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.

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 adversely affects pancreatic islet development and function in the rat offspring

Project description:Gestational diabetes mellitus (GDM) exposure and obesity are strong risk factors for type 2 diabetes development; however, the connections between GDM exposure, postnatal diet and islet dysfunction in offspring metabolic health remain unclear. Reduced glucose-stimulated insulin secretion was observed in islets isolated from 15-week-old offspring prenatally exposed to GDM, which was exacerbated by postnatal HFS consumption. In the HFS-fed offspring of Lean dams, islet size and number increased, an adaptation that was not observed in the HFS-fed offspring of GDM dams. Islets from GDM exposed offspring revealed upregulation of 102 genes (e.g. Sod2, Il1b) and 13 downregulated genes. In the GDM offspring that consumed a postnatal HFS-diet, 126 genes were significantly upregulated (e.g. Ccl2, Rps14, Atp5f1) and 17 genes were downregulated (e.g. Hnf1a, Slc2a2). These results demonstrate that GDM exposure induced changes in gene expression in the young adult rat offspring that worsen islet function and whole-body glucose homeostasis.

Gestational chronodisruption throughout pregnancy impairs adipose tissue physiology in the offspring

Project description:Compelling evidence supports that gestational chronodisruption induces major changes in maternal circadian rhythms, fetal development and that these changes impact adult life at many physiological levels. Using a rat model of chronic photoperiod shifting throughout gestation (CPS), we investigated the detrimental effects of gestational CPS on glucose homeostasis, adipose tissue physiology and metabolism in the adult male offspring. At proteomic level, in CPS adipose tissue, 275 proteins displayed differential expression, compared with LD animals fed with a standard diet. Interestingly, CPS offspring and LD fed with HFD showed 20 proteins in common (2 upregulated 18 downregulated). Based on these common proteins, the IPA analysis found that 2 functional pathways were significantly altered; the network 1 (AKT/ERK) and the network 2 (TNF/IL4).
