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

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Cytologi; cancerology; Cytology; BioArray Software Environment; BASE; Software; Open-source; Copy number; Gene expression; Microarray; BRCA2; BRCA1; Breast cancer; Hereditary cancer; oncology;

    Abstract : 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. 2. RNA Sequencing for Molecular Diagnostics in Breast Cancer

    Abstract : Breast cancer is the most common type of cancer in women and, in Sweden, is the most deadly second only to lung cancer. While treatment and diagnostic options have improved in the past decades and short- to mid-term survival is good, long-term survival is much poorer. READ MORE

  3. 3. Predictive markers for tamoxifen response in primary breast cancer

    Author : Maria Stendahl; Malmö Patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; General pathology; Cytologi; onkologi; prognosis; Cytology; oncology; cancerology; predictive marker; p27; cyclin D1; tamoxifen; PR; breast cancer; ER; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Abstract : It is well-known that a majority of breast cancers are hormone-dependent, making endocrine therapy an important adjuvant treatment after surgery. Susceptibility to endocrine treatment is determined by the presence of estrogen receptors (ER) and progesterone receptors (PR) in the tumors. READ MORE

  4. 4. Genetic characterization of malignant melanoma and breast cancer

    Author : Göran B Jönsson; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; microarray; inherited breast cancer; Melanoma; linkage analysis; cancer; Cytologi; cancerology; onkologi;

    Abstract : Malignant melanoma and breast cancer are common malignant diseases characterized by considerable heterogeneity with respect to genetics, histopathology, biology and clinical course. In breast cancer, two major susceptibility genes have been identified, BRCA1 and BRCA2, which account for a significant proportion of high-risk breast cancer families. READ MORE

  5. 5. Genetic factors in childhood cancer. Associations between tumors in childhood and adulthood, and prevalence of germline TP53 mutations

    Author : Susanne Magnusson; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood cancer; hereditary factors; breast cancer; survival; hereditary breast and ovarian cancer; hereditary non-polyposis colorectal cancer; familial malignant melanoma; BRCA1; BRCA2; mismatch repair; CDKN2A; familial risk; multiple childhood tumors; Li-Fraumeni syndrome; TP53; adrenocortical carcinoma; choroid plexus tumors; rhabdomyosarcoma;

    Abstract : The etiology of childhood cancer is largely unknown. Approximately 1-10% of all childhood tumors are associated with known cancer predisposition syndromes. However, the contribution may be underestimated due to the failure to detect patients with genetic susceptibility for cancer when relying on known family pattern and anomalies. READ MORE
