  2. 1. Gene Expression Studies of Hematologic Malignacies

    Author : Anna Andersson; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; cancer; onkologi; Cytologi; oncology; Cytology; acute myeloid leukemia; acute lymphoblastic leukemia; normal hematopoietic cells; cDNA microarray; gene expression profiling; hematopoiesis; pediatric leukemia; fusion gene; Pediatrics; Pediatri; Clinical genetics; Klinisk genetik; cancerology; Hematologi; extracellulära vätskor;

    Abstract : The general aim of this thesis was to characterize hematologic malignancies using gene expression profiling in order to obtain an improved classification and to study deregulated transcriptional networks in leukemia. In the first study (Article I), the gene expression profiles of hematologic cell lines were analyzed to investigate whether such cell lines maintain expression profiles that are characteristic of their primary genetic changes.

  4. 2. Classification and Computational Methods in Gene Expression Data Analysis

    Author : Cecilia Ritz; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; medicinsk informatik; Bioinformatics; medical informatics; biomathematics biometrics; missing values; leukemia; cDNA microarray data; supervised classification; breast cancer; prognostic markers; biomatematik;

    Abstract : The technology of cDNA microarrays has given us the possibility to monitor the state of cells by measuring the activity of thousands of genes simultaneously. This high-throughput techniqe has in cancer research allowed exploratory studies of molecular mechanisms behind for example metastasis and response to therapy. READ MORE

  5. 3. Probalistic Methods In Genomic Data Analysis

    Author : Thomas Breslin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pathway profiling; Bioinformatics; medical informatics; biomathematics biometrics; Bioinformatik; medicinsk informatik; differential gene expression; probabilistic methods; Natural science; Naturvetenskap; biomatematik; annotation analysis; microarray; Fysicumarkivet A:2004:Breslin;

    Abstract : In this thesis, three aspects of gene expression data analysis are discussed: Differential gene expression is addressed by a probabilistic method. Gene annotation enrichment analysis is discussed in the context of multiple hypothesis testing and the choice of null hypothesis. READ MORE

  6. 4. Clinical and Experimental Studies in Chronic Myeloid Leukemia : Studies of Treatment Outcome, In Vitro Cellular Drug Resistance and Gene Expression

    Author : Ulla Olsson-Strömberg; Bengt Simonsson; Elin Lindhagen; Gisela Barbany; Johan Richter; Uppsala universitet; []
    Keywords : Medicine; chronic myeloid leukemia; adult; stem cell transplantation; mobilization of Ph-negative stem cells; in vitro assay; imatinib; gene expression; Medicin;

    Abstract : The aims of the studies described in the thesis were to investigate different treatment strategies in chronic myeloid leukemia (CML) patients. Furthermore, activity of imatinib was investigated by in vitro cytotoxicity assay, and the gene expression pattern in interferon treated patients. READ MORE

  7. 5. Array based genetic profiling of chronic lymphocytic leukemia

    Author : Rebeqa Gunnarsson; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prognostic markers; copy-number neutral loss of heterozygosity; copy-number aberrations; chronic lymphocytic leukemia; genomic microarrays; clonal evolution; stereotyped B-cell receptors;

    Abstract : Although no common genetic defect has been described in chronic lymphocytic leukemia (CLL), recurrent genomic aberrations (i.e. deletions of chromosome 11q, 13q, 17p and trisomy 12) are important for prognostication. Deletion of 13q as single aberration is associated with the best prognosis, whereas del(11q) and del(17p) predict a poor outcome. READ MORE
