Distinct TYRO3 and PROS1 expression levels contribute to preeclampsia pathogenesis.

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
Preeclampsia (PE) is a severe placental complication occurring after the 20th week of pregnancy. PE is associated with inflammation and an increased immune reaction against the fetus. TYRO3 and PROS1 suppress inflammation by clearing apoptotic cells. Disruptions in TYRO3/PROS1 signaling may increase the risk of PE. This study investigated the role of TYRO3/PROS1 signaling in the development of PE using healthy placentae (HP) and preeclamptic placentae (PP) of six pregnant women each. Tissue morphology using hematoxylin and eosin (H&E), TYRO3, MERTK, PROS1, and GAS6 mRNA levels using qPCR and localization and expression levels of TYRO3 and PROS1 using immunohistochemical staining (IHC) were evaluated. The study results show that the levels of TYRO3, MERTK, PROS1 and GAS6 mRNA, as well as TYRO3 protein, increased in PE. TYRO3 expression was observed in extravillous trophoblast (EVTs) and syncytiotrophoblast cells (SCTs). PROS1 was observed in HP fetal vessels through IHC while absent in PP. The reduced presence of PROS1 in the cytotrophoblast layer in PE may indicate a compromised blood-placental barrier. The absence of PROS1 in fetal vessels may suggest potential complement activation and thrombosis. TYRO3, MERTK, PROS1 and GAS6 may help balance impaired inflammation, apoptosis, thrombosis, complement activation and the blood-placental barrier in PE.
