  1. 16. Analysis of chromosomal rearrangements and gene copy number changes in breast cancer cells

    Författare :Pär Lundin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Genome changes in terms of numerical chromosomal aberrations and structural rearrangements, including deletions, amplifications and translocations, gradually accumulate in the genome during tumor development. These genomic changes are likely to play an important role in the process of tumor progression. LÄS MER

  3. 17. The Evolution of Sex Chromosomes and Dosage Compensation in Structurally Dynamic Butterfly Genomes

    Författare :Lars Höök; Niclas Backström; Elina Immonen; Beatriz Vicoso; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Dosage compensation; Sex-biased gene expression; Faster-Z; Lepidoptera; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Dimorphic sex chromosomes have evolved independently throughout evolution from initially homologous autosomes. Recombination suppression between the sex chromosomes causes one sex chromosome to degenerate, which will influence evolution of sex-linked genes. LÄS MER

  4. 18. Characterization of human chromosome 22 : cloning of breakpoints of the constitutional translocation t(11;22)(q23;q11) and detection of small constitutional delections by microarray CGH

    Författare :Isabel Tapia Paez; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Chromosome 22; t 11; 22 q23; q 11 ; inverted repeats palindromes; DiGeorge Velo-cardio-facial syndrome; array-CGH;

    Sammanfattning : Chromosome 22 is the second smallest human chromosome, composing approximately 1.5% of the genome. The short arm of this acrocentric chromosome harbors ribosomal genes and the long arm contains the protein coding genes. LÄS MER

  5. 19. Prognostic factors in squamous cell carcinoma of the head and neck, with emphasis on 11q13 rearrangements and cyclin D1 overexpression

    Författare :Jan Åkervall; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; audiologi; Otorinolaryngologi; auditive system and speech; audiology; head and neck; squamous cell carcinoma; genetics; prognosis; CCND1; chromosomes; cyclin D1; chemotherapy; Otorhinolaryngology; gene expression; hörsel- och talorganen;

    Sammanfattning : At present, clinical outcome or response to therapy can not be fully predicted in individual cases of squamous cell carcinoma of the head and neck (SCCHN). The overall aim of the present studies was to investigate potential prognostic factors, more closely related to the malignant progression of a tumor than the established markers, such as the TNM-classification system.

  7. 20. Genetic characterization of non-Hodgkin lymphomas using in situ hybridization

    Författare :Svetlana Lagercrantz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Myelodysplastic syndrome; non-Hodgkin lymphoma; fluorescencein situ hybridization; LAZ3BCL6 expression; chromosome rearrangements;

    Sammanfattning : Fluorescence in situ hybridization (FISH) has been shown to be a valuable and important technique in cytogenetics, as a complement to traditional banding analysis. This thesis focus on the characterization of chromosomal rearrangements in two hematological neoplasias, myelodysplastic syndrome (MDS) and non-Hodgkin lymphoma (NHL) using FISH. LÄS MER
