Project description:Circular RNA can regulate blood glucose levels by targeting mRNA expression, but the role of circRNA in GDM is still unknown. Therefore, a joint microarray analysis of circRNAs and their targeting mRNAs using the peripheral blood of GDM patients and healthy pregnant women was carried out for the first time. In our study, high-throughput microarray sequencing technique was used to analyze the expression profile of circRNA and transcripts mRNA in the peripheral blood of GDM patients, in order to comprehensively evaluate the role of circRNAs targets and their parents genes in the signal pathways related to the pathogenesis of GDM. Some of the discovered circRNAs and their linear transcript mRNAs related to T cell receptor signaling pathway were further verified in larger samples by droplet digital PCR(ddPCR) and quantitative real-time PCR(qRT-PCR), respectively. The verification results confirmed the initial microarray results.
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.
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.
Project description:The aim of this study was to establish the exosomal miRNA profile across gestation in normal and GDM pregnancies and to determine the signaling pathways associated with the changes in the miRNA profile in GDM.
Project description:We have reported differntial abundance of miRNAs present in the secretory Extracellular vesicles during Gestetional Diabetes Mellitus or Ischemic placental disease
Project description:tsRNA profiles of gestational diabetes mellitus and healthy control groups were generated by deep sequencing using Illumina NextSeq 500.
Project description:Pancreatic β-cell function impairment is a key mechanism for developing gestational diabetes mellitus (GDM). Maternal and placental exosomes regulate maternal and placental responses during hyperglycemia. Studies have associated exosomal micro RNAs (miRNAs) with GDM development. To date, no studies have been reported that evaluate the profile of miRNAs present in maternal and placental exosomes in the early stages of gestation from pregnancies that develop GDM. We used microarrays to assess whether early pregnancy maternal and placental exosomal miRNA profiles vary according to pancreatic β-cell function in women who will develop GDM (preGDM).
