Battistoni M, Metruccio F, Di Renzo F, Moretto A, Bacchetta R, Menegola E. Effects of combined exposure to two bisphenol plasticizers (BPA and BPB) on Xenopus laevis development. Reprod Toxicol 2024; 128:108614. [PMID: 38866257 DOI: 10.1016/j.reprotox.2024.108614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 05/20/2024] [Accepted: 05/21/2024] [Indexed: 06/14/2024]
Abstract
Due to its endocrine disruptive activity, the plastic additive Bisphenol A (BPA) is classified as substance of very high concern (EU ECHA 2017). A correlation between environmental exposure to BPA and congenital defects has been described in humans and in experimental species including the amphibian Xenopus laevis, where severe branchial defects were associated to lethality. The exposure of X. laevis embryos to the BPA analogue bisphenol B (BPB) was recently linked to similar teratogenic effects, with BPB having relative potency about 3 times higher than BPA. The combined BPA-BPB exposure is realistic as both BPA and BPB are detected in human samples and environment. Limited experimental data are available on the combined developmental toxicity of BPA and BPB. The aim of the present work is to evaluate the effects of BPA and BPB mixture in the X. laevis development model, using R-FETAX procedure. The exposure was limited to the first day of development (corresponding to the phylotypic developmental period, common to all vertebrates). Samples were monitored for lethal effects during the full six-day test period and the external morphology was evaluated at the end of the test. Mixture effects were described by modelling, using the PROAST software package. Overall data modelling showed that dose-addiction could not be rejected, suggesting a health concern for co-exposure.

Abstract
In this presented study, the aim was to investigate the toxic effects of bisphenol S (BPS), one of the bisphenol A analogues, on the thyroid glands of male Wistar albino rats. Toward this aim, the rats (n = 28) were given a vehicle (control) or BPS at 3 different doses, comprising 20, 100, and 500 mg/kg of body weight (bw) via oral gavage for 28 days. According to the results, BPS led to numerous histopathological changes in the thyroid tissue. The average proliferation index values among the thyroid follicular cells (TFCs) displayed increases in all of the BPS groups, and significant differences were observed in the BPS-20 and BPS-100 groups. The average apoptotic index values in the TFCs were increased significantly in the BPS-500 group. The serum thyroid-stimulating hormone and serum free thyroxine levels did not show significant changes after exposure to BPS; however, the serum free triiodothyronine levels displayed significant decreases in all 3 of the BPS groups. BPS was determined to cause significant increases in the antioxidant enzyme activities of catalase, superoxide dismutase, glutathione-S-transferase, glutathione peroxidase, as well as a significantly decreased content of reduced glutathione. The malondialdehyde level in the thyroid tissue was elevated significantly in the BPS-500 group. The data obtained herein revealed that BPS has thyroid-disrupting potential based on structural changes, follicle cell responses, and biochemical alterations including a decreased serum free triiodothyronine level and increased oxidative stress.

Abstract
The critical developmental stages of the embryo are strongly influenced by the dietary composition of the mother. Acrylamide is a food contaminant that can form in carbohydrate-rich foods that are heat-treated. The aim of this study was to investigate the toxicity of a relatively low dose of acrylamide on the development of the neural tube in the early stage chick embryos. Specific pathogen-free fertilized eggs (n = 100) were treated with acrylamide (0.1, 0.5, 2.5, 12.5 mg/kg) between 28-30th hours of incubation and dissected at 48th hours. In addition to morphological and histopathological examinations, proliferating cell nuclear antigen (PCNA) and caspase 3 were analyzed immunohistochemically. The brain and reproductive expression gene (BRE) was analyzed by RT-PCR. Acrylamide exposure had a negative effect on neural tube status even at a very low dose (0.1 mg/kg) (p < 0.05). Doses of 0.5 mg/kg and above caused a delay in neural tube development (p < 0.05). Crown-rump length and somite count decreased dose-dependently, while this decrease was not significant in the very low dose group (p > 0.05), which was most pronounced at doses of 2.5 and 12.5 mg/kg (p < 0.001). Acrylamide exposure dose-dependently decreased PCNA and increased caspase 3, with this change being significant at doses of 0.5 mg/kg and above (p < 0.001). BRE was downregulated at all acrylamide exposures except in the very low dose group (0.1 mg/kg). In conclusion, we find that acrylamide exposure (at 0.5 mg/kg and above) in post-gastrulation delays neural tube closure in chicken embryos by suppressing proliferation and apoptosis induction and downregulating BRE gene expression.

Food Chem Toxicol 2024; 190:114787. [PMID: 38838754 DOI: 10.1016/j.fct.2024.114787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 04/26/2024] [Accepted: 06/01/2024] [Indexed: 06/07/2024]
Abstract
Lignin-derivable bisguaiacols/bissyringols are viable alternatives to commercial bisphenols; however, many bisguaiacols/bissyringols (e.g., bisguaiacol F [BGF]) have unsubstituted bridging carbons between the aromatic rings, making them more structurally similar to bisphenol F (BPF) than bisphenol A (BPA) - both of which are suspected endocrine disruptors. Herein, we investigated the estrogenic activity (EA) and developmental toxicity of dimethyl-substituted bridging carbon-based lignin-derivable bisphenols (bisguaiacol A [BGA] and bissyringol A [BSA]). Notably, BSA showed undetectable EA at seven test concentrations (from 10-12 M to 10-6 M) in the MCF-7 cell proliferation assay, whereas BPA had detectable EA at five concentrations (from 10-10 M to 10-6 M). In silico results indicated that BSA had the lowest binding affinity with estrogen receptors. Moreover, in vivo chicken embryonic assay results revealed that lignin-derivable monomers had minimal developmental toxicity vs. BPA at environmentally relevant test concentrations (8.7-116 μg/kg). Additionally, all lignin-derivable compounds showed significantly lower expression fold changes (from ∼1.81 to ∼4.41) in chicken fetal liver tests for an estrogen-response gene (apolipoprotein II) in comparison to BPA (fold change of ∼11.51), which was indicative of significantly reduced estrogenic response. Altogether, the methoxy substituents on lignin-derivable bisphenols appeared to be a positive factor in reducing the EA of BPA alternatives.

Abstract
OBJECTIVE In this study, we aimed to evaluate BPA levels in the maternal serum and amniotic fluid of patients diagnosed with NTD. In addition, we wanted to investigate the relationship between neurodevelopmental defects, such as neural tube defects (NTD), and BPA levels. STUDY DESIGN This prospective observational study was carried out at Bursa Yüksek İhtisas Training and Research Hospital between April 15, 2021, and April 15, 2022. The study consisted of 92 patients between the ages of 18-45 who had an amniocentesis at 15-22 weeks of gestation. The patients were divided into two groups according to the indications of amniocentesis. Group 1 contained the patients with abnormal maternal serum screening results or cell-free DNA results and abnormal ultrasonography findings (45 patients). Group 2 contained the patients with a pre-diagnosis of NTD (47 patients). The first 5 cc fluids and maternal serum samples taken during the amniocentesis procedure of all patients were delivered to the biochemistry laboratory. The BPA values between groups were compared. RESULTS A statistically significant difference was found between the two groups in terms of amniotic fluid BPA levels (36.66 (19.00:82.00) and 39.62 (19.02-73.87)) and maternal blood BPA levels (22.26 (12.60-228) and 47.81 (12.89-228.39)). In cases with NTD, amniotic fluid BPA levels and maternal blood BPA levels were significantly higher than the control group. When AUC values were compared, the AFP numerical value was higher than the amniotic fluid and maternal blood BPA levels. CONCLUSION Plastic, which is indispensable for modern life, may negatively affect fetal development in intrauterine life. The data in this study says that high maternal blood BPA may be associated with NTD.

Abstract
Teratology, the study of congenital anomalies and their causative factors intersects with developmental and reproductive toxicology, employing innovative methodologies. Evaluating the potential impacts of teratogens on fetal development and assessing human risk is an essential prerequisite in preclinical research. The chicken embryo model has emerged as a powerful tool for understanding human embryonic development due to its remarkable resemblance to humans. This model offers a unique platform for investigating the effects of substances on developing embryos, employing techniques such as ex ovo and in ovo assays, chorioallantoic membrane assays, and embryonic culture techniques. The advantages of chicken embryonic models include their accessibility, cost-effectiveness, and biological relevance to vertebrate development, enabling efficient screening of developmental toxicity. However, these models have limitations, such as the absence of a placenta and maternal metabolism, impacting the study of nutrient exchange and hormone regulation. Despite these limitations, understanding and mitigating the challenges posed by the absence of a placenta and maternal metabolism are critical for maximizing the utility of the chick embryo model in developmental toxicity testing. Indeed, the insights gained from utilizing these assays and their constraints can significantly contribute to our understanding of the developmental impacts of various agents. This review underscores the utilization of chicken embryonic models in developmental toxicity testing, highlighting their advantages and disadvantages by addressing the challenges posed by their physiological differences from mammalian systems.

Abstract
Sugammadex is a new generation drug that has led to significant changes in the practice of anesthesia. However, its effects on fetal development are not yet fully known. The aim of this study is to investigate the teratogenic effects of sugammadex on neural tube and embryonic development in early chick embryos. In this study, 50 0-day fertile specific non-pathogenic (SPF) eggs were used. Fifty eggs were divided into 5 different groups, each consisting of 10 pieces. While no substance was given to the control group at the 28th hour of the study, 4 different doses of sugammadex were administered to the experimental groups, respectively 2, 4, 8, 16 mg/kg. Cranio-caudal lengths of embryos, somite numbers, average number of argyrophilic nucleolar regulatory regions (AgNOR) per nucleus, total AgNOR area/total nuclear area (TAA/NA) ratios, Caspase-3 H-Score results, and presence of neural tube defect were compared among the groups. While the mean cranio-caudal lengths, somite counts, TAA/NA ratios and AgNOR counts of the embryos were found to be statistically significantly lower than the control group, Caspase-3 H-Score mean results were found to be significantly higher (p < .05). In addition, it was observed that there was an increase in neural tube patency and developmental delay. As a result, sugammadex crossing the placenta was revealed to increase the release of proapopitotic molecules and disrupt the developmental stages of embryos. Thus, it was determined that sugammadex in increased developmental delay and incidence of neural tube defects in early chick embryos with increased dose dependent. Despite these results, the effects of sugammadex on fetal development in in vivo and in vitro environments should be studied with further studies. RESEARCH HIGHLIGHTS: Sugammadex is a new generation drug that has led to significant changes in the practice of anesthesia. However, its effects on fetal development are not yet fully known. It has been observed that different doses of sugammadex increase the risk of neural tube defect development on chick embryos and slow the embryo development in a dose-dependent manner.

Abstract
Bisphenol A (BPA) is a plastic additive with endocrine disruptive activity, classified in 2017 by EU ECHA as substance of very high concern. A correlation between environmental exposure to BPA and congenital defects has been described in humans and in experimental species, including the amphibian Xenopus laevis. Among BPA analogues, bisphenol B (BPB) is used as alternative in different not-EU countries, including US, but seems to share with BPA its endocrine disruptor properties. Aim of the present work is the evaluation of the effects of BPB versus BPA exposure in a X. laevis developmental model. A windowed exposure (R-FETAX method) was applied covering the developmental phylotypic period (teratogenicity window), or the late tailbud stages (neuro-behavioural toxicity window, corresponding to the spontaneous swimming acquisition period). Samples were monitored for lethal effects during the full test period. External morphology evaluation and deglutition functional test were applied in any group. Abnormal tadpoles were also processed for cartilage staining. In groups exposed during neuro-behavioural toxicity window the swimming test was also applied. Lethality and malformations were obtained only in samples exposed during the teratogenicity window; these data were modelled using PROAST software and BPB relative potency resulted about 3 times higher than BPA. The day-by-day evaluation revealed that lethality was correlated to embryonic abnormal development of gills and apoptosis in gill primordia. Teratogenicity was never detected in groups exposed during the neuro-behavioural toxicity window, where some significant neuro-behavioural deficits were detected in tadpoles exposed to the highest tested concentrations of BPA and BPB.

Abstract
Nausea and vomiting during pregnancy are common problems and prolonged pharmacological treatment often is needed; however, the teratogenic effects of anti-emetic drugs on neural tube (NT) development are not clear. We investigated the effects of different doses of metoclopramide on NT development in 48 and 72 h chick embryos using an argyrophilic nucleolar organizing region (AgNOR) staining method. We used 150 fertile, specific pathogen-free eggs incubated for 28 h, then randomly divided into five equal groups: group A, sham control was administered 0.9% saline; groups B - E were administered 0.15 mg/egg, 0.3 mg/egg, 0.6 mg/egg and 1.2 mg/egg, respectively. Half of the eggs in each group were taken from the incubator at 48 h incubation and the other half at 72 h incubation. After incubation, eggs were opened, embryos were dissected from their membranes, fixed with 10% formalin and examined by light microscopy. The NT status, i.e., open or closed, and somite number, crown-rump length, morphological features and gross developmental abnormalities were recorded. Excised embryos were sectioned and stained using hematoxylin and eosin or the AgNOR procedure and examined for morphology and histopathology. Delayed NT closure was observed in all 48 h drug exposed embryos, but in the 72 h groups, this occurred only in high-dose groups. Somite number was reduced significantly in groups C - E compared to the control group. Crown-rump length was decreased in both 48 and 72 h embryos. We found a decreased total AgNOR area:nuclear area ratio in 48 and 72 h embryos of all experimental groups. We found that metoclopramide delayed NT closure in chick embryos in a dose-dependent manner.

Abstract
Monosodium glutamate (MSG) is a popular flavor enhancer largely used in the food industry. Although numerous studies have reported the neurotoxic effects of MSG on humans and animals, there is limited information about how it affects embryonic brain development. Thus, this study aimed to determine the effects of in ovo administered MSG on embryonic brain development in chickens. For this purpose, 410 fertilized chicken eggs were divided into 5 groups as control, distilled water, 0.12, 0.6 and 1.2 mg/g egg MSG, and injections were performed via the egg yolk. On days 15, 18, and 21 of the incubation period, brain tissue samples were taken from all embryos and chicks. The mortality rates of MSG-treated groups were significantly higher than those of the control and distilled water groups. The MSG-treated groups showed embryonic growth retardation and various structural abnormalities such as abdominal hernia, unilateral anophthalmia, hemorrhage, brain malformation, and the curling of legs and fingers. The relative embryo and body weights of the MSG-treated groups were significantly lower than those of the control group on incubation days 18 and 21. Histopathological evaluations revealed that MSG caused histopathological changes such as necrosis, neuronophagia, and gliosis in brain on incubation days 15, 18, and 21. There was a significant increase in the number of necrotic neurons in the MSG-treated groups compared to the control and distilled water groups in the hyperpallium, optic tectum and hippocampus regions. Proliferating cell nuclear antigen (PCNA) positive cells in brain were found in the hyperpallium, optic tectum, and hippocampus regions; there were more PCNA(+) immunoreactive cells in MSG-treated groups than in control and distilled water groups. In conclusion, it was determined that in ovo MSG administered could adversely affect embryonic growth and development in addition to causing necrosis in the neurons in the developing brain.

Abstract
Objective: Biperiden (BPD) is an anticholinergic agent that acts both centrally and peripherally. It is used to counteract both extrapyramidal side effects of neuroleptic treatment and symptoms of Parkinson’s disease in clinical practice. Current study was layout to determine the potential toxic effect of different doses of Biperiden on neural tube closure in 48 hour chick embryos. Methods: Sixty fertilized eggs were used in the study. All eggs were placed in the incubator and divided into four groups (15 eggs in each); control, BPD 1, BPA 2 and BPD 3. At 28 hr of incubation, three different doses of biperiden were administered subblastodermically. At the end of 48 hr of incubation, all eggs were opened and embryos were dissected and evaluated morphologically and histopathologically. Results: According to these results, the mean crown-rump length and somite number tended to decrease proportionally with the dose. As the dose increases, the number of open neural tube and undeveloped embryos in the experimental groups also increases. There was also a significant difference between the groups in terms of Hamburger-Hamilton stages of embryos evaluated according to the number of somite. Embryos in the control, BPD 1 and BPD 2 groups were observed at stage 13, and those in the BPD 3 group were observed at stage 12. Conclusion: These results showed that Biperiden even in the low dose has teratogenicity on neural tube closure in early chick embryos. The somite numbers and crown-rump length were decreased depending on the dose and Biperiden caused developmental retardation in high doses.

Abstract
Monosodium glutamate (MSG) is a flavor enhancer commonly used in modern nutrition. In this study, it was aimed to determine the effect of in ovo administered MSG on the embryonic development of thymus, bursa of Fabricius, and percentages of alpha-naphthyl acetate esterase (ANAE) positive lymphocyte by using histological, histometrical, and enzyme histochemical methods in chickens. For this purpose, 410 fertile eggs were used. The eggs were then divided into five groups: group 1 (control group, n = 40 eggs), group 2 (distilled water-injected group, n = 62 eggs), group 3 (0.12 mg/g egg MSG-injected group, n = 80 eggs), group 4 (0.6 mg/g egg MSG-injected group, n = 90 eggs), and group 5 (1.2 mg/g egg MSG-injected group, n = 138 eggs), and injections were performed via the egg yolk. On the 18th and 21st days of the incubation, the eggs were randomly opened from each group until six live embryos were obtained. The embryos of each group were sacrificed by decapitation, and blood, thymus, and bursa of Fabricius tissue samples were taken from the obtained embryos. The MSG-treated groups were found to be retarded embryonic development of thymus and bursa of Fabricius tissue compared to the control and distilled water groups. MSG treatment also resulted in reduced lymphoid follicles count and follicle diameters in bursa of Fabricius (P < 0.05). The percentage of peripheral blood ANAE positive lymphocytes was significantly lower in the MSG-treated groups than in the control and distilled water groups (P < 0.05). In conclusion, it has been found that in ovo administered MSG can adversely affect the embryonic development of thymus and bursa of Fabricius and decrease percentage of ANAE positive lymphocyte.

Teratogenicity and toxicity of the new BPA alternative TMBPF, and BPA, BPS, and BPAF in chick embryonic development. Curr Res Toxicol 2021; 2:399-410. [PMID: 34901887 PMCID: PMC8639335 DOI: 10.1016/j.crtox.2021.11.001] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 11/11/2021] [Accepted: 11/15/2021] [Indexed: 11/21/2022] Open
Abstract
Bisphenol A (BPA) is a widely known, yet controversial reproductive toxin, capable of inducing reproductive, developmental, and somatic growth defects across species. Due to scientific findings and public concern, companies have developed BPA alternatives remarkably similar to BPA. However, these alternatives have had much less testing and oversight, yet they are already being mass-produced and used across industries from plastics to food-contact coatings. The newest one, tetramethyl bisphenol F (TMBPF), is the least well-studied and has never been investigated in embryological models, however it continues to be mass produced and found in various products. Here, we used the chicken embryotoxicity screening test to compare the toxicities and potencies of several BPA analogs including TMBPF. We exposed developing chicken (Gallus gallus domesticus) embryos in ovo, from embryonic day 5 to 12 (E5-12), to increasing concentrations of BPA, bisphenol S (BPS), bisphenol AF (BPAF), and TMBPF, from 0.003 to 30 μM, and analyzed their developmental and toxic effects. The bisphenols significantly impaired development, growth, and survival in a dose-dependent manner, even at low, environmentally relevant concentrations of 3-30 nM. There was severely reduced growth and developmental delay, with exposed embryos averaging half the size and weight of control vehicle-treated embryos. The most common and severe dysmorphologies were craniofacial, eye, gastrointestinal, and body pigmentation abnormalities. The bisphenols caused dose-dependent toxicity with the lowest LC50s (lethal concentration with 50% survival) ever demonstrated in chick embryos, at 0.83-2.92 μM. Notably, TMBPF was the second-most toxic and teratogenic of all chemicals tested (rank order of BPAF > TMBPF > BPS > BPA). These results underscore the adverse effects of BPA replacements on early embryo development and may have implications for reproductive health and disease across species, including pregnancy exposures in humans.

Abstract
Bisphenol A (BPA), one of the endocrine disrupting chemicals, is the object of great concern because of its widespread use throughout the world. In this study, it was aimed to determine the effects of in ovo administrated BPA on the bursa of Fabricius and percentage of acid phosphatase positive lymphocyte in peripheral blood by means of histological and enzyme histochemical methods. For this purpose, 310 fertile eggs of Isa Brown laying parent stock were used. The eggs were divided into 5 groups as control, vehicle control, 50, 100, and 250μg/egg BPA. At days 13, 18, and 21 of incubation, eggs were opened until 10 living embryos were obtained from each group. Tissue samples were taken from the obtained embryos and processed for enzyme histochemical methods in addition to routine histological techniques. It was observed that, in BPA-treated groups, embryonic development of bursa of Fabricius was retarded. It was also indicated that the percentage of peripheral blood ACP-ase positive lymphocytes was significantly decreased. These results suggested that a limited maternal transfer of BPA into the eggs might be lead to immunosuppression in chicks.

Abstract
OBJECTIVES The aim of this study was to determine of the effects of in ovo administered BPA on embryonic development of the tibial growth plate using histological methods in chickens. METHODS Three hundred and ten fertile eggs of Isa Brown laying parent stock were divided into five groups as untreated control, vehicle-injected control, 50, 100, and 250 μg/egg BPA. At the 13th, 18th, and 21st days of incubation, eggs were randomly opened from each group until 10 live embryos were obtained. Embryos were weighed and crown-rump length was measured. Tibial tissue samples were taken from embryos. Tibia weight, relative tibia weight and tibia length were determined. Tissue samples were fixed in 10% buffered formalin solution. Sections were stained with Safranin O staining methods and zones in the growth plate were measured. Also, proliferating cell nuclear antigen (PCNA) was stained immunohistochemically. RESULTS The mortality in the BPA treated groups was higher than untreated control group. The results have revealed that mean relative embryo weights, crown-rump length, mean tibia weight, relative tibia weight, and tibia length of BPA treated groups were significantly lower when compared to the untreated control and vehicle-injected control groups. Also, proliferative zone get significantly narrowed, whereas the transitional and hypertrophic zone thickened and PCNA positive chondrocytes increased in growth plate of BPA treated groups. CONCLUSION These results have suggested that developmental exposure to BPA adversely affected development of the tibial growth plate.

Abstract
BACKGROUND Neural tube defects are among the most frequent congenital abnormalities of the central nervous system. Progression of neural tube deficits is affected by hereditary predilection and environmental determinants. Pethidine (meperidine) is a fast and powerful opioid analgesic in U.S. Food and Drug Administration category C. There are reports about developmental anomalies due to this medication. The aim of this study was to investigate the effects of different doses of pethidine hydrochloride on neural tube development in a chick embryo model resembling the first month of vertebral growth in mammals. METHODS Seventy-five specific pathogen-free eggs were incubated for 28 hours and divided into 5 groups (including the control group), each consisting of 15 eggs. Pethidine hydrochloride was administered sub-blastodermically with a Hamilton microinjector in 4 different doses. Incubation was continued until the end of the 48th hour. Subsequently, all eggs were opened, and embryos were cut from the embryonic membranes and evaluated morphologically, genetically, and histopathologically. RESULTS Crown-rump length, somite numbers, and silver-stained nucleolar organizer region (AgNOR) number averages, and total AgNOR/nuclear area ratios decreased in a dose-dependent manner. Examination of neural tube closure revealed statistically significant differences in all experimental groups (P<0.05). Messenger RNA levels of the BRE gene were decreased in pethidine hydrochloride-exposed embryos compared with the control group. Although this downregulation was not statistically significant, this decrease was striking with a 0.422-fold change in the fifth group. CONCLUSIONS We demonstrated that pethidine hydrochloride affects neuronal development in chicken embryos. The teratogenic mechanism of pethidine hydrochloride is unclear; therefore, further investigation is required.
