Identification and localization of prostaglandin E2 receptors in upper and lower segment human myometrium during pregnancy.
Prostaglandin E2 (PGE2) plays a key role in the maintenance of human pregnancy and labour onset. PGE2 can elicit diverse actions within the uterus depending on the PGE2 receptors (EP1, EP2, EP3 and EP4) expressed. By signalling through different intracellular pathways the EP receptors may inhibit or promote smooth muscle contractility. Nine different EP3 receptor splice variants have been ident...
متن کاملExpression of the calcium-activated potassium channel in upper and lower segment human myometrium during pregnancy and parturition
BACKGROUND Large conductance calcium-activated potassium channel (BKCa) plays an important role in the control of uterine contractility during pregnancy. The change from uterine quiescence to enhanced contractile activity may be associated with the spatial and temporal expression of BKCa within myometrium. The objectives of this study were to examine the expression of BKCa alpha- and beta-subun...
متن کاملExpression of prothrombin and protease activated receptors in human myometrium during pregnancy and labor.
As thrombin is proposed to be involved in stimulating myometrial contractility during labor and preterm labor, we aimed to investigate the expression of prothrombin (F7), the precursor of thrombin, its receptors, the protease-activated receptor (PAR) family (F2R, F2RL1, F2RL2, and F2RL3), and prothrombinase FGL2 in human myometrium during pregnancy and labor. Messenger RNA and protein were isol...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Reduced expression of CRH receptor type 1 in upper segment human myometrium during labour
BACKGROUND Corticotropin-releasing hormone (CRH) and CRH-related peptide are shown to modulate uterine contractility through two CRH receptor subtype, CRH-R1 and CRH-R2 during pregnancy. Through different signaling pathways, CRH-R1 maintains myometrial quiescence whereas CRH-R2 promotes smooth muscle contractility. We hypothesized that the expression of CRH receptors in myometrium might be chan...
