1 · What the graph read from it

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.

2 · The registry

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

backgroundColorectal cancer (CRC) is a leading cause of cancer mortality, with treatment resistance often driven by molecular heterogeneity and an immunosuppressive tumor microenvironment (TME). Post-translational modifications (PTMs) regulate key oncogenic processes, but their comprehensive role in CRC progression and immune evasion remains unexplored.

methodsWe integrated multi-omics data from bulk RNA-seq (GEO/TCGA, n = 1,783), single-cell transcriptomics (41,143 cells), and Mendelian randomization. Differential expression, GSVA, and machine learning (LASSO/SVM/Random Forest) were used to identify PTM-associated signatures. Functional validation included spatial transcriptomics, and immune profiling.

resultsMulti-omics analysis identified dysregulation in 80% of PTM pathways in CRC, with ubiquitination sustaining Wnt/β-catenin signaling and GALNT6-mediated glycosylation driving immune evasion through PD-L1 stabilization and CD8 + T cell exclusion. Single-cell analysis revealed GALNT6-specific enrichment in immune-excluded goblet cells (p < 0.05). Machine learning derived a 5-gene PTM Activity Signature (CCNB1IP1, GALNT6, NEDD4L, PSMD14, UBE2C) that distinguish between patients with diseases and those without (AUC = 1.00). GALNT6 was validated as a causal risk factor (OR = 1.10, 95%CI:1.01-1.18), with its inhibition synergizing with anti-PD-1 to enhance CD8 + T cell infiltration (p < 0.01).

conclusionThis study establishes PTM networks as central regulators of CRC progression and immune resistance. The PTM-AS framework enables precision subtyping, while GALNT6 emerges as a novel therapeutic target for overcoming immunotherapy resistance.
