Protein Turnover in Epithelial Cells and Mucus along the Gastrointestinal Tract Is Coordinated by the Spatial Location and Microbiota (Cell Reports)

Arike et al. report a turnover rate of >3,000 and expression of >5,000 proteins in epithelial cells and mucus along the mice gastrointestinal tract. Protein turnover rate is faster in the small intestine than in the colon and slower in germ-free animals.
