Heatmap of False Discovery Prices (FDRs) of top rated metabolic pathway hits amongst all comparison groups. Filtering criterion was 1) genes and metabolites metabolites with FDR of 0.1 of less as well as a minimum 2-fold alter in a minimum of 1 comparison group between CVP and CVNP, GFP and GFP, GFNP and CVNP, and GFP and CVP mice; and 2) a minimum of 1 gene and 1 metabolite hit per pathway with FDR 0.1 and a minimum 2-fold adjust inside the comparison groups involving CVP and CVNP, GFP and GFP, GFNP and CVNP, and GFP and CVP mice. Those that failed to meet this criterion was labeled as P = 1. CVNP, standard non-pregnant mice; CVP, standard pregnant mice; GFNP, germ-free non-pregnant mice; GFP, germ-free pregnant mice. https://doi.org/10.1371/journal.pone.0248351.gacid metabolism, retinol metabolism, arachidonic acid metabolism, and steroid hormone biosynthesis are shown in S1 4 Figs, respectively.DiscussionPregnancy imposes substantial adaptive metabolic adjustments to the mother to retain the wellbeing of herself and her fetus [19, 20]. Current studies have extensively discussed the potential for the gut microbiome to modulate host metabolism of endogenous and exogenous substances [5]. Quite little is known about how the microbiome alters host metabolic processes in the course of pregnancy. Thus, in this study, we explored modifications within metabolic pathways connected towards the microbiome in pregnancy applying CV and GF pregnant mouse models. We made use of an method that integrated changes in both hepatic gene expression and maternal plasma metabolites. Overall, we observed similar adjustments in metabolic pathways associated with pregnancy in CV and GF mice, with 8 metabolic pathways for endogenous compounds Syk drug enriched for DEGs related with all the pregnancy status in each groups, and only 1 pathway (Drug metabolism by cytochrome P450) was uniquely enriched for DEGs linked with pregnancy in GF.
