  1. 1. On the genetics of hereditary breast/ovarian cancer. BRCA1, BRCA2 and beyond

    Author : Annika Bergman; Göteborgs universitet.; University of Gothenburg.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN; MEDICINE; BRCA1; BRCA2; breast cancer; hereditary cancer; founder mutation; mutation analysis; linkage analysis; genome scan; BRCAX;

    Abstract : Breast cancer is the most common malignancy in women. Most of the breast cancers are sporadic with no apparent inheritance factor but about 5-10% is believed to be caused by an inherited predisposition. Aims: This thesis aimed at defining the BRCA1/2 mutation spectrum of the west Swedish population and specifically to characterize the BRCA1c. READ MORE

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

    University dissertation from KFS AB, Lund

    Author : Johan Vallon-Christersson; Lunds universitet.; Lund University.; [2005]
    Keywords : cancer; onkologi; Cytologi; cancerology; Cytology; BioArray Software Environment; BASE; Software; Open-source; Copy number; Gene expression; Microarray; BRCA2; BRCA1; Breast cancer; Hereditary cancer; oncology; MEDICIN; MEDICINE;

    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.

  3. 3. Hereditary Breast Cancer in South Sweden. Early findings from studies on the role of BRCA1

    University dissertation from Department of Oncology, University Hospital Lund, S-221 85 Lund, Sweden

    Author : Oskar Thor Johannsson; Lunds universitet.; Lund University.; [1997]
    Keywords : CGH; survival analysis; mRNA in situ hybridization; germline mutations; LOH; Breast neoplasm; BRCA1; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; MEDICIN; MEDICINE;

    Abstract : The thesis presents the results from investigations into the role of BRCA1 in hereditary cancer in South Sweden. Loss of heterozygosity (LOH) studies found loss of the wildtype allele of BRCA1 to be common in BRCA1 associated breast cancer, but due to the high degree of LOH on chr. READ MORE

  5. 5. Genetic polymorphisms, IGF-1, and oral contraceptive use in women from high-risk breast cancer families

    University dissertation from Department of Oncology, IKVL, Medical Faculty, Lund University

    Author : Maria Henningson; Lunds universitet.; Lund University.; [2010]
    Keywords : premenopausal women; familial breast cancer; htSNP; GSTP1; polymorphism; BRCA1; BRCA2; IGF-1; oral contraceptives; CYP17; GSTT1; GSTM1; MEDICIN; MEDICINE;

    Abstract : Breast cancer is the most common cancer among Swedish women, affecting more than 7000 women each year. About 5-10% of all breast cancers are hereditary, with a monogenic inheritance pattern, but only 2-4% are explained by germline mutations in BRCA1 or BRCA2. BRCA1/BRCA2 mutation carriers have a 60-80% risk of developing breast cancer. READ MORE
