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.

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.

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).

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.

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.

Exosome proteomics reveals the deregulation of coagulation, complement and lipid metabolism proteins in gestational diabetes mellitus

Project description:Exosomes are the smallest extracellular vesicles which are released during pregnancy by the placenta, umbilical cord, amniotic fluid and various cell membranes in the extracellular space. The content of exosomes during pregnancy is strongly related to various conditions such as gestational diabetes mellitus (GDM). Although it is well-known that GDM is characterized by different levels of chronic low-grade inflammation, complement system dysregulation, vascular dysfunction and platelet activation, there is little data characterizing the serum exosomal protein cargo of GDM patients and their associations to these processes. The aim of this study was to analyze the serum exosomal proteome of GDM patients, with focus on the platelet activation and the complement proteins and their relationship to serum biochemical parameters and other protein markers of lipid metabolism and prothrombotic factors.

Identification of the novel function of adipocyte plasma membrane associated protein (APMAP) in gestational diabetes mellitus by proteomic analysis of omental adipose tissues

Project description:Gestational diabetes mellitus (GDM) is considered as the early stage of type 2 diabetes mellitus. In this study, we compared the demographic and clinical data between six GDM and six NGT (healthy controls) and found the HOMA-IR was increased in GDM. Previously, many researches had proved that omental adipose tissues dysfunction could induce insulin resistance. Thus, in order to investigate the cause of the insulin resistance in GDM, label-free proteomics was used to discover differentially expressed proteins in omental adipose tissues between GDM and NGT. A total of 3529 proteins identified, including 66 significantly changed proteins. Adipocyte plasma membrane associated protein (APMAP also called C20orf3) was one of changed proteins and down regulated in GDM omental adipose tissues. Further, mature 3T3-L1 adipocytes were used to simulate omental adipocytes and we found that inhibited the expression of APMAP by RNAi would impaired the insulin signaling and activated the NFkB signaling in adipocytes. These results indicated that the decreased of APMAP in mental adipose tissues may be important in process of the insulin resistance in GDM.
