Abstract

Diet has a profound effect on tissue regeneration in diverse organisms, and low caloric states such as intermittent fasting have beneficial effects on organismal health and age-associated loss of tissue function. The role of adult stem and progenitor cells in responding to short-term fasting and whether such responses improve regeneration are not well studied. Here we show that a 24 hr fast augments intestinal stem cell (ISC) function in young and aged mice by inducing a fatty acid oxidation (FAO) program and that pharmacological activation of this program mimics many effects of fasting. Acute genetic disruption of Cpt1a, the rate-limiting enzyme in FAO, abrogates ISC-enhancing effects of fasting, but long-term Cpt1a deletion decreases ISC numbers and function, implicating a role for FAO in ISC maintenance. These findings highlight a role for FAO in mediating pro-regenerative effects of fasting in intestinal biology, and they may represent a viable strategy for enhancing intestinal regeneration.

  • CPT1A is necessary for the improvement of ISCs upon fasting.

    “Indeed, the critical enzyme for fatty acid oxidation, carnitine palmitoyltransferase 1A (CPT1A), is necessary for this improvement of ISCs upon fasting214.”

  • The beneficial effect of fasting on ISCs is in part mediated by the induction of fatty acid oxidation.

  • Complete fasting (nutrient deprivation for 24 h) has beneficial effects on intestinal stem cell (ISC) function in both young and old mice.

    “Interestingly, complete fasting (nutrient deprivation for 24 h) has beneficial effects on ISC function — measured in this case by the ability of ISCs to regenerate in organoids — in both young mice and old mice214.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
