The cyclooxygenase (COX) enzymes catalyze a key step in the conversion of arachidonate to PGH2, the immediate substrate for a series of cell specific prostaglandin and thromboxane synthases. Prostaglandins play critical roles in numerous biologic processes, including the regulation of immune function, kidney development, reproductive biology, and(More)
BACKGROUND & AIMS The cyclooxygenase 2 (COX-2) and ErbB/HER pathways are important modulators of cancer cell growth. We sought to determine the effects of treatment with a specific COX-2 inhibitor and/or a monoclonal antibody against the ErbB receptor subtype HER-2/neu on carcinoma cell growth. METHODS A cell-proliferation assay was used to determine the(More)
