  2. 11. Histone H1 : Subtypes and phosphorylation in cell life and death

    Author : Anna Gréen; Ingemar Rundquist; Peter Söderkvist; Rolf Ohlsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi;

    Abstract : The genetic information of a human diploid cell is contained within approximately 2 metres of linear DNA. The DNA molecules are compacted and organized in various ways to fit inside the cell nucleus. Various kinds of histones are involved in this compaction. One of these histones, histone H1 is the topic of the present thesis. READ MORE

  4. 12. Role of MAP Kinases in the Life and Death of Beta-cells

    Author : Natalia Makeeva; Nils Welsh; Godfried Roomans; Thomas Mandrup-Poulsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; diabetes; beta-cell; p38 MAPK; nitric oxide; apoptosis; Cellbiologi; Cell biology; Cellbiologi;

    Abstract : The development of diabetes mellitus depends on the balance between beta-cell proliferation and death. As mitogen-activated protein kinases (MAPK) may control this balance, the aim of this study was to investigate the events leading to MAPK activation in beta-cells and the consequences of these events.

  5. 13. Imaging-based methods for NK cell studies at the single-cell level

    Author : Quentin Verron; Björn Önfelt; Niklas Sandström; Michael Dustin; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; NK cells; microscopy; single-cell; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Abstract : The immune system provides defense against infectious agents such as viruses, bacteria and parasites. Besides eliminating extracellular agents, the immune system also constantly monitors our own cells for signs of transformation, including tumor development and virus infection. READ MORE

  6. 14. Radiation response in human cells : DNA damage formation, repair and signaling

    Author : Ann-Sofie Gustafsson; Bo Stenerlöw; Andrzej Wojcik; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionizing radiation; heat-labile sites; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. READ MORE

  7. 15. The receptor tyrosine kinase Met and the protein tyrosine phosphatase PTPN2 in breast cancer

    Author : Cynthia Veenstra; Olle Stål; Gizeh Perez-Tenorio; Pietras Kristian; Linköpings universitet; []
