  1. 1. The balance of splicing : A novel insight into the splicing regulation of high-risk HPV E6 and E7 oncogenes

    Författare :Johanna Jönsson; Naoko Kajitani; Stefan Schwartz; Ola Forslund; Francesca Aguilo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HPV; splice donor; splice acceptor; cis-element; trans-acting factor; pre-mRNA splicing; splicing regulation.; Medical Virology; Medicinsk virologi;

    Sammanfattning : HPV is associated with several cancers. The genome consists of a long control region, early (E1, E2, E4, E5, E6 and E7) and late (L1 and L2) genes. The E6 and E7 proteins prevent cells from entering apoptosis and regulate the cell cycle. A deregulated expression of these can result in malignant transformations. LÄS MER

  3. 2. Eukaryotic Ribosome Biogenesis : Focus on the function of the assembly factor Mrd1p

    Författare :Åsa Segerstolpe; Lars Wieslander; Susan Gerbi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome biogenesis; nucleolus; pre-rRNA processing; RNA-binding proteins; Mrd1; Molecular Biology; molekylärbiologi;

    Sammanfattning : The ribosome, the protein factory of the cell, is essential for all life forms. The ribosome is a large RNA-protein machine. It is built in a complex, multi-step process that involves a large number of accessory trans-acting factors and the synthesis consumes a considerable part of the cellular energy. LÄS MER

  4. 3. The Epigenetics of Gene Transcription and Higher Order Chromatin Conformation

    Författare :Vijay Kumar Tiwari; Rolf Ohlsson; Terumi Kohwi-Shigematsu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; DNA-protein interactions; Nuclear organization; Transcriptional regulation; Higher order chromatin conformations; Epigenetic reprogramming; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : It is becoming increasingly clear that long-range control of gene expression is mediated through direct physical interactions between genes and regulatory elements, either intra- or interchromosomally. In addition to transcriptional initiation, formation of active chromatin hubs seem to be crucial for increased transcriptional efficiency as well as insulation from neighbouring heterochromatic environment.

  5. 4. Molecular characterization of the Tick-borne encephalitis virus : Environments and replication

    Författare :Wessam Melik; Magnus Johansson; Sonja Best; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tick-borne encephalitis virus; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The flavivirus genus is of major concern for world morbidity and mortality and includes viruses causing both encephalitic as well as hemorrhagic diseases. The incidence of Tick-borne encephalitis is increasing in many European countries and several reports have emphasized the expansion of the main vector, Ixodes ricinus. LÄS MER

  7. 5. Initiation of Mammalian Mitochondrial DNA Replication

    Författare :Elisabeth Jemt; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mitochondria; mtDNA; DNA replication;

    Sammanfattning : Mitochondria produce most of the adenosine triphosphate required in a eukaryotic cell and they contain their own genome. The mitochondrial DNA (mtDNA) is a double stranded circular molecule that codes for proteins required for cellular respiration and RNA molecules involved in translation of these proteins. LÄS MER
