Prostaglandin E2 (PGE2) is expressed in articular joints with inflammatory arthropathy and may exert catabolic effects leading to cartilage degradation. As we observed in a preliminary experiment that PGE2 suppressed the expression of SERPINE1/plasminogen activator inhibitor (PAI)-1 mRNA in chondrocytes, we focused on the effect of PGE2 on PAI-1 in a panel of cultured chondrocytes obtained from...
Substance P (SP) and ATP evoke transient, epithelium-dependent relaxation of constricted mouse tracheal smooth muscle. Relaxation to either SP or ATP is blocked by indomethacin, but the specific eicosanoid(s) involved have not been definitively identified. SP and ATP are reported to release PGE2 from airway epithelium in other species, suggesting PGE2 as a likely mediator in epithelium-dependen...
The epithelial cell line I407 up-regulates cyclooxygenase-2 (COX-2) mRNA and protein expression following ionizing radiation exposure. Prostaglandin E2 (PGE2) production is concomitantly up-regulated. Irradiation of I407 cells also results in phosphorylation of the p38 mitogen-activated protein kinase and the p38 inhibitor SB203580 abrogates radiation-induced PGE2 synthesis. Wild-type p38alpha ...
Objectives: to compare the mechanical, pharmacological or combination of both in induction labour. Methods: This comparative observational study was conducted Department Obs and Gynae, Lady Reading Hospital, from January 2019 December 2019. In this all women presenting labor room with singleton pregnancy gestational age > 37 weeks admitted for were included. All those multiple pregnancies, p...
The dermis is mainly constructed by type I collagen fibers, which provide mechanical strength to the skin building a frame-like structure, and elastic elasticity respond movements of skin. depletion fibers disappearance oxytalan are fiber, characteristic changes in photoaged Prostaglandin E2 (PGE2) one chemical mediators involved inflammation responsible for sunburn. Furthermore, it has been re...
The aim of this study was to determine which PGE2 receptors and signal transduction pathways are responsible for the stimulation of oxygen uptake in liver. Hepatic parenchymal cells isolated from female Sprague-Dawley rats were incubated either with PGE2, 17-phenyl-omega-trinor PGE2 (an EP1-specific agonist), or 11-deoxy PGE1 (an EP2/EP4-specific agonist), and oxygen consumption was measured. B...
In human aortic smooth muscle cells, prostaglandin E2 (PGE2) stimulates adenylyl cyclase (AC) and attenuates the increase in intracellular free Ca concentration evoked by activation of histamine H1 receptors. The mechanisms are not resolved. We show that cAMP mediates inhibition of histamine-evoked Ca signals by PGE2. Exchange proteins activated by cAMP were not required, but the effects were a...
The control of dendritic cell (DC) migration is pivotal for the initiation of cellular immune responses. In this study, we demonstrate that the migration of human monocyte-derived (Mo)DCs as well as of ex vivo peripheral blood DCs toward CCL21, CXCL12, and C5a is stringently dependent on the presence of the proinflammatory mediator PGE2, although DCs expressed CXCR4 and C5aR on their surface an...
Resveratrol is a natural polyphenol found in red grape skins, berries and red wine. Accumulating evidence suggests that resveratrol has various beneficial effects on the human body. In the present study, we investigated the effects of prostaglandin E2 (PGE2) on osteoprotegerin (OPG) synthesis and the effects of resveratrol on OPG synthesis in osteoblastlike MC3T3-E1 cells. PGE2 significantly st...
Prostaglandin E2 induces FOXP3 gene expression and T regulatory cell function in human CD4+ T cells.
Naturally occurring CD4+CD25+ regulatory T cells (T reg) are pivotal in suppressing immune responses and maintaining tolerance. The identification of molecules controlling T reg differentiation and function is important in understanding host immune responses in malignancy and autoimmunity. In this study we show that PGE2 enhances the in vitro inhibitory function of human purified CD4+CD25+ T re...
