Role of the prostanoid EP4 receptor in iloprost-mediated vasodilatation in pulmonary hypertension.

RATIONALE Iloprost is effective for the treatment of pulmonary hypertension. It acts through elevation of cAMP by binding to the prostacyclin receptor (IP receptor). However, there is evidence that patients with severe pulmonary hypertension have decreased expression of the IP receptor in the remodeled pulmonary arterial smooth muscle. OBJECTIVES We hypothesized that prostanoid receptors othe...

Potent P2Y6 receptor mediated contractions in human cerebral arteries

BACKGROUND Extracellular nucleotides play an important role in the regulation of vascular tone and may be involved in cerebral vasospasm after subarachnoidal haemorrhage. This study was designed to characterise the contractile P2 receptors in endothelium-denuded human cerebral and omental arteries. The isometric tension of isolated vessel segments was recorded in vitro. P2 receptor mRNA express...

EP4-mediated prostanoid signalling promotes oral cancer progression

Cyclooxygenase-2 (COX-2) enzyme is upregulated in oral cancer (OSCC), where it catalyses PGE2 synthesis. We have shown previously that PGE2 promotes integrin-dependent OSCC invasion (1). PGE2 has four receptors (EP1-4), each coupled to different intracellular signaling pathways. We therefore investigated the role of EP receptor signaling in the invasive process. We used immunochemistry and RT-P...

The prostanoid EP4 receptor and its signaling pathway.

The EP4 prostanoid receptor is one of four receptor subtypes for prostaglandin E2. It belongs to the family of G protein-coupled receptors. It was originally identified, similar to the EP2 receptor as a G(s)α-coupled, adenylyl cyclase-stimulating receptor. EP4 signaling plays a variety of roles through cAMP effectors, i.e., protein kinase A and exchange protein activated by cAMP. However, emerg...

TRPV1 receptor-mediated expression of Toll-like receptors 2 and 4 following permanent middle cerebral artery occlusion in rats

Objective(s): Stroke is known as a main cause of mortality and prolonged disability in adults. Both transient receptor potential V1 (TRPV1) channels and toll-like receptors (TLRs) are involved in mediating the inflammatory responses. In the present study, the effects of TRPV1 receptor activation and blockade on stroke outcome and gene expression of TLR2 and TLR4 were assessed following permanen...
