Cure8 research brief
The study identifies Piezo1 in intestinal epithelial cells as a potential driver of intestinal fibrosis in IBD via a stiffness → ROS → partial EMT pathway, and suggests targeting Piezo1 or ROS could reduce fibrosis in preclinical models.
Researchers studying IBD fibrosis mechanisms, clinicians interested in fibrosis complications of IBD, and translational scientists exploring anti-fibrotic therapies.
The research uses DSS-induced fibrosis models, human IBD patient samples, and IEC-specific Piezo1 knockout mice to show Piezo1 is upregulated in fibrotic intestinal regions and that IEC-specific loss of Piezo1 reduced fibrosis without substantially changing chronic inflammation markers or fibroblast proliferation.
Mechanistic data from RNA-sequencing, metabolic assays, and stiffness-gradient hydrogels suggest Piezo1 activation by a stiffer matrix increases intracellular Ca2+ and reactive oxygen species, promoting a partial EMT in IECs.
Piezo1 knockout or antioxidant treatment (vitamin C) prevented these stiffness-induced changes in vitro, and high-dose oral vitamin C reduced fibrosis in vivo in the models used.
Results are from preclinical models (DSS mouse model, IEC-specific knockout mice, human tissue expression data, and in vitro stiffness assays). Abstract-level summary only; clinical relevance requires further study and human trials.
