The plasticizer di-(2-ethylhexyl)phthalate (DEHP) affects reproductive development, glycogen and lipid metabolism. Whereas liver is a main DEHP target in adult rodents, the potential impact on metabolic programming is unknown. Effects of in utero DEHP exposure on liver development were investigated upon treatment of pregnant CD-1 mice on gestational days (GD)11–19. F1 mice were examined at post-natal days 21 (weaning) and 35 (start of puberty): parameters included liver histopathological, immunocytochemical and α-fetoprotein (AFP) gene expression analyses. In utero DEHP exposure altered post-natal liver development in weanling mice causing significant, dose-related (i) increased hepatosteatosis, (ii) decreased glycogen storage, (iii) increased β-catenin intracytoplasmic localization (females only). At puberty, significantly decreased glycogen storage was still present in males. A treatment-induced phenotype was identified with lack of glycogen accumulation and intracytoplasmic localization of β-catenin which was associated with increased AFP gene expression. Our findings suggested that DEHP alters post-natal liver development delaying the programming of glycogen metabolism.
