Article Synopsis
  • Preeclampsia (PE) is a pregnancy-related condition that leads to high blood pressure and can cause serious health issues for both mothers and babies, yet its exact cause is still unknown.
  • This study involved 38 pregnant women categorized into three groups: those with normal pregnancies, early-onset PE, and late-onset PE, focusing on analyzing the cells and mitochondria in the placenta.
  • Findings showed that early-onset PE placentas had increased levels of certain mitochondrial-related proteins and DNA copy numbers, indicating that changes in mitochondrial activity may play a significant role in how PE develops.

Introduction: The placental bed plays a key role in placentation during gestation. Most studies investigated the expression of angiogenic factors in the placenta, but their expression and potential role in the placental bed have not been investigated adequately.

Objectives: The aim of the study was to examine the expression of the fact is that Apo-Cas is apoptotic marker and VEGF in placental bed of pregnancy with early, late-onset PE and without PE.

Introduction: Preeclampsia is a major complication affecting at least 3-4% of all pregnancies and is globally responsible for approximately 50,000 maternal deaths annually. Currently the main cause of preeclampsia is a shallow placentation, with abnormal invasion of cytotrophoblasts and incomplete remodeling of placenta-supplying maternal uterine spiral arteries. However, up to 20weeks, these processes are asymptomatic, although they are accompanied by the release of various macromolecules in the bloodstream of the mother, which are potential biomarkers of disease, needed to detect.
