Fasting primes intestinal regeneration through Akkermansia muciniphila and propionate-driven epigenetic changes
By
Helen Piwnica-Worms
Summary
This scientific research article investigates how fasting enhances small intestinal regeneration after damage (e.g., radiation) through a microbiome–metabolite–chromatin axis. The study identifies that fasting increases the abundance of Akkermansia muciniphila (AKK), a beneficial gut bacterium. AKK produces propionate, a short-chain fatty acid that drives epigenetic changes by modifying chromatin, thereby priming the small intestine for regeneration after injury. The research establishes a mechanistic link between fasting, the gut microbiome, metabolite production, and epigenetic regulation of tissue repair.

· 3 pulledFasting changes the gut microbiome, but how these changes help the body recover from damage is not well understood.
We found that fasting increases a helpful bacterium, Akkermansia muciniphila, which produces propionate, which drives epigenetic changes by modifying chromatin.
Fasting enhances small intestinal regeneration after radiation, but the contribution of the gut microbiome to this process remains uncharacterized.
