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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis Uppsala

    Författare :Millaray Marincevic; Uppsala universitet.; [2010]
    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; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin 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

  2. 2. Genomic and transcriptomic sequencing in chronic lymphocytic leukemia

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Diego Cortese; Uppsala universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic; lymphocytic; leukemia; CLL; genomics; transcriptomics; DNA; RNA; mutations; NGS; whole-exome; sequencing; prognostic; markers; TP53; SF3B1; RPS15; relapse; stereotyped; subsets.;

    Sammanfattning : Identification of recurrent mutations through next-generation sequencing (NGS) has given us a deeper understanding of the molecular mechanisms involved in chronic lymphocytic leukemia (CLL) development and progression and provided novel means for risk assessment in this clinically heterogeneous disease. In paper I, we screened a population-based cohort of CLL patients (n=364) for TP53, NOTCH1, SF3B1, BIRC3 and MYD88 mutations using Sanger sequencing, and confirmed the negative prognostic impact of TP53, SF3B1 or NOTCH1 aberrations, though at lower frequencies compared to previous studies.

  3. 3. Recurrent Genetic Mutations in Lymphoid Malignancies

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Emma Young; Uppsala universitet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lymphoid malignancies; mutations; CLL; stereotypy; subsets; PMBL; NFKBIE; EGR2; whole-genome sequencing; Molekylär genetik; Molecular Genetics; Oncology; Onkologi;

    Sammanfattning : In recent years, the genetic landscape of B-cell derived lymphoid malignancies, including chronic lymphocytic leukemia (CLL), has been rapidly unraveled, identifying recurrent genetic mutations with potential clinical impact. Interestingly, ~30% of all CLL patients can be assigned to more homogeneous subsets based on the expression of a similar or “stereotyped” B-cell receptor (BcR). LÄS MER

  4. 4. Prognostic markers and DNA methylation profiling in lymphoid malignancies

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sujata Bhoi; Uppsala universitet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lymphoid malignancies; CLL; MCL; prognostic markers; micro-RNA; methylation; stereotyped subsets;

    Sammanfattning : In recent years, great progress has been achieved towards identifying novel biomarkers in lymphoid malignancies, including chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL), at the genomic, transcriptomic and epigenomic level for accurate risk-stratification and prediction of treatment response. In paper I, we validated the prognostic relevance of a recently proposed RNA-based marker in CLL, UGT2B17, and analyzed its expression levels in 253 early-stage patients. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Fiona Murray; Uppsala universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic lymphocytic leukaemia; immunoglobulin genes; somatic hypermutation; stereotyped B cell receptors; antigen selection; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics Molecular biology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik 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.
