Summary: In the era of personalized medicine, research on fetal sex-specific mechanisms, particularly involving ncRNAs, is crucial for understanding pregnancy and complications. Studies have shown that miRNAs play a key role in regulating physiological processes in a sexually dimorphic manner, highlighting the need for further research on sex-specific ncRNAs in pregnancy and associated disorders.

Summary: Variations in telomere length have been linked to aging, stress, and diseases. This study investigated the association between placental telomere length and preeclampsia. The results suggest that placental telomere length is not significantly different between severe preeclampsia cases and healthy controls, but it is negatively correlated with gestational age and influenced by race.

Summary: Preeclampsia (PE) is a unique pregnancy-related disease that can cause maternal and perinatal mortality. Research suggests that natural killer (NK) cells play a central role in immune communication between the fetus and mother, and changes in their count or function may be the cause of PE. This review provides obstetricians with an updated report on the immunological roles of NK cells in PE and suggests that therapeutic measures targeting NK cells are necessary to maintain immune equilibrium.

Summary: Ovarian cancer and pregnancy expose the immune system to novel antigens, with both tumors and placenta utilizing extracellular vesicles (EVs) for cell-to-cell communication. EVs play a crucial role in promoting cell division and invasion, immunosuppression, and angiogenesis in both cancer and pregnancy.

Summary: This study found that the expression of KIR2DS5 was significantly lower in preeclampsia patients. Overexpression of KIR2DS5 facilitated the proliferation, migration, and invasion of trophoblasts. Mechanistic study demonstrated a positive relationship between KIR2DS5 and GM-CSF. A decrease in KIR2DS5 could reduce the expression of GM-CSF via the JAK2/STAT5 pathway, resulting in the occurrence of preeclampsia.

Summary: The apelinergic system is a highly conserved pleiotropic system that plays important roles in pregnancy and placenta-related complications. It is involved in the regulation of the adipoinsular axis, cardiovascular and central nervous systems, carcinogenesis, and embryo cardiogenesis and vasculogenesis during pregnancy. However, there are inconsistencies in the expression and circulating levels of its components in human placenta-associated preeclampsia.

Summary: Preeclampsia is a severe hypertensive disorder of pregnancy caused by placental villi pathology leading to widespread maternal endothelial dysfunction. Modulating trophoblast differentiation pathway through PPAR gamma-GCM1 axis may reduce excessive sFLT1 production and improve clinical outcomes. Pharmacological manipulation of PPAR gamma activity shows potential to rescue the antiangiogenic state of preeclampsia.

Summary: This study aims to characterize placental and circulating EV miRNA in gestational vascular complications (GVCs), and explores their involvement in GVCs and their potential use in distinguishing between placental and maternal pathologies. The results showed that hsa-miR-16-5p and hsa-miR-210 reflect the maternal pathophysiological status, while hsa-miR-29b-3p reflects the placental status. These findings suggest that EV-miRNAs are involved in GVCs and may be used as biomarkers to differentiate between pathologies of placental and maternal origins in preeclampsia.

Summary: Bioinformatics analysis identified potential miRNAs involved in the pathology of PE, with miR-513c-5p upregulated in the placenta of PE patients. miR-513c-5p inhibits LRP6 to regulate trophoblast function in PE.

Summary: SARS-CoV-2 infection in pregnant women leads to alterations in maternal and placental function, increasing the risk of preterm birth and caesarean delivery. Placentas of infected mothers show signs of vasculopathy and inflammation. The impact of maternal infection on the fetus and postnatal health is still unclear.
