1. 1. Epigenetic dysregulation in relation to psychiatric traits in adolescence and adulthood

   Författare :Adrian Desai Boström; Helgi B. Schiöth; Daniel Nätt; Uppsala universitet; []

   Sammanfattning : Epigenetics has evolved into a key research focus in the field of psychiatry. DNA methylation is the most researched epigenetic mechanism. In paper I-III, 130 and 93 adolescents were randomly recruited at two separate intervals. LÄS MER

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

   Författare :Zahra Haider; Sofie Degerman; Magnus Hultdin; Göran Roos; Pieter van Vlierberghe; Umeå universitet; []
   Nyckelord :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.;

   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

4. 3. Gene Expression and DNA Methylation in Acute Lymphoblastic Leukemia

   Författare :Jessica Nordlund; Syvänen Ann-Christine; Xavier Estivill; Uppsala universitet; []
   Nyckelord :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;

   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

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

   Författare :Sujata Bhoi; Richard Rosenquist Brandell; H Denis Alexander; Uppsala universitet; []
   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

7. 5. 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
