MOB1A/B Loss Disrupts Intestinal Epithelial Homeostasis
2026-08-26
Bae et al. show that intestinal epithelial depletion of MOB1A/B causes stem-cell loss and degenerative remodeling by simultaneously suppressing Wnt activity and activating BMP/TGF-β signaling through enhanced YAP activity. Inhibitor experiments indicate that BMP and TGF-β signaling contribute to the phenotype, although blocking these pathways restores secretory differentiation only partially and does not rebuild the intestinal stem-cell pool.
