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

Epigenetic drift is a key feature of aging and is associated with age-related diseases including cancer, yet the underlying molecular mechanisms remain unclear. Here, by analyzing DNA methylation and gene expression data from healthy and cancerous human colon samples, we identify an aging and colon cancer-associated DNA methylation (DNAm) drift. We find evidence that this drift is conserved in the mouse intestinal epithelium, where we demonstrate its origin within intestinal stem cells and identify its cell-intrinsic and non-mitotic characteristics, finding that its expansion is regulated via crypt clonality and fission. Mechanistically, we find that this drift is driven by age-related inflammation and reduced Wnt signaling, which dysregulate iron metabolism and impair TET activity. Despite CpG-level heterogeneity, we find that DNAm changes are consistent at the gene level, suggesting potential functionality. Our findings shed light on the epigenetic mechanisms of aging and provide a mechanistic basis for the hypermethylation observed in cancer.
