  1. 31. Studies of Budding Yeast Transcription Factors Acting Downstream of Nutrient Signaling Pathways

    Författare :Niklas Nordberg; Hans Ronne; Anders Blomberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budding yeast; nutrient signaling; glucose repression; aging; caloric restriction; JmjC; histone demethylation; Mig1; Mig2; Mig3; Gis1; Rph1; Molekylär genetik; Molecular Genetics;

    Sammanfattning : Being able to respond to extracellular cues such as nutrients and growth factors is of vital importance to all living cells. Pathways have therefore evolved which can sense the extracellular status, transmit a signal through the cell and affect gene expression, which ultimately enables adaptation. LÄS MER

  3. 32. Effects of Dopamine Signaling on Recovery and Inflammation after Ischemic Stroke

    Författare :Enida Kuric; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Ischemic stroke, resulting from occlusion of a brain artery is the most common type of stroke with a prevalence of 15 million people and the leading cause of long-term disability worldwide. Importantly, partial spontaneous recovery of lost neurological functions occurs mainly during the first months after stroke onset, albeit to a limited extent. LÄS MER

  4. 33. Effects of Alzheimer's and Parkinson's disease gene mutation on cell signaling

    Författare :Nodi Dehvari; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) and Parkinson's disease (PD) are the major neurodegenerative disorders affecting the elderly. The discovery of genes causing familial forms of these disorders has contributed enormously towards our understanding of underlying pathogenic mechanisms. LÄS MER

  5. 34. Effects of chemotherapy on bone growth and chondrocyte cell death signaling

    Författare :Farasat Zaman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Glucocorticoids (GCs) are widely used in both children and adults to treat common inflammatory diseases, including asthma, rheumatoid arthritis, ulcerative colitis and Crohn’s disease. However, a multitude of undesired side effects have been reported in patients being treated with GCs, such as osteoporosis, obesity, metabolic disturbances, myopathy and decreased linear bone growth (in children).

  7. 35. Molecular studies of pancreatic cancer: Characterization of the transforming growth factor beta signaling pathway

    Författare :Tord Jonson; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SMAD4; PCR; FISH; cytogenetics; chromosome; pancreatic cancer; TGFB signaling; cytogenetik; Genetik; Genetics;

    Sammanfattning : In the present thesis, genetic abnormalities in pancreatic cancer were studied, with special emphasis on alterations of components involved in the transforming growth factor beta (TGFB) signaling pathway. In the first study, fluorescence in situ hybridization and cytogenetic analyses revealed aberrations of chromosome 18 in all 13 pancreatic carcinoma cell lines studied, in particular frequent breaks close to the centromere of chromosome arm 18q.
