  1. 1. Clinical and molecular studies of liposarcoma

    Author : Katarina Engström; Göteborgs universitet; []
    Keywords : Liposarcoma; radiotherapy; prognostic factors; transfection; FUD-DDIT3; adipogenesis; microarray expression analysis; cell cycle; immunohistochemistry;

    Abstract : Aims: (1) To analyse clinicopathological characteristics, treatment and outcome of liposarcoma, and to determine whether, and how, the Scandinavian Sarcoma Group (SSG) treatment guidelines were followed; (2) to analyse tumour volume and morphology response after radiotherapy in myxoid/round cell liposarcoma (MLS/RCLS); (3) to examine the role of the MLS-specific fusion gene FUS-DDIT3 in development of liposarcomas; and (4) to analyse expression patterns of cell cycle regulating proteins in MLS. Methods: (1) A total of 319 liposarcomas reported between 1986?1998 to the SSG Register were reviewed. READ MORE

  2. 2. Molecular studies of genetic changes in myxoid and round cell liposarcoma

    Author : Sofia Järnum; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancerology; Cytologi; onkologi; cancer; Medicine human and vertebrates ; Medicin människa och djur ; oncology; Cytology; autocrine loop; RDA; persephin; RET; LEPREL1; translocation; fusion gene; liposarcoma; TLS; CHOP;

    Abstract : Chromosomal translocations commonly result in the production of fusion genes and the fusion genes are often tumor-type specific. In myxoid and round cell liposarcomas (MLS/RCLS), almost 95% of the cases carry a t(12;16)(q13;p11). In the remaining 5% of the MLS/RCLS tumors, another translocation and fusion gene can be found, i.e. READ MORE

  3. 3. Liposarcomas - proliferation, senescence and the role of DDIT3

    Author : Christina Kåbjörn-Gustafsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liposarcoma; FUS-DDIT3; TP53; senescence;

    Abstract : Lipomatous tumors comprise benign and malignant forms called lipomas and liposarcomas. Myxoid/round cell liposarcoma (MLS/RCLS) is the second most common liposarcoma and is characterized by the fusion oncogenes FUS-DDIT3 or EWSR1-DDIT3. READ MORE

  4. 4. Studies of Fusion Oncogenes and Genomic Imbalances in Human Tumors

    Author : Fredrik Persson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer genetics; fusion oncogene; gene amplification; array CGH; PLAG1; HMGA2; FGFR1; MDM2; pleomorphic adenoma; carcinoma ex pleomorphic adenoma; liposarcoma;

    Abstract : Cancer is a genetic disease caused by mutations and chromosome rearrangements affecting oncogenes and tumor suppressor genes in particular. Molecular analyses of recurrent translocations in hematological disorders, as well as in certain solid tumor types, have shown that they frequently result in fusion oncogenes. READ MORE

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

    Author : David Gisselsson Nord; Avdelningen för klinisk genetik; []
    Keywords : 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;

    Abstract : 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. READ MORE
