Research Abstract

We have presented that feeding neonatal mice with glutamine-deleted artificial milk formula induced high incidence of colonic hemorrhage due to the epithelial cell death, applying a new nipple-bottle feeding system for newborn mice. IEC6 rat intestinal epithelial cells cultured with low concentration of glutamine underwent apoptosis.
Glutamine deprivation might cause instability of the intestinal epithelial alignment by apoptosis.
