1. DNA methylation signatures in precursor lymphoid neoplasms : with focus on clinical implications & the biology behind
Sammanfattning : 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. LÄS MER
2. Gene Expression and DNA Methylation in Acute Lymphoblastic Leukemia
Sammanfattning : 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. LÄS MER
3. DNA methylation profiling of CNS tumors; implications for clinical diagnostics
Sammanfattning : Diffuse gliomas and meningiomas are the most common primary tumors of the central nervous system (CNS) in adults and these tumors cause significant morbidity and mortality worldwide. Deregulation of the epigenetic mechanisms, e.g. LÄS MER
4. Molecular Genetic and DNA Methylation Profiling of Chronic Lymphocytic Leukaemia : A Focus on Divergent Prognostic Subgroups and Subsets
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
5. DNA methylation as a prognostic marker i acute lymphoblastic leukemia
Sammanfattning : 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. LÄS MER
