As presented in Figure 9, malnutrition induced by low protein diet (PM) for 11 weeks or by food-added 0.4 g/kg MSG for 8 weeks into NF pups significantly elevated Glial Fibrillary Acidic Protein (GFAB) content in brain by 50% and 200%, respectively, in brain homogenate as revealed by ELISA results. Here, GFAP is linked to malnutrition.
