Wang et al., Zhonghua Jie He He Hu Xi Za Zhi 1999
(Respiratory Distress Syndrome, Adult) :
Selective
COX-2 inhibitor Meloxicam alleviated histopathologic damage in the lung,
inhibited production of
PGs and attenuated PaO2 decline
FitzGerald et al., Am J Cardiol 2002
(Arthritis...) :
However, later research has demonstrated a
role of
COX-2 in production of
PGs that have functions under normal physiologic conditions
Yokota et al., J Clin Invest 2002
:
They also link adiponectin to the
COX-2 dependent
PGs that are critical in this process
Okada et al., J UOEH 2003
(Bone Resorption) :
Stimulated production of
PGs by osteoblasts
requires both the induction of
COX-2 expression and the availability of arachidonic acid substrate
Kuo et al., Cancer Lett 2004
(Mouth Neoplasms) :
Because
cyclooxygenase-2 (COX-2) plays a key role in
prostaglandins (PGs) synthesis, which is elevated in inflammation, we examined whether the anti-inflammatory mechanism of berberine is mediated through COX-2 regulation
Brune et al., Rheumatology (Oxford) 2004
(Disease Progression...) :
Cyclooxygenase (COX)-1 and
COX-2 are
responsible for the production of
PGs
Hinz et al., FASEB J 2005
(MAP Kinase Signaling System) :
A contribution of
cyclooxygenase-2 (COX-2) dependent
PGs to this process was emphasized by a recent study showing an impaired COX-2 expression in the nonpigmented ciliary epithelium ( NPE ) of patients with primary open-angle glaucoma
Rösch et al., J Pharmacol Exp Ther 2006
:
Our results further imply an involvement of
COX-2 dependent
PGs in MMP-9 and TIMP-1 expression
Neild et al., J Immunol 2005
(Legionellosis) :
Cyclooxygenase-2 dependent production of
PGs by IFN-gamma treated BMphi infected with Legionella was required for inhibition of effector T cell responses
Ho et al., J Clin Periodontol 2008
(Chronic Disease...) :
COX-2 , which is induced in an inflammatory response, is
responsible for
PGs synthesis at sites of inflammation
Mayoral et al., Biochem J 2008
:
These results show, in a genetic model, that tissue-specific
COX-2 dependent
PGs exert an efficient protection against acute liver injury by an antiapoptotic/antinecrotic effect and by accelerated early hepatocyte proliferation
Twarock et al., Br J Pharmacol 2009
(Carcinoma, Squamous Cell...) :
Furthermore,
COX2 dependent synthesis of
prostaglandins (PGs) stimulates HA synthase-1 (HAS1) and HAS2 mRNA expression, together with HA synthesis via the cAMP/protein kinase A pathway in vascular smooth muscle cells
Cella et al., Br J Pharmacol 2010
(Disease Models, Animal...) :
Co-administration of meloxicam, a
cyclooxygenase-2 inhibitor, or aminoguanidine, an inducible NOS inhibitor, prevented LPS induced preterm delivery and
blocked the increase in
PGs and NO
Llorente Izquierdo et al., Am J Pathol 2011
(Body Weight...) :
The effect of
COX-2 dependent
PGs in chronic liver disease, hepatitis, fibrosis, and chemical hepatocarcinogenesis, has been investigated in transgenic ( Tg ) mice that express human COX-2 in hepatocytes and in Tg hepatic human cell lines ... The contribution of
COX-2 dependent
PGs to the development of DEN induced hepatocarcinogenesis was evaluated in Tg mice, Tg hepatocyte-like cells, and nude mice and the analysis revealed that COX-2 expression favors the development of preneoplastic foci without affecting malignant transformation
Ramer et al., Mol Cancer Ther 2013
(Lung Neoplasms) :
Together, our data show a novel proapoptotic mechanism of cannabidiol involving initial upregulation of COX-2 and PPAR-? and a subsequent nuclear translocation of PPAR-? by
COX-2 dependent
PGs
Xu et al., Endocrinology 2013
:
Collectively, these data indicate that
NF?B/COX-2 induced
PGs regulate leukocyte influx, leading to endometrial breakdown
Charpigny et al., Endocrinology 1997
:
Collectively these results suggest that the developing ability of the uterus to synthesize
PGs is
due to the induction of
cox-2
Kusuhara et al., Brain Res Mol Brain Res 1997
:
Time-course studies on the mRNA expression for c-fos in the hind brain and cyclooxygenase (COX) isoforms in the peritoneal cells, as well as on the peritoneal 6-keto-PGF1alpha accumulation, after stimulation indicated that COX-1 but not
COX-2 was
responsible for the peritoneal synthesis of
PGs which were suggested to evoke c-fos expression in the hind brain
Terao et al., Neuroreport 1998
:
These results indicate that
COX-2 mediated hyperproduction of
PGs is critically involved in the enhancement of SWS, fever, and anorexia but not in the suppression of PS, caused by TNFalpha infused into the PGD2-sensitive zone
