TP53 and Hypoglycemia: Finally, via p53 activation, aspartame inhibited a transcriptional coactivator, the peroxisome proliferator-activated receptor gamma coactivator 1 alpha, a master regulator of glucose and lipid metabolism, probably leading to changes in lipid profile in serum, total lipid accumulation, as well as an impairment in the gluconeogenesis in mouse liver, thus causing hypoglycemia.
