COX-1 and COX-2 products in the gut: therapeutic impact of COX-2 inhibitors.
Despite the considerable range of newly identified disease modifying approaches to the control of the inflammatory process reported over the past 10–20 years, only a few have yet gained widespread clinical acceptance. In contrast, the very recent advent of the class of anti-inflammatory agents termed COX-2 selective inhibitors is already having a significant impact on current clinical prescribi...

متن کاملCOX-1 vs. COX-2 as a determinant of basal tone in the internal anal sphincter.
Prostanoids, produced endogenously via cyclooxygenases (COXs), have been implicated in the sustained contraction of different smooth muscles. The two major types of COXs are COX-1 and COX-2. The COX subtype involved in the basal state of the internal anal sphincter (IAS) smooth muscle tone is not known. To identify the COX subtype, we examined the effect of COX-1- and COX-2-selective inhibitors...
متن کاملCOX-2-derived prostacyclin modulates vascular remodeling.
Suppression of prostacyclin (PGI2) biosynthesis may explain the increased incidence of myocardial infarction and stroke which has been observed in placebo controlled trials of cyclooxygenase (COX)-2 inhibitors. Herein, we examine if COX-2-derived PGI2 might condition the response of the vasculature to sustained physiologic stress in experimental models that retain endothelial integrity. Deletio...
متن کاملInduction of COX - 2 and down - regulation of COX - 1 expression by LPS control prostaglandin E 2 production in astrocytes *
Background: The relative contribution of COX2 and COX-1 to prostanoid formation under neuroinflammation is complex. Results: LPS induced COX-2 and mPGES1 but down-regulated COX-1 and TS in astroglia. These effects accounted for high production of PGE2. Conclusion: PGE2 after LPS results from the coordinated COX-2 up-regulation and COX-1 down-regulation in astrocytes. Significance: Changes in CO...
