Project description:Transcriptional profiling of log and stationary phases of S. Typhimurium, comparing untreated controls with cortisol-treated samples. Each array used labelled cDNA against a common genomic DNA reference. Triplicate arrays were carried out for each of the 4 conditions: untreated log phase, untreated stationary phase, cortisol treated log phase and cortisol treated stationary phase.

Project description:Chronic early life stress increases adult susceptibility to numerous health problems linked to chronic inflammation. One way that this may occur is via glucocorticoid-induced developmental programming. To gain insight into such programming we treated zebrafish embryos with 1 micromolar cortisol and examined the effects on larvae. Treated larvae had elevated whole-body cortisol and glucocorticoid signaling, and up-regulated genes associated with defense response and immune system processes. 6 samples total were analyzed. 3 DMSO controls, and 3 cortisol treated (1 micromolar).

Project description:We have previously shown in sheep that 10 days of modest chronic increase in maternal cortisol result in fetal heart enlargement and Purkinje cell apoptosis. In subsequent studies in which we extended the duration of cortisol infusion (1mg/kg/d) to term, we found a dramatic incidence of stillbirth in the pregnancies with chronically increased cortisol and associated maternal hyperglycemia. To investigate the effects on the heart, transcriptomic analyses were performed on the septa using ovine microarrays and Webgestalt and Cytoscape programs for pathway inference. Analyses of the effects of 10 days of maternal cortisol infusion (130d-cortisol vs 130d control), ~25 days (term at ~140d-cortisol vs 140d control), normal maturation (140d-control vs 130d control) were performed. In all analyses gene ontology (GO) terms related to immune function and cytokine actions were significantly over-represented. After 10 days of cortisol, growth factor and muscle cell apoptosis pathways were significantly over-represented, consistent with our previous findings. We found significantly differentially regulated genes in the term fetuses (ie after ~25 days of cortisol) in pathways consistent with altered metabolism in the heart, particularly in mitochondria, associated with responses to hypoxia and to nutrient. Analysis of mitochondrial number by quantitative real-time PCR confirmed a significant decrease. These pathways were different from those modeled following the normal increase in cortisol in late gestation which contributes to normal maturation of the heart, and thus may be indicative of the fetal heart pathophysiologies seen in pregnancies complicated by diabetes, Cushing’s disease and chronic stress.

The first cohort received maternal cortisol infusion of 1mg/kg/day or vehicle for 10 days until approximately day 130 of gestation (n=6/group), the second cohort received the same dose of cortisol for approximately 25 days until near term (n=7, cortisol; n=7ewes, n=8 fetuses due to one set of twins, control)

Project description:Previous studies have suggested that increases in maternal cortisol or maternal stress in late pregnancy increase the risk of stillbirth at term. In an ovine model with increased maternal cortisol over the last 0.20 of gestation, we have previously found evidence of disruption of fetal serum and cardiac metabolomics, and of expression of genes related to mitochondrial function and metabolism in biceps femoris, diaphragm and cardiac muscle. The present studies were designed to test for effects of chronically increased maternal cortisol on gene expression and metabolomics in placentomes near term. We hypothesized that changes in placenta may underlie or contribute to the alterations in fetal serum metabolomics, and thereby contribute to changes in striated muscle metabolism. Multi-omic analysis indicates that amino acid metabolism, particularly of branched chain amino acids and glutamate occur in placenta; changes in amino acid metabolism, degradation or biosynthesis in placenta were consistent changes in valine, isoleucine, leucine and glycine in fetal serum. The analysis also indicates changes in glycerophospholipid metabolism, and suggests changes in ER stress and antioxidant status in the placenta. These findings suggest that changes in placental function occurring with excess maternal cortisol in late gestation may contribute to metabolic dysfunction in the fetus at birth.

Project description:Glucocorticoids act through the glucocorticoid receptor (GR), a ligand activated transcription factor, to modulate gene expression profiles in target cells and tissues. The principal physiological glucocorticoid in humans, cortisol, is released in a pulsatile fashion from the adrenal gland, which results in oscillations in blood concentrations, with a period of 1 - 2 hours. The biological consequence of fluctuating cortisol concentrations has not been explored. To identify the role of cortisol concentration oscillations for target cell response a flow-through cell culture system was developed. Transcription profiling was performed in the absence and presence of cortisol. Cells were exposed to constant cortisol levels of 100ng/ml or 200 ng/ml or oscillating cortisol concentrations.

Project description:We have previously shown in sheep that 10 days of modest chronic increase in maternal cortisol result in fetal heart enlargement and Purkinje cell apoptosis. In subsequent studies in which we extended the duration of cortisol infusion (1mg/kg/d) to term, we found a dramatic incidence of stillbirth in the pregnancies with chronically increased cortisol and associated maternal hyperglycemia. In previous studies of the intraventricular septum from these fetuses we found significantly differentially regulated genes in the term fetuses (ie after ~25 days of cortisol) in pathways consistent with altered metabolism in the heart, particularly in mitochondria, associated with responses to hypoxia and to nutrient. Analysis of mitochondrial number by quantitative real-time PCR confirmed a significant decrease. We extended this investigation to the left ventricular free wall of these fetuses.le. Fewer genes were differentially regulated in left ventricle in the near term fetuses. In the LV of this cohort of fetuses, the nonredundant KEGG pathways represented by the DEG were insulin resistance and adipocytokine signaling pathway. GSEA analysis of the DEG in LV identified metabolic pathways as the nonredundant pathway altered. Comparison of the change in gene expression in biceps to that in cardiac intraventricular septum and left ventricle showed few common genes with little overlap in specific metabolic or signaling pathways, despite effects on mitochondria and metabolism in both heart and biceps. Our results suggest that glucocorticoid exposure affects nuclear genes important to mitochondrial activity and reactive oxygen in both cardiac and skeletal muscle tissues in a tissue specific manner.
