HIF-1 attenuates high-fiber diet-mediated proliferation and stemness of colonic epithelium.
Article in Gut microbes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 complex interplay between diet, microbiota, and host is exemplified by the effects of dietary fiber on the intestine. Inulin ingestion triggers epithelial changes in the colon that depend on microbiota-derived molecules, including enhanced proliferation, increased mucus production, and elevated antimicrobial peptide secretion. Here we employed a multilayered and multi-omics approach, including dietary interventions, intestinal organoids, and both genetic and pharmacological interventions to investigate the impact of inulin on two aspects of diet-microbiota-host interactions: intestinal hypoxia and hypoxia-inducible factor (HIF)-1 signaling in intestinal epithelial cells (IECs). We found that inulin, a soluble fiber, promotes intestinal hypoxia, stabilizing HIF-1 in IECs in a microbiota- and host-dependent manner. Furthermore, we show that HIF-1 stabilization modulates intestinal stem cell (ISC) function through metabolic reprogramming in a microbiota-dependent manner. Our findings reveal an unrecognized role for HIF-1 in orchestrating microbiota-dependent epithelial metabolism and proliferation in the colon, underscoring the complexity of diet-microbiota-host interactions.
