  1. 1. DNA methylation signatures in precursor lymphoid neoplasms with focus on clinical implications &  the biology behind

    University dissertation from Umeå : Umeå University

    Author : Zahra Haider; Umeå universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Acute Lymphoblastic Leukemia; Lymphoma; T-ALL; BCP-ALL; T-LBL; DNA methylation; CIMP; Prognosis; TAL1; HOX.;

    Abstract : Precursor lymphoid neoplasms, namely acute lymphoblastic leukemias (ALL) and lymphoblastic lymphomas (LBL), are characterized by an aggressive proliferation of malignant progenitor B- or T-cells. To improve risk classification at diagnosis, better prognostic and treatment stratifying biomarkers are needed. READ MORE

  2. 2. Gene Expression and DNA Methylation in Acute Lymphoblastic Leukemia

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jessica Nordlund; Uppsala universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Digital gene expression; Allele-specific gene expression; DNA methylation; Epigenetics; Acute lymphoblastic leukemia; Molekylär medicin; Molecular Medicine;

    Abstract : Pediatric acute lymphoblastic leukemia (ALL) is the most common malignancy in children, which results from the malignant transformation of progenitor cells in the bone marrow into leukemic cells. The precise mechanisms for this transformation are not well defined, however recent studies suggest that aberrant regulation of gene expression or DNA methylation may play an important role.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sujata Bhoi; Uppsala universitet.; [2017]
    Keywords : 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

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nicola Cahill; Uppsala universitet.; [2012]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. DNA methylation as a prognostic marker i acute lymphoblastic leukemia

    University dissertation from Umeå : Umeå universitet

    Author : Magnus Borssén; Umeå universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA methylation; acute lymphoblastic leukemia; T-ALL; Relapse; Telomere length; patologi; Pathology; Pediatrics; pediatrik;

    Abstract : Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Most ALL cases originate from immature B-cells (BCP-ALL) and are characterized by reoccurring structural genetic aberrations. These aberrations hold information of the pathogenesis of ALL and are used for risk stratification in treatment. READ MORE
