Toxicogenomic responses in sheepshead minnow (Cyprinodon variegatus) exposed to polyethylene terephthalate (PET) microfibers

ABSTRACT: Purpose: To analyze the toxicity effect of sheepshead minnow larvae exposed to PET microfibers through RNA seq. The expression of specific and sensitive genes on PET microfibers was confirmed and verified through qRT-PCR. Method: RNA was isolated from a sample exposed to PET microfibers (concentration of 10, 100 mg/L) for 10 days using a 72 hpf sheepshead minnow larvae. mRNA was produced with a TruSeq Standed mRNA library kit, and sequencing using a NovaSeq6000 equipment. qRT–PCR validation was performed using SYBR Green assays Results and Conclusions: Our study represents a detailed analysis of the transcriptome of sheepshead minnow larvae exposed to PET microfibers by RNA-seq technology. Through the 10 and 100 mg/L PET exposure, 670 differentially expressed genes confirmed. These genes that are specific and sensitive to PET microfibers are concentrated in Dendrite morphogenesis, heart development, intracellular protein kinase cascade, cell migration, and cardiac muscle cell development through GO analysis. In addition, the changes in cancer genesis, cell reaction, energy, and neuronal related genes were confirmed.

Project description:Production, usage and disposal of the munitions constituent (MC) cyclotrimethylenetrinitramine (RDX) has led to environmental releases on military facilities. The chemical attributes of RDX are conducive for leaching to surface water which may put aquatic organisms at risk of exposure. Because RDX has been observed to cause aberrant neuromuscular effects across a wide range of animal phyla, we assessed the effects of RDX on central nervous system (CNS) function in the representative aquatic ecotoxicological model species, fathead minnow (Pimephales promelas). A brain-tissue based cDNA library enriched for transcripts differentially expressed in response to RDX exposure was developed for fathead minnow and was transitioned to custom cDNA-based microarrays. All 4,128 cDNAs were sequenced, quality filtered and assembled yielding 3,018 unique sequences and 945 significant blastx matches (E ≤ 10-5). Bioassays were conducted exposing fathead minnows to RDX at 0.625, 1.25, 2.5, 5, 10 mg/L or an acetone-spike control for 10d. Overt toxicity of RDX in fathead minnow occurred only at the highest exposure concentration resulting in 50% mortality. Conversely, Bayesian analysis of microarray data indicated significant changes in transcript expression in fathead minnow brain tissue at RDX concentrations as low as 0.625 mg/L. In total, 154 microarray targets representing 44 unique transcript identities were differentially expressed in RDX exposures, the majority of which were validated by RT-qPCR. Investigation of molecular pathways, gene ontology and individual gene functions indicated that RDX exposures affected metabolic processes involved in: oxygen transport, neurological function, calcium binding / signaling, energy metabolism, cell cycle / cell proliferation, oxidative stress and ubiquitination. In total, our study indicated that RDX exposure affected molecular processes critical to CNS function in fathead minnow. 10 Day RDX Exposure, Brain Tissue Investigation: Sub-adult fathead minnows were exposed to RDX in a 10d dose-series experiment (0.625, 1.25, 2.5, 5.0, or 10 mg/L RDX) which included an acetone-spike control (1% acetone). Each experimental treatment included 8 replicate fish (48 total fish) and endpoints included mortality, total weight and neurotoxicogenomics. The 1.25mg/L dose was not included in the microarray experiment. Please see attached PDF file for detailed 'Balanced, Interwoven Loop Design'.

Project description:Nanoparticles are compounds of emerging concern with largely unknown risks for human and ecological health. It is crucial to evaluate their potential biological impact to prevent unintended adverse effects on human health and the environment. We analyzed the transcriptional effects of polyvinylpyrrolidone-coated silver nanoparticles (PVP-AgNPs) and silver nitrate (AgNO3) on the fathead minnow (Pimephales promelas) to understand their potential toxicity and adverse outcomes. We also tested the feasibility of the fathead minnow as an alternative species to elucidate potential adverse effects on humans. Fathead minnow females were exposed to either 4 Âµg/L of AgNO3 or 70 Âµg/L of PVP-AgNPs for 96h. Microarray analyses were performed on liver and brain. Functional analysis identified potential toxicity pathways and molecular initiating events (MIEs) that were confirmed with functional assays. Data suggested that AgNO3 and PVP-AgNPs had both common and distinct transcriptional effects. The nanoparticles were linked to neurotoxicity and oxidative stress, and identified as a dopamine receptor antagonist. Silver nitrate was also identified as a potential neurotoxicant and was confirmed as adrenergic and cannabinoid receptors antagonist. While silver nitrate and PVP-AgNPs were both potential neurotoxicants, they appeared to act through different MIEs. Fathead minnow is a promising alternative species to elucidate potential adverse effects of relevance to human health. We analyzed the transcriptional effects of polyvinylpyrrolidone-coated silver nanoparticles (PVP-AgNPs) and silver nitrate (AgNO3) on the fathead minnow (Pimephales promelas) to understand their potential toxicity and adverse outcomes. FHM were obtained from Aquatic Biosystems (Fort Collins, CO), held in aerated dechlorinated tap water and fed three times daily with ZeiglerÂ® AquaTox Feed Gardners, PA, USA). Fathead minnow females were exposed to either 4 Âµg/L of AgNO3 or 70 Âµg/L of PVP-AgNPs (Luna Innovations, Blackburn, VA) for 96h at 24Â°C Â± 1 with a 90% water change at 48 hours. Microarray analyses were performed on liver and brain.

Project description:Zebrafish (Danio rerio) were obtained from the Zebrafish Research Facility maintained in the Center for Environmental Biotechnology at the University of Tennessee. Fish husbandry, spawning, and experimental procedures were conducted with approval from the University of Tennessee Institutional Animal Care and Use Committee (Protocol #1690-1007). Water for holding fish and conducting experiments (hereafter referred to as fish water) consisted of MilliQ water (Millipore, Bedford, MA) with ions added: 19 mg/L NaHCO3, 1 mg/L sea salt (Instant Ocean Synthetic Sea Salt, Mentor, OH), 10 mg/L CaSO4, 10 mg/L MgSO4, 2 mg/L KCl. Embryos were obtained by spawning adult fish with no history of contaminant exposure. Fertilization of embryos took place at the same time (Â± 15 min.), such that larvae used in experiments were of similar age at the time of exposure. All activities (maintenance of adult fish, spawning, and experiments) were conducted in an environmental chamber with a temperature of 27Â± 1 ÂºC and 14:10h light:dark photoperiod. Experiment Overall Design: At 72 h post-fertilization, zebrafish larvae were exposed to lyophilized Microcystis and purified MC-LR at concentrations of 100 and 1,000 Âµg/L. Controls consisted of zebrafish system water (negative control) and zebrafish system water containing 0.05% ethanol (vehicle control). Larvae from both control groups as well as 100 Âµg/L MC-LR, 1,000 Âµg/L MC-LR, and lyophilized Microcystis were exposed in groups of 50 with three replicates and were sacrificed after 96 hours for total RNA extraction and subsequent microarray analysis. All larvae were exposed in beakers containing 100 ml of solution. Experiment Overall Design: Water samples for microcystin analysis and water quality measurements were taken during the experiment, and mortality and behavioral observations were recorded at 24-hour intervals. Microcystin analysis was conducted by protein phosphatase inhibition assay. Measured concentrations of microcystin-LR were 140 Â± 12 SD (low concentration) and 1,703 Â± 71 SD (high concentration). The concentration of microcystin-LR in the lyophilized Microcystis treatment was 4.5 Âµg/L. Water quality parameters measured included dissolved oxygen (6.7 mg/L), pH (6.9), total alkalinity (36 mg/L as CaCO3), total hardness (18 mg/L as CaCO3), and ammonia (<0.2 mg/L). No significant mortality or behavioral changes in larvae were observed during the exposure.
