  1. 1. Molecular and Genetic Evidence for Antigen Selection in the Pathogenesis of Chronic Lymphocytic Leukemia

    Författare :Lesley Ann Sutton; Richard Rosenquist; John Gribben; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IGHV4-34; microenvironment; stereotypy; immunoglobulin; intraclonal diversification; clonal evolution;

    Sammanfattning : Antigens play a critical role in the development of chronic lymphocytic leukemia (CLL) by binding to and stimulating leukemic precursor cells at some point during CLL ontogeny. Nevertheless, much remains unknown and further studies are necessary before an accurate model of antigen-drive can be ascertained. LÄS MER

  3. 2. Molecular Genetic and DNA Methylation Profiling of Chronic Lymphocytic Leukaemia : A Focus on Divergent Prognostic Subgroups and Subsets

    Författare :Nicola Cahill; Richard Rosenquist; Larry Mansouri; Fergus Ryan; Denis Alexander; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA methylation; Chronic lymphocytic leukemia; SNP; array; IGHV3-21; IGHV4-34; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Genetics; Genetik; Medical Genetics; Medicinsk genetik; Molecular Biology; Molekylärbiologi; Molekylär genetik; Molecular Genetics; Oncology; Onkologi;

    Sammanfattning : Advancements in prognostication have improved the subdivision of chronic lymphocytic leukaemia (CLL) into diverse prognostic subgroups. In CLL, IGHV unmutated and IGHV3-21 genes are associated with a poor-prognosis, conversely, IGHV mutated genes with a favourable outcome. LÄS MER

  4. 3. Array based genetic profiling of chronic lymphocytic leukemia

    Författare :Rebeqa Gunnarsson; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prognostic markers; copy-number neutral loss of heterozygosity; copy-number aberrations; chronic lymphocytic leukemia; genomic microarrays; clonal evolution; stereotyped B-cell receptors;

    Sammanfattning : Although no common genetic defect has been described in chronic lymphocytic leukemia (CLL), recurrent genomic aberrations (i.e. deletions of chromosome 11q, 13q, 17p and trisomy 12) are important for prognostication. Deletion of 13q as single aberration is associated with the best prognosis, whereas del(11q) and del(17p) predict a poor outcome. LÄS MER

  5. 4. Array-based Characterization of Chronic Lymphocytic Leukemia : - with Focus on Subsets Carrying Stereotyped B-cell Receptors

    Författare :Millaray Marincevic; Richard Rosenquist; Andreas Rosenwald; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukemia; array-based characterization; stereotyped B-cell receptors; subsets; antigens; SNP array; gene expression array; methylation array; Clinical genetics; Klinisk genetik; Clinical Genetics; Klinisk genetik;

    Sammanfattning : In chronic lymphocytic leukemia (CLL), the presence of multiple subsets expressing ‘stereotyped’ B-cell receptors (BCRs) has implicated antigen(s) in leukemogenesis. These stereotyped subsets display similar immunoglobulin (IG) gene usage, almost identical complementarity determining region 3’s and may share clinical features. LÄS MER

  7. 5. Stereotyped B Cell Receptors in Chronic Lymphocytic Leukaemia : Implications for Antigen Selection in Leukemogenesis

    Författare :Fiona Murray; Richard Rosenquist Brandell; Kostas Stamatopoulos; Gunilla Enblad; Gerard Tobin; Manlio Ferrarini; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukaemia; immunoglobulin genes; somatic hypermutation; stereotyped B cell receptors; antigen selection; Molecular biology; Molekylärbiologi;

    Sammanfattning : Biased immunoglobulin heavy variable (IGHV) gene usage and distinctive B-cell receptor (BCR) features have been reported in chronic lymphocytic leukaemia (CLL), which may reflect clonal selection by antigens during disease development. Furthermore, the IGHV gene mutation status distinguishes two clinical entities of CLL, where patients with unmutated IGHV genes have an inferior prognosis compared to those with mutated IGHV genes.
