  1. 1. Prostanoids and colorectal cancer

    Författare :Annika Gustafsson Asting; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer prostanoid receptors cyclooxygenase PGE2 transcription factors;

    Sammanfattning : Tumor disease is a main cause of death in Western countries and a most common malignancy is colorectal cancer (CRC). Growing tumors are dependent on interactions among several different cells as well as signaling pathways. LÄS MER

  2. 2. Prostaglandins and angiogenesis in experimental cancer

    Författare :Hans Axelsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; dorsal skin fold chamber; prostanoids; PGE2; indomethacin;

    Sammanfattning : Background and aim. Genes, proteins and pathways have been identified and suggested as potential targets in tumor angiogenesis, but current anti-angiogenic therapies have provided only modest benefits in survival of cancer patients. LÄS MER

  3. 3. Methodological studies of eicosanoid enzyme gene expression in vascular endothelium exposed to biomechanical stress

    Författare :Roya Doroudi; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostanoids; endothelium; quantitative RT-PCR; perfusion model; shear stress; intraluminal pressure; immediate-early genes;

    Sammanfattning : Prostaglandins are the major eicosanoids synthesized by vascular endothelial cells, and the vasculature is an important target organ for their bioactive metabolites. In vitro studies have shown that biomechanical forces are important regulators of vascular expression of prostanoid enzymes and release of metabolites. LÄS MER

  4. 4. An experimental study of mediators in allergic bronchoconstriction with focus on eicosanoids

    Författare :Ewa Selg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Leukotrienes; prostaglandins; histamine; guinea pig lung; ovalbumin; mast cell; cyclooxygenase; airway smooth muscle; COX inhibitors; NSAIDs;

    Sammanfattning : Mast cells have a central role in the inflammatory response in airways of both atopic and non-atopic asthmatics. The mast cell-derived mediators such as histamine, leukotriene C4 and prostaglandin D2, released upon activation of the cell, produce acute bronchoconstriction that is characteristic of the early asthmatic response (EAR), and contribute to the development of airway inflammation and hyperresponsiveness following the initial reaction.

  5. 5. Structure and expression of the TP and EP1 prostanoid receptor genes

    Författare :Björn Båtshake; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; neurofysiologi; Neurology; neuropsychology; neurophysiology;

    Sammanfattning : Prostanoids are ubiquitously distributed lipid signaling molecules derived from arachidonic acid, that exhibit numerous and diverse biological effects in a variety of physiological and pathophysiological conditions. The cell surface receptors for the prostanoids belong to the family of G protein-coupled receptors. LÄS MER
