  1. 1. Genomic Profiling, Mutations and Deranged Signaling in Esophageal Cancer and Hereditary Colorectal Cancer

    Författare :Anna Isinger Ekstrand; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal cancer; hereditary cancer; HNPCC; copy number analysis; CGH; gene expression; Wnt; PIK3CA; CHEK2; gastric cancer; colorectal cancer;

    Sammanfattning : Esophageal cancer and colorectal cancer represents two major types of gastrointestinal tumors. Though refined surgery and introduction of novel chemotherapeutics have improved outcome, more than 2500 Swedes die from these diseases every year. Novel markers for early diagnosis, prognosis and treatment prediction are therefore needed. LÄS MER

  3. 2. Molecular Genetic Characterization of Acute Lymphoblastic Leukemia with a Poor Prognosis

    Författare :Setareh Safavi; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute lymphoblastic leukemia; hypodiploidy; adult acute lymphoblastic leukemia;

    Sammanfattning : Acute lymphoblastic leukemia (ALL) affects individuals at all ages, with peak incidences in children 50 years. ALL is broadly categorized into B-cell precursor (BCP) and T-cell ALL with specific clinical features associated with outcome. LÄS MER

  4. 3. IKAROS and LEUKEMIA

    Författare :Linda Olsson; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatric acute lymphoblastic leukemia; relapse; risk-stratifying factors; IKZF1; cooperative changes;

    Sammanfattning : Acute lymphoblastic leukemia (ALL) is characterized by an accumulation of immature lymphoid cells in the bone marrow and is the most common cancer type in children. It is an immunophenotypically, morphologically, clinically, and genetically heterogeneous disorder that comprises several distinct subtypes. LÄS MER

  5. 4. Gene Expression Studies of Hematologic Malignacies

    Författare :Anna Andersson; Avdelningen för klinisk genetik; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 5. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation

    Författare :Jennie Håkansson; Linköpings universitet; []
    Nyckelord :Red junglefowl; behavioural differences; genetic relationships; captive populations; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Conservation of species is to a large extent carried out by zoos where animals are kept in small populations under protected conditions. The ultimate goal of such ex situ conservation programs is to eventually reintroduce the animals into natural habitats to provide support for the survival of the species. LÄS MER
