A principal mechanism of action involves the modulation of gene and protein expression governing tight-junction signaling pathways within intestinal IECs, thereby influencing barrier assembly, permeability, and overall epithelial integrity (166)
A limitation with the use of GLUTag cells, as well as other models for epithelial cells, is that the cells have lost their polarization, which may affect the amino acid sensing mechanisms, as different amino acid transporters are situated on the apical compared to the basolateral membrane [28]
What do I mean by that
