  1. 21. Caspase activation in human neuroblastoma cells: mechanisms and spatiotemporal aspects

    Författare :Elena V. Ivanova; Kerstin Iverfeldt; Boris Zhivotovsky; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; apoptosis; caspase; local caspase activation; neurodegeneration; tau-anchored FRET sensors; tAFS; cancer; neuroblastoma; TNF-related apoptosis inducing ligand; TRAIL; protein kinase C; PKC; X-linked inhibitor of apoptosis protein; XIAP; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Apoptosis is one of the modes of programmed cell death, in which several members of the caspase family of proteases play the central role. However, activation of apoptotic caspases does not necessarily lead to cell death. LÄS MER

  3. 22. Bioinformatics studies on the mechanisms of gene regulation in vertebrates

    Författare :Awaisa Ghazal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Gene regulation implicates an important role in organismal complexity through contributing to phenotypic variation. In my thesis, I studied three diverse components of gene regulatory networks including transcription factors, DNA methylation and microRNAs to elucidate their role in vertebrates. LÄS MER

  4. 23. Cytokines as diagnostic biomarkers in canine pyometra and sepsis

    Författare :Iulia Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Sepsis is a syndrome with high morbidity, mortality and astronomical health care costs and it is challenging to diagnose both in humans and animals due to the lack of suitable diagnostic biomarkers. Although several types of proteins have been suggested as diagnostic biomarkers of sepsis, none of them were shown to be reliable for routine use in the clinical practice. LÄS MER

  5. 24. Regulation of cell polarity and invasion by TGF-β and BMP signaling

    Författare :Mahsa Shahidi Dadras; Aristidis Moustakas; Petra Knaus; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer; cancer stem cells; invasion; metastasis; polarity; TGF-β signaling.;

    Sammanfattning : Transforming growth factor β (TGF-β) and bone morphogenetic protein (BMP) signaling pathways are involved in many physiological processes during embryonic and adult life. TGF-β promotes epithelial to mesenchymal transition (EMT). We identified a gene target of TGF-β signaling, encoding the salt-inducible kinase 1 (SIK1). LÄS MER

  7. 25. Radiation response in human cells : DNA damage formation, repair and signaling

    Författare :Ann-Sofie Gustafsson; Bo Stenerlöw; Andrzej Wojcik; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
