  1. 21. Functional and Molecular Characterization of BRCA1 and BRCA2 Associated Breast Cancer

    Sammanfattning : This doctoral dissertation is based on five appended papers primarily concerned with three main topics, namely: the functional characterization of specific and clinically relevant perturbations found in BRCA1 ? one of the major breast cancer susceptibility genes; the use of microarray technologies for molecular characterization of hereditary breast tumor samples from a genomic perspective; and finally, the development of software to address some of the logistical problems of data analysis and management that arise when utilizing microarrays. Results obtained from the work presented herein demonstrate the following: that transcription az says can aid in the characterization of C-terminal missense mutations but that it may not be possible to unambiguously characterize variants with a yeast-based assay alone; that a naturally occurring C-terminal germline mutation in BRCA1 encodes a protein with apparent temperature-dependant functional properties; that open-source software can provide comprehensive solutions to meet data management needs of microarray experimenters; that BRCA1 and BRCA2 associated breast tumors exhibit markedly different copy number aberrations when compared to each other as well as to sporadic tumors; and that gene expression profiling in BRCA1 and BRCA2 associated breast tumors reveals specific gene expression patterns.

  2. 22. Molecular Cytogenetics in Sporadic Breast Cancer

    Författare :Karin Rennstam; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; oncology; Cytology; Cytologi; cancer; gene expression; gene amplification; tumor development; cDNA microarray; fluorescence in situ hybridization FISH ; breast cancer; comparative genomic hybridization CGH ; cancerology; ERBB2;

    Sammanfattning : In recent time breast cancer has become the most common form of female cancer in the western world. It has been estimated that the lifetime risk of women falling ill from the disease is 10%. The number of patients diagnosed each year has been increasing steadily since the 1970s. LÄS MER

  3. 23. Cancer Immunotherapy : A Preclinical Study of Urinary Bladder Cancer

    Författare :Christina Ninalga; Thomas Tötterman; Magnus Essand; Timothy Ratliff; Uppsala universitet; []
    Nyckelord :Medicine; immunotherapy; bladder carcinoma; cancer; CpG ODNs; Adenoviral vector; CD40L; TRANCE; Lymphotactin; IL2; IL15; Medicin;

    Sammanfattning : Bacillus Calmette Guérin (BCG), or attenuated Mycobacterium bovis, is the gold standard of immunotherapy in the clinic to treat superficial bladder cancer. However, setbacks remain due to a high recurrence rate, side effects, and BCG-refractory disease. LÄS MER

  4. 24. The extent of gynaecological cancer : Evaluation, outcome and quality of life

    Författare :Björg Jónsdottir; Karin Stålberg; Inger Sundström Poromaa; Håkan Ahlström; Päivi Kannisto; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovarian cancer; endometrial cancer; cytoreductive surgery CRS ; PET MRI; MRI; Peritoneal cancer index PCI ; myometrial invasion MI ; quality of life.; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The overall aim of this thesis was to enhance treatment planning for gynaecological cancer patients and identify women that are more likely to have impaired quality of life (QoL) after treatment. In a retrospective cohort study on ovarian cancer, the peritoneal cancer index (PCI) was examined in relation to incomplete cytoreductive surgeries (CRS) and surgical complications (n=167).

  5. 25. Targeting NOX2 in cancer

    Författare :Ebru Aydin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; reactive oxygen species; immunotherapy; nox2; nk cells; melanoma; histamine; metastasis; leukemia; aml; cml; kras; mpd;

    Sammanfattning : Reactive oxygen species (ROS) are short-lived, toxic derivatives of oxygen that are produced during mitochondrial respiration and by NADPH oxidases (NOX). By enzymatically generating ROS, the myeloid cell NOX2 plays a critical role in defense against bacteria and other microorganisms. LÄS MER
