Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, Volume 20, Issue 6, Page 1494-1512, June 2026.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

ABSTRACT In endemic regions, unexplained small‐bowel bleeding should prompt consideration of parasitic etiologies even when routine investigations are unrevealing. Advanced small‐bowel imaging can directly demonstrate active sources of hemorrhage, enabling timely targeted therapy, preventing unnecessary procedures, and reducing morbidity associated ...
