Cyclooxygenase-2 prostaglandins mediate anandamide-inhibitory action on nitric oxide synthase activity in the receptive rat uterus
(Elsevier Science, 2012-06)
Anandamide, an endocannabinoid, prostaglandins derived from cyclooxygenase-2 and nitric oxide synthesized by nitric oxide synthase (NOS), are relevant mediators of embryo implantation. We adopted a pharmacological approach ...
Inhibition of cyclooxygenase activity by standardized hydroalcoholic extracts of four Asteraceae species from the Argentine Puna
(Associação Brasileira de Divulgação Científica, 2009-09)
We determined the anti-inflammatory activity of standardized extracts of four medicinal plant species (Baccharis incarum, B. boliviensis, Chuquiraga atacamensis, Parastrephia lucida) that grow in the Argentine Puna (3800 ...

Prolactin (PRL) induction of cyclooxygenase 2 (COX2) expression and prostaglandin (PG) production in hamster Leydig cells
(Elsevier Ireland, 2012-01)
Serum prolactin (PRL) variations play a crucial role in the photoperiodic-induced testicular regression–recrudescence transition in hamsters. We have previously shown that cyclooxygenase 2 (COX2), a key enzyme in the ...
17-Octadecynoic acid improves contractile response to angiotensin II by releasing vasocontrictor prostaglandins
(Elsevier Science Inc, 2012-01)
The present study investigated the role of CYP-enzymes in the modulation of vasoconstrictor responses to angiotensin II in rabbit aortae. In arteries with the endothelium-intact (E+) the CYP-inhibitor, 17-octadecynoic acid ...
Cholinoceptor Modulation on Nitric Oxide Regulates Prostaglandin E2 and Metalloproteinase-3 Production in Experimentally Induced Inflammation of Rat Dental Pulp
(Elsevier Science Inc, 2009-04)
The purpose of this study was to investigate the role of muscarinic acetylcholine receptor (mAChR) activity in the regulation of inducible nitric oxide synthase (iNOS) activity, prostaglandin E2 (PGE2), and metalloproteinase-3 ...
Dietary n-9, n-6 and n-3 fatty acids modulate the oxidative stress in brain and liver of mice: Effect of trans fatty acids supplementation
(IOS Press, 2021-03)
BACKGROUND: Arachidonic (20:4n-6) and docosahexaenoic (22:6n-3) acids interaction affects brain structure and function. Unsaturated fatty acids (UFAs) generate oxygenated lipid-derived eicosanoids which modulate the ...
Reduced nitric oxide synthase and cyclo-oxygenase activity in the uterus of non-obese diabetic mice
(BioScientifica, 2006-12)
A functional interaction between progesterone, Th2 cytokines and a suitable balance between nitric oxide and prostaglandins in the uterus is considered to have a major role in the success of embryo implantation and pregnancy. ...
Exposure to growth hormone is associated with hepatic up-regulation of cPLA2α and COX
(Elsevier Ireland, 2020-06)
Continuously elevated levels of growth hormone (GH) during life in mice are associated with hepatomegaly due to hepatocytes hypertrophy and hyperplasia, chronic liver inflammation, elevated levels of arachidonic acid (AA) ...
Cyclooxygenase-2 in testes of infertile men: Evidence for the induction of prostaglandin synthesis by interleukin-1β
(Elsevier Science Inc, 2010-10)
As we previously reported, testes of men suffering from hypospermatogenesis and germ cell arrest or Sertoli cell-only syndrome show a major increase in the number of macrophages expressing interleukin-1β (IL-1β) and abundant ...
