  2. 21. Tumor angiogenesis. Regulation of mural cell recruitment and endothelial sprouting

    Author : Alexandra Abramsson; Göteborgs universitet; []
    Keywords : Angiogenesis; tumor; retina; PDGF; VEGF; platelet-derived growth factor; guidance; vascular endothelial growth factor.;

    Abstract : The formation of new blood vessels is an inherent part of many physiological and pathological processes. Currently, there is a strong hope pathological situations like stroke, diabetic retinopathy and cancer may be affected by pharmacological regulators of blood vessel formation. READ MORE

  4. 22. Monitoring of neuroendocrine tumor patients undergoing systemic therapies

    Author : Olof Pettersson; Anders Sundin; Håkan Geijer; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Therapy monitoring; NET; neuroendocrine tumor; computed tomography; CT; PRRT; 177Lu-DOTATATE; TGR; tumor growth rate; theranostics; DOTATOC-PET CT; Radiology; Radiologi; Endokrinologi och Diabetologi; Endocrinology and Diabetology; Oncology; Onkologi;

    Abstract : Monitoring of neuroendocrine tumor (NET) patients undergoing systemic therapies is troublesome as biomarkers capable of detecting tumor responses have been difficult to establish. Changes in the sum of target lesion diameters are used to evaluate the effects of therapy according to the response evaluation criteria in solid tumors (RECIST 1.1). READ MORE

  5. 23. Immune modulation in serous epithelial ovarian cancer : focus on the role of tumor-derived exosomes

    Author : Alireza Labani Motlagh; Lucia Mincheva-Nilsson; Ola Winqvist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovarian cancer; EOC; HGSC; exosomes; NKG2D; MICA B; ULBP; DNAM-1; PVR; nectin-2; lncRNAs; immune suppression; anti-tumor immunity; NK-cell cytotoxicity; cytokines; Th1; Th2; T regulatory response; inflammation; tumor microenvironment;

    Abstract : Serous epithelial ovarian cancer (EOC) is a potent suppressor of the immune defense. Here, we studied interactions between EOC and the immune system that lead to escape from tumor immune surveillance. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 25. Hypoxia-Inducible Factors in Tumor Cell Differentiation and Tumor Vascularization

    Author : Alexander Pietras; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIF-2alpha; cancer; notch; angiogenesis; tumor-initiating cells; hypoxia; neuroblastoma; differentiation;

    Abstract : Mammalian cells, including tumor cells, adapt to hypoxia via stabilization of two transcription factors - Hypoxia-inducible factor (HIF)-1alpha and HIF-2alpha. Among other consequences, hypoxia is a main driving force behind angiogenesis. READ MORE
