1 · What the graph read from it

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.

2 · The registry

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

Background: Premature ovarian insufficiency (POI) is a persistent condition in young women characterized by early follicular development disorders and reduced fertility. Research has found that exosomes derived from human umbilical mesenchymal stem cells (hUCMSC-Exo) have significant tissue repair effects. This study aims to investigate the therapeutic effect and potential molecular mechanism of hUCMSC-Exo on POI. Methods: In vivo experiments were conducted by intraperitoneally injecting the chemotherapy drug cyclophosphamide (CTX) to establish a 14-day POI rat model. Serum hormone levels were measured using an enzyme-linked immunosorbent assay, and changes in ovarian tissue structure were analyzed using hematoxylin-eosin (HE) staining. Perls staining and transmission electron microscopy were used to assess changes in ovarian ferroptosis. In vitro experiments involved exposing theca interna cells (TICs) treated with CTX to normal and miR-26a-5p inhibitor-treated hUCMSC-Exo. The expression changes of PTEN, Nrf2, and GPX4, which are associated with ferroptosis, were analyzed using immunofluorescence, Western blot, and quantitative reverse-transcription polymerase chain reaction. Results: hUCMSC-Exo intervention can significantly repair the ovarian tissue structure and functional abnormalities in the model rats, especially ferroptosis. Further bioinformatics analysis revealed that the inhibition of the PTEN/GPX4 pathway-mediated ferroptosis in TICs might be the main mechanism through which exosomes exert their regulatory/therapeutic effects. In vitro experiments, where exosome miR-26a-5p was inhibited, further confirmed that the delivery of miR-26a-5p is crucial for the regulatory effect of exosomes. Conclusion: In conclusion, our results suggest that hUCMSC-Exos alleviates POI-related dysfunction of ovarian structure and function. The mechanism could be related to the transfers of miR-26a-5p and suppression of PTEN/GPX4 axis signaling-mediated autophagy of TICs. It provides a new perspective for developing treatment methods for patients with metabolic abnormalities related to POI.
