Project description:Genome wide DNA methylation profiling of cord blood cells obtained from normal glucose tolerance (NGT) 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 61 NGT subjects.
Project description:Fetal progenitor endothelial cells (endothelial colony forming cells; ECFC) are recruited for repair, vascular growth and angiogenesis and their high abundance perinatally suggests a function in postnatal vasculogenesis and angiogenesis. In this study we profiled ECFCs from pregnancies of control, overweight and diabetic mothers to study if adverse pregnancies are associated with epigenetic variation in ECFCs.
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:Liver transcriptome profile in subjects with impaired glucose metabolism and steatosis >3 revealed differences compared with subjects with steatosis <1 and normal glucose tolerance. Several well-characterized markers of non-alcoholic fatty liver disease (NAFLD) were identified as differentially expressed between the two groups.
Project description:We performed miRNA profiling of umbilical cord plasma (UCP) to investigate the association of circulating neonatal miRNAs with maternal metabolic parameters and neonatal anthropometric, metabolic, and inflammatory characteristics in healthy pregnancies. We collected data and UCP samples from 16 pregnancies, in equal parts with normal weight and overweight mothers, and male and female neonates. We performed next-generation miRNA sequencing and analysed metabolic and inflammatory parameters in UCP. Our results revealed that the majority of UCP miRNAs are sensitive to maternal and neonatal characteristics, particularly to maternal BMI, Our study highlights the susceptibility of UCP miRNAs to maternal metabolism, demonstrates their association with neonatal metabolic and inflammatory traits, and underscores the potential role of circulating umbilical cord blood miRNAs in fetal metabolism and development.
Project description:In bacteria, antibiotic tolerance, the ability of a susceptible population to survive high doses of cidal drugs, has been shown to compromise therapeutic outcomes. In comparison, whether fungicide tolerance can be induced by host-derived factors during fungal diseases remains unproven. Here, through a systematic evaluation of metabolite-drug-fungal interactions in the leading fungal meningitis pathogen, Cryptococcus neoformans, we found that glucose, on which the brain depends for fuel, induces fungal tolerance to amphotericin B (AmB) in mouse brain tissue and patient cerebrospinal fluid via the fungal glucose repression activator Mig1. To explore the mechanisms underlying glucose-dependent AmB tolerance mediated by Mig1, we used time-series RNA-seq to evaluate dynamic gene expression in wildtype and mig1Δ fungi after exposure to AmB under both drug-tolerant (glucose) or drug-sensitive (galactose) conditions.
