Recent studies indicate an expression of mitogen-inducible cyclooxygenase (COX-2) in gastric mucosa. Rebamipide, a mucoprotective agent enhances prostaglandin (PG) synthesis. The present study was designed to clarify the mechanism for rebamipide-induced mucosal protection. Male Sprague-Dawley rats were administered 5, 15, or 50 mg/kg/day rebamipide for 14 days. The expression of constitutive cy...
Lipopolysaccharide is an inflammatory agent and interleukin-1 is a cytokine. Their pro-inflammatory effects may be mediated by prostanoids produced by inducible cyclooxygenase-2. The aim of this study was to determine the prostanoids produced by lipopolysaccharide and interleukin-1 stimulated enterocytes through the cyclooxygenase-1 and 2 pathways. Cultured enterocytes were stimulated with lipo...
A substantial amount of evidence has proposed an important role for Cyclooxygenase-2 (COX-2) enzyme in brain diseases and affiliate disorders. The purpose of this research was studying the effects of COX-2 selective inhibition on haloperidol-induced catatonia in an animal model of drug overdose and Parkinson’s disease (PD). In this study, the effect of acute and Sub-chronic oral administration ...
Colorectal cancer is the third most common cancer world wide and has been occurred more in developing regions. The use of conventional chemotherapy agents may lead to various adverse effects. Therefore, it is required to find the potential drug for anticancer from alternative source of natural product including mangrove plants. The present study was conducted to determine the anticancer activit...
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, ...

background: the omega-3 (ω-3) fatty acid eicosapentaenoic acid (epa) is currently used in the clinic as a nutritional supplement to improve infertility, particularly in women with polycystic ovarian syndrome (pcos).objective: the present study was designed to investigate the effect of epa on insulin-like growth factor 1 (igf-1) and cyclooxygenase 2 (cox-2) gene expression in primary cultured gr...
Background: Transitional Cell Carcinoma (TCC) is the most common type of urinary bladder cancer. Cyclooxygenase-2 (COX-2), a key enzyme in prostaglandins biosynthesis, has been introduced as a new candidate for targeted therapy in this cancer. In this study, we investigated the expression of COX-2 in urinary bladder TCCs and its relationship with clinicopathological parameters such as tumor gra...
