#METABOLOMICS WORKBENCH jwalejko_20200818_081055 DATATRACK_ID:2123 STUDY_ID:ST001448 ANALYSIS_ID:AN002419 PROJECT_ID:PR000995 VERSION 1 CREATED_ON August 20, 2020, 11:40 am #PROJECT PR:PROJECT_TITLE Maternal Hypercortisolemia alters placental metabolism PR:PROJECT_SUMMARY Previous studies have suggested that increases in maternal cortisol or maternal PR:PROJECT_SUMMARY stress in late pregnancy increase the risk of stillbirth at term. In an ovine PR:PROJECT_SUMMARY model with increased maternal cortisol over the last 0.20 of gestation, we have PR:PROJECT_SUMMARY previously found evidence of disruption of fetal serum and cardiac metabolomics, PR:PROJECT_SUMMARY and altered expression of genes related to mitochondrial function and metabolism PR:PROJECT_SUMMARY in biceps femoris, diaphragm and cardiac muscle. The present studies were PR:PROJECT_SUMMARY designed to test for effects of chronically increased maternal cortisol on gene PR:PROJECT_SUMMARY expression and metabolomics in placentomes near term. We hypothesized that PR:PROJECT_SUMMARY changes in placenta may underlie or contribute to the alterations in fetal serum PR:PROJECT_SUMMARY metabolomics, and thereby contribute to changes in striated muscle metabolism. PR:PROJECT_SUMMARY Placentomes were collected from pregnancies in early labor (143±1 d gestation) PR:PROJECT_SUMMARY of control ewes (n=7) or ewes treated with cortisol (1 mg/kg/d iv; n=5) starting PR:PROJECT_SUMMARY at day 115 of gestation. Transcriptomics and metabolomics were performed using PR:PROJECT_SUMMARY an ovine gene expression microarray (Agilent 019921) and HR-MAS NMR, PR:PROJECT_SUMMARY respectively. Multi-omic analysis indicates that amino acid metabolism, PR:PROJECT_SUMMARY particularly of branched chain amino acids and glutamate occur in placenta; PR:PROJECT_SUMMARY changes in amino acid metabolism, degradation or biosynthesis in placenta were PR:PROJECT_SUMMARY consistent with changes in valine, isoleucine, leucine and glycine in fetal PR:PROJECT_SUMMARY serum. The analysis also indicates changes in glycerophospholipid metabolism and PR:PROJECT_SUMMARY suggests changes in ER stress and antioxidant status in the placenta. These PR:PROJECT_SUMMARY findings suggest that changes in placental function occurring with excess PR:PROJECT_SUMMARY maternal cortisol in late gestation may contribute to metabolic dysfunction at PR:PROJECT_SUMMARY birth.

CORT ewes received an intravenous infusion of cortisol (Solu-Cortef, CO:COLLECTION_SUMMARY hydrocortisone sodium succinate in sodium phosphate; Pfizer, New York, NY); CO:COLLECTION_SUMMARY control animals did not receive any treatment. Animals were sacrificed for CO:COLLECTION_SUMMARY collection of tissues at the first signs of labor, as evidenced by changes in CO:COLLECTION_SUMMARY uterine blood flow; placentomes were collected from sheep in early stages of CO:COLLECTION_SUMMARY labor at between 141-144 days and 142-144 days of gestation in the CO:COLLECTION_SUMMARY cortisol-treated and control groups, respectively. In this cohort of ewes, there CO:COLLECTION_SUMMARY were 7 control ewes, of which data were collected from placentomes of 7 live CO:COLLECTION_SUMMARY fetuses (including one set of twins); there was one lamb born, and that placenta CO:COLLECTION_SUMMARY was not collected. In this cohort there were 11 cortisol- treated ewes, from CO:COLLECTION_SUMMARY which we collected placentomes from 5 live fetuses. There was one live lamb CO:COLLECTION_SUMMARY born, and 5 stillborn lambs, from which placentas were not collected. CO:COLLECTION_SUMMARY Placentomes were classified as A-D placentomes, snap frozen in liquid nitrogen, CO:COLLECTION_SUMMARY and stored in -80C until metabolomic analysis. CO:SAMPLE_TYPE Placenta #TREATMENT TR:TREATMENT_SUMMARY Placentomes were collected at necropsy from control ewes and ewes treated with TR:TREATMENT_SUMMARY cortisol (CORT: 1mg/kg/d from day 115 of pregnancy) at days 141-144 of TR:TREATMENT_SUMMARY gestation. CORT ewes received an intravenous infusion of cortisol (Solu-Cortef, TR:TREATMENT_SUMMARY hydrocortisone sodium succinate in sodium phosphate; Pfizer, New York, NY); TR:TREATMENT_SUMMARY control animals did not receive any treatment. #SAMPLEPREP SP:SAMPLEPREP_SUMMARY High-resolution magic angle spinning (HR-MAS) proton nuclear magnetic resonance SP:SAMPLEPREP_SUMMARY (1H-NMR) was used to determine metabolites present in placental tissue. Briefly, SP:SAMPLEPREP_SUMMARY 30 μL of deuterium oxide (D2O) with 3.3 mM 3-(Trimethylsilyl)-1-propanesulfonic SP:SAMPLEPREP_SUMMARY acid (DSS) as a reference standard was added to 27.7-52.1 mg (mean 35.3 mg) of SP:SAMPLEPREP_SUMMARY placental tissue before being placed into a 4 mm HR-MAS rotor (Bruker Biospin) SP:SAMPLEPREP_SUMMARY and spun at 6 kHz with a spectral width of 10 ppm. Data were acquired on an SP:SAMPLEPREP_SUMMARY Avance III 600 MHz Bruker NMR spectrometer equipped with a 4 mm HR-MAS probe at SP:SAMPLEPREP_SUMMARY the University of Georgia Complex Carbohydrate Research Center. Data were SP:SAMPLEPREP_SUMMARY acquired using a one-dimensional experiment with T2 filter using SP:SAMPLEPREP_SUMMARY Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence with water presaturation
