    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D tumor modeling; Spheroids; Cellulose Nano Fibrils; Layer by Layer; Extracellular matrix; Circulating Tumor Capturing; Pancreatic ductal adenocarcinoma PDAC ; 3D-tumörmodellering; Sfärer; Cellulosa; Lager-på-lager; Extracellulärmatris; Infångning av cirkulerande tumörceller; Mänskliga Duktala Adenocarcinom-Hepatocyter; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cancer represents a significant global public health challenge and ranks as the second mostcommon cause of death in the United States. The onset of cancer entails an initial phasewhere cells lose their polarity and disconnect from the normal basement membrane, allowingthem to form distinct three-dimensional (3D) configurations that interact with adjacent cellsand the surrounding microenvironment.

  4. 3. 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; []

    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

  5. 4. Basement membrane collagens in pancreatic cancer : novel stroma-derived tumor markers and regulators of cancer cell growth

    Författare :Daniel Öhlund; Malin Sund; Peter Naredi; Matthias Löhr; Umeå universitet; []
    Nyckelord :Pancreatic cancer; tumor marker; basement membrane; type IV collagen; type XVIII collagen; matrix metalloproteinase; integrin; autocrine loop; tumor stroma; kirurgi; Surgery;

    Sammanfattning : Background: Among the common malignancies, pancreatic cancer has the shortest long-term survival. The aggressive, rapid, and infiltrative growth pattern of pancreatic cancer, together with the lack of specific symptoms, often leads to late diagnosis. LÄS MER

  7. 5. Isolation of Circulating Tumor Cells with Acoustophoresis : Towards a biomarker assay for prostate cancer

    Författare :Eva Undvall; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Biomarkers; Cell separation; Circulating tumor cells CTCs ; Elastomeric particles; Microfluidics; Negative selection; Prostate Cancer;

    Sammanfattning : Microfluidics has emerged as an essential approach in the development of novel technological platforms to detect and isolate rare circulating tumor cells (CTCs) in the blood of cancer patients. Micro-scaled fluidic systems offer means to precisely control fluid flow. LÄS MER
