Abstract:
Liver can function as part of the innate and adaptive immune systems. We hypothesize that prostaglandins participate in the regulation of hepatic immune function during early pregnancy in sheep. The objective of this study was to elucidate expression of prostaglandin synthase in ovine liver during early pregnancy. Ovine livers were sampled on day 16 of the estrous cycle, and days 13, 16, and 25 of pregnancy, and the expression of prostaglandin synthases, including prostaglandin-endoperoxide synthase 1 (PTGS1), PTGS2, prostaglandin E synthase (PTGES), and aldo-keto reductase family 1, member B1, a prostaglandin F synthase (PGFS), were detected by quantitative real-time polymerase chain reaction, Western blot, and immunohistochemistry analysis. There were increases in the expression of mRNA and the proteins of PTGS2, PTGES, and PGFS in the livers during early pregnancy, but PTGS1 was decreased in the pregnant ewes. The PGFS protein was limited to the hepatocytes and the endothelial cells of the proper hepatic arteries and hepatic portal veins. In summary, the upregulation of PTGS2, PTGES, and PGFS and downregulation of PTGS1 may be involved in the maternal hepatic immune adjustment during early pregnancy in sheep.

Abstract:
Prostaglandin (PG) E2and PGI2are essential to hyperalgesia in inflammatory tissues. These prostaglandins are produced from arachidonic acid, which is cleaved from membrane phospholipids by the action of phospholipase A2(PLA2). Which isozyme of PLA2is responsible for the cleavage of arachidonic acid and the production of prostaglandins essential to inflammation-induced hyperalgesia is not clear. In this study, we examined the effects of two PLA2isozyme-specific inhibitors on carrageenan-induced production of PGE2and PGI2in rat hind paw and behavioral nociceptive response to radiant heat. Local administration of bromoenol lactone (BEL), an inhibitor of calcium-independent PLA2(iPLA2), significantly reduced carrageenan-induced elevation of prostaglandins in the inflamed foot pad 3 h after injection. It also ameliorated the hyperalgesic response between 1 h and 3 h after carrageenan injection. On the other hand, AACOCF3, an inhibitor of cytosolic PLA2, suppressed neither prostaglandin production nor the hyperalgesic response. BEL did not suppress the mRNA levels of iPLA2β, iPLA2γ, cyclooxygenase-2, microsomal prostaglandin E synthase, prostaglandin I synthase, or proinflammatory cytokines in the inflamed foot pad, indicating that BEL did not suppress inflammation itself. These results suggest that iPLA2is involved in the production of prostaglandins and hyperalgesia at the inflammatory loci.

Full text
Abstract:
Prostaglandin E2 (PGE2) and prostaglandin F2 alpha (PGF2 alpha) inactivated glycogen synthase and activated glycogen phosphorylase in rat hepatocytes in a dose- and time-dependent manner. These effects were dependent on the presence of Ca2+ in the incubation medium. When glycogen synthase was immunoprecipitated from cells incubated with [32P]Pi and then treated with PGE2 or PGF2 alpha, there was increased phosphorylation of the 88 kDa subunit of the enzyme. This phosphorylation affected two CNBr fragments of the glycogen synthase, CB-1 and CB-2, the same fragments that are phosphorylated by different glycogenolytic hormones. No phosphorylation of glycogen synthase by prostaglandins was observed in the absence of Ca2+. Thus the effect of PGE2 and PGF2 alpha on these glycogen-metabolizing enzymes supports a role for regulation by prostaglandins of glucose metabolism in parenchymal liver cells.

Abstract:
ABSTRACT Cryptosporidium parvum is an important cause of diarrhea in humans and several animal species. Prostaglandins play a central role in regulating intestinal fluid secretion in animal models of cryptosporidiosis, but their cellular sources and mechanisms of induction are unclear. Here, we show that C. parvuminfection directly activates prostaglandin H synthase 2 expression and prostaglandin E2 and F2α production in human intestinal epithelial cells.

Full text
Abstract:
It seems likely that prostaglandins play a significant part in the mechanisms of parturition both at term and preterm. Concentrations of prostaglandins are increased in the blood, urine and amniotic fluid during labour. There are differences in the concentrations of prostaglandins in amniotic fluid from the forebag and hindbag. Nevertheless, if liquor is sampled only from the hindbag a highly significant increase in prostaglandin concentrations occurs throughout labour. Furthermore, we now have evidence that prostaglandin concentrations in amniotic fluid increase before the onset of labour. Prostaglandins are synthesized by uterine tissues and increased rates of production occur during labour. The amnion, chorion and decidua all contain mRNA for the newly-discovered inducible form of prostaglandin H synthase (PGHS-2) as well as mRNA for the constitutive form (PGHS-1). Using the reverse transcription polymerase chain reaction (RT-PCR) both mRNAs can be detected during late pregnancy whether women are in labour or not. PGHS-2 protein is detected by Western blot analysis in cells derived from all three tissues. There is regulation of PGHS-2 protein amounts by cytokines, phorbol esters and growth factors. For example, in amnion cells interleukin-1 beta induces a rapid increase in PGHS-2 mRNA levels followed by a decrease to undetectable levels within 4 h of treatment; PGHS-2 protein amounts are also elevated by this treatment. Administration of prostaglandins will induce labour and delivery, whereas inhibition of prostaglandin biosynthesis will delay labour and delivery. Hence, increased prostaglandin production is likely to be a key determinant of the onset and progression of the parturient process.

Abstract:
The present study was designed to assess whether or not changes in genomic expression of cyclooxygenases (COX-1, COX-2), endothelial nitric oxide synthase (eNOS), and prostanoid synthases in the endothelium and of prostanoid receptors in vascular smooth muscle contribute to the occurrence of endothelium-dependent contractions during aging and hypertension. Gene expression was quantified by real-time PCR using isolated endothelial cells and smooth muscle cells (SMC) from the aorta of Wistar-Kyoto and spontaneously hypertensive rats. Genes for all known prostanoid synthases and receptors were present in endothelial cells and SMC, respectively. Aging caused overexpression of eNOS, COX-1, COX-2, thromboxane synthase, hematopoietic-type prostaglandin D synthase, membrane prostaglandin E synthase-2, and prostaglandin F synthase in endothelial cells and COX-1 and prostaglandin E2 (EP)4 receptors in SMC. Hypertension augmented the expression of COX-1, prostacyclin synthase, thromboxane synthase, and hematopoietic-type prostaglandin D synthase in endothelial cells and prostaglandin D2 (DP), EP3, and EP4 receptors in SMC. The increase in genomic expression of endothelial COX-1 explains why in aging and hypertension the endothelium has greater propensity to release cyclooxygenase-derived vasoconstrictive prostanoids. The expression of prostacyclin synthase was by far the most abundant, explaining why the majority of the COX-1-derived endoperoxides are transformed into prostacyclin, substantiating the role of prostacyclin as an endothelium-derived contracting factor. The expression of thromboxane synthase was increased in the cells of aging or hypertensive rats, explaining why the prostanoid can contribute to endothelium-dependent contractions. It is uncertain whether the gene modifications caused by aging and hypertension directly contribute to endothelium-dependent contractions or rather to vascular aging and the vascular complications of the hypertensive process.

Abstract:
Inositol-requiring enzyme 1[α] (IRE1[α])–X-box binding protein spliced (XBP1) signaling maintains endoplasmic reticulum (ER) homeostasis while controlling immunometabolic processes. Yet, the physiological consequences of IRE1α–XBP1 activation in leukocytes remain unexplored. We found that induction of prostaglandin-endoperoxide synthase 2 (Ptgs2/Cox-2) and prostaglandin E synthase (Ptges/mPGES-1) was compromised in IRE1α-deficient myeloid cells undergoing ER stress or stimulated through pattern recognition receptors. Inducible biosynthesis of prostaglandins, including the pro-algesic mediator prostaglandin E2 (PGE2), was decreased in myeloid cells that lack IRE1α or XBP1 but not other ER stress sensors. Functional XBP1 transactivated the human PTGS2 and PTGES genes to enable optimal PGE2 production. Mice that lack IRE1α–XBP1 in leukocytes, or that were treated with IRE1α inhibitors, demonstrated reduced pain behaviors in PGE2-dependent models of pain. Thus, IRE1α–XBP1 is a mediator of prostaglandin biosynthesis and a potential target to control pain.

Full text
Abstract:
ABSTRACT The capacity of cotyledonary microsomes, prepared from pregnant ewes (20–145 days of gestation), to metabolize exogenous arachidonic acid was quantified using a radiolabel technique. During gestation, the capacity of microsomes to metabolize arachidonic acid increased 25-fold, from 0·36±0·06μmol arachidonic acid/incubation (n = 8) at <100 days of gestation to 9·06±1 ·02μmol arachidonic acid/incubation at 130–145 days of gestation (n = 5; P<0·05). Arachidonic acid was metabolized to prostaglandin E2 and F2α, as determined by thin-layer chromatography and reverse-phase high performance liquid chromatography. The profile of prostaglandins synthesized by cotyledonary microsomes did not change throughout gestation. These data suggest that the increase in cotyledonary prostaglandin synthesis that occurs during late gestation and at term may reflect an increase in the tissue content of prostaglandin H2 synthase.

Abstract:
Organ fibrosis is a common pathological result of various chronic diseases with multiple causes. Fibrosis is characterized by the excessive deposition of extracellular matrix and eventually leads to the destruction of the tissue structure and impaired organ function. Prostaglandins are produced by arachidonic acid through cyclooxygenases and various prostaglandin-specific synthases. Prostaglandins bind to homologous receptors on adjacent tissue cells in an autocrine or paracrine manner and participate in the regulation of a series of physiological or pathological processes, including fibrosis. This review summarizes the properties, synthesis, and degradation of various prostaglandins, as well as the roles of these prostaglandins and their receptors in fibrosis in multiple models to reveal the clinical significance of prostaglandins and their receptors in the treatment of fibrosis.

Abstract:
Les isoprostanes (isops), isomeres des prostaglandines, sont une nouvelle classe de produits naturels decouvertes dans les annees 1990. Les isops sont naturellement formees, lors de l'attaque oxydante de l'acide arachidonique (aa), par reaction de cyclisation radicalaire intramoleculaire avec introduction de trois atomes d'oxygene. La 15-f#2#t-isop, la plus abondante, possede de puissantes activites biologiques et est actuellement consideree comme un bon marqueur de la peroxydation lipidique. A cause de l'interet porte a ce compose, nous en avons developpe la synthese totale. La strategie retenue est une strategie biomimetique. En effet, l'etape cle de cette synthese utilise le mecanisme suppose de la formation in vivo des isops au moyen d'une cyclisation radicalaire de type 1,5,7-octadienyle d'un motif a 20 atomes de carbone mimant l'aa. La synthese biomimetique de la 15-f#2#t-isop a permis de confirmer la biosynthese des isops et sa formation possible a partir de l'aa esterifie. Nous avons aussi aborde la synthese de l'enantiomere d'un des metabolites urinaires de la 15-f#2#t-isop, l'ent-15(rs)-5,6-dihydro-2,3-dinor-15-f#2#t-isop. L'approche retrosynthetique est basee sur la formation d'un cycle pentanique polysubstitue de configuration adequate sur lequel sont fixes les chaines laterales du metabolite. L'obtention de ces deux molecules, en particulier la 15-f#2#t-isop, pouvant etre marquee au deuterium ou au tritium, presente un interet majeur pour des etudes biologiques. D'autre part, ces deux isops peuvent etre un index de peroxydation lipidique representatif des attaques oxydantes in vivo.

While aspirin (ASA) inhibits platelet function for several days, it returns to normal within 24 hours after indobufen (IDB), a reversible cyclooxygenase inhibitor, suggesting that prostacyclin may recover at an even faster rate. In a randomised, controlled study, recovery of platelet and endothelial cell prostaglandin synthesis was compared in 49 New Zealand white rabbits following indobufen (3.5 mg/kg) or aspirin (5 mg/kg). Prostacyclin in arterial incubates and platelet thromboxane A2 (TXA2) production in serum were measured by radioimmunoassay of their meta-bolities, 6Keto PGF1 and thromboxane B2. Platelet prostaglandin synthesis was also monitored by changes in serum malondiealdehyde (MDA).At one hour, both ASA and IDB significantly inhibited PGI2 (p<0.005). TXA2 (p<0.005), and MDA (p<0.02). After IDB, TXA2 and MDA levels returned to normal by 24 hours while inhibition continued in the ASA group (p<0.01). PGI2 synthesis following IDB recovered at 8 hours against 24 hours in the ASA group. We conclude that while both drugs inhibit platelet and endothelial prostaglandins, the earlier recovery of prostacyclin synthesis following indobufen may allow the endothelium to resume its physiological function.
