Chrono-atlas of cell-type specific daily gene expression rhythms in the regenerating colon.
Article in Nature communications, 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
The circadian clock is present throughout the body, including the intestine, where it regulates daily physiology through rhythmic gene expression. The large intestine (colon) is composed of many functionally distinct cell types; how daily rhythms in transcript abundance are coordinated in specific cells is not known. Using single-cell transcriptomics, we analyzed 24-hour gene expression rhythms in all major cell types of the colon following injury. Such rhythms are not uniformly distributed: rhythmic genes, including circadian clock components, clock targets, and systemic response programs, differ in their timing, and are cell-type-, region-, or injury- specific. Compared to stromal and muscle cells, which exhibit robust circadian clock rhythms, epithelial cells show weaker oscillations. During regeneration, cells of the epithelium, stroma, and immune system display strong biphasic rhythms in metabolic, protein processing, and temperature response genes, and epithelial clocks are reprogrammed to become 12-hours antiphasic in timing. Our data reveal unexpected complexity in the colon and provide a resource by identifying the cellular source of 24-hour transcript rhythms.
