Gestational diabetes and maternal obesity are associated with sex-specific changes in miRNA and target gene expression in the fetus.


ABSTRACT: BACKGROUND/OBJECTIVES:Pregnancies complicated by gestational diabetes (GDM) or maternal obesity have been linked to the development of diabetes, obesity, and fatty liver disease later in life with sex-specific manifestations. Alterations in miRNA expression in offspring exposed to GDM and maternal obesity and effects on hepatic development are unknown. Here, we describe how exposure to maternal obesity in utero leads to sex-specific changes in miRNA and target gene expression in human fetal liver. METHODS:Candidate miRNA expression was measured in second trimester amniotic fluid (AF) from women with GDM. Targets of differentially expressed miRNAs were determined and pathway enrichment of target genes was performed. MiRNA and target gene expression were measured in a separate cohort of second trimester primary human fetal hepatocytes (PHFH) exposed to maternal obesity via qPCR and western blot. All studies were IRB approved. RESULTS:GDM-exposed AF had significant increases in miRNAs 199a-3p, 503-5p, and 1268a (fold change (FC)???1.5, p?
