Insights

Fibroblast growth factor 19 (FGF19) enhances intestinal adaptation in short bowel syndrome (SBS) by improving epithelial barrier and mitochondrial function, and regulating cell adhesion.

Area of Science:

  • Gastroenterology
  • Pediatric Medicine
  • Molecular Biology

Background:

  • Intestinal adaptation is crucial for pediatric patients with short bowel syndrome (SBS).
  • The role of fibroblast growth factor 19 (FGF19) in SBS intestinal adaptation is not well understood.

Purpose of the Study:

  • To investigate the hormonal effect of FGF19 on intestinal adaptation in pediatric short bowel syndrome.

Main Methods:

  • Transcriptomic analyses of in vivo pediatric SBS patient datasets (with and without intact ileocecal valve).
  • In vitro studies using short bowel syndrome patient-derived enteroids (SBS-PDEs) treated with recombinant human FGF19 (rhFGF19).

Main Results:

  • Identified differentially expressed genes (DEGs) related to metabolic pathways and cell adhesion in vivo.
  • rhFGF19 treatment in SBS-PDEs improved epithelial barrier integrity and mitochondrial respiration.
  • 56 overlapping DEGs between in vivo and in vitro studies were primarily associated with cell adhesion.

Conclusions:

  • FGF19 influences intestinal adaptation beyond metabolism.
  • FGF19 enhances epithelial barrier function and mitochondrial respiration in SBS.
  • FGF19 plays a role in regulating cell adhesion for intestinal maturation.
