Cadherin family genes in non-small cell lung cancer: implications for diagnosis, prognosis, and targeted therapy.
Article in American journal of translational research, 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
objectivesThis study aimed to explore the diagnostic, prognostic, and therapeutic values of cadherin family genes (CDH1, CDH2, and CDH3) in non-small cell lung cancer (NSCLC) subtypes: lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC). METHODOLOGY: We analyzed the expression of CDH1, CDH2, and CDH3 in LUAD and LUSC using TCGA and TIMER2 data, and evaluated protein levels through immunostaining data from the HPA database. Gene expression across LUAD and LUSC stages was examined using GEPIA2. Methylation and mutation analyses were conducted vby OncoDB and cBioPortal, respectively. Prognostic significance was assessed through survival analyses using the KM Plotter tool. Gene enrichment and immune infiltration correlations were investigated using DAVID and GSCA databases. Knockdown experiments in PC9 cells were performed to assess the effects of CDH1 and CDH2 on cell proliferation, colony formation, and wound healing.
resultsThe expression of CDH1, CDH2, and CDH3 was significantly elevated in both LUAD and LUSC. Methylation analysis revealed reduced promoter methylation of cadherin genes in tumor samples compared to normal tissues. Mutational analysis showed that CDH2 exhibited the highest mutation frequency (63%), followed by CDH3 (23%) and CDH1 (19%). Survival analysis indicated that higher expression of CDH1, CDH2, and CDH3 was associated with poor prognosis in both LUAD and LUSC. Knockdown of CDH1 and CDH2 in PC9 cells resulted in reduced cell proliferation, colony formation, and impaired wound healing, with CDH2 knockdown showing more pronounced effects.
conclusionCDH1, CDH2, and CDH3 were upregulated in LUAD and LUSC, contributing to tumor progression and poor prognosis. Knockdown of CDH1 and CDH2 in PC9 cells impaired proliferation, colony formation, and wound healing, highlighting their potential as therapeutic targets.
