Effects of butyrate on intestinal barrier function in a Caco-2 cell monolayer model of intestinal barrier

Peng, Luying, He, Zhenjuan, Chen, Wei, Holzman, Ian R, Lin, Jing·2007·Pediatric Research

Abstract

Production of short-chain fatty acids (SCFA) in the intestinal lumen may play an important role in the maintenance of the intestinal barrier. However, overproduction/accumulation of SCFA in the bowel may be toxic to the intestinal mucosa and has been hypothesized to play a role in the pathogenesis of neonatal necrotizing enterocolitis (NEC). By using a Caco-2 cell monolayer model of intestinal barrier, we report here that the effect of butyrate on the intestinal barrier is paradoxical. Butyrate at a low concentration (2 mM) promotes intestinal barrier function as measured by a significant increase in transepithelial electrical resistance (TER) and a significant decrease in inulin permeability. Butyrate at a high concentration (8 mM) reduces TER and increases inulin permeability significantly. Butyrate induces apoptosis and reduces the number of viable Caco-2 cells in a dose-dependent manner. Intestinal barrier function impairment induced by high concentrations of butyrate is most likely related to butyrate-induced cytotoxicity due to apoptosis. We conclude that the effect of butyrate on the intestinal barrier is paradoxical; i.e. whereas low concentrations of butyrate may be beneficial in promoting intestinal barrier function, excessive butyrate may induce severe intestinal epithelial cell apoptosis and disrupt intestinal barrier.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Butyrate improved barrier function at lower doses, but reduced barrier function at higher doses in Caco-2 cells.

    “Similarly, butyrate improved barrier function at lower doses, but reduced barrier function at higher doses in Caco-2 cells.80”

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.
