in this paper a general discussion of the available data on the role of prostaglandin (pg) and phosphodiesterase is discussed. functional studies would be a next step to understand the functional meaning of the data described in this paper. the data presented are a basis for further research on selective modulation of the ep1 and ep2 receptor which could be a therapeutic target in functional bl...
Four prostaglandin E2 receptor subtypes designated EP1, EP2, EP3, and EP4 have been shown to mediate a variety of effects of prostaglandin E2 (PGE2) on glomerular hemodynamics, tubular salt and water reabsorption, and on blood vessels in the human kidney. Despite the important role of renal PGE2, the localization of PGE2 receptor proteins in the human kidney is unknown. The present study used a...
Clinical use of prostaglandin synthase-inhibiting NSAIDs is associated with the development of hypertension; however, the cardiovascular effects of antagonists for individual prostaglandin receptors remain uncharacterized. The present studies were aimed at elucidating the role of prostaglandin E2 (PGE2) E-prostanoid receptor subtype 1 (EP1) in regulating blood pressure. Oral administration of t...
Prostaglandin E(2) (PGE(2)) is a key mediator of exaggerated pain sensation during inflammation. Drugs targeting the PGE(2) pathway by global inhibition of cyclooxygenases are well established in the treatment of inflammatory pain, but also cause significant unwanted effects. Enzymes downstream of the cyclooxygenases, or prostaglandin receptors are candidate targets possibly enabling therapeuti...
A functional cDNA clone encoding mouse EP2 subtype of prostaglandin (PG) E receptor was isolated from a mouse cDNA library by cross-hybridization with the mouse EP3 subtype PGE receptor cDNA. The mouse EP2 receptor consists of 513 amino acid residues with putative seven-transmembrane domains. In contrast to EP3 receptor, this receptor possesses long third intracellular loop and carboxyl-termina...
Prostaglandin E2 (PGE2) mediates the stimulatory effect of norepinephrine (NE) on the secretion of luteinizing hormone-releasing hormone (LHRH), the neuropeptide controlling reproductive function. In rodents, this facilitatory effect requires previous exposure to estradiol, suggesting that the steroid affects downstream components in the cascade that leads to PGE2-induced LHRH release. Because ...
The studies of Ungrin et al. (2001) describe the ligand binding and activation of the human prostaglandin (PG) receptor assayed with an extensive panel of ligands. PGs are a diverse family of autocoids whose synthesis is initiated by cyclooxygenase-mediated metabolism of the unsaturated 20carbon fatty acid arachidonic acid to PGG/H2, generating five primary bioactive prostanoids: PGE2, PGD2, PG...
Recently, certain studies have demonstrated in vitro that prostaglandin E2 (PGE2) promotes human cluster of differentiation (CD)34+ cell homing. However, the sub‑type receptors activated by PGE2 are unknown, as the PGE2 receptor EP1-4 subtypes (EP1-4) are expressed on the membrane of human CD34+ cells. Based on the above, the present study aimed to screen the receptor subtype activity by PGE2 t...
