost; Eva Forssell-Aronsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; high LET; low LET; mixed beams; combined exposure; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Mixed beams of ionizing radiation in our environment originate from space, the bedrock and our own houses. Radiotherapy patients treated with boron neutron capture therapy or with high energy photons are also exposed to mixed beams of gamma radiation and neutrons. LÄS MER

  4. 4. DNA fragility in the context of neural stem cell fate : a multi-method integrative exploration of genome dynamics

    Författare :Roberto Ballarino; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Recent advances in mapping the complex genetic architecture underlying various debilitating brain disorders have enabled identification of several genetic risk variants. However, these risk variants only explain part of the heritability and vulnerability to these disorders in early development. LÄS MER
