Thiazolidinedione Derivative Suppresses LPS-induced COX-2 Expression and NO Production in RAW 264.7 Macrophages
The present study was designed to investigate the inhibitory effect of 2,4 bis-[(4-ethoxyphenyl)azo] 5-(3-hydroxybenzylidene) thiazolidine-2,4-dione (TZD-OCH2CH3) on the cyclo-oxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in RAW 264.7 cells. The effects of TZD-OCH2CH3 on COX-2 and iNOS mRNA expression in LPS-activated RAW 264.7 cells ...

متن کاملArachidonic acid oxygenation by COX-1 and COX-2. Mechanisms of catalysis and inhibition.
Prostaglandins were discovered in human semen in 1930, but their low concentrations and instability precluded identification for nearly 30 years (for a brief historical review, see Ref. 1). Once they were identified, it was clear they arose from polyunsaturated fatty acids by a complex series of reactions involving oxygenation, cyclization, and the generation of five chiral centers from an achi...

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...
