Differential Placental Gene Expression in Severe Preeclampsia

We investigated the global placental gene expression profile in severe preeclampsia. Twenty-one women were randomly selected from 50 participants with uncomplicated pregnancies to match 21 patients with severe preeclampsia. A 30 K Human Genome Survey Microarray v.2.0 (Applied Biosystems) was used to evaluate the gene expression profile. After RNA isolation, five preeclamptic placentas were excluded due to poor RNA quality. The series composed of 37 hybridizations in a one-channel detection system of chemiluminescence emitted by the microarrays. An empirical Bayes analysis was applied to find differentially expressed genes. In preeclamptic placentas 213 genes were significantly (fold-change ≥ 2 and p ≤ 0.01) up-regulated and 82 were down-regulated, compared with normal placentas. Leptin (40 fold), laeverin (10 fold), different isoforms of β-hCG (3–6 fold), endoglin (4 fold), FLT1 (3 fold) and FLT4 (2 fold) were up-regulated. PDGFD was down-regulated (2 fold). Several differentially expressed genes were associated with Alzheimer disease, angiogenesis, Notch-, TGFβ- and VEGF-signalling pathways. Sixteen genes best discriminated preeclamptic from normal placentas. Comparison between early- (<34 weeks) and late-onset preeclampsia showed 168 differentially expressed genes with oxidative stress, inflammation, and endothelin signalling pathways mainly involved in early-onset disease. Validation of the microarray results was performed by RT-PCR, quantitative urine hCG measurement and placental histopathologic examination. In summary, placental gene expression is altered in preeclampsia and we provide a comprehensive list of the differentially expressed genes. Placental gene expression is different between early- and late-onset preeclampsia, suggesting differences in pathophysiology.

Placental Dysferlin Expression is Reduced in Severe Preeclampsia

Dysferlin (DYSF) and myoferlin (MYOF), members of the ferlin family of membrane proteins, are co-expressed in human placental syncytiotrophoblast (STB). Although the role of these ferlin proteins in the placenta has yet to be established, it has been suggested that DYSF and MYOF may contribute to the stability of the apical STB plasma membrane. The release of STB-derived cellular debris increases in the setting of preeclampsia (PE), suggesting relative destabilization of the hemochorial interface. To test whether PE was associated with alterations in placental expression of DYSF and/or MYOF, a cross-sectional study was performed using specimens of villous placenta collected form women with severe PE (n = 10) and normotensive controls (n = 10). DYSF and MYOF expression were examined using quantitative real–time RT-PCR, immunoblotting, and immunofluorescence labeling of tissue specimens. Placental DYSF expression was 57% lower at the mRNA level (p = 0.03) and 38% lower at the protein level (p = 0.026) in severe PE as compared to normotensive subjects. There were no differences in placental MYOF protein or mRNA expression between these groups. No appreciable changes in the distribution of DYSF or MYOF within placental villi was observed in PE relative to control specimens. We conclude that DYSF expression is reduced in severe PE relative to gestational age-matched controls. As DYSF has a role in membrane repair, these data suggest a role for DYSF in the stability of the apical STB plasma membrane and may account, at least in part, for the increased shedding of microparticles from this membrane in PE.     

Maternal Serum Human Placental Growth Hormone (hPGH) at 11 to 13 Weeks of Gestation in Preeclampsia

Objective. Human placental growth hormone (hPGH) is produced by human placenta and plays a central role in the maternal metabolic adjustments to pregnancy. The objective of this study was to investigate the maternal serum concentration of hPGH at 11–13 weeks of gestation in pregnancies that subsequently developed preeclampsia (PE), and to examine the possible association with uterine artery pulsatility index (PI) and maternal serum pregnancy-associated plasma protein-A (PAPP-A). Methods. The maternal serum concentration of hPGH at 11–13 weeks was measured in a case–control study from 60 cases that developed PE and 120 unaffected controls. The measured hPGH concentration was converted into a multiple of the expected median (MoM) in unaffected pregnancies. Regression analysis was used to determine the significance of association between hPGH MoM with uterine artery PI MoM and PAPP-A MoM. Results. In the pregnancies that subsequently developed PE the median serum hPGH concentration was not significantly different from that in the unaffected group (0.92 versus 1.00 MoM), whereas uterine artery PI was increased (1.31 versus 1.01 MoM) and serum PAPP-A was decreased (0.76 versus 1.01 MoM). In the group that developed PE there was no significant association between serum hPGH MoM and gestational age at delivery, uterine artery PI MoM, or serum PAPP-A MoM. Conclusion. The finding that in the PE group serum hPGH level during the first trimester is normal suggests that it is unlikely that this hormone plays a role in the pathogenesis of PE.     

Increased Maternal Serum and Cord Blood Fibronectin Concentrations in Preeclampsia are Associated with Higher Placental Hyaluronic Acid and Hydroxyproline Content

Background. Total or cellular fibronectin (FN) determinations have been used to differentiate between normal and preeclamptic pregnants. The purpose of this study was to examine the relationship between maternal serum FN levels and the extracellular matrix molecule contents of placental tissue, such as FN, hyaluronic acid (HA) and hydroxyproline (HP) levels. Material and Methods. We obtained maternal blood samples and placental tissue samples from healthy (n = 17, controls) and preeclamptic pregnants (n = 29). We also obtained cord blood samples for FN and HA determination from the same patients. FN and HA concentrations in the placenta and maternal and cord blood were measured by and enzyme-linked immunosorbent assay and HP contents in the placenta were measured by a colorimetric assay. Results. FN levels in maternal serum, cord blood, and placenta were significantly higher in preeclamptics than in controls (p<0.001, p<0.001 and p<0.05, respectively). HA concentrations in the cord blood and placenta were found to be elevated in preeclamptics (p<0.05 and p<0.01). Preeclamptics had significantly higher placental HP levels than controls (p<0.001). Similar statistically significant results were obtained when the pregnant subjects classified as nulliparous and multiparous. There was no difference in ECM molecule levels between nulliporous and multiparous women in preeclamptic pregnant group. In regression analysis maternal serum FN levels were correlated with placental HA and HP levels (p<0.01 and p<0.01). There was a positive correlation between cord blood FN and both placental HP (p<001) and HA levels (p<0.01). FN levels in maternal serum, cord blood, and placenta were also negative correlated with fetal birth weight (p<0.01, p<0.05 and p<0.05, respectively). Conclusion. FN in maternal serum, cord blood, and placenta is increased with elevated placental HA and HP levels, probably reflecting placental basement membrane alterations during preeclampsia.     

Comparison of Serum Levels and the Placental Expression of Resistin Between Patients with Preeclampsia and Normal Pregnant Women

Objective. The aim of this study was to evaluate serum resistin levels in women with preeclampsia compared to those in normal pregnant women and normal non-pregnant women, and to examine placental resistin expression. Methods. Serum resistin levels were measured by enzyme-linked immunosorbent assay and placental resistin expression was determined by immunohistochemistry. Results. Serum resistin levels were significantly elevated in women with preeclampsia compared to normal pregnant women and non-pregnant women. There was no significant difference in placental resistin expression. Conclusion. The placenta may not be the origin of the resistin that contributes to increased serum levels in women with preeclampsia.
