Abstract
Chemical induced changes in fish biomarkers vitellogenin (VTG), secondary sex characteristics (SSC), and sex ratio indicate modes/mechanisms of action (MOAs) of EAS (estrogen, androgen and steroidogenesis) pathways. These biomarkers could be used for defining MOAs and the causal link between MOAs and adverse effects in fish for the identification of endocrine disrupting chemicals (EDCs). This paper compiled data sets of 150 chemicals for VTG, 57 chemicals for SSC and 38 chemicals for sex ratio in fathead minnow, medaka and zebrafish. It showed 1) changes in fish biomarkers can indicate the MOAs as anticipated; 2) in addition to EAS pathways, chemicals with non-EAS pathways induced changes in fish biomarkers; 3) responses of fish biomarkers did not always follow the anticipated patterns of EAS pathways. These responses may result from the interaction of chemical-induced multiple MOAs and confounding factors like fish diet, infection, culture conditions, general toxicity and stress response. The complex response of fish biomarkers to a chemical of interest requires EDC testing at multiple biological levels. Interpretation of fish biomarker data should be combined with relevant information at different biological levels, which is critical for defining chemical specific MOAs. The utility of fish biomarker data for identification, classification, PBT assessment, risk assessment, and testing of EDCs in the regulatory context was discussed. This paper emphasizes the importance of fish biomarker data in the regulatory context, a weight of evidence approach for the interpretation of fish biomarker data and the need for defining levels of evidence for the identification of EDCs.

Exposing native cyprinid (Barbus plebejus) juveniles to river sediments leads to gonadal alterations, genotoxic effects and thyroid disruption. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2015; 169:223-239.

Abstract
Juveniles (50 days post hatch) of a native cyprinid fish (Barbus plebejus) were exposed for 7 months to sediments from the River Lambro, a polluted tributary impairing the quality of the River Po for tens of kilometers from their confluence. Sediments were collected upstream of the city of Milan and downstream at the closure of the drainage basin of the River Lambro. Chemical analyses revealed the presence of a complex mixture of bioavailable endocrine-active chemicals, with higher exposure levels in the downstream section of the tributary. Mainly characterized by brominated flame retardants, alkylphenols, polychlorinated biphenyls, and minor co-occurring personal care products and natural hormones, the sediment contamination induced reproductive disorders, as well as other forms of endocrine disruption and toxicity. In particular, exposed male barbel exhibited higher biliary PAH-like metabolites, overexpression of the cyp1a gene, vitellogenin production in all specimens, the presence of oocytes (up to 22% intersex), degenerative alterations in their testis, liver fat vacuolization, a marked depression of total thyroxine (T4) and triiodothyronine (T3) plasma levels, and genotoxic damages determined as hepatic DNA adducts. These results clearly demonstrate that Lambro sediments alone are responsible for recognizable changes in the structure and function of the reproductive and, in general, the endocrine system of a native fish species. In the real environment, exposure to waterborne and food-web sources of chemicals are responsible for additional toxic loads, and the present findings thus provide evidence for a causal role of this tributary in the severe decline observed in barbel in recent decades and raise concern that the fish community of the River Po is exposed to endocrine-mediated health effects along tens of kilometres of its course.

Abstract
17Alpha-ethinylestradiol (EE2), used for birth control in humans, is a potent estrogen that is found in wastewater at low concentrations (ng/l). EE2 has the ability to interfere with the endocrine system of fish, affecting reproduction which can result in population level effects. The objective of this study was to determine if dietary exposure to EE2 would alter gene expression patterns and key pathways in the liver and ovary and whether these could be associated with reproductive endpoints in female largemouth bass during egg development. Female LMB received 70ng EE2/g feed (administered at 1% of body weight) for 60 days. EE2 dietary exposure significantly reduced plasma vitellogenin concentrations by 70%. Hepatosomatic and gonadosomatic indices were also decreased with EE2 feeding by 38.5% and 40%, respectively. Transcriptomic profiling revealed that there were more changes in steady state mRNA levels in the liver compared to the ovary. Genes associated with reproduction were differentially expressed, such as vitellogenin in the liver and aromatase in the gonad. In addition, a set of genes related with oxidative stress (e.g. glutathione reductase and glutathione peroxidase) were identified as altered in the liver and genes associated with the immune system (e.g. complement component 1, and macrophage-inducible C-type lectin) were altered in the gonad. In a follow-up study with 0.2ng EE2/g feed for 60 days, similar phenotypic and gene expression changes were observed that support these findings with the higher concentrations. This study provides new insights into how dietary exposure to EE2 interferes with endocrine signaling pathways in female LMB during a critical period of reproductive oogenesis.

Abstract
The toxic effects of bisphenol A (BPA) in aquatic organisms have attracted global attention. However, few studies have investigated its effects at the gene transcription level. In this study, we measured the transcriptional response of a set of genes associated with the hypothalamic-pituitary-gonadal axis following BPA exposure during the early life stage of Japanese medaka. Transcription of vitellogenin genes was induced in both sexes, indicating estrogenic disruption. However, changes in transcription of the steroid hormone receptor gene and steroidogenesis-regulating genes suggest that BPA also acts as an androgen receptor antagonist. BPA exposure also decreased the hatchability of medaka embryos and increased the growth of female larvae. These pronounced gender-specific effects observed in this study demonstrate that it is important to identify the sex of fish in the early life stage.

Abstract
Enzymatic removal of p-alkylphenols from aqueous solutions was investigated through the two-step approach, the quinone conversion of p-alkylphenols with mushroom tyrosinase (EC 1.14.18.1) and the subsequent adsorption of quinone derivatives enzymatically generated on chitosan beads at pH 7.0 and 45 degrees C as the optimum conditions. This technique is quite effective for removal of various p-alkylphenols from an aqueous solution. The % removal values of 97-100% were obtained for p-n-alkylphenols with carbon chain lengths of 5 to 9. In addition, removal of other p-alkylphenols was enhanced by increasing either the tyrosinase concentration or the amount of added chitosan beads, and their % removal values reached >93 except for 4-tert-pentylphenol. This technique was also applicable to remove 4-n-octylphenol (4NOP) and 4-n-nonylphenol (4NNP) as suspected endocrine disrupting chemicals. The reaction of quinone derivatives enzymatically generated with the chitosan's amino groups was confirmed by the appearance of peaks for UV-visible spectrum measurements of the chitosan films incubated in the p-alkylphenol and tyrosinase mixture solutions. In addition, 4-tert-pentylphenol underwent tyrosinase-catalyzed oxidation in the presence of hydrogen peroxide.

Abstract
We evaluated the utility of gene-transcriptional responses in the liver of mosquitofish (Gambusia affinis), a species introduced to many countries and therefore widely available, for detecting endocrine-disrupting activity in water. Exposure to β-naphthoflavone, an aryl hydrocarbon receptor (AhR) agonist, significantly increased the transcript of the cytochrome P4501A gene (cyp1a), peaking at 24 h, in both sexes at concentrations of 10 µg/L or more. 17β-Estradiol (E(2) ) at 500 ng/L increased the number of males showing gene transcription of precursors of yolk protein, vitellogenin (Vtga, Vtgb, and Vtgc), at 24, 48, and 72 h. Exposure for 48 h to bisphenol A (BPA), an estrogen mimic, also increased vtg-positive males at 1 mg/L or more. Leachate from a Japanese stable-type landfill significantly increased vtg-positive males after 48 h exposure, and the in vitro activity of the leachate against the estrogen receptor (ER) was estimated as an E(2) equivalent of 240 ng/L by yeast transfected with the ER. Chemical analysis showed that major contributors to the ER activation were BPA and 4-tert-octylphenol. This leachate and drainage water from a control-type landfill had AhR activities, estimated by yeast with the AhR, but had no significant effect on cyp1a transcription. These results showed that mosquitofish are suitable for detecting in vivo AhR and ER effects, but are insensitive to E(2).

Abstract
In Japan, the leachates from 'stable type' landfills for industrial wastes are not controlled, and this has given rise to concerns about the possible pollution of surrounding environmental waters, especially by endocrine disrupting chemicals leaching from plastic and rubber wastes. To accurately assess the estrogenic potential of the landfill leachates by both in vitro and in vivo approaches, we confirmed gene-transcriptional responses in recombinant yeast cells and in Japanese medaka fish to estrogenic compounds, and applied these transcription assays to leachate samples. The yeast carrying the estrogen receptor (ER) of medaka and an ER-mediated response pathway responded to both the natural estrogen, 17β-estradiol (E2), and an industrial compound, bisphenol A (BPA), and the effective concentration of BPA was about 2.0×10(3) times that of E2. Transcripts of all genes coding for precursors of yolk protein, vitellogenin (vtg1 and vtg2), and precursors of egg envelope subunit proteins, choriogenins (chgh and chgl), increased in a concentration dependent manner in the livers of male medaka exposed to BPA or E2, and, except for chgh, reached peaks at exposure times of 48h. Although many fish in control groups did not have vtg transcripts, the incidence of vtg transcriptions also increased in a concentration dependent manner with exposure. The minimum effective concentrations of BPA at 48h were 0.5mg/L for chgh and vtg2, 2mg/L for vtg1 and 4mg/L for chgl, while those of E2 were 10ng/L for chgh and chgl and 30ng/L for vtg1 and vtg2. All leachates sampled at 3 landfill sites exerted in vitro estrogenic action. The E2 equivalent of the most potent leachate was 375ng/L for the yeast ER assay. This leachate sample significantly increased the transcripts of chgh, vtg1 and vtg2, but not chgl, in the medaka. In addition, chemical analysis showed that bisphenol A, 4-tert-octylphenol and 4-nonylphenol were the main contributors to the estrogenicity of the leachates. This study indicated that this type of landfill may adversely affect the reproductive functions of fish living in the surrounding area by leakage of industrial estrogenic compounds.

Abstract
An increasing number of widely used industrial and agricultural chemicals are being found to cause endocrine disruption. In fishes, xenoestrogens can induce female proteins, and in some cases, the development of testis-ova, demonstrating feminization of males. In this study we analyzed the effect of an acute exposure of adult male Cichlasoma dimerus fish to estradiol (E(2)) and octylphenol (OP). E(2) and OP were injected at 10 and 50 μg/g body weight doses, respectively. After a single OP dose, liver was processed for RNA extraction at 1, 3, 12, 24, and 72 h. PCR was performed using cDNA and primers for egg coat or zona pellucida proteins (ZP). Genes encoding ZPB and ZPC isoforms were sequenced. E(2)-induced fish were sacrificed at 72 h. Using multiple OP or E(2) injections, blood and surface mucus were sampled on days 0, 3, 6, 9, and 13. On day 13 fish were sacrificed for liver and testis dissection. Histological examination of E(2) and OP-treated fish livers showed cellular disarray and intense cytoplasmatic basophilia within hepatocytes, probably due to increased mRNA synthesis, as well as hypertrophied euchromatic nuclei, and conspicuous nucleoli, indicative of augmented cell activity. An abnormal amount of sperm and immature germ cells within the testis lumen were seen in treated fish, suggesting reproductive impairment. Both plasma and mucus revealed the presence of ZP (and vitellogenin) at day 3 and thereafter with E(2) treatment, using Western and Dot blot techniques; OP effects were delayed in time. These results validate the analysis of mucus by Dot blot as an easy and rapid technique to address endocrine disruption caused by OP. Quantitative gene expression showed induction of liver ZPB and ZPC upon OP injection; muscle, brain, and intestine did not express any ZP. Both ZPs were induced at 1h post injection, but only ZPB expression was statistically significant. At 12h, both ZPs increased significantly, reaching the same levels of E(2)-challenged males after 72 h. Therefore, OP mimicked the action of E(2) with a prompt and strong xenoestrogenic effect, evidenced by the early response through mRNA and protein expression of ZP and the concomitant histological liver and testis alterations.

Abstract
Japanese medaka (Oryzias latipes) is a valuable model organism in reproductive and developmental toxicity testing. The purpose of this experiment is to assess the response of medaka to aquatic estrogen exposure over the course of 1 year. Each week, three pairs of adult male medaka were exposed separately for 4 days (100% static renewal daily) to 17beta-estradiol at a nominal level of 25 microg/l, with a fourth pair of fish exposed separately to an ethanol control. Vitellogenin (VTG) induction was observed each week, with hepatic and plasma VTG levels significantly higher (P < 0.001) than reported for ethanol control specimens. A significant (P < 0.001) increasing trend was observed for plasma VTG results over the duration of the study, whereas a decreasing trend (P = 0.030) of hepatic VTG was evident. A Durbin-Watson test, however, did not demonstrate any serial autocorrelation of hepatic (d = 1.180) or plasma (d = 1.311) VTG levels over the duration of the study. Time-series transformations of the hepatic and plasma VTG data did not reveal any significant seasonal or behavioral patterns. However, significant intermittent peaks in VTG production were observed in both tissue types during the study. These data indicate that some consideration must be taken to time long-term medaka exposures (>20 weeks) in order to eliminate any influence of cyclic changes on plasma VTG response. Alternatively, hepatic cytosolic measurement of VTG appears to show a more sensitive response to aquatic estrogen exposure.

Abstract
Nonylphenol (NP), a xenoestrogen ubiquitously found in aquatic ecosystems, is of high environmental concern. The present work assessed the effects of exposure to NP on locomotor activity and social behavior in male and female zebrafish (Danio rerio), to evaluate the possible hazard of NP to fish behavior and to pursue a potential biomarker of NP contamination. Fish were randomly divided into six groups. Five groups were receiving 0.1, 1, 10, 50 and 100 microg/L nominal concentrations of NP for 60 days, respectively. A sixth control group was given the same treatment as the other five groups, but no NP. Locomotor activity, aggressive behavior, group preference and leaving shoal were examined. NP exposure showed marked influence on locomotor activity of the male zebrafish, whereas that of the female was not significantly affected by NP. Aggressive behavior and group preference were significantly affected by NP exposure in both male and female groups. Locomotor activity and aggressive behavior of the male and group preference of both male and female zebrafish were clearly inhibited at 100 microg/L NP. No significant alteration in leaving shoal was observed under NP exposure. The results suggested that changes in locomotor activity and aggressive behavior of the male and group preference of both male and female may be used as an ecologically relevant integrative biomarker of NP contamination.

Abstract
The aim of the present study was to assess aquatic contamination by polycyclic aromatic hydrocarbons (PAH), using the 1-hydroxypyrene (1-OHP) content in fish bile as a biochemical marker. A total of 71 chub (Leuciscus cephalus L.) were collected from seven locations on the Svitava and Svratka rivers in and around the industrial city of Brno, Czech Republic. The levels of 1-OHP were determined by reverse phase HPLC with fluorescence detection after deconjugation. Normalising the molar concentration of the biliary 1-OHP to the biliary protein content reduced sample variation. The content of 1-OHP was correlated with the PAH level in bottom sediment and semi-permeable membrane devices (SPMD), which was analyzed by a combination of HPLC/FLD and GC/MS methods. The highest mean values of 1-OHP were found in fish caught at the Svratka River at locations Modřice (169.2 ± 99.7 ng·mg−1 protein) and Rajhradice (152.2 ± 79.7 ng·mg−1 protein), which are located downstream from Brno. These values were significantly (P < 0.05) higher than those obtained from localities Kníničky (98.4 ± 66.1 ng·mg−1 protein) and Bílovice nad Svitavou (64.1 ± 31.4 ng·mg−1 protein). The lowest contents of PAH in sediment and SPMD were found at location Kníničky (1.5 mg·kg−1 dry mass and 19.4 ng·L−1, respectively). The highest contents of PAH in sediment and SPMD were found in Rajhradice (26.0 mg·kg−1 dry mass) and Svitava before junction (65.4 ng·L−1), respectively. A Spearman correlation test was applied to determine the relationship between biliary 1-OHP and the sum of PAH in sediment and SPMD. A positive, but no statistically significant correlation was found. The main impact sources of elevated level of PAHs in sites located downstream from Brno are most probably intensive industrial and agricultural activities and domestic waste.

Abstract
Mozambique tilapia, (Oreochromis mossambicus), are a euryhaline teleost and an important biological model species. Captive male tilapia frequently have high levels of the estrogen-induced yolk precursor protein vitellogenin (Vg), a common indicator of exposure to estrogenic compounds. Sex steroids are found in commercial fish diets, but relatively few studies have examined the relationship between commercial diets and Vg production. In a fasting experiment to ascertain a dietary role in male Vg production, plasma Vg was reduced to negligible levels after 2 weeks of fasting, while no change in estrogen receptor (ER) expression was seen. When male tilapia were fed a squid-based diet that replaced the commercial trout diet, plasma Vg was reduced to undetectable levels over 40 days, concomitant with significant reductions in hepatic expression of Vgs A, B, and C, and ERbeta, compared with control fish fed commercial trout diet. Female tilapia fed the squid-based for 20 days had no change in these parameters. When male tilapia were fed a defined, soy-based diet, plasma Vg reduced to 20% of levels in fish given either commercial trout diet or a defined, fishmeal-based diet. Overall, results from these studies suggest that estrogens in a commercial trout diet induce vitellogenin production by increasing expression of Vg, but not ER genes in male tilapia.

Abstract
Despite the fact that the biological processes of chiral compounds are enantioselective, the endocrine disruption activity and uptake of chiral contaminants with respect to enantioselectivity has so far received limited research. In this study, the estrogenic potential and uptake of the enantiomers of a newer pyrethroid insecticide, bifenthrin (BF), were investigated. Significant differences in estrogenic potential were observed between the two enantiomers in the in vitro human breast carcinoma MCF-7 cell proliferation assay (i.e., the E-SCREEN assay) and the in vivo aquatic vertebrate vitellogenin enzyme-linked immunosorbent assay (ELISA). In the E-SCREEN assay, the relative proliferative effect ratios of 1S-cis-BF and 1R-cis-BF were 74.2% and 20.9%, respectively, and the relative proliferative potency ratios were 10% and 1%, respectively. The cell proliferation induced by the two BF enantiomers may be through the classical estrogen response pathway via the estrogen receptor (ER), as the proliferation induced by the enantiomers could be completely blocked when combined with 10-6 mol/L of the ER antagonist ICI 182,780. Measurement of vitellogenin induction in Japanese medaka (Oryzias latipes) showed that, at an exposure level of 10 ng/mL, the response to 1S-cis-BF was about 123 times greater than thattothe Renantiomer. Significant selectivity also occurred in the uptake of BF enantiomers in the liver and other tissues of J. medaka. These results together suggest that assessment of the environmental safety of chiral insecticides should consider enantioselectivity in acute and chronic ecotoxicities such as endocrine disruption.

Abstract
In recent years, concern has been raised about the ability of some classes of environmental contaminants to disrupt the endocrine system of both humans and wildlife. In this study, juvenile turbots (Psetta maxima) were exposed under laboratory conditions to selected waterborne contaminants: oil, oil spiked with alkylphenols, bisphenol A, diallylphthalate, tetrabrominated diphenyl ether 47, and p-nonylphenol as a positive control for "estrogenic-type" effects. This work focused on sex steroids, because these hormones play a key role in the reproduction process. Analytical procedures, involving the off-line coupling of solid phase extraction and gas chromatography/mass spectrometry, were developed for the determination of 12 endogenous sex steroids levels in fish plasma, bile, and gonads. Because of the sexual immaturity of the fish used in this study, however, only six steroids could be detected in juvenile turbots. Bisphenol A and p-nonylphenol exhibited the highest potency towards steroids dynamics, lowering the ratio of androgens to estrogens in all three studied matrices. However, these two chemicals had different modes of action, because p-nonylphenol induced a decrease of androstenedione and 11-ketotestosterone levels, whereas bisphenol A exposure led to an elevation of estrone level. Overall, these two chemicals seemingly disrupted the activity of some steroidogenesis enzymes, leading to serious hormonal imbalance in juvenile turbot.

Abstract
The effects of oral administration of tamoxifen, 17α-ethynylestradiol (EE2), flutamide, and methyltestosterone (MT), on plasma vitellogenin levels of male and female medaka were investigated. Medaka were fed diets containing different concentrations of these chemicals for 7 days, and these plasma vitellogenin levels were measured. Tamoxifen increased significantly the vitellogenin levels in male, but inhibited the normal vitellogenin induction in female in the high concentration groups. EE2 increased significantly vitellogenin levels in both sexes. Flutamide increased significantly the vitellogenin levels in female, but gave no effects on male. MT inhibited the normal vitellogenin induction in female, but increased slightly vitellogenin levels in male without a clear tendency. Administration of tamoxifen, EE2, flutamide, and MT showed the different pattern in vitellogenin levels in both sexes.
