Effects of environmentally relevant concentrations of tris (2-butoxyethyl) phosphate on growth and transcription of genes involved in the GH/IGF and HPT axes in zebrafish (Danio rerio). CHEMOSPHERE 2018; 212:376-384.

Abstract
Tris (2-butoxyethyl) phosphate (TBOEP), as one of the most widely used organophosphate flame retardants (OPFRs), is applied in nearly all manufactured items and materials. It has been reported that TBOEP could cause developmental impairments and disrupt the endocrine regulation of fish growth during acute toxic experiments. However, concentrations to which fish were exposed in these studies were greater than environmentally relevant concentrations ever reported. This study examined effects on growth associated with exposure of zebrafish to 0, 0.1, 1 and 10 μg/L TBOEP during 20-90 days post fertilization (dpf). The changes in growth indicators and bioaccumulation of TBOEP were examined along with the transcription of related genes in the growth hormone/insulin-like growth factor (GH/IGF) axis and the hypothalamic-pituitary-thyroid (HPT) axis. The average body contents of TBOEP were higher in females than in males in all the exposure groups. Exposure to environmentally relevant concentrations of TBOEP significantly decreased body length and body mass and down-regulated expression of several genes involved in the GH/IGF and HPT axes. Exposure to TBOEP decreased plasma thyroxine (T4) content accompanied by decreased mRNA level of thyrotropin β-subunit (tshβ) in females at 60 dpf, but no effects were observed at 90 dpf. These results suggested that bioaccumulation of TBOEP and down-regulation of genes involved in the GH/IGF axis might be responsible for the observed growth inhibition in zebrafish exposed to TBOEP.

Abstract
Despite increasing use of organophosphorus flame retardants (OPFRs), their food web transfer behavior is not well known. In this study, concentrations of fourteen OPFRs were measured in 17 species from Taihu Lake, China, and their trophodynamics were assessed. Of the 14 OPFRs, nine were detected in at least 70% of the food web samples, including tris(ethyl) phosphate (TEP), tris(2-chloroethyl) phosphate (TCEP), tris(2-chloroisopropyl) phosphate (TCIPP), tris(isobutyl) phosphate (TIBP), tris(1,3-dichloroisopropyl) phosphate (TDCIPP), tris(n-butyl) phosphate (TNBP), tris(phenyl) phosphate (TPHP), tris(methylphenyl) phosphate (TMPP), and 2-ethylhexyl diphenyl phosphate (EHDPP). The total OPFR concentrations were 100 ± 23 ng/g ww in plankton, 17 ± 11 ng/g ww in invertebrates, and 9.8 ± 6.2 ng/g ww in fish. TIBP (93 ± 16 ng/g ww) was the dominant OPFR in plankton, whereas TCEP (2.4 ± 3.9 ng/g ww) and TPHP (3.3 ± 16 ng/g ww) were dominant in fish. While negative relationships between concentration and aquatic species trophic level were observed for all nine OPFRs, only those for TCIPP (p = 0.022), TDCIPP (p = 0.029), and TMPP (p = 0.021) were statistically significant, with trophic magnification factors (TMFs) of 0.55, 0.39, and 0.42, respectively. This study provides fundamental information for assessing ecological risks of OPFRs.

Comp Biochem Physiol C Toxicol Pharmacol 2018; 212:34-46.

Abstract
Zebrafish has become a popular model organism in several lines of biological research sharing physiological, morphological and histological similarities with mammals. In fact, many human cytochrome P450 (CYP) enzymes have direct orthologs in zebrafish, suggesting that zebrafish xenobiotic metabolic profiles may be similar to those in mammals. The focus of the review is to analyse the studies that have evaluated the metabolite production in zebrafish over the years, either of the drugs themselves or xenobiotics in general (environmental pollutants, natural products, etc.), bringing a vision of how these works were performed and comparing, where possible, with human metabolism. Early studies that observed metabolic production by zebrafish focused on environmental toxicology, and in recent years the main focus has been on toxicity screening of pharmaceuticals and drug candidates. Nevertheless, there is still a lack of standardization of the model and the knowledge of the extent of similarity with human metabolism. Zebrafish screenings are performed at different life stages, typically being carried out in adult fish through in vivo assays, followed by early larval stages and embryos. Studies comparing metabolism at the different zebrafish life stages are also common. As with any non-human model, the zebrafish presents similarities and differences in relation to the profile of generated metabolites compared to that observed in humans. Although more studies are still needed to assess the degree to which zebrafish metabolism can be compared to human metabolism, the facts presented indicate that the zebrafish is an excellent potential model for assessing xenobiotic metabolism.

Abstract
Organophosphate esters (OPEs) draw growing concern about characterizing the potential risk on environmental health due to its wide usage and distribution. Two typical types of organophosphate esters (OPEs): tris (2-chloroethyl) phosphate (TCEP) and tricresyl phosphate (TCP) were selected to evaluate toxicity of OPEs to the soil organism like earthworm (Eisenia fetida). Histopathological examination (H&E), oxidative stress, DNA damage and RT-qPCR was used to identify the effects and potential mechanism of their toxicity. Hameatoxylin and eosin (H&E) demonstrated that intestinal cells suffered serious damage, and the observed up-regulation of chitinase and cathepsin L in mRNA levels confirmed it. Both TCEP and TCP significantly increased the DNA damage when the concentrations exceeded 1 mg/kg (p < 0.01), and a dose-response relationship was observed. In addition, TCEP and TCP also changed the acetylcholinesterase (AChE) activity and expression of genes associated with neurotoxic effects in earthworms even under exposure to low OPEs concentration (0.1 mg/kg). Moreover, genes associated with nicotinic acetylcholine receptors (nAChR) and carrier protein further demonstrated that highest concentration of TCEP (10 mg/kg) may have an overloading impact on the cholinergic system of E. fetida. Integrated Biological Response index (IBRv2) showed that TCEP exerted stronger toxicity than TCP under the same concentrations. We deduced that the observed intestinal damage, oxidative stress and neurotoxic effect might be the primary mechanisms of TCEP and TCP toxicity. This study provides insight into the toxicological effects of OPEs on earthworm model, and may be useful for risk assessment of OPEs on soil ecosystems.

Abstract
Tris(2-butoxyethyl) phosphate (TBOEP) and tris( n-butyl) phosphate (TNBP) are the most commonly used alkyl organophosphate esters (alkyl-OPEs), and they increasingly accumulate in organisms and create potential health hazards. This study examined the metabolism of TNBP and TBOEP in Carassius carassius liver and intestinal microsomes and the production of their corresponding monohydroxylated and dealkylated metabolites. After 140 min of incubation with fish liver microsomes, the rapid depletion of TNBP and TBOEP were both best fitted to the Michaelis-Menten model (at administrated concentrations ranging from 0.5 to 200 μM), with a CLint (intrinsic clearance) of 3.1 and 3.9 μL·min-1·mg-1 protein, respectively. But no significant ( P > 0.05) biotransformation was observed for these compounds in intestinal microsomes at any administrated concentrations. In fish liver microsomes assay, bis(2-butoxyethyl) hydroxyethyl phosphate (BBOEHEP) and bis(2-butoxyethyl) 3-hydroxyl-2-butoxyethyl phosphate (3-OH-TBOEP) were the most abundant metabolites of TBOEP, and dibutyl-3-hydroxybutyl phosphate (3-OH-TNBP) was the predominant metabolite of TNBP. Similarly, the apparent Vmax values (maximum metabolic rate) of BBOEHEP and 3-OH-TNBP were also respectively highest among those of other metabolites. Further inhibition studies were conducted to identify the specific cytochrome P450 (CYP450) isozymes involved in the metabolism of TNBP and TBOEP in liver microsomes. It was confirmed that CYP3A4 and CYP1A were the significant CYP450 isoforms catalyzing the metabolism of TNBP and TBOEP in fish liver microsomes. Overall, this study emphasized the importance of hydroxylated metabolites as biomarkers for alkyl-OPEs exposure, and further research is needed to validate the in vivo formation and toxicological implications of these metabolites.

Abstract
Tri-n-butyl phosphate (TBP) is widely used in various industrial processes and has been detected in all environmental matrices. So far, little work has been done regarding the metabolism of TBP on terrestrial invertebrates. We investigated the metabolism of TBP in the earthworm, Perionyx excavatus, after acute exposure to TBP for one and two days in filter paper contact test, as well as after chronic exposure for 28 days in soil experiment. Biotransformation products were identified by using liquid chromatography coupled with quadrupole time-of-flight mass spectrometry, and by exploiting the information dependent acquisition in tandem mass spectrometry. TBP exhibited low accumulation in earthworm-soil ecosystem at 10 mg/kg and 50 mg/kg. The presence of earthworms significantly enhanced TBP degradation at 50 mg/kg in soil. Dibutyl phosphate and hydroxylated TBP were the major phase I metabolites. Three novel phase II metabolites were identified: ethanol dibutyl phosphate and its sulfate conjugate, and the phosphate conjugate of hydroxylated TBP. Hydroxylation and further phosphorylation dominated metabolism in chronic exposure. An extensive metabolic pathway of TBP in earthworm was proposed. This is the first report of TBP metabolism in terrestrial invertebrates and highlights the necessity to identify metabolites of contaminants when evaluating their bioaccumulation and toxicity.

Abstract
Diterpenoid lactones (DLs) have been reported to be the main hepatotoxic constituents in Dioscorea bulbifera tubers (DBT), a traditional Chinese medicinal herb. The acquisition of early information regarding its metabolism is critical for evaluating the potential hepatotoxicity of DLs. We investigated, for the first time, the main metabolites of diosbulbin A (DIOA), diosbulbin C (DIOC), diosbulbin (DIOG), diosbulbin (DIOM) and diosbulbin (DIOF) in adult zebrafish. By using ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF MS), 6, 2, 7, 5 and 4 metabolites of DIOA, DIOC, DIOF, DIOM and DIOG were identified in the zebrafish body and the aqueous solution, respectively. Both phase-I and phase-II metabolites were observed in the metabolic profiles and the metabolic pathways involved in hydroxyl reduction, glucuronidation, glutathione conjugation and sulfation. The above results indicated that hepatocytic metabolism might be the major route of clearance for DLs. This study provided important information for the understanding of the metabolism of DLs in DBT.

Abstract
Fluoxastrobin is a new strobilurin fungicide, similar to azoxystrobin and pyraclostrobin. Before the wide application of fluoxastrobin, the present study was performed to assay the acute and chronic toxicity of fluoxastrobin on zebrafish (Danio rerio). The 96-hour median lethal concentration (96h LC50) after initiation of zebrafish exposure to fluoxastrobin was 0.51mg/L with a 95% confidence interval of 0.45 to 0.57mg/L, indicating that fluoxastrobin was highly toxic to zebrafish. As endpoints, we assayed the levels of reactive oxygen species (ROS), malondialdehyde (MDA), the activities of superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), and the degree of DNA damage at three different doses, 0.001, 0.01, and 0.1mg/L on days 7, 14, 21, and 28. The antioxidant enzymes partially ameliorated the ROS induced by fluoxastrobin t and were in turn inhibited by excess ROS, especially at 0.1mg/L. Lipid peroxidation and DNA damage were stimulated by ROS. The fluoxastrobin contents of the tested solutions were also determined; at the fluoxastrobin doses of 0.001, 0.01, and 0.1mg/L, the contents on day 28 were 3.9, 5.0, and 0.64% greater than those on day 0. Thus, fluoxastrobin was relatively stable in an aquatic environment. In addition, the present study provided more information regarding the toxic effects of fluoxastrobin and the scientific methods for selection and evaluation of fungicides in the future.

Abstract
Although organophosphate esters (OPEs) have been detected with growing frequency in water ecosystems, the underlying accumulation mechanisms of these compounds in fish are still unknown. Here, we investigated the tissue-specific accumulation and depuration of seven OPEs in adult zebrafish at three levels (0, 1/150 LC50 (environmentally relevant level), and 1/30 LC50 per OPE congener) in laboratory after 19 days exposure and 3 days depuration. The bioaccumulation of OPEs varied among tissues. Muscle contained the lowest level of OPEs and liver had the highest level of two (TPP and TCEP) of the seven OPEs at steady state. The high levels and slow depuration rates of TDCIPP, TPHP, and TCP observed in roe indicated that the accumulated OPEs were potentially stored in roe and transferred to the next generation. After examination of the major metabolites (organophosphate diesters) in selected tissues, a physiologically based toxicokinetic (PBTK) model used in fish was adopted to explore the key factors affecting the bioaccumulation of OPEs in zebrafish. Biotransformation of OPEs with polychlorinated alkyl moieties (i.e. TDCIPP) and aryl moieties (i.e. TPHP and TCP) has more significant impacts on the accumulation than those of OPEs with alkyl or short chain chlorinated alkyl moieties. Furthermore, the partition process between tissues and blood was also investigated, and was demonstrated to be the dominant process for OPEs accumulation in zebrafish. This study provides critical information on the bioaccumulation, tissue distribution, and metabolization of OPEs in relation with OPE structures in fish, as well as the underlying bioaccumulation mechanisms/pathways of OPEs in aquatic life.
