Lnc-HZ05 Suppresses Trophoblast Cell Migrasome Formation by Disrupting TGFβ2 Pathway in Unexplained Recurrent Miscarriage.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Unexplained recurrent miscarriage (RM) is a clinical challenge due to its unclear pathogenesis. TGFβ2 plays essential roles in reproductive events. Migrasomes are newly identified organelles. Herein, whether TGFβ2 might regulate trophoblast cell migrasome formation (MF) and miscarriage, and the epigenetic regulation mechanisms, is completely unknown. In this study, we find that TGFβ2-mediated MF is suppressed and is negatively associated with RM based on a case-control study, further confirmed by a mouse model with miscarriage. In cellular mechanism, TGFβ2 promotes trophoblast cell MF, specifically suppressed by lnc-HZ05. In details, lnc-HZ05 (1) suppresses FOXP3-mediated TGFβ2 transcription, (2) promotes autophagy degradation of TGFβ2, and (3) impairs TGFβ2/TGFβR2 interactions by binding to both proteins with 1-83 nt of lnc-HZ05, three of which suppress TGFβ2 pathway. Meanwhile, DNMT1 suppresses FOXP3-mediated lnc-HZ05 transcription, forming a FOXP3/lnc-HZ05 negative regulatory loop. The cellular mechanisms are consistent with those in RM villous tissues. Moreover, higher levels of TGFβ2 protein and lnc-HZ05 in serum well predict miscarriage risk. Supplement with murine Tgfβ2 protein recovers MF and alleviates mouse miscarriage. Collectively, this study discovers novel biological mechanisms of lnc-HZ05 and TGFβ2 pathway in the pathogenesis of RM and provides potential targets for prediction and therapy of RM.
