Application

L-798106, a selective prostanoid receptor EP3 antagonist, is used in prostanoid receptor signaling studies that regulate COX-2 levels and the central excitatory effects of PGE(2) on PVN neurons.

Biochem/physiol Actions

L-798106 was among the first prostanoid receptor EP3-selective antagonists. It has been used in multiple studies to tease out EP3 agonist activity, both in vitro and in vivo. It successfully blocks the actions of sulprostone, an EP3-selective agonist, and it helped show that the vascular contraction effect of PGE2 is due to its prostanoid EP3 agonist activity.

During periodontitis and orthodontic tooth movement, periodontal vasculature is severely impaired, leading to a hypoxic microenvironment of periodontal cells. However, the impact of hypoxia on periodontal cells is poorly defined. The present study investigates responses of cocultured endothelial cells (ECs)

Cyclooxygenase-2 (COX-2) is constitutively expressed and highly regulated in the thick ascending limb (TAL). As COX-2 inhibitors (Coxibs) increase COX-2 expression, we tested the hypothesis that a negative feedback mechanism involving PGE(2) EP3 receptors regulates COX-2 expression in the TAL.

The mechanisms by which prostanoids contribute to the maintenance of whole body water homeostasis are complex and not fully understood. The present study demonstrates that an EP3-dependent feedback mechanism contributes to the regulation of water homeostasis under high-salt conditions. Rats

Whereas few studies have dealt with the central sympathoexcitatory action of the inflammatory prostanoid prostaglandin E2 (PGE2), there is no information on the expression and cardiovascular function of different PGE2 (EP) receptors in one of the major cardiovascular-regulating nuclei, the
