Molecular aspects of preeclampsia

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Reproductive Biology

Background:

• Preeclampsia origin hypotheses are diverse, but studying pregnancy diseases is challenging.
• Clinical presentation in the second/third trimester contrasts with early developmental origins.
• Animal models offer limited insight due to the disease's human-specific nature.

Purpose of the Study:

• To review current understanding of preeclampsia origins.
• To discuss clinical presentation and contributing pregnancy processes.
• To explore novel molecular techniques for preeclampsia research.

Main Methods:

• Review of existing hypotheses and clinical observations.
• Integration of advanced omics techniques: proteomics, genomics, lipidomics, metabolomics, mRNA microarrays.
• Analysis of pregnancy-related factors: placental implantation, endothelial adaptation, oxidative stress, genetics.

Main Results:

• Preeclampsia pathogenesis is multifactorial, involving early pregnancy events.
• Endothelial function is significantly altered, influenced by factors like relaxin, matrix metalloproteinases, endothelin, nitric oxide, angiogenetic factors, and TGF-b.
• Oxidative stress and genetic predispositions play crucial roles.

Conclusions:

• Understanding preeclampsia requires integrating traditional research with modern molecular approaches.
• Early pregnancy events, particularly placental implantation and endothelial adaptation, are key to preeclampsia development.
• Further research using omics technologies is vital for unraveling preeclampsia's complex etiology.
