Downregulations of placental fatty acid transporters during cadmium-induced fetal growth restriction.

•The FGR in Cd-treated mice is linked to the decreased placental TG level and the decreased expression levels of FATP1, FATP6 and FABP3.•The FGR in Cd-treated mice is not associated with the maternal supply.•The decreased expression levels of FATP1, FATP6 and FABP3 is associated with the p38-MAPK, p38 MAPK/PPAR-γ and HIF-1α pathways respectively.•The differential expression levels of FATP1, FATP6 and FABP3 were not correlated with the DNA methylation modification of the promoter regions.
