  2. 1. DNA checkpoint override and redox signaling in Schizosaccharomyces pombe

    Author : Johanna J Sjölander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caffeine; Cell cycle; Checkpoint; Cdc25; Wee1; TORC1; FHIT; Proliferation; Aph1; Redox; Hypoxia; H2O2; Cysteine; Thiol; Allosteric; MAPK; Sty1; MAPKK; Wis1;

    Abstract : This thesis covers intracellular stress signaling through genotoxic stress, overriding of checkpoint control, as well as cellular redox status in hypoxic and oxidative stress Papers I and II: Caffeine has been shown to override cell cycle checkpoints in humans as well as in the fission yeast Schizosaccharomyces pombe. Understanding of the mechanism may aid in the development of compounds with similar overriding mechanisms for sensitization in cancer therapy. READ MORE

  4. 2. DNA precursor asymmetries, Mismatch Repair and their effect on mutation specificity

    Author : Robert Buckland; Andrei Chabes; Juan Méndez; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA Replication Fidelity; Mutations; dNTP pools; Mismatch Repair; Checkpoint; Ribonucleotide Reductase; Msh2; medicinsk biokemi; Medical Biochemistry; molekylärbiologi; Molecular Biology;

    Abstract : In order to build any structure, a good supply of materials, accurate workers and quality control are needed. This is even the case when constructing DNA, the so-called “Code of Life.” For a species to continue to exist, this DNA code must be copied with incredibly high accuracy when each and every cell replicates.

  5. 3. DNA Damage Response of Normal Epidermis in the Clinical Setting of Fractionated Radiotherapy : Evidence of a preserved low-dose hypersensitivity response

    Author : Fredrik Qvarnström; Ingela Turesson; Gunilla Enblad; Mats Harms-Ringdahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; γH2AX; 53BP1; checkpoint; p21; apoptosis; mitosis; Oncology; Onkologi; Oncology; onkologi;

    Abstract : Investigations of DNA damage response (DDR) mechanisms in normal tissues have implications for both cancer prevention and treatments. The accumulating knowledge about protein function and molecular markers makes it possible to directly trace and interpret cellular DDR in a tissue context. READ MORE

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

    Author : Martin Simonsson; Ingela Turesson; Gunilla Enblad; Dag Rune Olsen; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Immunological Checkpoint Blockade and TLR Stimulation for Improved Cancer Therapy

    Author : Sara Mangsbo; Thomas Tötterman; Angelica Loskog; Rolf Kiessling; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CpG ODNs; TLR-9; CTLA-4; PD-1; PD-L1; B7. H1; immunotherapy; checkpoint blockade; bladder cancer; cancer; complement; TLRs; Compstatin; properdin; C3; experimental animal model; whole blood loop system; combination therapies; Clinical immunology; Klinisk immunologi; Tumour immunology; Tumörimmunologi; immunologi; Immunology;

    Abstract : This thesis concerns the investigation of novel immunotherapies for cancer eradication. CpG therapy was used in order to target antigen-presenting cells (APCs), facilitating antigen presentation and activation of T cells. READ MORE
