Gestational diabetes and human amniocytes

Project description:Context: Context: Gestational diabetes (GDM) has profound effects on the intrauterine metabolic milieu and is linked to obesity and diabetes in offspring, but the mechanisms driving these effects remain largely unknown. Alterations gene expression in amniocytes exposed to GDM in utero may identify potential mechanisms leading to metabolic dysfunction later in life. Objective: Objective: To profile changes in the transcriptome in human amniocytes exposed to GDM Methods: A nested case-control study was performed in second trimeseter amniocytes matched for offspring sex, maternal race/ethnicity, maternal age, gestational age at amniocentesis, gestational age at birth and gestational diabetes status. Sex-specific RNA-sequencing was completed and gene expression changes were identified. Results: Expression of interferon-stimulated genes was increased in GDM amniocytes accounting for 6 of the top 10 altered genes (q<0.05). Enriched biological pathways in GDM anmiocytes included pathways involving inflammation, the interferon response, fatty liver disease, monogenic diabetes and atherosclerosis. Conclusion: In a unique repository of human amniocytes exposed to GDM in utero, trancriptome analysis identified enrichment of inflammation and interferon-related pathways.

Gestational diabetes in mice induces hematopoietic memory that impacts the long-term health of the offspring.

Project description:Gestational diabetes is a common medical complication of pregnancy that is associated with adverse perinatal outcomes and an increased risk of metabolic diseases and atherosclerosis in adult offspring. The mechanisms responsible for this delayed pathological transmission remain unknown. In mouse models, we found that the development of atherosclerosis in adult offspring born to diabetic pregnancy can be in part linked to hematopoietic alterations. Although they do not show any gross metabolic disruptions, the adult offspring maintain hematopoietic features associated with diabetes, indicating the acquisition of a lasting diabetic hematopoietic memory. We show that the induction of this hematopoietic memory during gestation relies on the activity of the pattern recognition receptor AGER and the NLRP3 inflammasome, which leads to increased placental inflammation. In adult offspring, we find that this memory is associated with DNMT1 upregulation and epigenetic changes in hematopoietic progenitors. Altogether, our results demonstrate that the hematopoietic system can acquire a lasting memory of gestational diabetes, and that this memory constitutes a new pathway connecting gestational health to adult pathologies.

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.
