Abstract
Natural and synthetic environmental estrogens (EEs) are widespread and have received extensive attention. Our previous studies demonstrated that depletion of the cytochrome P450 17a1 gene (cyp17a1) leads to all-testis differentiation phenotype in zebrafish and common carp. In the present study, cyp17a1-deficient zebrafish with defective estrogen biosynthesis were used for the evaluation of EEs, as assessed by monitoring vitellogenin (vtg) expression. A rapid and sensitive assessment procedure was established with the 3-day administration of estradiol (E2), followed by examination of the transcriptional expression of vtgs in our cyp17a1-deficient fish. Compared with the control fish, a higher E2-mediated vtg upregulation observed in cyp17a1-deficient zebrafish exposed to 0.1 μg/L E2 is known to be estrogen receptor-dependent and likely due to impaired in vivo estrogen biosynthesis. The more responsive vtg expression in cyp17a1-deficient zebrafish was observed when exposed to 200 and 2000 μg/L bisphenol A (BPA) and perfluoro-1-octanesulfonate (PFOS). The estrogenic potentials of E2, BPA, and PFOS were compared and assessed by the feminization effect on ovarian differentiation in cyp17a1-deficient zebrafish from 18 to 50 days postfertilization, based on which a higher sensitivity of E2 in ovarian differentiation than BPA and PFOS was concluded. Collectively, through the higher sensitivity to EEs and the capacity to distinguish chemicals with different estrogenic potentials exhibited by the all-male cyp17a1-deficient zebrafish with impaired estrogen biosynthesis, we demonstrated that they can be used as an excellent in vivo model for the evaluation of EEs.

Abstract
Exposure to 2, 2', 4, 4'-tetrabromodiphenyl ether (BDE-47) has been found to have an impact on reproductive output and endocrine function in female zebrafish (Danio rerio). However, the transgenerational effects of BDE-47 have not been fully explored in previous reports. In this study, female zebrafish were exposed to BDE-47 for three consecutive weeks. The oogenesis, sex hormones, reproductive histology, and transcriptional profiles of genes along the hypothalamus-pituitary-gonad (HPG) axis were assessed in the exposed-F0 generation. After mating with unexposed males, the transgenerational effects of BDE-47 were evaluated on the basis of histopathology, morphometry and toxicogenome of the unexposed F1 generations at the larval stage. Results indicated that exposure to BDE-47 impaired reproductive capacity, disrupted endocrine system in F0 zebrafish, and compromised craniofacial skeletons and vertebrae development in F1 generations. In addition, through the use of toxicogenomics approach, immune-responsive pathways were found to be significantly enriched, and the transcript expression profiling of immune-related DEGs (IRDs) were dramatically inhibited in F1 generations following maternal BDE-47 exposure, indicating its immunotoxicity to offspring larvae. These findings advance our understanding of the transgenerational toxicity of BDE-47 and advocate for a more comprehensive assessment of other PBDE congeners through histomorphometry and toxicogenomic approaches.

Abstract
Quantitative reverse transcription polymerase chain reaction (RT-qPCR) is commonly used to measure the mRNA expression of target genes in zebrafish. Gene expression values from RT-qPCR are typically reported as relative fold-changes, and relative quantification of RT-qPCR data incorporates primer amplification efficiency values for each target gene. We describe the influence of the primer amplification efficiency analysis method on RT-qPCR gene expression fold-change calculations. This report describes (1) a sample analysis demonstrating incorporation of primer amplification efficiency into RT-qPCR analysis for comparing gene expression of a gene of interest between two groups when normalized to multiple reference genes, (2) the influence of differences in primer amplification efficiencies between measured genes on gene expression differences calculated from theoretical delta-Cq (dCq) values, and (3) an empirical comparison of the influence of three methods of defining primer amplification efficiency in gene expression analyses (delta-delta-Cq [ddCq], standard curve, LinRegPCR) using mRNA measurements of a set of genes in zebrafish embryonic development. Given the need to account for the influence of primer amplification efficiency along with the simplicity of using software programs (LinRegPCR) to measure primer amplification efficiency from RT-qPCR data, we encourage using empirical measurements of primer amplification efficiency for RT-qPCR analysis of differential gene expression in zebrafish.

Abstract
Exposure to BPA is recently shown to affect cartilage development in teleost fishes; whether BPS and BPAF, its two most frequently used phenolic analogues have similar effect, however, remains unclear. Here, we utilize zebrafish (Danio rerio) as an in-vivo larval model for systematic comparison of the pharyngeal arch-derived cartilage developmental toxicity of BPA, BPS and BPAF. Zebrafish are continuously exposed to three bisphenol analogues (3-BPs) at a range of concentrations since the embryonic stage (0.5 hpf), and identified cartilage malformations of the mandibular and hyoid pharyngeal arches at larval stage (120 hpf). BPA and BPAF prolong length and broaden cartilage angles; however, BPS shortens length and narrows the angles of skull cartilages. The results of the comparative transcriptome show that FoxO and MAPK signaling pathways are closely associated with the toxicity of BPA and BPAF, while BPS exposure affects energy metabolism-related pathways. Moreover, exposure to 3-BPs have an impact on the oxidative stress status. Our data collectively indicate that BPS and BPAF may not be safer than BPA regarding the impact on pharyngeal cartilage development in fish model, the mechanisms still need explorations, and that these two analogues should be applied with caution.

Abstract
Co-existence of mycotoxins may pose a greater risk. It remains less known about the toxic effect of co-exposure of zearalenone (ZEA) and deoxynivalenol (DON) on aquatic life. In the present study, the toxic effects of the combine treatment of ZEA and DON on zebrafish (Danio rerio) embryos were investigated. The results showed that the combined treatment of ZEA (200, 400, 800 μg/L) and DON (4000 μg/L) did not cause apparent deaths, but induced a developmental toxicity as indicated by decreased movement times and heartbeat. At 96 h post-fertilization (hpf), co-exposure of ZEA and DON (Z400 + D4000 and Z800 + D4000 group) led to significant oxidative stress as evidenced by the increased ROS level and MDA content, as well as the changes of antioxidant enzymes (SOD, CAT and GPX) and their genes. Besides, the combined treatment of ZEA and DON triggered hepatotoxicity as shown by the changes of Fabp10a, Gclc, Gsr, Nqo1 genes, apoptosis through upregulating apoptosis-related genes (p53, Caspase-9, Caspase-3) and downregulating Bcl-2 gene, as well as inflammation by promoting the expression of IL-1β, IL-6, TNF-α, TLR4, MyD88, NF-κBp65 genes. These results indicated the co-exposure of ZEA and DON caused oxidative stress, leading to stronger potential toxic effects to zebrafish embryos than their respective single treatment. Therefore, more attention should be paid to risk management of the co-contamination of mycotoxins.

Abstract
The aim of this study was to examine the effect of microRNA 92b-3p (MiR92b-3p) overexpression on the embryonic development of zebrafish. A synthetic MiR92b-3p analogue (mirVana™ mimic, in vivo-ready) was injected at doses up to 5 ng/embryo into the yolk sac of embryos (2-16 cell stage). At 24 h post fertilization (hpf), the locomotor activity of the embryos was measured, and after hatching (72 hpf), the rates of malformation occurrence, hatching, and mortality were determined. Next, the larvae were fixed for histological and molecular examinations. Exposure to the MiR92b-3p mimic impaired embryonic development, leading to increased occurrence of malformations (i.e., pericardial edema, spine curvature, smaller eyes), decreased locomotor activity and hatching rate, and increased mortality. Importantly, the mimic affected retinal differentiation and lens formation during zebrafish embryogenesis, which suggests that MiR92b-3p could be an important factor in the regulation of fish embryogenesis and ocular development. The expression level of MiR92b-3p was substantially higher in the exposed larvae than in the untreated larvae, indicating that the mimic was successfully delivered to the zebrafish. Although screening of potential MiR92b-3p target genes suggested some changes in their expression levels, these results were inconclusive. Together, this study indicates that MiR92b-3p mimic impairs zebrafish embryonic development, and further research is necessary to identify the MiR92b-3p-regulated cell pathways involved in the impairment of the fish's development.

Abstract
Eels are important aquaculture species for which an increasing number of reference genes are being identified and applied. In this study, five housekeeping genes [RPL7 (ribosomal protein L7), 18 S (18 S ribosomal RNA), EF1A (elongation factor 1α), ACTB (β-actin) and GAPDH (glyceraldehyde-3-phosphate dehydrogenase)] were chosen to evaluate their reliability as reference genes for quantitative real-time PCR (qPCR) for the study of Anguilla anguilla. The expression of the selected genes in different eel tissues was determined using qPCR at different growth stages or upon challenge by Anguillid herpesvirus (AngHV), and the expression levels of these genes were then compared and evaluated using the geNorm and NormFinder algorithms. Then, RefFinder was used to comprehensively rank the examined housekeeping genes. Interestingly, the expression of the evaluated housekeeping genes exhibited tissue-dependent and treatment-dependent variations. In different growth periods A. anguilla tissues, the most stable genes were the following: ACTB in mucus; 18 S in skin and kidney; RPL7 in muscle, gill, intestine and brain; EF1A in heart and liver; and GAPDH in spleen. In contrast, in AngHV-challenged A. anguilla tissues, the most stable genes were the following: 18 S in mucus; RPL7 in skin, gill, heart, spleen, kidney and intestine; EF1A in muscle and liver; and ACTB in brain. Further comparison analysis indicated that the expression of RPL7 and EF1A was stable in multiple A. anguilla tissues in different growth periods and in eels challenged by AngHV. Nonetheless, the expression level of GAPDH in eel tissues was lower, and it was unstable in several tissues. These results indicated that the selection of reference genes for qPCR analysis in A. anguilla should be made in accordance with experimental parameters, and both RPL7 and EF1A could be used as reference genes for qPCR study of A. anguilla at different growth stages or upon challenge by AngHV. The reference genes identified in this study could improve the accuracy of qPCR data and facilitate further studies aimed at understanding the biology of eels.

Abstract
Atractylodes lancea, commonly known as Kod-Kamao in Thai, a traditional medicinal herb, is being developed for clinical use in cholangiocarcinoma. β-eudesmol and atractylodin are the main active components of this herb which possess most of the pharmacological properties. However, the lack of adequate toxicity data would be a significant hindrance to their further development. The present study investigated the toxic effects of selected concentrations of β-eudesmol and atractylodin in the heart, liver, and endocrine systems of zebrafish embryos. Study endpoints included changes in the expression of genes related to Na/K-ATPase activity in the heart, fatty acid-binding protein 10a and cytochrome P450 family 1 subfamily A member 1 in the liver, and cortisol levels in the endocrine system. Both compounds produced inhibitory effects on the Na/K-ATPase gene expressions in the heart. Both also triggered the biomarkers of liver toxicity. While β-eudesmol did not alter the expression of the cytochrome P450 family 1 subfamily A member 1 gene, atractylodin at high concentrations upregulated the gene, suggesting its potential enzyme-inducing activity in this gene. β-eudesmol, but not atractylodin, showed some stress-reducing properties with suppression of cortisol production.

Abstract
Benzophenones (BPs) are a class of UV absorber commonly used in skin care products like sunscreens. With its wide range of application, its environmental and human hazards have received much attention in recent days. Previous studies on the toxicity of BPs mainly focused on its endocrine-disrupting effects, but there are limited studies on its neurodevelopment and neurotoxicity. Herein, using the zebrafish model we studied the neurodevelopmental- and neuro-toxicity of benzophenone 1 (BP1) (0.8, 1.0, 1.2, 1.6, and 2.4 μg/mL). As a result, BP1 led to an increase of embryo mortality, a decrease in hatching rate, and an increase in the rate of developmental abnormalities in a concentration-dependent manner. BP1 also caused developmental defects in the central nervous system (CNS) and dopaminergic (DA) neurons. Accordingly, BP1 injured larval zebrafish general locomotion and response to stimuli in light/dark challenge. In adult zebrafish, BP1 exposure (1, 10, 100, 1000 μg/L) caused inhibition of learning and memory abilities in the T-maze tests, and inhibited exploratory behavior and activity in the novel tank diving tests. Further, transcription levels of genes related to neurotoxicity, neurodevelopment, and anxiety revealed that BP1 may affect the development and function of the myelin sheath, inducing structural and functional defects of CNS, manifested as abnormal behaviors such as anxiety. Hence, the current study revealed the neurodevelopmental toxicity and neurotoxicity of BP1, expanded our knowledge about the toxic effects of BP1 on organisms, posing a possible threat to the environment and human health.

Aqueous Extract of Psiloxylon mauritianum, Rich in Gallic Acid, Prevents Obesity and Associated Deleterious Effects in Zebrafish. Antioxidants (Basel) 2022; 11:antiox11071309. [PMID: 35883799 PMCID: PMC9312056 DOI: 10.3390/antiox11071309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 06/26/2022] [Accepted: 06/26/2022] [Indexed: 12/04/2022] Open
Abstract
Obesity has reached epidemic proportions, and its prevalence tripled worldwide between 1975 and 2016, especially in Reunion Island, a French overseas region. Psiloxylon mauritianum, an endemic medicinal plant from Reunion Island registered in the French pharmacopeia, has recently gained interest in combating metabolic disorders because of its traditional lipid-lowering and “anti-diabetic” use. However, scientific data are lacking regarding its toxicity and its real benefits on metabolic diseases. In this study, we aim to determine the toxicity of an aqueous extract of P. mauritianum on zebrafish eleutheroembryos following the OECD toxicity assay (Organization for Economic Cooperation and Development, guidelines 36). After defining a non-toxic dose, we determined by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) that this extract is rich in gallic acid but contains also caffeoylquinic acid, kaempferol and quercetin, as well as their respective derivatives. We also showed that the non-toxic dose exhibits lipid-lowering effects in a high-fat-diet zebrafish larvae model. In a next step, we demonstrated its preventive effects on body weight gain, hyperglycemia and liver steatosis in a diet-induced obesity model (DIO) performed in adults. It also limited the deleterious effects of overfeeding on the central nervous system (i.e., cerebral oxidative stress, blood-brain barrier breakdown, neuro-inflammation and blunted neurogenesis). Interestingly, adult DIO fish treated with P. mauritianum display normal feeding behavior but higher feces production. This indicates that the “anti-weight-gain” effect is probably due to the action of P. mauritianum on the intestinal lipid absorption and/or on the microbiota, leading to the increase in feces production. Therefore, in our experimental conditions, the aqueous extract of P. mauritianum exhibited “anti-weight-gain” properties, which prevented the development of obesity and its deleterious effects at the peripheral and central levels. These effects should be further investigated in preclinical models of obese/diabetic mice, as well as the impact of P. mauritianum on the gut microbiota.

Medicinal Plant: Potential Toxicity and Therapeutic Effects Based on a Zebrafish Model. Front Pharmacol 2022; 13:832928. [PMID: 35359845 PMCID: PMC8963451 DOI: 10.3389/fphar.2022.832928] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Accepted: 02/04/2022] [Indexed: 12/26/2022] Open
Abstract
Hypericum lanceolatum Lam. (H. lanceolatum) is a traditional medicinal plant from Reunion Island used for its pleiotropic effects mainly related to its antioxidant activity. The present work aimed to 1) determine the potential toxicity of the plant aqueous extract in vivo and 2) investigate its putative biological properties using several zebrafish models of oxidative stress, regeneration, estrogenicity, neurogenesis and metabolic disorders. First, we characterized the polyphenolic composition by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and identified chlorogenic acid isomers, quercetin and kaempferol derivatives as the major compounds. We then evaluated for the first time the toxicity of an aqueous extract of H. lanceolatum and determined a maximum non-toxic concentration (MNTC) in zebrafish eleutheroembryos from 0 to 96 hpf following OECD (Organization for Economic Cooperation and Development) guidelines. This MNTC test was also determined on hatched eleutheroembryos after 2 days of treatment (from 3 to 5 dpf). In our study, the anti-estrogenic effects of H. lanceolatum are supported by the data from the EASZY assay. In a tail amputation model, we showed that H. lanceolatum at its MNTC displays antioxidant properties, favors immune cell recruitment and tissue regeneration. Our results also highlighted its beneficial effects in metabolic disorders. Indeed, H. lanceolatum efficiently reduces lipid accumulation and body mass index in overfed larva- and adult-models, respectively. In addition, we show that H. lanceolatum did not improve fasting blood glucose levels in a hyperglycemic zebrafish model but surprisingly inhibited neurogenesis impairment observed in diabetic conditions. In conclusion, our study highlights the antioxidant, pro-regenerative, anti-lipid accumulation and pro-neurogenic effects of H. lanceolatum in vivo and supports the use of this traditional medicinal plant as a potential alternative in the prevention and/or treatment of metabolic disorders.

Front Endocrinol (Lausanne) 2022; 13:910639. [PMID: 35733778 PMCID: PMC9207535 DOI: 10.3389/fendo.2022.910639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 05/06/2022] [Indexed: 11/13/2022] Open
Abstract
Unlike the Cytochrome P450, family 17, subfamily A, member 1 (Cyp17a1), which possesses both 17α-hydroxylase and 17,20-lyase activities involved in the steroidogenic pathway that produces androgens and estrogens, Cytochrome P450, family 17, subfamily A, polypeptide 2 (Cyp17a2) possesses only 17α-hydroxylase activity and is known essential for the synthesis of cortisol. Besides with expressed in testes and ovaries, where the cyp17a1 is mainly expressed, cyp17a2 is also expressed in the interrenal gland in fish. Until now, the roles of cyp17a2 in fish, especially in sexual traits development and hypothalamic-pituitary-interrenal (HPI) axis, are poorly studied. To investigate the roles of Cyp17a2 in teleosts, the cyp17a2-null zebrafish was generated and analyzed by us. The significantly decreased cortisol concentration was observed both in the cyp17a2-deficient males and females at adult stage. The interrenal gland enlargement, increased pituitary proopiomelanocortin a (pomca) expression, decreased locomotion activity and response to light-stimulated stress were observed in cyp17a2-deficient fish. Intriguingly, the cyp17a2-deficient males were fertile and with normal breeding tubercles on the pectoral fin, but females were infertile, deficient in genital papilla and with decreased gonadosomatic index (GSI). The increased progesterone (P4), 17α,20β-dihydroxy-4-pregnen-3-one (DHP) and 11-ketotestosterone (11-KT) in the cyp17a2-deficient males and females were observed. The increased concentration of testosterone (T) and estradiol (E2) was observed in cyp17a2-/- females and cyp17a2-/- males, respectively. By examining the ovaries development of cyp17a2-deficient fish at 3 months postfertilization (mpf), we observed that the oocytes were over-activated. Taken together, our findings demonstrate that Cyp17a2 is indispensable for production and physiology of cortisol, and cyp17a2-deficiency resulted in diminished cortisol but accumulated P4 and DHP, which may result in the over-activated oocytes in cyp17a2-deficient females.

Biomed Pharmacother 2021; 138:111521. [PMID: 34311525 DOI: 10.1016/j.biopha.2021.111521] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 03/11/2021] [Accepted: 03/17/2021] [Indexed: 11/30/2022] Open
Abstract
Euphorbiae pekinensis Radix (EP) is effective in treating various diseases, but it's toxicity is a major obstacle in use in clinical. Although EP was processed with vinegar to reduce it's toxicity, the detailed mechanism of toxicity in EP have not been clearly delineated. This study investigate the toxicity attenuation-mechanism of Euphorbiae pekinensis after being processed with vinegar (VEP) and the toxic mechanism of four compounds from EP on zebrafish embryos. The contents of four compounds decreased obviously in VEP. Correspondingly, slower development on embryos can be seen as some symptoms like reduction of heart rate, liver area and gastrointestinal peristalsis after exposed to the compounds. Some obvious pathological signals such as pericardial edema and yolk sac edema were observed. Furthermore, the compounds could increase the contents of MDA and GSH-PX and induce oxidative damage by inhibiting the activity of SOD. Also, four compounds could provoke apoptosis by up-regulating the expression level of p53, MDM2, Bax, Bcl-2 and activating the activity of caspase-3, caspase-9. In conclusion, the four compounds play an important role in the toxicity attenuation effects of VEP, which may be related to the apoptosis induction and oxidative damage. This would contribute to the clinical application and further toxicity-reduction mechanism research.

Selective killing of homologous recombination-deficient cancer cell lines by inhibitors of the RPA:RAD52 protein-protein interaction. PLoS One 2021; 16:e0248941. [PMID: 33784323 DOI: 10.1371/journal.pone.0248941] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Accepted: 03/09/2021] [Indexed: 12/29/2022] Open
Abstract
Synthetic lethality is a successful strategy employed to develop selective chemotherapeutics against cancer cells. Inactivation of RAD52 is synthetically lethal to homologous recombination (HR) deficient cancer cell lines. Replication protein A (RPA) recruits RAD52 to repair sites, and the formation of this protein-protein complex is critical for RAD52 activity. To discover small molecules that inhibit the RPA:RAD52 protein-protein interaction (PPI), we screened chemical libraries with our newly developed Fluorescence-based protein-protein Interaction Assay (FluorIA). Eleven compounds were identified, including FDA-approved drugs (quinacrine, mitoxantrone, and doxorubicin). The FluorIA was used to rank the compounds by their ability to inhibit the RPA:RAD52 PPI and showed mitoxantrone and doxorubicin to be the most effective. Initial studies using the three FDA-approved drugs showed selective killing of BRCA1-mutated breast cancer cells (HCC1937), BRCA2-mutated ovarian cancer cells (PE01), and BRCA1-mutated ovarian cancer cells (UWB1.289). It was noteworthy that selective killing was seen in cells known to be resistant to PARP inhibitors (HCC1937 and UWB1 SYr13). A cell-based double-strand break (DSB) repair assay indicated that mitoxantrone significantly suppressed RAD52-dependent single-strand annealing (SSA) and mitoxantrone treatment disrupted the RPA:RAD52 PPI in cells. Furthermore, mitoxantrone reduced radiation-induced foci-formation of RAD52 with no significant activity against RAD51 foci formation. The results indicate that the RPA:RAD52 PPI could be a therapeutic target for HR-deficient cancers. These data also suggest that RAD52 is one of the targets of mitoxantrone and related compounds.

Abstract
CONTEXT Although the roots and stems of Kadsura coccinea (Lem.) A. C. Smith. [Schisandraceae] are herbs and traditional foods in Li nationality, its toxicity remains unclear. OBJECTIVE To study developmental toxicity of K. coccinea consumption and explain underlying mechanisms. MATERIALS AND METHODS Zebrafish were applied to assess LC50 values of hydroethanol extract (KCH) and water extract (KCW) of Kadsura coccinea. In further study, three concentrations groups of KCH (3.75, 7.5 and 15 μg/mL for embryo, 7.5, 15 and 30 μg/mL for larvae) and control group (n = 30) were administered. At specific stages of zebrafish development, spontaneous movement, hatching rate, etc., were measured. Gene expressions related to developmental toxicity were examined. RESULTS The LC50 value of KCH (24 or 45 μg/mL) was lower than KCW (1447 or 2011 μg/mL) in embryos or larvae. The inhibited spontaneous movement (20%), hatching rate (20%), body length (12%) and eye area (30%) were observed after KCH treatment. Moreover, the decreased liver areas (25%) and fluorescence intensity (33%), increased ALT (37%) and AST levels (42%) were found in larvae treated with KCH (30 μg/mL). The increased ROS (89%), MDA concentrations (30%), apoptosis generation (62%) and decreased T-SOD activity (16%) were also observed. The represented genes of developmental hepatotoxicity, oxidative stress and apoptosis in zebrafish were activated after KCH (15 or 30 μg/mL) treatment. DISCUSSION AND CONCLUSIONS These results demonstrate that KCH has developmental toxicity on zebrafish. Our study provides a scientific basis for further research on the toxicity of Kadsura coccinea.

Katoch S, Patial V. Zebrafish: An emerging model system to study liver diseases and related drug discovery. J Appl Toxicol 2020; 41:33-51. [PMID: 32656821 DOI: 10.1002/jat.4031] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Revised: 05/31/2020] [Accepted: 06/11/2020] [Indexed: 01/03/2023]
Abstract
The zebrafish has emerged as a powerful vertebrate model for studying liver-associated disorders. Liver damage is a crucial problem in the process of drug development and zebrafish have proven to be an important tool for the high-throughput screening of drugs for hepatotoxicity. Although the structure of the zebrafish liver differs to that of mammals, the fundamental physiologic processes, genetic mutations and manifestations of pathogenic responses to environmental insults exhibit much similarity. The larval transparency of the zebrafish is a great advantage for real-time imaging in hepatic studies. The zebrafish has a broad spectrum of cytochrome P450 enzymes, which enable the biotransformation of drugs via similar pathways as mammals, including oxidation, reduction and hydrolysis reactions. In the present review, we appraise the various drugs, chemicals and toxins used to study liver toxicity in zebrafish and their similarities to the rodent models for liver-related studies. Interestingly, the zebrafish has also been effectively used to study the pathophysiology of nonalcoholic and alcoholic fatty liver disease. The genetic models of liver disorders and their easy manipulation provide great opportunity in the area of drug development. The zebrafish has proven to be an influential model for the hepatic system due to its invertebrate-like advantages coupled with its vertebrate biology. The present review highlights the pivotal role of zebrafish in bridging the gap between cell-based and mammalian models.

Toxicity Reduction of Euphorbia kansui Stir-Fried with Vinegar Based on Conversion of 3- O-(2' E,4' Z-Decadi-enoyl)-20- O-acetylingenol. Molecules 2019; 24:molecules24203806. [PMID: 31652602 PMCID: PMC6832248 DOI: 10.3390/molecules24203806] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 10/18/2019] [Accepted: 10/20/2019] [Indexed: 11/23/2022] Open
Abstract
The dried roots of Euphorbia kansui S.L.Liou ex S.B.Ho have long been used to treat edema in China. However, the severe toxicity caused by Euphorbia kansui (EK) has seriously restricted its clinical application. Although EK was processed with vinegar to reduce its toxicity, the detailed mechanisms of attenuation in toxicity of EK stir-fried with vinegar (VEK) have not been well delineated. Diterpenoids are the main toxic ingredients of EK, and changes in these after processing may be the underlying mechanism of toxicity attenuation of VEK. 3-O-(2′E,4′Z-decadienoyl)-20-O-acetylingenol (3-O-EZ) is one of the diterpenoids derived from EK, and the content of 3-O-EZ was significantly reduced after processing. This study aims to explore the underlying mechanisms of toxicity reduction of VEK based on the change of 3-O-EZ after processing with vinegar. Based on the chemical structure of 3-O-EZ and the method of processing with vinegar, simulation experiments were carried out to confirm the presence of the product both in EK and VEK and to enrich the product. Then, the difference of peak area of 3-O-EZ and its hydrolysate in EK and VEK were detected by ultra-high-performance liquid chromatography (UPLC). Furthermore, the toxicity effect of 3-O-EZ and its hydrolysate, as well as the underlying mechanism, on zebrafish embryos were investigated. The findings showed that the diterpenoids (3-O-EZ) in EK can convert into less toxic ingenol in VEK after processing with vinegar; meanwhile, the content of ingenol in VEK was higher than that of EK. More interestingly, the ingenol exhibited less toxicity (acute toxicity, developmental toxicity and organic toxicity) than that of 3-O-EZ, and 3-O-EZ could increase malondialdehyde (MDA) content and reduce glutathione (GSH) content; cause embryo oxidative damage by inhibition of the succinate dehydrogenase (SDH) and superoxide dismutase (SOD) activity; and induce inflammation and apoptosis by elevation of IL-2 and IL-8 contents and activation of the caspase-3 and caspase-9 activity. Thus, this study contributes to our understanding of the mechanism of attenuation in toxicity of VEK, and provides the possibility of safe and rational use of EK in clinics.

Abstract
Astrocytes provide nutritional support, regulate inflammation, and perform synaptic functions in the human brain. Although butylated hydroxyanisole (BHA) is a well-known antioxidant, several studies in animals have indicated BHA-mediated liver toxicity, retardation in reproductive organ development and learning, and sleep deficit. However, the specific effects of BHA on human astrocytes and the underlying mechanisms are yet unclear. Here, we investigated the antigrowth effects of BHA through cell cycle arrest and downregulation of regulatory protein expression. The typical cell proliferative signaling pathways, phosphoinositide 3-kinase/protein kinase B and extracellular signal-regulated kinase 1/2, were downregulated in astrocytes after BHA treatment. BHA increased the levels of pro-apoptotic proteins, such as BAX, cytochrome c, cleaved caspase 3, and cleaved caspase 9, and decreased the level of anti-apoptotic protein BCL-XL. It also increased the cytosolic calcium level and the expression of endoplasmic reticulum stress proteins. Treatment with BAPTA-AM, a calcium chelator, attenuated the increased levels of ER stress proteins and cleaved members of the caspase family. We further performed an in vivo evaluation of the neurotoxic effect of BHA on zebrafish embryos and glial fibrillary acidic protein, a representative astrocyte biomarker, in a gfap:eGFP zebrafish transgenic model. Our results provide clear evidence of the potent cytotoxic effects of BHA on human astrocytes, which lead to disruption of the brain and nerve development.
