Canosa IS, Zanitti M, Medesani DA, López Greco LS, Rodríguez EM. Effects of glyphosate on sperm quality of the estuarine crab Neohelice granulata, under the "One Health" perspective. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 948:174879. [PMID: 39047833 DOI: 10.1016/j.scitotenv.2024.174879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 07/11/2024] [Accepted: 07/17/2024] [Indexed: 07/27/2024]
Abstract
This study was aimed at evaluating the effects of the commercial formulation Roundup Ultramax® on sperm mortality and viability, in terms of the capacity of spermatozoids (spz) to trigger the acrosome reaction (AR), using the estuarine crab Neohelice granulata as a model. To this, an in vivo assay comprising 100 days duration was carried out, on a control group and two groups exposed to the formulation (0.01 mg/L and 0.2 mg/L of glyphosate) under controlled conditions of photoperiod, feeding, and temperature. At the end of the assay, the right vas deferens (VD, proximal and middle portion) was dissected, and after homogenizing it in calcium-free saline solution, the acrosome reaction was induced in the phase containing the spz. In each treatment, the percentage of spz with total and partial AR was calculated, as well as that of dead spz. Compared to the control, crabs exposed to the herbicide showed a significant decrease in spz with full AR, together with an increase in the percentage of spz with partial AR. Furthermore, spz mortality was significantly higher in both glyphosate concentrations compared to the control, in a concentration-dependent manner. On the other hand, abnormal spermatophores, showing expanded walls and coalescence, were observed in a significant percentage in the left VD of the groups treated with the herbicide. The results obtained are compared with those from other studies on several invertebrate and vertebrate species that found inhibition of the AR and abnormal sperm, together with inhibition of spermatogenesis, endocrine disruption, and reduced sperm motility by effect of pure glyphosate and/or different glyphosate formulations. In summary, the available evidence highlights the possible impact of glyphosate on sperm quality, in a wide variety of species.

Abstract
A significant advance has been made, especially during the last two decades, in the knowledge of the effects on crustacean species of pollutants proven to be endocrine disruptors in vertebrates. Such effects have been also interpreted in the light of recent studies on crustacean endocrinology. Year after year, the increased number of reports refer to the effects of endocrine disruptors on several processes hormonally controlled. This review is aimed at summarizing and discussing the effects of several kinds of endocrine disruptors on the hormonal control of reproduction (including gonadal growth, sexual differentiation, and offspring development), molting, and intermediate metabolism of crustaceans. A final discussion about the state of the art, as well as the perspective of this toxicological research line is given.

In vivo estrogenicity of glyphosate, its formulations, and AMPA on transgenic zebrafish (Danio rerio) embryos. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 342:123113.

Abstract
In this study, the disrupting effects of glyphosate (GLY), aminomethylphosphonic acid (AMPA), and three glyphosate-based herbicides (GBHs) on vitellogenesis in a non-concentration-dependent manner are reported for the first time in 120 h of acute exposure of zebrafish at environmentally relevant concentrations. GBHs are commonly used worldwide in weed control management. Due to their extensive application, they frequently occur in aquatic ecosystems and may affect various organisms. The active substance GLY and its major by-product, AMPA, are the most thoroughly studied chemicals; however, the adverse effects of the complex formulas of GBHs with diverse and unknown content of co-formulants are still not sufficiently researched. This study focused on the embryotoxicity, sublethal malformations, and estrogenic potency of GLY, AMPA, and four commonly used GBHs on zebrafish embryos using a wild type and an estrogen-sensitive, transgenic zebrafish line (Tg(vtg1:mCherry)). After 120 h of exposition, AMPA did not cause acute toxicity, while the LC50 of GLY was 160 mg/L. The GBHs were more toxic with LC50 values ranging from 31 to 111 GLY active equivalent (a.e.) mg/L. Exposure to 0.35-2.8 mg/L GBHs led to sublethal abnormalities: typical symptoms were structural deformation of the lower jaw and anomalies in the olfactory region. Deformity rates were 10-30% in the treated groups. In vivo, fluorescently expressed vtg1 mCherry protein in embryonic liver was detected by a non-invasive microscopic method indicating estrogenic action through vitellogenin production by GLY, AMPA, and GBHs. To confirm the in vivo findings, RT-qPCR method was performed to determine the levels of the estrogenicity-related vtg1 mRNA. After 120 h of exposure to GLY, AMPA, and three GBHs at a concentration of 0.35 mg/L, the expression of vtg1 gene was significantly up-regulated. Our results highlight the risk that short-term GLY and GBH exposure can cause developmental malformations and disrupt the hormonal balance in zebrafish embryos.

The association between urinary glyphosate and aminomethyl phosphonic acid with biomarkers of oxidative stress among pregnant women in the PROTECT birth cohort study. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 233:113300. [PMID: 35158254 PMCID: PMC8920761 DOI: 10.1016/j.ecoenv.2022.113300] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 02/07/2022] [Accepted: 02/08/2022] [Indexed: 05/03/2023]
Abstract
BACKGROUND Glyphosate is a widely used herbicide in global agriculture. Glyphosate and its primary environmental degradate, aminomethyl phosphonic acid (AMPA), have been shown to disrupt endocrine function and induce oxidative stress in in vitro and animal studies. To our knowledge, these relationships have not been previously characterized in epidemiological settings. Elevated urinary levels of glyphosate and AMPA may be indicative of health effects caused by previous exposure via multiple mechanisms including oxidative stress. METHODS Glyphosate and AMPA were measured in 347 urine samples collected between 16 and 20 weeks gestation and 24-28 weeks gestation from pregnant women in the PROTECT birth cohort. Urinary biomarkers of oxidative stress, comprising 8-isoprostane-prostaglandin-F2α (8-iso-PGF2α), its metabolite 2,3-dinor-5,6-dihydro-15-F2 t-isoprostane (8-isoprostane metabolite) and prostaglandin-F2α (PGF2α), were also measured. Linear mixed effect models assessed the association between exposures and oxidative stress adjusting for maternal age, smoking status, alcohol consumption, household income and specific gravity. Potential nonlinear trends were also assessed using tertiles of glyphosate and AMPA exposure levels. RESULTS No significant differences in exposure or oxidative stress biomarker concentrations were observed between study visits. An interquartile range (IQR) increase in AMPA was associated with 9.5% (95% CI: 0.5-19.3%) higher 8-iso-PGF2α metabolite concentrations. Significant linear trends were also identified when examining tertiles of exposure variables. Compared to the lowest exposure group, the second and third tertiles of AMPA were significantly associated with 12.8% (0.6-26.5%) and 15.2% (1.8-30.3%) higher 8-isoprostane metabolite, respectively. An IQR increase in glyphosate was suggestively associated with 4.7% (-0.9 to 10.7%) higher 8-iso-PGF2α. CONCLUSIONS Urinary concentrations of the main environmental degradate of glyphosate, AMPA, were associated with higher levels of certain oxidative stress biomarkers. Associations with glyphosate reflected similar trends, although findings were not as strong. Additional research is required to better characterize the association between glyphosate exposure and biomarkers of oxidative stress, as well as potential downstream health consequences.

Abstract
Excessively used pesticides in agricultural areas are spilled into aquatic environments, wherein they are suspended or sedimented. Owing to climate change, herbicides are the fastest growing sector of the pesticide industry and are detected in surface water, groundwater, and sediments near agricultural areas. In freshwater, organisms, including mussels, snails, frogs, and fish, are exposed to various types and concentrations of herbicides. Invertebrates are sensitive to herbicide exposure because their defense systems are incomplete. At the top of the food chain in freshwater ecosystems, fish show high bioaccumulation of herbicides. Herbicide exposure causes reproductive toxicity and population declines in freshwater organisms and further contamination of fish used for consumption poses a risk to human health. In addition, it is important to understand how environmental factors are physiologically processed and assess their impacts on reproductive parameters, such as gonadosomatic index and steroid hormone levels. Zebrafish is a good model for examining the effects of herbicides such as atrazine and glyphosate on embryonic development in freshwater fish. This review describes the occurrence and role of herbicides in freshwater environments and their potential implications for the reproduction and embryonic development of freshwater organisms.

Abstract
This study was aimed at evaluating the possible interference of formulated glyphosate to the endocrine control of ovarian growth exerted by progesterone, in the estuarine crab Neohelice granulata. The addition of Roundup Ultramax® (0.2 mg/L of glyphosate in the incubation medium) was able to potentiate the stimulating effect of progesterone on total vitellogenic protein (Vg) content of ovarian pieces from crabs. Moreover, the sole addition of mifepristone (antagonist of progesterone receptors) was able to produce a decrement of the Vg content, which was not reverted by the addition of Roundup. A similar result was confirmed by means of histological analysis, which showed that mifepristone, both alone and in combination with Roundup, inhibited ovarian maturation, while Roundup alone increased it, in terms of a higher proportion of vitellogenic oocytes. We conclude that Roundup could stimulate the progesterone secretion exerted by the ovary and/or could act as a partial agonist of this hormone in the same tissue.

Abstract
This review summarizes the bulk of evidence about the effect of glyphosate, both technical and formulated, on the ovarian maturation of Neohelice granulata female crabs, as well as the effects of glyphosate on sperm production in males of the same species. After long-term in vivo assays, made during the 3-month pre-reproductive period of this species, both formulated and technical glyphosate were able to produce a significant incidence of oocyte reabsorption in the ovary, together with a concomitant decreased of vitellogenin content, at concentrations ranging from 0.2 to 1 mg/L. Despite this, after 32-day in vivo assays, glyphosate stimulated oocyte growth, in terms of a higher percentage of vitellogenic oocytes, suggesting that glyphosate could be acting as an endocrine disruptor. In vitro assays made with isolated ovarian pieces showed a decrease of vitellogenin content, in correlation with lower protein synthesis, although some advance in maturation was observed in the histological analysis. In male crabs exposed in vivo to both technical and formulated glyphosate at 1 mg/L, several reproductive imbalances were noted, such as a significant decrease of the sperm count, abnormal spermatophores, and possible disrupting effects of glyphosate on the androgenic gland.

Abstract
Glyphosate-based herbicides are widely used in global agriculture, and their effects on different non-target animal organisms have been the focus of many toxicological studies. Regarding the potential role of glyphosate-based herbicides as an endocrine disruptor, the present study aims to investigate the effects of the herbicide Roundup WG® (RWG) on female reproduction, specifically on the ovarian maturation of Danio rerio. Adult females were exposed to low concentrations of RWG (0.065, 0.65, and 6.5 mg L-1) for 15 days, and then the ovaries were submitted to structural and morphometric procedures, accompanied by analysis of the vitellin protein content. Our results showed an increase of initial ovarian follicle numbers, decrease of late ovarian follicles, and smaller diameter of ovarian follicles in fish exposed to 0.065 and 6.5 mg L-1. The thickness of vitelline envelope was reduced, and the vitellin protein content was increased in the ovarian follicle in the two highest concentrations. Ultrastructural changes in the ovarian follicular component were evident and expressed by the cell index; vacuolization in follicular cells, increase of perivitelline space, and impaired mitochondria in oocytes were observed. Therefore, RWG adversely affects the ovarian maturation in D. rerio, and these changes can lead to reproductive toxicity, compromising population dynamics.

Abstract
Glyphosate-based herbicides (GBHs) occur in aquatic ecosystems at concentrations of hundreds of micrograms per liter. As formulation adjuvants are suspected to be endocrine-disrupting chemicals, we assessed the effects of the recent GBH formulation Roundup® Power 2.0 on vitellogenin (VTG) in Mytilus galloprovincialis. Mussels were exposed for 7, 14, and 21 days to two concentrations of the commercial formulation, corresponding to 100 and 1000 μg/L of glyphosate. The expression of the vtg gene in gonads of females and males, as well as the levels of alkali labile phosphates (ALP) in gonads and non-gonadal tissues from the two sexes were measured. No significant alterations were observed in vtg expression values during the exposure. Conversely, a significant reduction in gonadal ALP levels was observed in females exposed for 21 days and in males exposed for 7 days. In addition, ALP levels increased significantly in gonads from males exposed for 21 days to the two concentrations of Roundup®. As for non-gonadal tissues, ALP levels did not change significantly in females, whereas ALP levels decreased significantly in non-gonadal tissues from males exposed for 21 days to the lowest concentration tested. An overall statistically significant difference in ALP levels was found between females and males. Although preliminary, our study suggests that GBH can affect reproduction-related parameters in mussels.

The Effects of Glyphosate and Its Commercial Formulations to Marine Invertebrates: A Review. JOURNAL OF MARINE SCIENCE AND ENGINEERING 2020.

Abstract
Glyphosate is the active ingredient of numerous commercial formulations of herbicides applied in different sectors, from agriculture to aquaculture. Due to its widespread use around the world, relatively high concentrations of glyphosate have been detected in soil and aquatic environments. The presence of glyphosate in aquatic ecosystems has aroused the attention of researchers because of its potential negative effects on living organisms, both animals and plants. In this context, this review intends to summarize results of studies aimed at evaluating the effects of glyphosate (both as active ingredient and component of commercial formulations) on marine invertebrates. Generally, data obtained in acute toxicity tests indicate that glyphosate and its commercial formulations are lethal at high concentrations (not environmentally realistic), whereas results of long-lasting experiments indicate that glyphosate can markedly affect biological responses of marine invertebrates. Consequently, more efforts should be addressed at evaluating chronic or sub-chronic effects of such substances to marine invertebrate species.

Abstract
Atrazine is currently one of the most used herbicides worldwide. We tested the possible effect of the widely used herbicide atrazine on the endocrine control of ovarian growth exerted by the neurohormones secreted at the eyestalk of the estuarine crab Neohelice granulata. For this, both in vivo and in vitro assays were carried out. The in vivo assay comprised the exposure for 1 month to 3 mg/L of a commercial formulation containing 90% of atrazine as active ingredient (Gesaprim 90 WDG®, Syngenta) on three categories of females: intact, ablated of one eyestalk, and ablated of both eyestalks. At the end of the assay, only the intact females showed a significant (p < 0.05) decrease in both content of vitellogenic ovarian proteins and proportion of vitellogenic oocytes, compared to a concurrent control. The results of the in vitro incubation of ovarian pieces with the eventual addition to the incubation medium of eyestalk tissue and/or atrazine at 3 mg/L showed a significant (p < 0.05) decrease in the proportion of vitellogenic oocytes only when atrazine and eyestalk tissue were added. Taken together, these results strongly suggest that the assayed atrazine formulation may act as an endocrine disruptor at the eyestalk level, by altering the normal secretion of some eyestalk hormone, therefore inhibiting ovarian growth.

Abstract
The effect of glyphosate, both pure and formulated (Roundup Ultramax®), was evaluated on males of the estuarine crab Neohelice granulata, by means of both in vivo and in vitro assays. The in vivo assays comprised the exposure for 30 d to 1 mg/L of the herbicide, until finally assessing weight gain, levels of energy reserves, sperm number per spermatophore, proportion of abnormal spermatophores, and sperm viability. At the end of this assay, significant (p < 0.05) decrease in weight gain and muscle protein levels was detected by effect of both pure and formulated glyphosate. In spermatophores from the vas deferens, a significant (p < 0.05) decrease of the sperm count was observed by effect of Roundup, while a significant incidence (p < 0.05) of abnormal spermatophores was observed either with glyphosate or with Roundup treatment. No changes were seen in the spermatophore area or in vas deferens secretions. Since no sperm mortality was induced by the formulated herbicide, we propose a probable inhibiting effect on spermatogenesis might explain the observed sperm count decrease. In this sense, an in vitro assay was designed by incubating testes and vasa deferentia with Roundup, in order to corroborate the possible interference of glyphosate with the secretion of the androgenic gland hormone that controls the spermatogenesis, in the presence or absence of the androgenic gland. Although the herbicide per se was able to reduce the sperm count to some extent, the increase in the number of spermatozoa/spermatophore produced by the co-incubation with the androgenic gland was completely reverted by the addition of Roundup (1 mg/L of glyphosate a.e.), suggesting that an inhibition on the secretion and/or transduction of the androgenic gland hormone could be taking place.

Histopathological and ultrastructural indices for the assessment of glyphosate-based herbicide cytotoxicity in decapod crustacean hepatopancreas. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2019; 210:207-214.

Abstract
Glyphosate-based herbicides (GBH), including Roundup, are the most widely used pesticides in the world. Glyphosate residues have been detected in surface and groundwater, in food, and in human blood and urine. The effects of this herbicide on different levels of biological organization are an important concern that needs to be investigated. In general, the toxicity of GBH in invertebrates is poorly understood, and it is the motivation of this study. Thus, the aim of this study was to evaluate cellular responses of the hepatopancreas, an organ involved in the detoxification process in invertebrates, after exposure to environmentally relevant concentrations of GBH, using prawn Macrobrachium potiuna as a model. Prawns were exposed to three concentrations of GBH (0.0065, 0.065 and 0.28 mg L-1) for 7 or 14 days. Alterations in the morphology of the hepatopancreas and in subcellular components of R cells, which are responsible for the detoxification process, were analyzed, and an index for subcellular alterations was standardized. GBH exposure induced tissue commitments on the hepatopancreas, as well as important impairments of R cells that could compromise the normal functioning of the cells, especially in the detoxification processes. The major cellular impairments were intense vacuolization, dilatation of the cisterns of the rough endoplasmic reticulum and Golgi bodies, increase of perinuclear space, necrosis, concentric membrane formation and mitochondria crest loss. Our data contribute to the knowledge of the cytotoxic effects of low GBH concentrations on aquatic invertebrates, specifically their effects on the hepatopancreas, an important organ for the metabolism of crustaceans. These results also indicate that concentrations considered safe by regulatory agencies should be reviewed to minimize the effects on non-target organisms. This study also contributes to the standardization of an ultrastructure index for the assessment of GBH in palaemonids, which could be used for the assessment of contaminants in crustaceans and other species with hepatopancreas.

Abstract
Glyphosate is the active ingredient of the commercial formulation Roundup®, which is used worldwide. This study aimed to investigate the toxic effects of pure glyphosate or Roundup® on pregnant mice and their fetuses during pregnancy. From gestation days (GDs) 1-19, ICR mice were orally administered distilled water, 0.5% glyphosate solution or 0.5%-glyphosate Roundup® solution. The ovaries and serum were collected at GD19. The results showed decreases in body weight gain and, ovary and liver weight in glyphosate-treated mice. Additionally, histopathological alterations in the ovary including increased atretic follicles, interstitial fibrosis and decreased mature follicles were observed in the groups treated with glyphosate. The serum concentrations of both progesterone and estrogen were markedly altered after glyphosate exposure, and there were also changes in the expression of GnRH, LHR, FSHR, 3β-HSD and Cyp19a1 genes at the hypothalamic-pituitary-ovarian axis. Furthermore, oxidative stress was observed in the treated mice, increasing the activity of T-AOC, CAT and GSH-Px, as well as the MDA content in both the serum and ovary. With regard to litters, the sex ratio was significantly altered by pure glyphosate. These results show that glyphosate is able to cause several effects on pregnant mice, such as ovarian failure, interference with hormone secretion by affecting the steroidogenesis-related gene expression, and oxidative stress. The sex ratio of litters was also influenced by prenatal exposure to pure glyphosate.
