  1. 16. 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

  2. 17. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

    Författare :Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; Switzerland Ecole Polytechnique Fédérale de Lausanne (EPFL); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biological Physics; Biologisk fysik;

    Sammanfattning : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. LÄS MER

  3. 18. Tumour evolution and novel biomarkers in breast cancer

    Författare :Jana Biermann; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; breast cancer; gene signature; molecular biomarkers; tumour clonality; genomic instability; Swedish haemangioma cohort;

    Sammanfattning : Several gene signatures have been proposed in the past two decades to improve outcome prediction for breast cancer patients and to guide treatment decisions. Current treatment guidelines, however, primarily focus on established clinicopathological features. LÄS MER

  4. 19. microRNAs: from biogenesis to organismal tracing

    Författare :Wenjing Kang; Marc Friedländer; Jens Lagergren; Ulf Ørom; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microRNA; microRNA biogenesis; taxonomical identification; high throughput sequencing; xenomiRs; RNA structure; high throughput screening; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : MicroRNAs (miRNAs) are short noncoding RNAs of around 22 nucleotides in length, which help to shape the expression of most mRNAs. Perturbation of miRNA expression has revealed a variety of defects in development, cell specification, physiology and behavior. LÄS MER

  5. 20. Novel Circulating and Tissue Biomarkers for Small Intestine Neuroendocrine Tumors and Lung Carcinoids

    Författare :Tao Cui; Valeria Giandomenico; Kjell Öberg; Apostolos V. Tsolakis; Marco Volante; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small intestine neuroendocrine tumors; lung carcinoids; Ma2 autoantibodies; immunohistochemistry; olfactory receptor 51E1; blood samples; antibody suspension bead array; 小肠神经内分泌肿瘤,肺类癌,Ma2自身抗体,免疫组化,嗅觉受体蛋白51E1, 血液样本,抗体悬浮磁珠阵列; Endokrinologi och Diabetologi; Endocrinology and Diabetology; Lung Medicine; Lungmedicin; Molecular Biology; Molekylärbiologi; Oncology; Onkologi;

    Sammanfattning : Small intestine neuroendocrine tumors (SI-NETs) and lung carcinoids (LCs) are relatively indolent tumors, which originate from neuroendocrine (NE) cells of the diffuse NE system. Metastases can spread before diagnosis. Thus, potential cures become unavailable, which entitles new biomarker development. LÄS MER
