  1. 31. Estrogen receptor alpha and beta in breast cancer - gene expression profiles and clinical implications

    Författare :Sofia Gruvberger; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk biologi; oncology; cancerology; Cytologi; onkologi; cancer; Cytology; artificial neural networks; gene expression profiling; microarray; tamoxifen; adjuvant endocrine therapy; ER; estrogen receptor beta; Breast cancer; estrogen receptor alpha; Clinical biology;

    Sammanfattning : Breast cancer is the most common malignancy in women in the Western world with about 10% of women developing breast cancer during their lifetime, of which one third will eventually succumb to the metastatic form of the disease. Breast cancer arises from the epithelial cells of the breast mammary gland, but the mechanisms involved in tumor initiation, progression, and metastasis are still not fully understood. LÄS MER

  3. 32. Laminins and Fibulins in Bone Marrow

    Författare :Yu-Chen Gu; Institutionen för experimentell medicinsk vetenskap; []

    Sammanfattning : Development of hematopoietic cells in bone marrow takes place in association with the hematopoietic microenvironment. Extracellular matrix (ECM) molecules and stromal cells in bone marrow provide a structural environment for hematopoietic cells, but they also directly influence proliferation, differentiation and migration of cells by signal transduction mediated by ligand binding to cell surface adhesion receptors.

  5. 34. On the Role of Polyamines in Apoptosis

    Författare :Cecilia Hegardt; Bröstcancer-genetik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SSAT; DENSPM; spermine; polyamines; mitochondrial membrane potential; cytochrome c; caspase; flow cytometry; Jurkat cells; mouse thymocytes; thymus in vivo; programmed cell death; Dexamethasone-induced apoptosis; Fas-induced apoptosis; AdoMetDC; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; Clinical biology; Klinisk biologi; Animal physiology; Djurfysiologi;

    Sammanfattning : Apoptosis is a kind of death that is best described as cellular suicide and it is important for normal tissue homeostasis. The process can be induced by a number of different stimuli and the dying cell goes through a defined pathway terminating in typical biochemical and morphological alterations of the cell. LÄS MER

  7. 35. Alkaline Sphingomyelinase; A Potential Inhibitor in Colorectal Carcinogenesis

    Författare :Erik Hertervig; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Cytologi; cancerology; oncology; Cytology; Gastroenterologi; Gastro-enterology; HT-29; MIN mouse; FAP; colorectal cancer; human; alkaline sphingomyelinase;

    Sammanfattning : Sphingomyelin (SM) is present both in eucaryotic cells and the diet. Sphingomyelinase (SMase) hydrolyses SM and generates ceramide that has been implicated in the regulation of cell growth, differentiation and apoptosis. Previously a SMase with alkaline pH optimum was identified in the intestinal tract. LÄS MER
