SCN3B is an Anti-breast Cancer Molecule with Migration Inhibition Effect.
Article in Biochemical genetics, 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
Breast cancer is a prevalent and highly heterogeneous malignancy that continues to be a major global health concern. Voltage-gated sodium channels are primarily known for their role in neuronal excitability, but emerging evidence suggests their involvement in the pathogenesis of various cancers, including breast cancer. However, the effect of β-subunits on breast cancer cells is not yet studied. SCN3B, as a modulatory subunit, is of particular interest due to its less understood role in cancer biology. This research comprehensively investigates the clinical associations, diagnostic potential, and functional role of SCN3B in breast cancer, shedding light on its diverse implications from patient outcomes to molecular mechanisms. Our methods included clinical data analysis from The Cancer Genome Atlas (TCGA) breast cancer dataset, diagnostic analysis through ROC curves, differential gene expression analysis, SCN3B expression assessment in cell lines, overexpression experiments, and functional assays. Additionally, we constructed a protein-protein interaction network to explore potential mechanisms underlying SCN3B's impact. The study revealed significant clinical associations between SCN3B expression and various parameters such as tumor stage, race, age, histological type, molecular subtype, and hormone receptor status. SCN3B demonstrated strong diagnostic potential with an AUC of 0.95. It influenced the expression of over 800 genes, primarily associated with cell migration and extracellular matrix interactions. SCN3B exhibited distinct expression patterns between normal and breast cancer cell lines and successfully overexpressed in various breast cancer cell lines. This overexpression inhibited cell migration and invasion. Our research emphasizes SCN3B's clinical relevance, diagnostic potential, and influence on cell behavior in breast cancer, offering insights into its multifaceted role and therapeutic implications.
