  2. 1. Inhibition of PDGF receptor signaling in tumor stroma : Effects on interstitial hypertension, drug uptake and therapeutic response

    Author : Kristian Pietras; Sven Påhlman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PDGF; tumor; stroma; tyrosine kinase inhibitor; combination therapy; Onkologi; Oncology; Onkologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : The role of platelet-derived growth factor (PDGF) in malignancies involves both autocrine and paracrine stimulation of cells within the tumor. The interstitial fluid pressure (IFP) is one of the forces that govern the transvascular flow of fluids. READ MORE

  4. 2. Leukocytes in Angiogenesis : Learning from Transplanted Pancreatic Islets

    Author : Gustaf Christoffersson; Mia Phillipson; Kristian Pietras; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; pancreatic islet transplantation; islets of Langerhans; diabetes mellitus; leukocytes; neutrophils; macrophages; pericytes; MMP-9; VEGF-A; Medical Science; Medicinsk vetenskap;

    Abstract : Angiogenesis, the growth of new blood vessels, is a complex process involving several cell types and molecular signals. Excessive vascular growth is a problem in tumors, and insufficient vascularization hampers the function of transplanted insulin-producing pancreatic islets. READ MORE

  5. 3. Cellular Origin and Development of Glioma

    Author : Nanna Lindberg; Lene Uhrbom; Bengt Westermark; Kristian Pietras; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; brain tumor; PDGF; RCAS TV-A; cell of origin; glial cell; oligodendrocyte progenitor cell; DNA repair; homology-directed repair; RAD51; angiogenesis; histidine-rich glycoprotein; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; Molecular Medicine; molekylär medicin genetik och patologi ;

    Abstract : Gliomas are the most common primary tumors of the central nervous system believed to arise from glial cells. Invasive growth and inherent propensity for malignant progression make gliomas incurable despite extensive treatment. READ MORE

  6. 4. Type IV collagen in breast and colorectal cancer : a potential biomarker of metastatic disease

    Author : Moa Lindgren; Hanna Nyström; Ingrid Ljuslinder; Malin Sund; Kristian Pietras; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; colorectal liver metastases; breast cancer; breast cancer metastases; tumor marker; biomarker; stroma; type IV collagen;

    Abstract : Background: Metastatic colorectal cancer (mCRC) and metastatic breast cancer (mBC) are two leading causes of cancer-related mortality worldwide. Early detection of metastatic disease is critical, and sensitive, easily accessed and cost-effective biomarkers that can diagnose mBC and mCRC at an early stage would have high clinical value.

  7. 5. Tumor instructed normal tissue : studies of potential extratumoral biomarkers and therapeutic targets in prostate cancer

    Author : Maria Nilsson; Sofia Halin Bergström; Anders Bergh; Kristian Pietras; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; biomarkers; tumor-instructed normal tissue; extra cellular matrix; macrophages; LOX; HO-1; MSMB; Pathology; patologi;

    Abstract : Prostate cancer is the most common cancer in men in Sweden and but luckily the majority of the patients will carry on their life without any consequences from the disease. Unfortunately, some will develop aggressive tumors and eventually die. READ MORE
