    Sammanfattning : Prostaglandin (PG) E2 is an eicosanoid derived from the polyunsaturated twenty carbon fatty acid arachidonic acid (AA). PGE2 has physiological as well as pathophysiological functions and is known to be a key mediator of inflammatory responses. LÄS MER

    Sammanfattning : We are unceasingly exposed to potentially harmful microorganisms. The battle against threatening infectious agents includes activation of both the innate and of the adaptive immune systems. LÄS MER

  3. 3. Cell signalling in cancer. A functional and immunochemical investigation of purinergic,adrenergic, nitrergic, and prostaglandin mediated signalling mechanisms in experimental and human cancer

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Gunnar Nylund; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adenosine-5´-triphosphate; colon cancer; extracellular acidification; melanoma; ; microphysiometer; nitric oxide; noradrenaline; prostaglandin E2; sarcoma; tumour cell; metabolism; uridine-5´-triphosphate;

    Sammanfattning : Disturbed cell signalling is a hallmark of the cancer cell, being one important mechanismbehind uncontrolled cell growth. In the current study, we have investigated cancer cellsignalling with the focus on some first messenger and/or their receptors, in the murine celllines, MCG 101, and K1735-M2, and the human colon cancer cell line, HT-29.

  4. 4. Regulation of prostaglandin E2 synthesis in human gingival fibroblasts

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Odontology

    Författare :Tülay Yucel-Lindberg; Karolinska Institutet.; Karolinska Institutet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostaglandin E2; cyclooxygenase; phospholipase A2 interleukin-1; tumor necrosis factor [alpha]; epidermal growth factor; protein kinase C; tyrosine kinases; human gingival fibroblasts;

    Sammanfattning : Prostaglandins, especially, prostaglandin E2 (PGE2) play an important role in inflammatory diseases such as rheumatoid arthritis and periodontitis. The aim of the present thesis was to study the production and the regulation of PGE2 with special reference to the key enzymes phospholipase A2 (PLA2) and cyclooxygenase (COX) at the rnRNA level in human gingival fibroblasts.

  5. 5. Prostaglandin E2 influences the gastrointestinal endocrine cell system in the rat

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Marjo Kapraali; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CCK; EC cells; ECL cells; endocrine cell system; glucagon; indomethacin; neurokinin A; neurotensin; prostaglandin E2; somatostatin;

    Sammanfattning : Previous studies suggest that prostaglandin E2 may interact with gastrointestinal endocrine cells. Our aim was to examine whether erogenous and endogenous prostaglandins - particularly prostaglandin E2 - influence the endocrine cell system in the rat gastrointestinal tract. LÄS MER
