Mechanism of hsa_circ_0069443 promoting early pregnancy loss through ALKBH5/FN1 axis in trophoblast cells.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Studies have shown that circRNAs play an important regulatory role in trophoblast function and embryonic development. Based on sequencing and functional experiments, we found that hsa_circ_0069443 can regulate the function of trophoblast cells, and its presence is found in the exosomes secreted by trophoblast cells. It is known that exosomes mediate the interaction between the uterus and embryo, which is crucial for successful pregnancy. We found that trophoblast cell-derived exosomes overexpressing hsa_circ_0069443 promoted the migration and invasion of endometrial stromal cells as well as the EMT process of endometrial glandular epithelial cells, and this process promotes embryo implantation and adhesion, thus proving that a decrease in hsa_circ_0069443 may be the key factor leading to early pregnancy loss. This study also found that hsa_circ_0069443 can bind to the RNA-binding protein demethylase ALKBH5, affecting the overall m6A level of trophoblast cells, and hsa_circ_0069443 and ALKBH5 can regulate the expression level of FN1, verifying the role of the 0069443/ALKBH5/FN1 axis in trophoblast cells and endometrial stromal cells. In summary, this study demonstrates that hsa_circ_0069443 may be a key factor leading to early pregnancy loss, and the regulation of the hsa_circ_0069443/ALKBH5/FN1 axis may provide new insights into early diagnostic markers for early pregnancy loss.
