Immune-related gene signatures of thin endometrium: a transcriptomic and single-cell study.
Observational study in Frontiers in endocrinology, 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
Background: Thin endometrium (TE) is associated with impaired endometrial receptivity and reduced rates of successful pregnancy. However, the immune-related transcriptomic alterations underlying TE remain poorly understood. This study aimed to identify differentially expressed genes (DEGs) and immune signatures associated with TE using integrated transcriptomic approaches. Results: Bulk RNA sequencing of endometrial tissues from TE patients and healthy controls revealed 57 DEGs. Gene Ontology enrichment analysis revealed the involvement of immune activation processes including leukocyte degranulation and natural killer (NK) cell-mediated cytotoxicity. Integration with publicly available single-cell RNA-seq data confirmed increased immune cell infiltration and altered gene expression in stromal and epithelial cell populations. Notably, significant upregulation of CORO1A, GNLY, and GZMA was observed in both datasets and validated using quantitative PCR. These genes are functionally related to cytotoxic immune responses. Canonical senescence markers were not detected, suggesting that immune dysregulation may play a more prominent role than senescence in TE pathogenesis. Conclusions: This study provides transcriptomic evidence that TE is associated with immune-related alterations, particularly those involving cytotoxic gene activation. The identified genes may serve as potential biomarkers or therapeutic targets for improving endometrial receptivity. These findings offer new insights into the molecular mechanisms of TE and lay the groundwork for future functional investigations. Clinical Trial Registration: Institutional Review Board Statement: This study was approved by the Ethics Committee of Shenzhen Nanshan Hospital (formerly known as Union Shenzhen Hospital of Huazhong University of Science and Technology at the time of ethical approval), under ethics approval number 072652 (approval date: 26 July 2019). The study was also registered with the China Clinical Trial Registration Center under registration number ChiCTR2000038068. The study was conducted in accordance with the Declaration of Helsinki.
