Localization of cyclo-oxygenase-2 in human recurrent colorectal cancer.
AIM The aim of this paper is to examine COX-2 expression in human recurrent colorectal carcinoma tissues using immunohistochemistry and quantative real-time PCR (qPCR). METHODS Colon and rectal specimens were obtained from 26 patients with recurrent colorectal carcinomas. We examined COX-2 expression in human recurrent colorectal carcinoma tissues using immunohistochemistry and quantative rea...
متن کاملStructure of the human cyclo-oxygenase-2 gene.
Cyclo-oxygenase (Cox), a rate-limiting enzyme in the synthesis of prostanoids, is encoded by two genes, Cox-1 and Cox-2, which are differentially expressed and regulated. Human Cox-1 and -2 polypeptides share 61% primary sequence identity. While the expression of Cox-1 is maximal in quiescent cells. Cox-2 expression is induced by growth factors and cytokines. We have screened a human genomic li...
متن کاملEvaluation of cytotoxicity mechanism of two cyclo-oxygenase-2 inhibitors in leukemia cell line
Introduction: Leukemia is considered one of the main causes of death, and current chemotherapeutic agents are unable to provide optimal responses due to chemo-resistance. Therefore, there is a constant need for new drugs. Cyclooxygenase- 2 (COX-2) inhibitors can be helpful by reducing the necessary dose of routine chemotherapeutic drugs. Herein, we evaluated the cytotoxicity activity as well...
متن کاملCyclo-oxygenase 2 expression is associated with angiogenesis and lymph node metastasis in human breast cancer.
AIMS Cyclo-oxygenases 1 and 2 (COX-1 and COX-2) are key enzymes in prostaglandin biosynthesis. COX-2 is induced by a wide variety of stimuli, and present during inflammation. COX-2 overexpression has been observed in colon, head and neck, lung, prostate, stomach, and breast cancer. In colon and gastric cancer, COX-2 expression was associated with angiogenesis. The aim of this study was to deter...
متن کاملExpression and localization of cyclo-oxygenase isoforms in non-small cell lung cancer.
The beneficial effects of cyclo-oxygenase (COX) inhibitors in both colon cancer and adenomatous polyps suggest a role for the prostanoid pathway in epithelial malignancy. Although variable prostanoid synthesis in non-small cell lung cancer (NSCLC) has been demonstrated in freshly obtained tissue, COX messenger ribonucleic acid (mRNA) and protein localization in such tumours had not been investi...
