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

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

   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

   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

   Sammanfattning : Endocrine tumors arise from endocrine glands. Most endocrine tumors are benign but malignant variants exist. Several endocrine neoplasms display loss of parts of chromosome 11 or 18, produce hormones and responds poorly to conventional chemotherapeutics. The multiple endocrine neoplasia syndromes are mainly confined to endocrine tumors. LÄS MER

5. 4. Predictors of Alcohol Misuse : Role of MAOA Genotype, Methylation, Transcription, and Negative and Positive Environmental factors

   Författare :Megha Bendre; Kent Nilsson; Erika Comasco; Ingrid Nylander; Mia Ericson; Uppsala universitet; []
   Nyckelord :Alcohol; AUD; MAOA; methylation; expression; early-life stress; maltreatment; parent–child relationship; gene–environment interactions.; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Alcohol misuse is a risk factor for alcohol use disorder (AUD). Gene-environment interactions contribute to the risk or resilience for AUD. A functional polymorphism in the promoter of the monoamine oxidase A gene (MAOA-uVNTR), in interaction with negative environment (Eneg), is associated with alcohol misuse and AUD. LÄS MER

7. 5. 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 :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH 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
