  1. 1. Melanophore signaling : regulation and application

    Författare :Tony P. M. Andersson; Ethan Lerner; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Melanophores are pigment-containing cells responsible for quick physiological color changes in lower vertebrates due to redistribution of melanosomes, pigment granules. We have studied melanophores from African clawed frog, Xenopus laevis. LÄS MER

  3. 2. Ras-MAPK signaling in differentiating SH-SY5Y human neuroblastoma cells

    Författare :Anna-Karin Olsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Neuroblastoma; SH-SY5Y; differentiation; neurite; Ras; MAPK; PKC; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Neuroblastoma is a malignant childhood cancer, originating from sympathetic neuroblasts of the peripheral nervous system. Neuroblastoma is a heterogenous group of tumours, while some are highly malignant others can spontaneosly mature into a more benign form or regress. LÄS MER

  4. 3. Altered cell signaling linked to neurodegeneration : Studies on scrapie-infected neuroblastoma cells and activated microglia

    Författare :Christina Svensson; Tiit Land; Gianluigi Forloni; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prion disease; Inflammation; MAPK; Microglia activation; Neuroblastoma; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

    Sammanfattning : Prion diseases are neurodegenerative disorders that can affect humans and animals. The underlying event is a conformational change of the normal cellular prion protein (PrPC) into an aberrant isoform termed PrP-scrapie (PrPSc). PrPSc is thought to lead to neurodegeneration and activation of glial cells. LÄS MER

  5. 4. DNA checkpoint override and redox signaling in Schizosaccharomyces pombe

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

    Sammanfattning : 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. LÄS MER

  7. 5. Signaling determinants in Trojan horse-mediated dissemination of Toxoplasma gondii

    Sammanfattning : Toxoplasma gondii is an obligate intracellular parasite that infects all warm-blooded vertebrates including one third of the global human population. While infection is typically asymptomatic in healthy human hosts, reactivated and acute infection in immunosuppressed or immunecompromised individuals can lead to lethal toxoplasmic encephalitis After ingestion, the parasite crosses the intestinal epithelium and rapidly achieves systemic dissemination, ultimately establishing chronic infection in the brain.
