Summary
Preeclampsia may stem from reduced placental 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2) activity, leading to fetal cortisol overexposure and growth restriction. This review explores factors affecting 11β-HSD2 function in preeclampsia.
Area of Science:
- Obstetrics and Gynecology
- Developmental Biology
- Endocrinology
Background:
- Preeclampsia poses significant risks to maternal and fetal health, with long-term implications.
- The precise etiology of preeclampsia remains incompletely understood.
- A leading hypothesis implicates reduced placental 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2) activity.
Purpose of the Study:
- To review and summarize factors influencing placental 11β-HSD2 activity in preeclampsia.
- To elucidate the mechanisms behind diminished 11β-HSD2 function in preeclamptic pregnancies.
Main Methods:
- Literature review of studies investigating placental 11β-HSD2.
- Analysis of factors affecting enzyme activity from gene expression to protein function.
Main Results:
- Reduced 11β-HSD2 activity is observed in preeclampsia.
- This reduction may lead to fetal overexposure to maternal cortisol.
- Cortisol overexposure can cause proapoptotic effects and fetal growth restriction, consistent with fetal hypotrophy in preeclampsia.
Conclusions:
- Diminished placental 11β-HSD2 function is a potential contributor to preeclampsia pathophysiology.
- Understanding the causes of reduced 11β-HSD2 activity is crucial for addressing fetal growth issues in preeclampsia.

01:33Hormonal Regulation
36.8K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
