  1. 1. Somatic Genetic Variation in Children: from Mosaicism to Cancer

    Författare :Anders Valind; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Somatic Mosaicism; Cancer; Tumor heterogeneity; Neuroblastoma; Wilms Tumor; Rhabdomyosarcoma; Aneuploidy;

    Sammanfattning : This thesis concerns various aspects of somatic mosaicism and genetic intratumor heterogeneity in childhood cancer.In paper I, I show that aneuploidy in itself does not lead to the level of chromosomal instability that is typically seen in malignant cells. This finding strongly argues against the so called autocatalytic theory of carcinogenesis. LÄS MER

  3. 2. The Wilms' tumor gene 1 (WT1) and leukemia -new insights and further complexity

    Författare :Emelie Svensson; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Haematology; extracellular fluids; Hematologi; extracellulära vätskor; Cytologi; cancerology; oncology; Cytology; Medicin människa och djur ; Medicine human and vertebrates ; Cofilin 1; NDRG2; IRF-8; BCR ABL1; hematopoiesis; Wilms´ tumor gene 1; leukemia;

    Sammanfattning : The Wilms tumor gene 1 (WT1) encodes a zinc-finger containing transcription factor which is highly expressed in immature hematopoietic progenitor cells. A high expression of WT1 and the presence of somatic mutations in acute leukemia indicate a role for WT1 in the pathogenesis of leukemia. LÄS MER

  4. 3. Significance of Wilms’ tumor gene 1 as a biomarker in acute leukemia and solid tumors

    Författare :Charlotta Andersson; Eva Lundin; Aihong Li; Andreas Jonsson; Xingru Li; David M. Loeb; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wilms’ tumor gene 1; biomarker; leukemia; renal cell carcinoma; ovarian carcinoma; Clinical Chemistry; klinisk kemi; patologi; Pathology;

    Sammanfattning : Wilms’ tumor gene 1 (WT1) is a zinc finger transcriptional regulator with crucial functions in embryonic development. Originally WT1 was described as a tumor suppressor gene, but later studies have shown oncogenic properties of WT1 in a variety of tumors. Because of its dual functions in tumorigenesis, WT1 has been described as a chameleon gene. LÄS MER

  5. 4. Wilms' tumor gene 1 in different types of cancer

    Författare :Xingru Li; Aihong Li; Karin Nylander; Eva Lundin; Xiaolian Gu; David M. Loeb; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; WT1; AML; MRD; ccRCC; SNPs; DNA methylation; SCCHN; p63; Clinical Chemistry; klinisk kemi;

    Sammanfattning : The Wilms’ tumor gene 1 (WT1) was first reported as a tumor suppressor gene in Wilms’ tumor. However, later studies have shown the oncogenic properties of WT1 in a variety of tumors. It was recently proposed that WT1 was a chameleon gene, due to its dual functions in tumorigenesis. LÄS MER

  7. 5. Development and Application of Human Chromosome 22 Genomic Microarray : Chromosome 22-Associated Disorders Analyzed by Array-Based Comparative Genomic Hybridization

    Författare :Magdalena Benetkiewicz; Jan Dumanski; Niklas Dahl; Frank Speleman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; DNA copy number changes; chromosome 22; genomic microarray; array-CGH; schwannoma; neurofibromatosis type 2; ovarian carcinoma; breast cancer; Wilms tumor; Genetik; Genetics; Genetik;

    Sammanfattning : The array-based form of comparative genomic hybridization (array-CGH) is a new methodology that has shown to be of significant importance. This thesis focuses on the development of array-CGH with the aim to define candidate regions/genes on chromosome 22 in a wide spectrum of cancer-related conditions. LÄS MER
