Restoring Prostacyclin/PGI2-PTGIR signaling alleviates intestinal fibrosis in Crohn's disease via fibroblast-specific YAP/TAZ inhibition.

ABSTRACT:

Background and aims

Intestinal obstruction caused by fibrosis is a common and serious complication of Crohn's disease (CD). Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motifs (TAZ), the transcriptional effectors of the Hippo signaling pathway, have emerged as key drivers of intestinal fibrosis. Systematic inhibition of YAP/TAZ failed to combat fibrotic progression, probably due to the vital role of epithelial YAP/TAZ in intestinal homeostasis.

Methods

Enzyme-Linked Immunosorbent Assay (ELISA) and immunohistochemical staining were used to detect serum Prostaglandin I2 (PGI2) levels and PGI2 Receptor (PTGIR) in clinical samples derived from CD patients. Dual luciferase reporter and Cut & Run assays were performed to explore the transcriptional
