Role of cadherin gene dysregulation in WNT signaling and nasopharyngeal carcinoma.
Article in Cell division, 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
backgroundNasopharyngeal carcinoma (NPC) is a malignancy associated with genetic alterations and tumor progression. Cadherin genes (CDH1, CDH2, and CDH3) play key roles in cell adhesion, migration, and tissue integrity, and their role in NPC remains underexplored. This study investigates the expression, mutation patterns, and prognostic significance of cadherin genes in NPC.
methodEight normal nasal cell lines and six NPC cell lines were cultured. Gene expression was analyzed using RT-qPCR and validated using GSCA and HPA databases. Promoter methylation, mutation, and CNV analyses were conducted using OncoDB and cBioPortal. Gene knockdown experiments were performed in 5-8 F NPC cells using siRNA targeting CDH1, CDH2, and CDH3, followed by cell proliferation, colony formation, and wound healing assays.
resultsCDH1, CDH2, and CDH3 were significantly upregulated in NPC cell lines, and high expression correlated with poor prognosis. Mutational analysis revealed mutations in 100% of HNSC or NPC samples, with CDH3 showing the highest mutation rate (44%). CNV analysis showed amplifications in cadherin gene regions. Knockdown of cadherin genes in 5-8 F and C666-1 cells significantly reduced cell proliferation, colony formation, and migration. Additionally, Cadherin gene knockdown upregulated AXIN1 and WNT3A, indicating involvement in the WNT signaling pathway.
conclusionCadherin genes are upregulated in NPC, associated with poor prognosis, and regulate key cancer-related processes. They represent potential diagnostic, prognostic, and therapeutic targets for NPC.
