Protective and sex-specific effects of moderate dose folic acid supplementation on the placenta following assisted reproduction in mice.

ABSTRACT: Epigenetic defects induced by assisted reproductive technologies (ART) have been suggested as a potential mechanism contributing to suboptimal placentation. Here, we hypothesize that ART perturbs DNA methylation (DNAme) and gene expression during early placenta development, leading to abnormal placental phenotypes observed at term. Since folic acid (FA) plays a crucial role in epigenetic regulation, we propose that FA supplementation can rescue ART-induced placental defects. Female mice were placed on a control diet (CD), a moderate 4-fold (FAS4) or high dose 10-fold (FAS10) FA-supplemented diet prior to ART and compared to a natural mating group. ART resulted in 41 and 28 differentially expressed genes (DEGs) in E10.5 female and male placentas, respectively. Many DEGs were implicated in e
