Investigation of Urotensin II expression in placenta and umbilical cord in pregnancies with intrauterine growth restriction by histological and biochemical methods
Objective
In this study, it was aimed to investigate Urotensin II in intrauterine growth restriction (IUGR) and its connection to autophagy and/or apoptosis in placenta and umbilical cord by immunohistochemical and biochemical methods.
Materials and methods
The study included 30 healthy pregnant women and 30 pregnant women with IUGR, aged 19–45, at Atatürk University Gynecology Clinic. Samples were collected from placenta, umbilical cord, maternal blood, and umbilical cord blood during delivery. Histopathological examination was carried out on placenta and umbilical cord, and UTII, Beclin 1, and caspase 3 expressions were analyzed in these tissues. Biochemical analysis was performed on maternal and umbilical cord serum samples.
Results
In healthy placentas, normal villus formation was seen, but those with IUGR showed accelerated villus maturation, causing inadequate nutrition and development. IUGR placentas had fibrin deposition, villous edema, syncytial nodes increase, and intervillous distance. Umbilical cords of IUGR group had differences in vessel wall thickness, arterial lumens, and vessel number. Higher levels of UTII, Beclin 1, and caspase 3 were found in IUGR placenta and cord. Beclin 1 and caspase 3 levels were significantly higher in IUGR group compared to controls, while UTII levels were not significantly different in maternal and cord serums.
Conclusion
As a result of our findings, UTII increase in placenta and umbilical cord may lead to IUGR formation by inducing autophagy and apoptosis.
期刊介绍：
Placenta publishes high-quality original articles and invited topical reviews on all aspects of human and animal placentation, and the interactions between the mother, the placenta and fetal development. Topics covered include evolution, development, genetics and epigenetics, stem cells, metabolism, transport, immunology, pathology, pharmacology, cell and molecular biology, and developmental programming. The Editors welcome studies on implantation and the endometrium, comparative placentation, the uterine and umbilical circulations, the relationship between fetal and placental development, clinical aspects of altered placental development or function, the placental membranes, the influence of paternal factors on placental development or function, and the assessment of biomarkers of placental disorders.
