This study identifies 44 senescence-related differentially expressed genes in early-onset preeclampsia (EOPE) placentas. Key hub genes, including LEP, ENG, MIF, and CYBB, are predominantly expressed in trophoblasts and immune cells.
Background
Early-onset preeclampsia (EOPE) is a severe hypertensive disorder of pregnancy that poses significant risks for maternal and fetal health. The role of placental senescence in EOPE pathogenesis has been increasingly recognized, yet the specific gene signatures involved remain poorly defined.
Data Highlights
Gene
Expression Pattern
LEP
Predominantly expressed in trophoblasts
ENG
Predominantly expressed in immune cells
MIF
Hub gene identified in EOPE
CYBB
Hub gene identified in EOPE
Key Findings
A total of 44 senescence-related differentially expressed genes were identified in EOPE placentas.
These genes are mainly enriched in cell proliferation-related pathways.
LEP, ENG, MIF, and CYBB were identified as hub genes in the study.
Senescence-associated activity was primarily enriched in the trophoblast lineage.
LEP is implicated in syncytiotrophoblast senescence and secretory dysfunction.
Clinical Implications
Understanding the role of these genes in placental dysfunction could provide insights into the mechanisms of EOPE.
Conclusion
The findings indicate a relationship between placental senescence and early-onset preeclampsia, warranting further investigation into the molecular mechanisms involved.
