Project description:Maternal folic acid intake is crucial for the development of the offspring's nervous system, and folic acid metabolism disorders during pregnancy lead to neural tube defects (NTDs) in the fetus. Folic acid and vitamins biosynthesis is a major biochemical feature of gut microbiota. The complex and diverse microbial ecosystem residing within maternal host contributes critically to these intergenerational impacts. However, the mechanisms still require further investigation. In this study, we found that the low folate diets combined MTX-induced changed the structure/composition of the gut microbiota and substantially altered the fecal metabolic phenotype of pregnant mice, including central carbon metabolism in cancer and vitamin digestion & absorption. We demonstrated that the correlation betweent gut microbiota of pregnant mice and the brain metabolic profiles of NTDs fetal mice. According to our data, the Lactobacillales and Bifidobacteriales abundances in pregnant mice gut were positively correlated with the abundances of lipid metabolites in fetal mice brain. The abundances of Enterobacterales and Clostridiales were negatively correlated with those lipid metabolites. Interestingly, the abundance of Inosine, Uridine, L-Carnitine and Glycerophosphocholine were down-regulated synchronously in pregnant feces and NTDs fetal mice brain. This was probably the intergenerational microbial-metabolism biomarkers of NTDs. Our study provides evidence for how perinatal microecological factors shape fetal neural tube development.
