ZC3H12D gene expression exhibits dual effects on the development and progression of lung adenocarcinoma.
Article in Scientific reports, 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
While precision oncology requires robust biomarkers, current predictors for lung adenocarcinoma (LUAD) often show limited clinical utility. This study investigates the multifaceted roles of ZC3H12D, a novel immunomodulatory molecule, in LUAD progression and tumor microenvironment regulation. Multi-omics analyses integrated ZC3H12D transcriptomic (511 tumors vs 59 normals), proteomic (74 tumors vs 69 normals), and single-cell RNA-seq data (15 tumors vs 11 normals). Immunohistochemistry validated ZC3H12D expression in 51 matched pairs. Computational biology approaches assessed immune infiltration, genomic instability (TMB/MSI/HRD), and pathway enrichment. Functional validation employed ZC3H12D knockdown in PC9 cells with colony formation and transwell assays. Multi-omics verification confirmed ZC3H12D upregulation in LUAD at both mRNA and protein levels (p < 0.001), with single-cell resolution revealing predominant localization in tumor-infiltrating immune cells. Moreover, ZC3H12D expression positively correlated with immune regulatory genes while inversely associating with genes involved in cellular respiration. Its expression was also linked to clinical markers such as TMB, MSI, HRD, tumor purity, and ploidy. Notably, high ZC3H12D expression revealed Immune-infiltrated microenvironment and favorable prognosis, despite silencing ZC3H12D resulted in significant inhibition of tumor cell proliferation and invasion in vitro (p < 0.001). Our findings demonstrate that high ZC3H12D expression in immune cells appears to enhance antitumor immune activity, whereas lower expression in malignant cells contributes to reduced cellular proliferation and migration. This spatial duality challenges conventional biomarker paradigms and provides mechanistic insights for developing cell type-targeted therapies.
