Maternal causation of early-onset pre-eclampsia: excessive endometrial gland-derived apolipoprotein D induces placental ferroptosis and developmental abnormalities.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEarly-onset pre-eclampsia (ePE) is a severe pregnancy complication characterized by dysregulated trophoblast functions and impaired placentation during early pregnancy, leading to substantial maternal and fetal morbidity. While circumstantial evidence indicates defective secretion from endometrial glands impairs placental development, direct evidence linking maternal glandular dysfunction to ePE pathogenesis remains elusive.
methodsWe established endometrial glandular organoids from women with ePE and healthy pregnancies, analyzing their secretomes by iTRAQ-based proteomics, RNAseq, and spatial transcriptomics. Functional effects of organoid secretomes on trophoblasts were examined in vitro. An endometrial-specific apolipoprotein D (APOD) knock-in mouse model was studied in vivo. APOD levels in first-trimester serum samples from women who later developed ePE were compared to healthy pregnancies.
resultsSecretomes from ePE derived endometrial organoids impeded spiral artery remodeling. Multiomic analyses revealed increased APOD production in both ePE organoids and decidual tissues. APOD overexpression disrupted trophoblast functions and endothelial vascular remodeling in vitro, and recapitulated ePE phenotypes in an APOD knock-in mouse model through PI3K/Akt-mediated placental ferroptosis and potential ER stress induction. Ferroptosis inhibition with Fer-1 rescued placental defects and PE symptoms in APOD knock-in mice. Elevated APOD levels in first-trimester serum samples from women who later developed ePE suggest its potential as an early biomarker.
conclusionThis study provides the first direct evidence linking dysregulated endometrial gland function to defective placentation and ePE. APOD was identified as a crucial endometrial gland-secreted factor contributing to ePE, suggesting its potential as an early biomarker and therapeutic target.
