  1. 36. Chromatin Structure: Nucleosome Formation and Positioning

    Författare :Hans R. Widlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; centromere; formation; chromatin; nucleosome; telomere;

    Sammanfattning : In all eukaryotic cells the DNA is complexed with a group of highly basic histone proteins forming nucleosomes and higher order chromatin structures. In the nucleosome the DNA is tightly wrapped, almost two turns, around an octamer of histone proteins. LÄS MER

  3. 37. Studies on the Molecular Biology of the Mouse Pneumotropic Polyomavirus

    Författare :Shouting Zhang; Kristina Dörries; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; murine pneumotropic virus; Kilham mouse polyomavirus; large T antigen; enhancer; regulatory region rearrangement; gene expression regulation; DNA replication; transposable elements; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The Murine Pneumotropic Virus (MPtV), in contrast to the other MurinePolyomavirus (MPyV), appears to be non-tumourigenic in its natural host. Instead, MPtV causes acute pneumonia and can serve as a model in studies of polyomavirus-induced disease. In initial experiments, MPtV large T-antigen (LT) was expressed in a heterologous system.

  4. 38. MOLECULAR AND GENETIC STUDIES OF DLG2 IN NEUROBLASTOMA AND COLORECTAL CANCER

    Författare :Simon Keane; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; Neural crest; Neuroblastoma; colon cancer; DLG2; MYCN; LIN7A; inflammation;

    Sammanfattning : Neuroblastoma is one of the most common extra cranial solid tumors in children. It is one of the most common causes of death amongst the pediatric malignancies. LÄS MER

  5. 39. Peroxiredoxins in Redox Signaling and Aging

    Författare :Friederike Roger; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aging; Peroxiredoxin; Redox Signaling; Caloric restriction; light sensing;

    Sammanfattning : Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not clear through what mechanism peroxiredoxins extend lifespan. LÄS MER

  7. 40. Regulation of mitochondrial gene expression in metazoa

    Författare :Ana Bratic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Drosophila melanogaster; ;

    Sammanfattning : Mitochondria are essential organelles of eukaryotic cells and their main function is to provide the cell with the ubiquitously used energy currency ATP. Impaired energy conversion caused by mitochondrial dysfunction is a direct cause of several human diseases. LÄS MER
