RNA sequence of gestational diabetes mellitus (GDM) and healthy control placentas

Project description:GDM is a multi-system disorder that is primarily characterised by new-onset hypertension accompanied by proteinuria during gestation. This disease is one of the leading causes of maternal and perinatal morbidity and mortality. In this work, placental samples were collected from GDM and control patients. RNA-seq was performed to identify differences in gene expression. Significantly differentially expressed genes between the GDM and control samples included 64 up-regulated and 296 down-regulated genes. This study may provide further insight in the mechanisms of GDM and function as preventive, predictive and therapeutic measures.

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.

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.

Integrated analysis of the transcriptome-wide m6A methylome in gestational diabetes mellitus and healthy control placentas [meRIP-seq]

Project description:N6-methyladenosine (m6A) is the most prevalent modification in eukaryotic mRNA and potential regulatory functions of m6A have been shown by mapping the RNA m6A modification landscape. M6A modification in active gene regulation manifests itself as altered methylation profiles. However, the profiling of m6A modification and its potential role in gestational diabetes mellitus (GDM) has not yet been studied. In this work, placental samples were collected from GDM and control patients. MeRIP-seq was performed to identify differences in m6A methylation. Fragmented mRNAs were incubated for 2 h at 4 °C in the presence of 2 μg m6A antibodies (Synaptic Systems, 202003) in a 500 μl IP reaction system, and some of the fragments were used as input. RNA-seq libraries for m6A antibody-enriched mRNAs and input mRNAs were prepared using the KAPA Stranded mRNA-seq Kit (Illumina, CA, USA). Altered peaks of m6A-modified transcripts were primarily associated with mTOR signaling pathway, Notch signaling pathway, TGF-beta signaling pathway and so on. Our data provide novel information regarding m6A modification alterations in GDM and help our understanding of the pathogenesis of GDM.

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).

Plasma exosomal microRNAs associated with metabolism as early predictor of gestational diabetes mellitus

Project description:The microRNA (miRNA) expression profile of plasma exosome in pregnant women complicated with gestational diabetes mellitus (GDM) has not been fully clarified. In this study, differentially expressed miRNAs in plasma exosomes were identified by high-throughput small RNA sequencing in 12 GDM and 12 normal glucose tolerance (NGT) pregnant women and validated in 102 GDM and 101 NGT pregnant women. A total of 22 exosomal miRNAs were found and five of them were verified by qRT-PCR. Exosomal miR-423-5p was upregulated, while miR-99a-5p, miR-192-5p, miR-148a-3p, and miR-122-5p were downregulated in pregnant women complicated with GDM.

DIA proteomics for gestational diabetes mellitus

Project description:Gestational diabetes mellitus (GDM), one of the most common pregnancy complications, affects approximately 6% of pregnancies. This study attempted to use the data-independent acquisition (DIA) mass spectrometry (MS) to identify the potential protein biomarkers from the placental tissues from the GDM patients and the normal pregnant women.
