ZBTB10 as a potential prognosis biomarker and correlates with the tumor immune microenvironment in stomach adenocarcinoma.
Article in BMC gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundZBTB10 is a member of the zinc finger and bric-a-brac/tramtrack/broad (ZBTB) domain-containing protein family, reported to be associated with tumorigenesis and progression. However, its specific roles in oncogenesis, prognosis, and immune infiltration in stomach adenocarcinoma (STAD) remain to be elucidated.
methodsWe analyzed ZBTB10 mRNA and protein expression profiling in STAD tissues using various bioinformatics tools, including TIMER2, GEO, Human Protein Atlas (HPA) databases, and R software. Survival analysis was performed through the Kaplan-Meier plotter. UALCAN and TCGA databases were used to evaluate the association of ZBTB10 expression with clinicopathological characteristics. Genetic alterations of ZBTB10 in human tumor samples were analyzed using the cBioPortal database. The correlation between ZBTB10 expression and immune cell infiltration was assessed using the TISIDB and CIBERSORT algorithms. Gene Set Enrichment Analysis (GSEA) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway were applied to investigate the potential mechanism of ZBTB10 in STAD. Additionally, in vitro assays such as CCK-8, colony formation, and wound healing assays were performed to determine the biological role of ZBTB10 in STAD cells. Multiple immunohistochemistry (mIHC) was applied to characterize the association between immune cell infiltration and ZBTB10 expression in STAD tumor tissues.
resultsOverall, ZBTB10 was differentially expressed in STAD compared to adjacent normal tissues, and higher ZBTB10 expression correlated with poorer overall survival (OS). Furthermore, GSEA and KEGG analysis suggested that ZBTB10 was predominantly involved in focal adhesion, PI3K-Akt signaling, and MAPK signaling pathways, suggesting its potential role in promoting tumor growth and progression. Moreover, based on the CIBERSORT algorithm, the expression of ZBTB10 was positively related to the levels of B cells, CD4 + T cells, M1 macrophages, and neutrophil cells. Meanwhile, ZBTB10 expression appeared to be negatively associated with tumor mutation burden (TMB) and microsatellite instability (MSI) in STAD, both of which influenced the efficacy of tumor immunotherapy. In vitro experiments demonstrated that ZBTB10 knockdown significantly inhibited tumor cell proliferation and invasion, and organoid area in STAD cell lines. The immune cell signature of CD45 was more prevalent with ZBTB10 expression in tumor tissue sections compared to adjacent normal tissues from STAD patients.
conclusionsUpregulated ZBTB10 is significantly correlated with poor survival outcomes and immune infiltration in STAD, revealing that ZBTB10 may serve as a promising prognostic biomarker and a potential target for immunotherapy in STAD.
