T prostaglandin pathway proteins studied. Previous descriptions of prostaglandin pathway gene
T prostaglandin pathway proteins studied. Previous descriptions of prostaglandin pathway gene expression have focused largely on the cyclooxygenase/ prostaglandin H2 synthase genes PTGS1 and PTGS2 (formerly Cox1 and Cox2). Not all preceding observations could be reconciled with each other.Table 3 Immunolocalisation of PG pathway proteins in uterine cell populationsPLACENTA Basal plate Protein PTGS1 PTGS2 PTGES AKR1B1 AKR1C3 CBR1 SLCO2A1 HPGD +[16] +[16] + + + + +[24] + + + + + + + EVT DC ST [14] +[14,16] +[21,22] + + + + +[18,24] + + Chorionic Villi VF [15] +[15] VM +[15] [15,17] + VC [14] [14] [21,22] + + + + + + +[18] + +[21] +[21] + +[21] +[21] +[17,19] +[19,20] +[21-23] +[19] +[19] + +[19] +[18,19,24] + + + + + + + + + + +[19] +[19] +[17,19,20] +[21-23] + + Chorionic Plate EVT AE DC CT MEMBRANES Choriodecidua CF AF Amnion AE INF ILProtein immunolocalisation identified within this study is represented by shaded cells; earlier observations are referenced.

Scale bar = 50 m.Inside the placenta, there is certainly proof suggesting no modify in PTGS1 expression with gestational age [15], and contrasting proof of decreasing expression with escalating gestational age at labour [25]. In gestational membranes, increasing gestational age has been associated with increased [26,27], unchanged [27,28], and decreased [29] PTGS1 expression. Likewise, the incidence of labour has been associated with elevated [26,27] and unchanged [30-36] PTGS1 expression. Inside the placenta, the current evidence suggests that there is certainly no change in expression of PTGS2 with gestational age or clinical chorioamnionitis [25]. Within the gestational membranes, quite a few studies have shown greater PTGS2 expression with escalating gestational age [26-29]. There is certainly evidence supporting each improved PTGS2 expression following labour [26-28,31-35] and no alter with labour [20,36,37]. Data relating to intrauterine expression of other prostaglandin pathway genes is restricted. Our previous operate demonstrated expression of the 15 prostaglandin pathway genes in placenta, amnion and choriodecidua [13]. Also, PLA2G4A (phospholipase A2, group IVA (cytosolic, calcium-dependent)) expression has been identified in human placenta and gestational membranes.
