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 کاملCooperation of cyclooxygenase 1 and cyclooxygenase 2 in intestinal polyposis.
Membrane arachidonic acid is converted by cyclooxygenase (COX) into prostaglandin (PG) G(2) and then to PGH(2) which is subsequently metabolized to PGE(2) by PGE synthase (PGES). Both COX-1 and COX-2 play critical roles in intestinal polyp formation, whereas COX-2 is also expressed in cancers of a variety of organs. Likewise, inducible microsomal PGES (mPGES-1) is expressed in several types of ...
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...
متن کاملOntogeny of cyclooxygenase-1 and cyclooxygenase-2 gene expression in ovine lung.
Prostacyclin is a key mediator of pulmonary vascular and parenchymal function during late fetal and early postnatal life, and its synthesis in whole lung increases during that period. The rate-limiting enzyme in prostacyclin synthesis in the developing lung is cyclooxygenase (COX). We investigated the ontogeny and cellular localization of COX-1 (constitutive) and COX-2 (inducible) gene expressi...
