A link between TP53 polymorphisms and metabolism

Abstract

Besides being a critical tumor suppressor, the TP53 gene also plays a role in metabolism and recent studies in humans have implicated the codon 72 polymorphism of TP53 in this role. Using a humanized knock-in mouse model for these TP53 variants, we show that this polymorphism has a significant impact on the metabolic response to a high-fat diet.
