Abstract
Background/Objective 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 2nd 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
2nd 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<0.05). Female offspring
specific analysis showed enrichment in miRNAs 378a-3p, 885-5p, and 7-1-3p
(p<0.05). MiRNA gene targets were enriched in hepatic pathways. Key
genes regulating de novo lipogenesis were upregulated in
obesity exposed PHFH, especially in males. Significantly altered miRNAs in
GDM AF were measured in obese exposed PHFH, with consistent increases in
miRNAs 885-5p, 199-3p, 503-5p, 1268a and 7-1-3p (FC ≥1.5,
p<0.05). Female PHFH exposed to maternal obesity had increased
expression of miR-885-5p, miR-199-3p, miR-503-5p, miR-1268s and miR-7-1-3p,
(p<0.05), corresponding to decreased target genes expression for
ABCA1, PAK4 and INSR.
In male PHFHs, no miRNA changes were measured but there was increased
expression of ABCA1, PAK4, and
INSR (p<0.05). Conclusion Our data suggest sex-specific changes in miRNA and gene expression in
PHFH may be one mechanism contributing to the sexual dimorphism of metabolic
disease in offspring exposed to GDM and maternal obesity in
utero.

Diabetes in Pregnancy and MicroRNAs: Promises and Limitations in Their Clinical Application. Noncoding RNA 2018; 4:ncrna4040032. [PMID: 30424584 PMCID: PMC6316501 DOI: 10.3390/ncrna4040032] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2018] [Revised: 10/29/2018] [Accepted: 11/05/2018] [Indexed: 12/12/2022] Open
Abstract
Maternal diabetes is associated with an increased risk of complications for the mother and her offspring. The latter have an increased risk of foetal macrosomia, hypoglycaemia, respiratory distress syndrome, preterm delivery, malformations and mortality but also of life-long development of obesity and diabetes. Epigenetics have been proposed as an explanation for this long-term risk, and microRNAs (miRNAs) may play a role, both in short- and long-term outcomes. Gestation is associated with increasing maternal insulin resistance, as well as β-cell expansion, to account for the increased insulin needs and studies performed in pregnant rats support a role of miRNAs in this expansion. Furthermore, several miRNAs are involved in pancreatic embryonic development. On the other hand, maternal diabetes is associated with changes in miRNA both in maternal and in foetal tissues. This review aims to summarise the existing knowledge on miRNAs in gestational and pre-gestational diabetes, both as diagnostic biomarkers and as mechanistic players, in the development of gestational diabetes itself and also of short- and long-term complications for the mother and her offspring.

Abstract
Large birthweight, or macrosomia, is one of the commonest complications for pregnancies affected by diabetes. As macrosomia is associated with an increased risk of a number of adverse outcomes for both the mother and offspring, accurate antenatal prediction of fetal macrosomia could be beneficial in guiding appropriate models of care and interventions that may avoid or reduce these associated risks. However, current prediction strategies which include physical examination and ultrasound assessment, are imprecise. Biomarkers are proving useful in various specialties and may offer a new avenue for improved prediction of macrosomia. Prime biomarker candidates in pregnancies with diabetes include maternal glycaemic markers (glucose, 1,5-anhydroglucitol, glycosylated hemoglobin) and hormones proposed implicated in placental nutrient transfer (adiponectin and insulin-like growth factor-1). There is some support for an association of these biomarkers with birthweight and/or macrosomia, although current evidence in this emerging field is still limited. Thus, although biomarkers hold promise, further investigation is needed to elucidate the potential clinical utility of biomarkers for macrosomia prediction for pregnancies affected by diabetes.

Abstract
Several studies showed that altered expression of the miRNA-ome in maternal circulation or in placental tissue may reflect not only gestational disorders, such as preeclampsia, spontaneous abortion, preterm birth, low birth weight, or macrosomia, but also prenatal exposure to environmental pollutants. Generally, the relationships between environmental exposure, changes in miRNA expression, and gestational disorders are explored separately, producing conflicting findings. However, validation of tissue-accessible biomarkers for the monitoring of adverse pregnancy outcomes needs a systematic methodological approach that takes also into account early-life environmental exposure. To achieve this goal, exposure to xenochemicals, endogenous agents, and diet should be assessed. This study has the aim to provide a comprehensive review on the role of miRNAs as potential biomarkers for adverse pregnancy outcomes and prenatal environmental exposure.

The role, mechanism and potentially novel biomarker of microRNA-17-92 cluster in macrosomia. Sci Rep 2015; 5:17212. [PMID: 26598317 PMCID: PMC4657041 DOI: 10.1038/srep17212] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2015] [Accepted: 10/26/2015] [Indexed: 12/16/2022] Open
Abstract
Macrosomia is one of the most common perinatal complications of pregnancy and has life-long health implications for the infant. microRNAs (miRNAs) have been identified to regulate placental development, yet the role of miRNAs in macrosomia remains poorly understood. Here we investigated the role of miR-17-92 cluster in macrosomia. The expression levels of five miRNAs in miR-17-92 cluster were significantly elevated in placentas of macrosomia, which may due to the up-regulation of miRNA-processing enzyme Drosha and Dicer. Cell cycle pathway was identified to be the most relevant pathways regulated by miR-17-92 cluster miRNAs. Importantly, miR-17-92 cluster increased proliferation, attenuated cell apoptosis and accelerated cells entering S phase by targeting SMAD4 and RB1 in HTR8/SVneo cells. Furthermore, we found that expression of miR-17-92 cluster in serum had a high diagnostic sensitivity and specificity for macrosomia (AUC: 80.53%; sensitivity: 82.61%; specificity: 69.57%). Our results suggested that miR-17-92 cluster contribute to macrosomia development by targeting regulators of cell cycle pathway. Our findings not only provide a novel insight into the molecular mechanisms of macrosomia, but also the clinical value of miR-17-92 cluster as a predictive biomarker for macrosomia.
