摘要
The onset of complex diseases at a later stage of life has been linked with maternal folic acid (FA) ingestion. However, little is known regarding the underlying molecular fingerprints of the offspring. We integrated proteomics-metabolomics profiles and analyzed the influence of maternal FA supplementation on the metabolism of adult offspring rats. Twenty pregnant female rats were randomly assigned to a FA supplementation (FolS group, 10 mg/kg FA) or control group (2 mg/kg FA respectively). Such an omics approach revealed that the dopaminergic synapse pathway, tricarboxylic acid cycle and neural development-related metabolites such as glutamic acid and gamma-aminobutyric acid were significantly up-regulated in the FolS group, whereas pyruvic acid, oxalic acid and adipic acid were reduced. Maternal FA supplementation can cause alterations of metabolites and protein in the offspring rats.
