  1. 1. Chromosomal Instability and Genomic Amplification in Bone and Soft Tissue Tumours

    Författare :David Gisselsson Nord; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear atypia; kinetochore; anaphase bridge; p53; breakage-fusion-bridge cycle; TP53; HMGIC; MDM2; mitotic instability; genomic instability; FISH; osteosarcoma; liposarcoma; amplification; tumour; chromosome; cytogenetics; Clinical genetics; Klinisk genetik;

    Sammanfattning : Acquired genetic abnormalities are found in all types of malignant tumours and may contribute to neoplastic processes by altering protein structure or dosage. Many bone and soft tissue tumours (BSTT) are characterised by complex patterns of chromosome changes, including extensive intratumour heterogeneity and amplification of DNA sequences. LÄS MER

  3. 2. Microtubule and spindle pole body regulation in the budding yeast mitotic spindle

    Författare :Marjan Abbasi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The microtubule organizing center (MTOC) is a specialized structure with a main function in microtubule (MT) nucleation and organization. In higher eukaryotes, the main MTOC is known as the centrosome, and its functional equivalent in yeast is the spindle pole body (SPB). LÄS MER

  4. 3. Microtubule and chromosome dynamics during mitosis in budding yeast

    Författare :Alexander Julner Dunn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : As a cell divides, DNA must be replicated and faithfully segregated between the mother and daughter cells. This segregation is facilitated by the mitotic spindle, assembled to pull sister chromatids apart as the cell divides. LÄS MER

  5. 4. Characterization of the inner nuclear membrane protein Samp1, during interphase and mitosis

    Författare :Veronica J. Larsson; Einar Hallberg; Katharine S. Ullman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Samp1; LINC complex; nuclear lamina; MCLIP; nuclear envelope; spindle assembly; spindle stability; k-fiber; gamma tubulin; Aurora B; Haus6; Augmin; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : The nucleus, a hallmark in eukaryotic cells, contains the genome separating it from molecules in the cytoplasm. The nucleus is surrounded by a nuclear envelope consisting of two concentric membranes, the outer nuclear membrane and the inner nuclear membrane, the nuclear lamina and nuclear pore complexes.

  7. 5. The roles of inner nuclear membrane proteins during interphase and mitosis

    Författare :Veronica J. Larsson; Einar Hallberg; Neus Visa; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Samp1; mitotic spindle; centrosome; LINC complex; Lamina; Sun1; mitosis; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : The nuclear envelope (NE) consists of two concentric membranes, the outer nuclear membrane (ONM) and the inner nuclear membrane (INM). The LINC (linker of nucleoskeleton and cytoskeleton) complex spans both the ONM and the INM connecting the cytoskeleton to the nucleoskeleton and chromatin. LÄS MER
