Expression of cyclooxygenase-2 in melanocytic skin lesions by immunohistochemistry
Introduction: cyclooxygenase-2 (COX-2) is involved in pathogenesis of various tumors and possibly malignant skin tumors including malignant melanoma; however, there is not enough information about COX-2 expression in benign melanocytic lesions. In the present study we compared the expression levels of COX-2 in malignant melanoma and benign melanocytic lesions. Method: In this analytical study, ...
متن کاملThe expression of cyclooxygenase-1, cyclooxygenase-2 and 5-lipoxygenase in inflammatory muscle tissue of patients with polymyositis and dermatomyositis.
OBJECTIVE To describe cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) expression in muscle tissue in patients with idiopathic inflammatory myopathies (IIM) - dermatomyositis (DM) and polymyositis (PM) and to find out if any differences between affected and non-affected muscles detected by MRI exist. METHODS Samples of muscle tissue from 7 patients with dermatomyo...
متن کاملCyclooxygenase-2 (COX-2) in inflammatory and degenerative brain diseases.
Cyclooxygenase (COX) catalyses the first committed step in the synthesis of prostanoids, a large family of arachidonic acid metabolites comprising prostaglandins, prostacyclin, and thromboxanes, and is a major target of non-steroidal anti-inflammatory drugs (NSAIDs). COX exists as constitutive and inducible isoforms. COX-2 is the inducible isoform, rapidly expressed in several cell types in res...
متن کاملExpression of cyclooxygenase-1 and cyclooxygenase-2 in normal and pathological human oral mucosa.
Cyclooxigenase (COX) is the rate-limiting enzyme for the conversion of arachidonic acid (AA) to prostaglandins (PGs). Two isoforms of COX have been identified: COX-1 is constitutively expressed in many cells and is involved in cell homeostasis, angiogenesis and cell-cell signalling; COX-2 is not expressed in normal condition however it is strongly expressed in inflammation. The oral cavity is c...
متن کاملcyclooxygenase-2 expression in lymphoma in north-west of iran.
background: lymphomas are a group of malignancies affecting b, t and nk cells. cox-2 enzyme is one of the known inflammatory factors which increase in the inflammation process. increase in cox-2 expression inhibits apoptosis and increases tumor cells invasion and angiogenesis. increase in the cox-2 gene expression is seen in a group of cancers .specific cox-2 inhibition also can be beneficial i...
