  1. 1. Genomic profiling of breast cancer by microarray-based technology and bioinformatics

    Författare :Johan Staaf; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Survival; Prognostic predictor; Gene Expression; ERBB2; HER2; Microarray; Copy Number Analysis; CGH; aCGH; Amplification; Gene expression analysis;

    Sammanfattning : Cancer is a genetic disease that arises when a cell acquires unlimited growth potential through a series of mutational events, which target genes essential for normal cell control and maintenance. Breast cancer is one of the most frequent malignancies in women worldwide, and it is characterized by heterogeneous tumor biology, histological subtypes, variable prognosis and variable responsiveness to treatment.

  3. 2. MicroRNAs in HER2-Amplified Breast Cancer

    Författare :Inga Newie; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; miR-21; PAPD5; Breast Cancer; miR-4728; microRNA; ERBB2 HER2;

    Sammanfattning : Background: Breast cancer is the most common female malignancy and the leading cause of cancer-related deaths worldwide. Targeted therapy against the main biomarkers estrogen receptor alpha (ER) and human epidermal growth factor receptor 2 (HER2/ERBB2) have greatly improved mortality rates, but ab initio or acquired therapy resistance is common.

  4. 3. Molecular factors influencing epithelial-mesenchymal transition in breast cancer

    Författare :Gisela M A Nilsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breast cancer; epithelial-mesenchymal transition; c-erbB2; E-cadherin; NFI-C2; FoxF1; LOX;

    Sammanfattning : Epithelial-mesenchymal transition (EMT) is a developmental process defined by loss of epithelial characteristics and acquisition of mesenchymal phenotype. EMT or similar processes are also implicated in carcinoma cell invasion and the progression of breast carcinoma to metastasis. LÄS MER

  5. 4. Breast cancer : Multifocality, heterogeneity, and related genetic signatures

    Författare :Gyula Pekar; Dumanski Jan; Sapino Anna; Uppsala universitet; []
    Nyckelord :breast; breast cancer multifocality; molecular phenotypes; intertumoral heterogeneity; biobanking; gene copy number aberrations;

    Sammanfattning : Breast carcinoma often exhibits a complex subgross morphology and may occupy a large volume of the breast tissue and show unifocal, multifocal or diffuse growth patterns. Expression of estrogen- and progesterone receptors, HER2 overexpression, tumor grade, and proliferative activity allows us to classify breast carcinoma into molecular subgroups (Luminal A, Luminal B, HER2-type, triple negative, and basal-like).

  7. 5. Improving biomarker assessment in breast pathology

    Författare :Stephanie Robertson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The accuracy of prognostic and therapy-predictive biomarker assessment in breast tumours is crucial for management and therapy decision in patients with breast cancer. In this thesis, biomarkers used in clinical practice with emphasise on Ki67 and HER2 were studied using several methods including immunocytochemistry, in situ hybridisation, gene expression assays and digital image analysis, with the overall aim to improve routine biomarker evaluation and clarify the prognostic potential in early breast cancer.
