Project description:Transcription profiling of lung and liver from low and high dose Perfluorooctanoic Acid exposed fetuses
2020-04-03 | E-GEOD-13044 | ExpressionAtlas
Project description:Exposure to PFOA during gestation altered the expression of genes related to fatty acid catabolism in both the fetal liver and lung. In the fetal liver, the effects of PFOA were robust and also included genes associated with lipid transport, ketogenesis, glucose metabolism, lipoprotein metabolism, cholesterol biosynthesis, steroid metabolism, bile acid biosynthesis, phospholipid metabolism, retinol metabolism, proteosome activation, and inflammation. These changes are consistent with activation of PPAR alpha. Non-PPAR alpha related changes were suggested as well. Experiment Overall Design: Experiment 1: High Dose: Thirty timed-pregnant CD-1 mice were orally dosed from gestation day 1-17 with either 0, 5, or 10 mg/kg/day PFOA in water. At term, fetal lung and liver were collected, total RNA prepared, and samples pooled from three fetuses per litter. Five biological replicates consisting of individual litter samples were then evaluated for treatment group using Affymetrix mouse 430_2 microarrays. Experiment Overall Design: Experiment 2: Low Dose: Thirty timed-pregnant CD-1 mice were orally dosed from gestation day 1-17 with either 0, 1, or 3 mg/kg/day PFOA in water. At term, fetal lung and liver were collected, total RNA prepared, and samples pooled from three fetuses per litter. Five biological replicates consisting of individual litter samples were then evaluated for treatment group using Affymetrix mouse 430_2 microarrays (note one microarray from the lung + 1mg/kg/day dose group was excluded from the study due to high background). Experiment Overall Design: Please note that each dose experiment had separate concurrent controls.

Project description:Multiple per- and polyfluoroalkyl substances (PFAS) have been associated with adverse liver outcomes in adult humans and toxicological models, but effects on the developing liver or biologic pathways involved are not known. We performed whole-transcriptome gene expression analysis to investigate the molecular mechanisms of liver toxicity in the dam and female fetuses after exposure to two different PFAS, perfluorooctanoic acid (PFOA) and its replacement, hexafluoropropylene oxide-dimer acid (HFPO-DA, commonly referred to as GenX).

Project description:The aim of reprotoxicity testing is to reveal adverse effects of chemicals and drugs on reproduction and on pre and postnatal fetal development. There is very limited data available on gene expression profiling for elucidation of the teratogenic effects of nongenotoxic teratogens. Therefore, research was undertaken to obtain knowledge on the molecular effects of MSC1096199 (previously known as EMD 82571), a calcium sensitizer that was abandoned in the preclinical development phase due to its teratogenic effects in some foetuses. Pregnant wistar rats were dose daily with either MSC1096199 (50 or 150 mg/kg) or Retinoic acid (10 mg/kg) on gestational days 6-17. Microarray experiment were performed using four different tissues (maternal liver, embryo liver (GD20), embryo bone (GD20), and whole embryo (GD12)) under four different conditions (vehicle, low dose and high dose of MSC1096199 and Retinoic acid) to determine the drug regulated genes. In the high dose treatment group, approximately 58% of the fetuses showed malformations i.e. exencephaly and agnathia, and toxicogenomics evidenced that the genes critically involved in osteogenesis, odontogenesis and extra cellular matrix components to be significantly regulated by MSC1096199, therefore providing a molecular rational for the observed teratogenic effects. Pregnant wistar rats were treated daily with the dose of either MSC1096199 (50 or 150 mg/kg) or Retinoic acid (10 mg/kg) on gestational days 6-17. Microarray experiment were performed using four different tissues (maternal liver, embryo liver, embryo bone, and whole embryo) under four different conditions (vehicle, low dose and high dose of MSC1096199 and Retinoic acid) to determine the drug regulated genes.

Project description:Perfluoroalkyl substances (PFAS) are man-made chemicals with suspected endocrine-disrupting properties. Exposure to perfluorooctanoic acid (PFOA) has been linked to disturbed metabolism via the liver, although the exact mechanism is not clear. Moreover, information on the metabolic effects of the new PFAS alternative GenX is limited. We tested whether low-dose exposure to PFOA and GenX induces metabolic disturbances, including NAFLD, dyslipidemia, and glucose tolerance in mice and studied the involvement of PPARα. To this end, male C57BL/6J wildtype and PPARα−/− mice were given 0.05 or 0.3 mg/kg bw/day PFOA, or 0.3 mg/kg bw/day GenX next to a high-fat diet for 20 weeks. RNA sequencing was performed on liver, next to thorough assesment of metabolic parameters. RNA sequencing revealed that whereas the effects of GenX are entirely dependent on PPARα, effects of PFOA are mostly dependent on PPARα. In the absence of PPARα, the involvement of PXR/CAR becomes more prominent. Exposure to high-dose PFOA in mice decreased body weights and increased liver weights in wildtype and PPARα−/− mice. High-dose but not low-dose PFOA reduced plasma triglycerides and cholesterol, which for triglycerides, showed PPARα dependency. PFOA and GenX increased hepatic triglycerides in a PPARα-dependent manner. Overall, we show that long-term and low-dose exposure to PFOA and GenX disrupts lipid metabolism in mice. Whereas the effects of PFOA are mediated by multiple nuclear receptors, effects of GenX are entirely mediated by PPARα. Our data underscore the potential of PFAS to disrupt metabolism by altering signaling pathways in the liver.

Project description:This project utilized oligonucleotide microarrays to examine gene expression patterns in adult male fathead minnows (Pimephales promelas) exposed to a common nanomaterial, titanium dioxide (TiO2, stearate-coated particles, MT-100TV®). We exposed adult male fathead minnows for 96 hr to three doses (0, 1, and 10 mg/L nominal) of TiO2 under static renewal conditions. TiO2 is stearate coated, 15 nm particle size. Three-condition experiment: high dose, controls (untreated, low dose). Three tissues: liver, gill, brain. Biological replicates: 4 control replicates, 4 low dose, 4 high dose for gill and liver. One array for brain control and low dose; and 2 arrays for brain high dose. Contributor: Johnson & Johnson Worldwide Envrionmental
