Genome wide methylation of cord blood from gestational diabetes mellitus

Project description:Genome wide DNA methylation profiling of cord blood cells obtained from gestational diabetes mellitus (GDM) pregnancies. The Illumina EPIC methylation beadchip array was used to obtain DNA methylation profiles across approximately 850,000 CpG dinucleotide methylation loci in DNA isolated from cord blood. Samples include 165 GDM subjects.

Single-cell RNA-sequencing of umbilical cord blood reveals impaired fetal immune homeostasis by gestational diabetes mellitus

Project description:Gestational diabetes mellitus (GDM), the most prevalent metabolic disorder during pregnancy, has long-term risks of metabolic diseases that might persist in adulthood. However, the underlying mechanisms remain unclear. Here, we profiled 78,767 cord blood mononuclear cells (CBMCs) from GDM and healthy mothers’ fetuses by single-cell RNA sequencing (scRNA-seq).

Reduced representation bisulfite sequencing (RRBS) methylation profiles of placenta and umbilical cord blood with or without gestational diabetes mellitus (GDM)

Project description:Objective: To explore the characteristics and underlying molecular mechanisms of genome-scale expression profiles of women with- or without- gestational diabetes mellitus and their offspring. Materials and Methods: We recruited a group of 21 pregnant women with gestational diabetes mellitus (GDM) and 20 healthy pregnant women as controls. For each pregnant women, RRBS were performed using the placenta and paired neonatal umbilical cord blood specimens. Differentially methylated regions (DMRs) were identified. Then, functional enrichment analysis was performed to differential methylated genes (DMGs) separately or interactively in placenta and umbilical cord blood. Results: Through the comparison of GDM and healthy samples, 2779 and 141 DMRs were identified from placenta and umbilical cord blood, respectively. Functional enrichment analysis showed that the placenta methylation and expression profiles of GDM women mirrored the molecular characteristics of “type II diabetes” and “insulin resistance”. Methylation-altered genes in umbilical cord blood were associated with pathways “type II diabetes” and “cholesterol metabolism”. DMGs illustrated significant overlaps among placenta and umbilical cord blood samples, and the overlapping DMGs were associated with cholesterol metabolism. Conclusions: Our research demonstrated the epigenomic alternations of GDM mothers and offspring. Our findings emphasized the importance of epigenetic modifications in the communication between pregnant women with GDM and offspring, and provided reference for the prevention, control, treatment, and intervention of perinatal deleterious events of GDM and neonatal complications.

Exosomal RNA expression profiles and their prediction performance in gestational diabetes mellitus patients with macrosomia

Project description:Exosomal RNAs in cord blood may allow intercellular communication between maternal and fetus. We aimed to establish exosomal RNA expression profiles in cord blood exosomes from gestational diabetes mellitus (GDM) patients with macrosomia.We used microarray technology to establish the differential mRNA, lncRNA and circRNA expression profiles in cord blood exosomes from GDM patients with macrosomia compared with normal controls. A total of 98 mRNAs, 372 lncRNAs and 452 circRNAs were differentially expressed in cord blood exosomes from GDM patients with macrosomia. Pathway analysis showed the differential genes were associated with PI3K-Akt signaling pathway, JAK-STAT signaling pathway, TGF-beta signaling pathway, insulin resistance, glycerolipid metabolism, fatty acid degradation and mTOR signaling pathway. These results showed that exosomal RNAs are aberrantly expressed in the cord blood of GDM patients with macrosomia.
