Role of oxysterol 4β-hydroxycholesterol and liver X receptor alleles in pre-eclampsia.

Summary: Pregnant women sometimes develop a dangerous condition called pre-eclampsia, which causes high blood pressure and affects the placenta. Scientists wanted to know if a specific fat molecule in the blood (called 4βHC) or certain genes (called LXRs) help control this blood pressure. They looked at blood and placenta samples from hundreds of mothers. They found that this fat molecule and these genes do not actually play a big role in causing the high blood pressure. However, they did find that some related genes act differently in the placentas of women with the condition. This helps doctors better understand how the placenta works during pregnancy, even if it doesn't lead to a new blood pressure treatment right away.
