Dinoprostone 27-31 prostaglandin E receptor 2 Rattus norvegicus 47-50 11207665-7 2001 Our results suggest that prostaglandin E2 regulates the functions of synovial macrophages and fibroblasts through EP2 and EP4, which are induced by inflammatory stimuli in rats with adjuvant arthritis. Dinoprostone 25-41 prostaglandin E receptor 2 Rattus norvegicus 114-117 9950799-5 1999 Furthermore, butaprost (EP2 agonist) was inactive, 11-deoxy-PGE1 (EP4/EP2 agonist) was as effective as PGE2, and the PGE2 effect was abolished dose dependently by the selective EP4 antagonist AH-23848B, suggesting the involvement of EP4. Dinoprostone 103-107 prostaglandin E receptor 2 Rattus norvegicus 70-73 9950799-5 1999 Furthermore, butaprost (EP2 agonist) was inactive, 11-deoxy-PGE1 (EP4/EP2 agonist) was as effective as PGE2, and the PGE2 effect was abolished dose dependently by the selective EP4 antagonist AH-23848B, suggesting the involvement of EP4. Dinoprostone 117-121 prostaglandin E receptor 2 Rattus norvegicus 24-27 9950799-3 1999 PGE2 increased both parameters, peaking at 100 nM, an effect that was mimicked by forskolin and was abolished by 2",3"-dideoxyadenosine (an adenylate cyclase inhibitor) and was thus cAMP dependent, pointing to the involvement of EP2 or EP4. Dinoprostone 0-4 prostaglandin E receptor 2 Rattus norvegicus 229-232 9950799-5 1999 Furthermore, butaprost (EP2 agonist) was inactive, 11-deoxy-PGE1 (EP4/EP2 agonist) was as effective as PGE2, and the PGE2 effect was abolished dose dependently by the selective EP4 antagonist AH-23848B, suggesting the involvement of EP4. Dinoprostone 117-121 prostaglandin E receptor 2 Rattus norvegicus 70-73 9893949-9 1998 On the other hand, COX-2 expression was up-regulated by the macrophage-deactivating cytokine TGF-beta 1, by exogenous PGE2 itself, which acted through EP2 receptors linked to cyclic AMP generation, and by non steroidal anti-inflammatory drugs. Dinoprostone 118-122 prostaglandin E receptor 2 Rattus norvegicus 151-154 9930728-13 1999 Thus, the inhibitory effects of PGE2 on microglia are mediated by the EP2 receptor subtype, and the signaling mechanism of this effect is likely via cAMP. Dinoprostone 32-36 prostaglandin E receptor 2 Rattus norvegicus 70-73 9893949-10 1998 Interestingly, PGE2 utilized the same EP2 receptor-mediated signal transduction mechanism to down-regulate the expression of the inducible NO synthase and the production of NO. Dinoprostone 15-19 prostaglandin E receptor 2 Rattus norvegicus 38-41 9779823-3 1998 We now report that these actions by PGE2 are routed through cAMP via the PGE2, EP2 receptor. Dinoprostone 36-40 prostaglandin E receptor 2 Rattus norvegicus 79-82 9779823-3 1998 We now report that these actions by PGE2 are routed through cAMP via the PGE2, EP2 receptor. Dinoprostone 73-77 prostaglandin E receptor 2 Rattus norvegicus 79-82 9779823-15 1998 Overall, these results illustrate that much of the PGE2 action on the expression of COL, LO, and COX1 genes is mediated through the EP2 receptor and a subsequent increase in intracellular cAMP. Dinoprostone 51-55 prostaglandin E receptor 2 Rattus norvegicus 132-135 9440134-2 1997 The receptors for PGE2 have been classified into four pharmacological subtypes, EP1, EP2, EP3, and EP4, based on the responses to selective agonists and antagonists.

Dinoprostone 167-171 prostaglandin E receptor 2 Rattus norvegicus 36-39 9440134-6 1997 PGE2 and butaprost, an EP2 selective agonist, were effective in increasing the cAMP level in the COS-7 cell transfectants. Dinoprostone 0-4 prostaglandin E receptor 2 Rattus norvegicus 23-26 9034831-6 1997 Second, the inhibitory effect of PGE2 was mimicked by 11-deoxy-16,16-dm PGE2, a selective agonist at the PGE2 receptor subtype EP2, coupled to the activation of adenylyl cyclase, but not by sulprostone, a potent agonist at receptor subtypes EP3 and EP1, associated with an inhibition of adenylyl cyclase activity and intracellular Ca2+ elevation, respectively.

Dinoprostone 156-160 prostaglandin E receptor 2 Rattus norvegicus 469-472 9182946-7 1997 In conclusion, while the strong up-regulation of cyclooxygenase-2 expression by exogenous PGE2 appears to be mediated by EP2 receptors and cAMP, the limited down-regulation caused by anti-inflammatory drug treatments may be either due to arachidonic acid metabolites other than PGE2, or to PGE2 itself, acting through a distinct cAMP-independent signalling pathway.
