EP2 Receptor Activates Dual G Protein Signaling Pathways that Mediate Contrasting Proinflammatory and Relaxatory Responses in Term Pregnant Human Myometrium.
Abstract Prostaglandin (PG) E2 (PGE2) plays a central role in the regulation of smooth muscle contractions. Classically, PGE2 stimulates contractions via EP1 and EP3 receptors, whereas EP2 and EP4 maintain quiescence. Labor involves a change from myometrial quiescence to contractions with a shift from anti- to proinflammatory pathways. EP2, a Gαs-coupled receptor, is known to mediate its actions via cAMP signaling. However, we have recently shown that EP2 also activates the proinflammatory PG G/H synthase-2 (PGHS-2). Here, we identify the mechanism underlying the ability of EP2 to maintain uterine quiescence and ...
