Dietary fat alters goblet cell function and microbial bile acid metabolism to promote intestinal lipid absorption in mice.
Article in Nature microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Dietary fat reshapes host-microbiota interactions, yet the upstream events that mediate overnutrition-driven microbiome alterations and metabolic dysfunction remain unclear. Here we compared mouse models of diet-induced and genetic obesity using multi-omics to identify the colonic mucus niche as an early, diet-sensitive driver of metabolic dysfunction. Excessive dietary lipids impaired glutamine metabolism and redox homeostasis in goblet cells, thinning the mucus layer and depleting the mucus-adapted symbiont Akkermansia muciniphila while expanding the bile-acid-transforming bacterium Clostridium scindens. Altered bile acid composition along the enterohepatic axis activates FXR-PLIN2 signalling in the small intestine and increases fat absorption. In parallel, enterocytes upregulate the PPARα-dependent uptake pathway that supports luminal lipid entry. Supplementation with glutamine restored goblet cell function and the gut microbiota-derived bile acid pool, thereby reducing intestinal FXR activation and lipid uptake. These findings reveal that dietary fat impairs colonic goblet cell function and reshapes microbial bile acid metabolism, influencing small-intestinal fat absorption.
