Cyclo-oxygenase-2 (COX-2) expression at the site of recent myocardial infarction: friend or foe?
BACKGROUND Cyclo-oxygenase-2 (COX-2) is induced in cardiomyocytes only in response to stress, such as ischaemia. OBJECTIVE To assess COX-2 expression at the site of recent myocardial infarction. METHODS COX-2 expression was evaluated by specific immunostaining in cardiomyocytes from 23 subjects who died 10-60 days after acute myocardial infarction. The relation between COX-2 myocardial expr...
متن کاملIncreased cyclooxygenase-2 (COX-2) expression is associated with chemotherapy resistance and outcome in ovarian cancer patients.
BACKGROUND Cyclooxygenase-2 (COX-2) expression is associated with aggressive clinicopathological parameters and unfavourable prognosis in several human malignancies. The aim of this study was to investigate the expression of COX-2 and its association with clinicopathological parameters, response to treatment, and clinical outcome in ovarian cancer patients. PATIENTS AND METHODS COX-2 expressi...
متن کاملRole of immunohistochemical cyclo-oxygenase-2 (COX-2) and osteocalcin in differentiating between osteoblastomas and osteosarcomas.
BACKGROUND/AIMS Differential diagnosis between aggressive osteoblastoma and low grade osteosarcoma may be very difficult or even impossible on a small biopsy. This study was designed to assess the usefulness of immunoexpression of COX-2 and osteocalcin in the differential diagnosis of the two tumour types. METHODS Immunostaining of COX 2 and osteocalcin were studied in 9 osteoblastomas and 30...
متن کاملClinical resistance to platinum chemotherapy in ovarian cancer
Platinum drugs are the most active agents in ovarian cancer. Their cytotoxicty results from DNA crosslinking. High tumour response rates are seen, but 80 % of patients relapse. Major mechanisms of platinum resistance in patients remain to be established. We have studied DNA interstrand crosslinking and its repair in response to ex vivo treatment with cisplatin in forty patients with ovarian can...
متن کاملEvaluation of Expression of EGFR, HER-2 and COX-2 in Colorectal Cancer
Background and objective: EGFR and HER-2 are two members of ERbB/HER family of Type I Transmembrane growth factor receptors. Cox2 is an enzyme responsible for the conversion of arachidonic acid to prostaglandins, which has a major role in angiogenesis and can modelate tumor growth. The aim of this study was to determine the level of expression of EGFR, HER-2 and Cox2 in colorectd cancer. Mater...
