Prostaglandin E Receptors: Cell surface receptors which bind prostaglandins with a high affinity and trigger intracellular changes which influence the behavior of cells. Prostaglandin E receptors prefer prostaglandin E2 to other endogenous prostaglandins. They are subdivided into EP1, EP2, and EP3 types based on their effects and their pharmacology.

EP2 Subtype Prostaglandin E Receptors: A subtype of prostaglandin E receptors that specifically couples to GS ALPHA GTP-BINDING PROTEIN SUBUNITS and subsequently activates ADENYLATE CYCLASE.

Rat hepatocytes have previously been reported to possess prostaglandin E₂ receptors of the EP₃-type (EP₃-receptors) that inhibit glucagonstimulated glycogenolysis by decreasing cAMP. Here, the isolation of a functional EP₃ϐ receptor cDNA clone from a rat hepatocyte cDNA library is reported. This clone can be translated into a 362-amino-acid protein, that displays over 95% homology to the EP₃ϐ receptor from mouse mastocytoma. The amino- and carboxy-terminal region of the protein are least conserved. Transiently transfected HEK 293 cells expressed a single binding site for PGE₂ with an apparent Kd of 15 nM. PGE₂ | PGF₂α | PGD₂ competed for [³H]PGE₂ binding sites as did the EP₃ receptor agonists M&B 28767 = sulprostone | misoprostol but not the EP₁ receptor antagonist SC 19220. In stably transfected CHO cells M&B 28767 | sulprostone = PGE₂ | misoprostol | PGF₂α inhibited the forskolin-elicited cAMP formation. Thus, the characteristics of the EP₃ϐ receptor of rat

article{052b0b73-d88d-45b5-8981-e6d6bbe47eb8, abstract = {hEP4-R (human prostaglandin E2 receptor, subtype EP4) is a Gs-linked heterotrimeric GPCR (G-protein-coupled receptor). It undergoes agonist-induced desensitization and internalization that depend on the presence of its C-terminal domain. Desensitization and internalization of GPCRs are often linked to agonist-induced b-arrestin complex formation, which is stabilized by phosphorylation. Subsequently b-arrestin uncouples the receptor from its G-protein and links it to the endocytotic machinery. The C-terminal domain of hEP4-R contains 38 Ser/Thr residues that represent potential phosphorylation sites. The present study aimed to analyse the relevance of these Ser/Thr residues for agonist-induced phosphorylation, interaction with b-arrestin and internalization. In response to agonist treatment, hEP4-R was phosphorylated. By analysis of proteolytic phosphopeptides of the wild-type receptor and mutants in which groups of Ser/Thr residues had ...

Prostaglandin E2 receptor 1 (EP1) is a 42kDa prostaglandin receptor encoded by the PTGER1 gene. EP1 is one of four identified EP receptors, EP1, EP2, EP3, and EP4 which bind with and mediate cellular responses principally to prostaglandin E2) (PGE2) and also but generally with lesser affinity and responsiveness to certain other prostanoids (see Prostaglandin receptors). Animal model studies have implicated EP1 in various physiological and pathological responses. However, key differences in the distribution of EP1 between these test animals and humans as well as other complicating issues make it difficult to establish the function(s) of this receptor in human health and disease. The PTGER1 gene is located on human chromosome 19 at position p13.12 (i.e. 19p13.12), contains 2 introns and 3 exons, and codes for a G protein coupled receptor (GPCR) of the rhodopsin-like receptor family, Subfamily A14 (see rhodopsin-like receptors#Subfamily A14). Studies in mice, rats, and guinea pigs have found EP1 ...

Colorectal cancer (CRC) continues to be a major cause of morbidity and mortality. Although the factors underlying CRC development and progression are multifactorial, there is an important role for tumor-host interactions, especially interactions with myeloid cells. There is also increasing evidence that cyclooxygenase-derived prostaglandins are important mediators of CRC development and growth. Although prevention trials with either nonselective NSAIDs or COX-2 selective agents have shown promise, the gastrointestinal or cardiovascular side effects of these agents have limited their implementation. The predominant prostaglandin involved in CRC pathogenesis is PGE2. Since myeloid cells express high levels of the PGE2 receptor subtype, EP4, we selectively ablated EP4 in myeloid cells and studied adenoma formation in a mouse model of intestinal adenomatous polyposis, ApcMin/+ mice. ApcMin/+mice with selective myeloid cell deletion of EP4 had marked inhibition of both adenoma number and size, with ...

Blockade of prostaglandin (PG) production by COX inhibitors is the treatment of choice for inflammatory pain but is also prone to severe side effects. Identification of signaling elements downstream of COX inhibition, particularly of PG receptor subtypes responsible for pain sensitization (hyperalgesia), provides a strategy for better-tolerated analgesics. Here, we have identified PGE2 receptors of the EP2 receptor subtype as key signaling elements in spinal inflammatory hyperalgesia. Mice deficient in EP2 receptors (EP2-/- mice) completely lack spinal PGE2-evoked hyperalgesia. After a peripheral inflammatory stimulus, EP2-/- mice exhibit only short-lasting peripheral hyperalgesia but lack a second sustained hyperalgesic phase of spinal origin. Electrophysiological recordings identify diminished synaptic inhibition of excitatory dorsal horn neurons as the dominant source of EP2 receptor-dependent hyperalgesia. Our results thus demonstrate that inflammatory hyperalgesia can be treated by ...

The underlying mechanisms of protein sorting in polarized epithelial cells are poorly understood. Several studies have determined membrane targeting of G protein-coupled receptors (GPCRs) using epithelial cells such as Madin-Darby canine kidney (MDCK) cells. Polarized epithelial cells are composed of apical and basolateral plasma membrane domains with specific protein compositions separated by tight junctions. Purinergic, muscarinic, and adrenergic receptors are a few examples of GPCRs that have been shown to localize to specific membranes in MDCK cells. The current work seeks to determine the differences in subcellular localization of the human prostaglandin E2 receptors. The EP receptors are all GPCRs, which differ in their second messenger pathways. The EP3 receptor is unique in that it has eight different isoforms that differ in the lengths of the carboxyl tail. The EP3 isoforms, as well as the EP2 and EP4 receptors, have distinct properties, including different agonist-induced ...

A cDNA that when expressed has the binding and functional characteristics of the pharmacologically defined EP2 prostaglandin (PG) receptor [Cardiovasc. Drug Rev. 11:165-179 (1993)] has been cloned from a human placenta library. This clone, known as Hup-4, encodes a protein of 358 amino acids that has only approximately 30% overall identity with other PG receptors, including mouse and human clones that have been designated as EP2 receptors [J. Biol. Chem. 268:7759-7762 (1993); Biochem. Biophys. Res. Commun. 197:263-270 (1993)]. In COS-7 cells transfected with Hup-4, PGE2 stimulated the formation of cAMP with an EC50 of approximately 50 nM. The EP2-selective agonists AH13205 and butaprost were also active, with EC50 values in the range of 2-6 microM. The order of potency of PGs for competition with binding of [3H]PGE2 to membranes prepared from COS-7 cells transfected with Hup-4 was PGE2 , or = PGE1 , 16,16-dimethyl-PGE2 , or = 11-deoxy-PGE1 , butaprost , AH13205 , 19(R)-OH-PGE2.

Systemic inflammation, which results from the massive release of proinflammatory molecules into the circulatory system, is a major risk factor for severe illness, but the precise mechanisms underlying its control are not fully understood. We observed that prostaglandin E2 (PGE2), through its receptor EP4, is down-regulated in human systemic inflammatory disease. Mice with reduced PGE2 synthesis develop systemic inflammation, associated with translocation of gut bacteria, which can be prevented by treatment with EP4 agonists. Mechanistically, we demonstrate that PGE2-EP4 signaling acts directly on type 3 innate lymphoid cells (ILCs), promoting their homeostasis and driving them to produce interleukin-22 (IL-22). Disruption of the ILC-IL-22 axis impairs PGE2-mediated inhibition of systemic inflammation. Hence, the ILC-IL-22 axis is essential in protecting against gut barrier dysfunction, enabling PGE2-EP4 signaling to impede systemic inflammation. ...

TY - JOUR. T1 - Differential mRNA expression of prostaglandin receptor subtypes in macrophage activation. AU - Hubbard, Neil. AU - Lee, S. H.. AU - Lim, D.. AU - Erickson, Kent L. PY - 2001. Y1 - 2001. N2 - Assessing the regulation of macrophage receptors for prostaglandin (PGE2) is essential to understanding the control which that potent lipid mediator has in modulating macrophage activities. The purpose of this study was to assess the differential mRNA expression of PGE2 receptor subtypes (EP) during macrophage exposure to activating and transducing agents. RAW 264.7 macrophages constitutively expressed mRNA for EP2, EP3 and EP4 receptor subtypes. Messenger RNA for EP4 was expressed at a much higher level when compared to EP2 in unstimulated macrophages as assessed by kinetic quantitative RT-PCR. When macrophages were stimulated with LPS, EP2 mRNA levels were 12-fold higher when compared to unstimulated macrophages, while EP4 mRNA remained unchanged. Conversely, mRNA levels of both EP2 and EP4 ...

Prostaglandin(PG) D,SUB,2,/SUB, and PGE,SUB,2,/SUB, are major cyclooxygenase metabolites of arachidonic acid produced during allergic reactions including asthma. However, the role of PGD,SUB,2,/SUB, and PGE,SUB,2,/SUB, in allergic inflammation has long been ambiguous. This is partly because non-steroidal anti-inflammatory drugs that inhibit prostanoid synthesis are generally ineffective in allergic disorders. Both PGs exert their actions by acting on G-proteincoupled receptors; PGD,SUB,2,/SUB, acts at the PGD receptor(DP), PGE,SUB,2,/SUB, acts at four subtypes of PGE receptor, EP1 to EP4. To dissect the roles of PGD,SUB,2,/SUB,-DP pathway and each PGE,SUB,2,/SUB,-EP pathway in allergic reactions, we subject mice deficient in DP, EP1, EP2, EP3 and EP4 receptor individually to ovalbumin-induced allergic asthma as a model of type I allergy. These studies have revealed that there are opposing actions between two prostanoid pathways in allergic reactions; PGD,SUB,2,/SUB,-DP pathway and ...

Prostaglandin receptors or prostanoid receptors represent a sub-class of cell surface membrane receptors that are regarded as the primary receptors for one or more of the classical, naturally occurring prostanoids viz., prostaglandin D2, (i.e. PGD2), PGE2, PGF2alpha, prostacyclin (PGI2), thromboxane A2 (TXA2), and PGH2.[1] They are named based on the prostanoid to which they preferentially bind and respond, e.g. the receptor responsive to PGI2 at lower concentrations than any other prostanoid is named the Prostacyclin receptor (IP). One exception to this rule is the receptor for thromboxane A2 (TP) which binds and responds to PGH2 and TXA2 equally well. All of the prostanoid receptors are G protein-coupled receptors belonging to the Subfamily A14 of the rhodopsin-like receptor family except for the Prostaglandin DP2 receptor which is more closely related in amino acid sequence and functionality to chemotactic factor receptors such as the receptors for C5a and leukotriene B4.[2] Prostanoid ...

Collagen type I production decreases with aging, leading to wrinkles and impaired skin function. Prostaglandin E2 (PGE2), a lipid-derived signaling molecule produced from arachidonic acid by cyclo-oxygenase, inhibits collagen production and induces matrix metallopeptidase 1 (MMP1) expression by fibroblasts in vitro. PGE2-induced collagen expression inhibition and MMP1 promotion are aging mechanisms. This study investigated the role of E-prostanoid 1 (EP1) in PGE2 signaling in normal human dermal fibroblasts (NHDFs). When EP1 expression was inhibited by EP1 small interfering RNA (siRNA), there were no significant changes in messenger RNA (mRNA) levels of collagen, type I, alpha 1 (COL1A1)/MMP1 between siRNA-transfected NHDFs and siRNA-transfected NHDFs with PGE2. This result showed that EP1 is a PGE2 receptor. Extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation after PGE2 treatment significantly increased by ~2.5 times. In addition, PGE2 treatment increased the intracellular Ca2+

We reported recently that interleukin (IL)-1β exposure resulted in a prolonged increase in MUC5AC mucin production in normal, well differentiated, human tracheobronchial epithelial (NHTBE) cell cultures, without significantly increasing MUC5AC mRNA (Am J Physiol 286:L320-L330, 2004). The goal of the present study was to elucidate the signaling pathways involved in IL-1β-induced MUC5AC production. We found that IL-1β increased cyclooxygenase-2 (COX-2) mRNA expression and prostaglandin (PG) E2 production and that the COX-2 inhibitor celecoxib suppressed IL-1β-induced MUC5AC production. Addition of exogenous PGE2 to NHTBE cultures also increased MUC5AC production and IL-1β-induced Muc5ac hypersecretion in tracheas from wild-type but not from COX-2-/- mice. NHTBE cells expressed all four E-prostanoid (EP) receptor subtypes and misoprostol, an EP2 and EP4 agonist, increased MUC5AC production, whereas sulprostone, an EP1 and EP3 agonist, did not. Furthermore, specific protein kinase A (PKA) ...

Eight heptahelical receptors have been characterized for prostaglandin (PG) D2, PGE2, PGF2α, prostacyclin and thromboxane A2. They share a sequence identity of 40%. All of them have potential N-glycosylation sites. The current study analysed the role of the two N-glycosylation sites in the rat EP3β-subtype PGE2 receptor for protein folding and sorting. The N-glycosylation consensus sequences were eliminated by site-directed mutagenesis and receptors expressed in HEK-293 cells. Both potential N-glycosylation sites were used. Their joint elimination resulted in the synthesis of a receptor protein with full binding competence, biological activity and no reduction of affinity; however, the half-life of the non-glycosylated receptor was slightly reduced. Ligand binding to intact stably transfected cells and confocal laser microscopic immunocytochemistry showed that the glycosylated receptor was correctly inserted into the plasma membrane to a much larger extent than the non-glycosylated receptor, ...
