Cadherin-mediated cell adhesion networks drive tumor growth and therapeutic responses in head and neck cancer.
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
backgroundCadherin family genes (CDH1, CDH2, and CDH3) regulate cell-cell adhesion and epithelial integrity and have emerging roles in tumorigenesis. However, their molecular and functional relevance in Head and Neck Squamous Cell Carcinoma (HNSC) remains incompletely defined.
methodsCadherin expression was evaluated in HNSC and normal oral epithelial cell lines using RT-qPCR. Multi-omics analyses of transcriptomic, methylation, mutation, and copy number variation (CNV) data were performed using TCGA datasets through GSCA, OncoDB, cBioPortal, and UALCAN. Prognostic significance was assessed using Kaplan-Meier and meta-analysis approaches. miRNA-mRNA interactions were predicted using miRNet and validated experimentally. Immune associations, drug sensitivity, and protein-protein interactions were explored using TISIDB, GSCA, STRING, and DAVID. Functional effects of CDH1 and CDH2 were evaluated by siRNA knockdown in FaDu and SCC9 cells, followed by proliferation, colony formation, wound healing, and xenograft assays.
resultsCDH1, CDH2, and CDH3 were significantly upregulated in HNSC cell lines and TCGA tumor samples, with CDH3 showing the highest diagnostic accuracy (AUC = 0.90). Hypomethylation and CNV amplification contributed to cadherin dysregulation, particularly for CDH2 and CDH3. Elevated cadherin expression correlated with poor overall survival. miR-200a-3p and miR-200c-3p were identified as shared regulators. Cadherin expression also showed associations with immune modulators and drug response. Functionally, CDH1 and CDH2 knockdown suppressed proliferation, migration, and tumor growth.
conclusionCadherin genes, particularly CDH3, show diagnostic and prognostic relevance in HNSC, while CDH1 and CDH2 contribute to tumor cell growth and migration. Further studies are required to determine their therapeutic potential.
