Identification and validation of stemness-associated hub genes in cervical cancer: a bioinformatics and experimental study.
Article in World journal of surgical oncology, 2026. 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
Cancer stem cells (CSCs) are a subpopulation with self-renewal and differentiation capacity that drive the progression, recurrence, and therapeutic resistance of patients with cervical cancer (CC). However, the complete set of genes that maintain stemness in CC remains incompletely defined. We aimed to identify key stemness-related genes and evaluate their prognostic utility, immune associations, and drug sensitivity. Through literature mining and CellMarker 2.0, we identified 1345 stemness-associated genes that overlapped with differentially expressed genes (DEGs) from the TCGA-CESC dataset (log2FC > 2, p < 0.05), yielding 216 stemness-related DEGs. A protein-protein interaction network (STRING) and CytoHubba (MCC algorithm) revealed ten hub genes (HGs): CCNB1, CCNA2, BUB1B, UBE2C, KIF11, CCNB2, KIF23, CDC20, CDC6, and FOXM1. Gene ontology and KEGG analyses revealed predominant enrichment in cell cycle progression. Cox regression and Kaplan‒Meier analyses identified BUB1B, CCNA2, CDC20, FOXM1, and KIF23 as risk factors for poor overall survival, with KIF11 emerging as an independent prognostic factor. HGs overexpression significantly correlated with altered infiltration of 15 immune cell types, including negative associations with CD8 + T and NK cells. We identified 661 unique drugs/chemicals targeting these HGs, including FDA-approved repurposed agents. Experimental validation via RT‒PCR confirmed significant overexpression of FOXM1 and KIF11 in CC tissues and cell lines compared with normal samples. These stemness-associated HGs, particularly FOXM1 and KIF11, may serve as potential prognostic biomarkers and therapeutic targets, warranting further investigation of stemness-driven CC progression.
