  1. 1. Antigen interaction with B cells in two proliferative disorders : CLL and MGUS

    Author : Eva Hellqvist; Anders Rosén; Jan Ernerudh; Anne Mette Buhl; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The aim of the work presented in this thesis was to elucidate B cell interaction with antigen in the two B cell proliferative disorders chronic lymphocytic leukemia (CLL) and monoclonal gammopathy of undetermined significance (MGUS). In the first part we investigated the antigen specificity of CLL cells and characterized Epstein-Barr virus (EBV)-transformed CLL cell lines with regard to phenotype and genotype. READ MORE

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

    Author : Sujata Bhoi; Richard Rosenquist Brandell; H Denis Alexander; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lymphoid malignancies; CLL; MCL; prognostic markers; micro-RNA; methylation; stereotyped subsets;

    Abstract : 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. READ MORE

  3. 3. Genome-wide epigenetic profiling of B cell leukemia and lymphoma

    Author : Mohammad Hamdy Abdelrazak Morsy; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CLL; PRC2; EZH2; Epigenetics; CpG islands; DNA methylation; ChIP-seq; RNA-seq;

    Abstract : Epigenetic modifications, at the level of DNA methylation and post-translational modifications of histone tails cooperatively function in the organization of the genome, and thereby establish the gene expression profiles, phenotypes, and cellular fates. In this work, we investigated the aberrant epigenome in chronic lymphocytic leukemia (CLL) which is one of the most frequent lymphoid malignancies in the west including the Nordic countries.

  4. 4. Reappraising prognosis in chronic lymphocytic leukemia

    Author : Panagiotis Baliakas; Richard Brandell Rosenquist; Clemens Wendtner; Uppsala universitet; []
    Keywords : CLL; prognosis; Medicinsk genetik; Medical Genetics;

    Abstract : Chronic lymphocytic leukemia (CLL) exhibits remarkable clinical heterogeneity likely reflecting the underlying biological heterogeneity. The genetic landscape of CLL has been recently enriched with mutations within a number of genes proposed as novel prognostic markers. READ MORE

  5. 5. Recurrent Genetic Mutations in Lymphoid Malignancies

    Author : Emma Young; Richard Rosenquist; Larry Mansouri; Lesley Ann Sutton; Dimitar Efremov; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

    Abstract : 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). READ MORE
