GPI — PTGS2
Text-mined interactions from Literome
Tegeder et al., J Pharmacol Exp Ther 2000
:
Because PGF ( 1alpha ) is the stable breakdown product of PGI ( 2 ), these results suggest that
COX-2 contributes to
PGI ( 2 ) synthesis in the rat stomach
Smith et al., Arterioscler Thromb Vasc Biol 2002
:
However, selective inhibition of
COX-2 , but not COX-1,
blocked PGI2 production under low cholesterol conditions
Jaffar et al., J Immunol 2002
(Inflammation) :
Selective inhibition of
cyclooxygenase-2 in vivo specifically
reduced PGI ( 2 ) synthesis and resulted in a marked increase in Th2 mediated, but not Th1 mediated, lung inflammation
Pirkebner et al., J Cell Physiol 2004
(Colonic Neoplasms) :
Additionally, analysis utilizing protein synthesis inhibitor cycloheximide demonstrated that
pHi mediated inhibition of
COX-2 mRNA expression requires de novo protein synthesis of regulatory protein ( s )
Shinmura et al., Basic Res Cardiol 2004
(Myocardial Reperfusion Injury) :
A
COX-2 dependent increase in
PGI ( 2 ) production is essential for BW373U86 induced late PC in both sexes and in both young and old rats
Schildknecht et al., FASEB J 2004
:
Specific
COX-2 inhibitors completely
blocked PGI2 formation but PGE2 synthesis only partially
Norata et al., Int J Mol Med 2004
:
N-LDL and Ox-LDL increased PGE2 release in a
Cox-2 dependent manner while TXA2 and
PGI2 release were not affected either by n-LDL or Ox-LDL
Hui et al., Prostaglandins Leukot Essent Fatty Acids 2004
(Liver Neoplasms) :
COX-2 was
responsible for the production of PGE ( 2 ) and
PGI ( 2 ) in PDGF stimulated LI90 cells
Huang et al., Hum Reprod 2004
:
The
effects of
COX-2 inhibitor on
PGI2 production were ascertained ... The
PGI2 production was markedly
reduced by a selective
COX-2 inhibitor
Damirin et al., Mol Pharmacol 2005
:
In conclusion, S1P induced cAMP accumulation through S1P receptors, including S1P(2) receptor and G ( i/o ) protein mediated stimulation of intracellular signaling pathways involving
cyclooxygenase-2 dependent
PGI ( 2 ) synthesis
Smith et al., J Lipid Res 2005
:
We previously demonstrated that cholesterol deprivation increases endothelial
cyclooxygenase-2 (COX-2) dependent prostacyclin [
prostaglandin I2 (PGI2) ] production in vitro
Fauti et al., FEBS J 2006
:
In agreement with this conclusion, the overexpression of ectopic
Cox-2 and PGI2 synthase (PGIS)
resulted in massive
PGI2 synthesis but did not activate the transcriptional activity of PPARbeta
Pham et al., J Cell Biochem 2006
:
Recently, we showed in an ileal epithelial cell line ( IEC-18 ), angiotensin II-induced
COX-2 dependent
PGI2 production through p38MAPK, and calcium mobilization ( J. Biol. Chem. 280 : 1582-1593, 2005 )
Cook-Johnson et al., Biochim Biophys Acta 2006
:
PGI ( 2 ), but not TXA ( 2 ) synthesis, was absolutely
dependent on upregulation of
COX-2 by hypoxia
García Rodríguez et al., PLoS Med 2007
(Coronary Disease...) :
Furthermore, estrogen confers atheroprotection via
COX-2 dependent
PGI2 in mice, raising the possibility that COX inhibitors may undermine the cardioprotection, suggested by observational studies, of endogenous or exogenous estrogens
Tan et al., J Immunol 2007
:
Histamine induced increases in
PGI ( 2 ) and PGE ( 2 ) production were
due to increased expression and function of
COX-2 because gene silencing by small interfering RNA or inhibition of the catalytic activity by a COX-2 inhibitor blocked prostanoid production
Lee et al., J Immunol 2008
:
Furthermore, the up-regulation of PGE ( 2 ) and
PGI ( 2 ) production was markedly
down-regulated by indomethacin and a selective
COX-2 inhibitor
Martínez-González et al., J Nutr 2008
:
Therefore, oleanolic acid contributes to vascular homeostasis by inducing
PGI2 release in a
Cox-2 dependent manner
Araujo et al., American journal of physiology. Renal physiology 2010
(Hypertension) :
Acute infusion of the vasoconstrictor ANG II increases
COX-2 dependent PGE ( 2 ) and
PGI ( 2 )
Leyva et al., Lung 2010
:
PGI ( 2 ) release was
mediated by
cyclooxygenase-2 (COX-2) and vitronectin receptor (VNR)
Deacon et al., J Biol Chem 2010
(Vascular Diseases) :
Amphiregulin, follistatin, and inhibin-beta-A and epiregulin were activated by an autocrine loop involving cPLA2, arachidonic acid release,
COX-2 dependent
PGI ( 2 ) synthesis, and IP receptor linked elevation of cAMP leading to CRE transcription activation
Brenneis et al., J Biol Chem 2011
(Disease Models, Animal...) :
Interestingly, we found that activation of E-prostanoid ( EP ) 2 and EP4 receptors, but not EP1, EP3,
PGI(2) receptor ( IP ), thromboxane A(2) receptor ( TP ), PGD(2) receptor ( DP ), and PGF ( 2 ) receptor ( FP ), efficiently
blocked LPS induced tumor necrosis factor a (TNFa) synthesis and
COX-2 and mPGES-1 induction as well as prostaglandin synthesis in spinal cultures
Dovizio et al., J Pharmacol Exp Ther 2012
(Adenomatous Polyposis Coli) :
Thus, a profound inhibition of
COX-2 dependent
PGI ( 2 ) might be associated with changes in circulating markers of angiogenesis
Przygodzki et al., Eur J Pharmacol 2013
(Diabetes Mellitus) :
However,
COX-2 activity significantly
contributed to
PGI ( 2 ) synthesis in healthy rats, with prostacyclin secretion being two-fold decreased by NS-398
Sakata et al., Thromb Res 2013
(Carotid Artery Thrombosis...) :
Aspirin inhibits both the cyclooxygenase (COX)-1 dependent production of thromboxane A2 ( TXA2 ) in platelets and
COX-2 dependent production of anti-aggregatory
prostaglandin I2 (PGI2) in vessel walls, resulting in `` aspirin dilemma. ''
