Preeclampsia (PE), a perilous pregnancy complication with life-threatening potential, exhibits a hallmark of maternal endothelial dysfunction caused by compromised components within the placenta. Placenta-derived exosomes in the maternal bloodstream are observed to correlate with the likelihood of pre-eclampsia, but the precise manner in which these exosomes contribute to the disease process still needs to be established. click here Our hypothesis suggests that placental exosomes are the critical link between placental abnormalities and maternal endothelial dysfunction in preeclampsia.
From the plasma of preeclamptic patients and normal pregnancies, circulating exosomes were collected. The transendothelial electrical resistance (TEER) and FITC-dextran permeability assays were used to evaluate endothelial barrier function in human umbilical vein endothelial cells (HUVECs). To examine miR-125b and VE-cadherin expression in exosomes and endothelial cells, qPCR and Western blot techniques were used. The potential for miR-125b to post-transcriptionally regulate VE-cadherin expression was investigated through a luciferase assay.
In the maternal circulatory system, we isolated placenta-derived exosomes, and it was determined that placenta-derived exosomes from preeclamptic patients (PE-exo) negatively impacted endothelial barrier integrity. The reduced expression of VE-cadherin in endothelial cells was subsequently linked to the compromised integrity of the endothelial barrier. Further examination uncovered a rise in exosomal miR-125b within PE-exo, directly suppressing VE-cadherin expression within HUVECs, consequently mediating the detrimental impact of PE-exo on endothelial barrier integrity.
Placental exosomes act as a bridge between impaired placentation and endothelial dysfunction, providing a novel perspective on the mechanisms of preeclampsia. Preeclampsia (PE) endothelial dysfunction is potentially influenced by exosomes containing placental microRNAs, opening avenues for potential therapeutic targets.
Placental exosomes establish a relationship between compromised placentation and endothelial dysfunction, providing insights into the mechanisms of preeclampsia. Preeclampsia's (PE) endothelial dysfunction may be influenced by placental-derived exosomal microRNAs, warranting further investigation as a potential therapeutic target.
Our study aimed to clarify the prevalence of maternal inflammatory response (MIR) and fetal inflammatory response (FIR) in the placentas of patients with intra-amniotic infection and intra-amniotic inflammation (IAI), utilizing amniotic fluid interleukin-6 (IL-6) levels at the time of diagnosis and the duration between diagnosis and delivery.
Employing a retrospective cohort study, data from a single center was analyzed. Amniocentesis was employed to diagnose IAI, in conjunction with the possibility of microbial invasion of the amniotic cavity (MIAC), in participants from August 2014 to April 2020. The criterion for IAI was amniotic IL-6 levels of 26ng/mL. MIAC's definition was established as a positive amniotic fluid culture result. IAI, coupled with the presence of MIAC, was used to identify an intra-amniotic infection. At the time of diagnosis, we ascertained the cutoff values for IL-6 concentration in amniotic fluid. Additionally, we evaluated the interval from diagnosis to delivery for MIR-positive cases presenting with intra-amniotic infection.
Diagnosis indicated an amniotic fluid IL-6 concentration of 158 ng/mL; the delivery was 12 hours after the diagnosis. click here Intra-amniotic infection cases showed a remarkable 98% (52/53) positivity rate for MIR, when using either of the two threshold values. The frequencies of MIR and FIR were statistically indistinguishable. Statistically lower MIR and FIR frequencies were observed in IAI cases devoid of MIAC as compared to those with intra-amniotic infection, unless neither cut-off value was exceeded.
We addressed the conditions of MIR- and FIR-positive intra-amniotic infection cases and those with IAI yet no MIAC, using the interval between diagnosis and delivery as a key element in our analysis.
We meticulously defined cases of intra-amniotic infection showing MIR and FIR positivity, along with instances of IAI without MIAC, while considering the timeframe from diagnosis to delivery.
Preterm or term prelabor rupture of membranes (PROM, PPROM or TPROM), exhibit an etiology that is, for the most part, unknown. This investigation sought to explore the correlation between maternal genetic variants and premature rupture of membranes (PROM), and to establish a method for predicting PROM based on these genetic factors.
For the case-cohort study (n = 1166), Chinese pregnant women were categorized into three groups: 51 with premature pre-labour rupture of membranes (PPROM), 283 with term premature rupture of membranes (TPROM), and 832 healthy controls. A weighted Cox model was applied to assess the relationship between the genetic variations—single nucleotide polymorphisms [SNPs], insertions/deletions, and copy number variants—and either premature pre-labor rupture of membranes (PPROM) or premature term premature rupture of membranes (TPROM). Gene set enrichment analysis (GSEA) served to investigate the underlying mechanisms. click here In order to generate a random forest (RF) model, suggestively significant GVs were used.
A particular variation in the PTPRT gene, rs117950601, demonstrated a powerful statistical relationship (P=43710).
The genetic marker rs147178603 displays a p-value of 89810.
The SNRNP40 variant (rs117573344) showed a compelling statistical link with a p-value of 21310.
PPROM was linked to the presence of (.), among other factors. A notable variant in the STXBP5L gene, designated as rs10511405, displays a P-value statistically measured at 46610, necessitating a more detailed analysis.
The presence of TPROM was associated with (.) GSEA findings highlighted the enrichment of PPROM-associated genes within the cell adhesion category, contrasting with TPROM-associated genes, which were primarily enriched in ascorbate and glucuronidation metabolic pathways. For the SNP-based radio frequency model predicting PPROM, the area under the receiver operating characteristic curve amounted to 0.961, accompanied by a sensitivity of 1000% and a specificity of 833%.
In maternal genes PTPRT and SNRNP40, GVs were found to be connected with PPROM. A similar link was established between STXBP5L GVs and TPROM. Cell adhesion was implicated in PPROM, and ascorbate and glucuronidation metabolism were also involved in TPROM. A SNP-based random forest model holds the potential to accurately predict PPROM occurrences.
Premature pre-term rupture of membranes (PPROM) was found to be linked to maternal genetic variations in PTPRT and SNRNP40 genes, while threatened premature rupture of membranes (TPROM) was associated with a maternal genetic variation in STXBP5L. The process of cell adhesion was connected to PPROM, whereas ascorbate and glucuronidation metabolism contributed to TPROM. An SNP-based random forest model appears to have the potential for reliably predicting PPROM.
The second and third trimesters of pregnancy are a frequent time for the development of intrahepatic cholestasis, or ICP. The disease's causative factors and diagnostic procedures are, unfortunately, presently unknown. A SWATH proteomic analysis of placental tissue was undertaken to discover proteins that might play a role in the etiology of Intrauterine Growth Restriction (IUGR) and negative pregnancy outcomes for the developing fetus.
For the case group (ICP group), postpartum placental tissue from pregnant women with intracranial pressure (ICP), subdivided into mild (MICP) and severe (SICP) ICP subgroups, were selected. The control group (CTR) was made up of healthy pregnant women. For the purpose of observing the histological changes of the placenta, hematoxylin-eosin (HE) staining was performed. Liquid chromatography-tandem mass spectrometry (LC-MS), together with SWATH analysis, was utilized to screen differentially expressed proteins (DEPs) in the ICP and CTR groups. Bioinformatics analysis was subsequently applied to ascertain the biological functions of these differential proteins.
A proteomic study contrasted the protein expression profiles of pregnant women with intracranial pressure (ICP) against healthy pregnant women, revealing 126 differentially expressed proteins (DEPs). Functional connections between the identified proteins were largely focused on the humoral immune system, cellular responses to lipopolysaccharide, antioxidant functions, and heme metabolism. Subsequent placental biopsies from patients with varying degrees of intracranial pressure highlighted 48 proteins with differing expression. Extrinsic apoptotic signaling pathways, blood coagulation, and fibrin clot formation are primarily regulated by DEPs through the interaction of death domain receptors and fibrinogen complexes. Western blot analysis, in agreement with proteomics data, showed a decrease in the expression levels of the proteins HBD, HPX, PDE3A, and PRG4.
The initial investigation into the placental proteome in ICP patients assists in understanding the evolving proteome, offering a new understanding of ICP pathophysiology.
