Duchenne muscular dystrophy gene product expression is associated with survival in head and neck squamous cell carcinoma.

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
Mutation of the Duchenne muscular dystrophy (DMD) gene causes neuromuscular disorders, but increasing evidence has implicated DMD in the development and progression of several major cancer types. This study investigates the prognostic and biological significance of DMD expression in head and neck squamous cell carcinoma (HNSCC). Analysis of The Cancer Genome Atlas (TCGA) data revealed that high DMD expression correlates with improved overall (median survival difference: 22 months, p = 0.0083) and progression-free (p = 0.0237) survival. The Dp71ab transcript is most strongly associated with better outcomes (median overall survival: 42 months, p = 0.0007). Notably, DMD expression levels stratify HPV-positive patients, identifying a DMD low/HPV-positive subgroup with poor outcomes. Immunohistochemical analysis of 50 HNSCC tissue cases confirmed dystrophin localisation in the nucleus and cytoplasm, with high nuclear expression linked to longer overall survival (mean difference: 31 months, p = 0.0497). Functional assays in HNSCC cells showed that Dp71ab overexpression disrupts nuclear morphology and reduces proliferation. Differential gene expression analysis additionally identified 388 upregulated and 30 downregulated genes, with pathways linked to muscle processes, ribosome biogenesis and non-coding RNA regulation. These findings highlight DMD as a potential biomarker and/or therapeutic target in HNSCC, warranting further mechanistic studies of Dp71 isoforms.
