The herbicide 2,4-dichlorophenoxyacetic acid induces pancreatic β-cell death via oxidative stress-activated AMPKα signal downstream-regulated apoptotic pathway. Toxicol Lett 2025; 405:16-29. [PMID: 39921193 DOI: 10.1016/j.toxlet.2025.01.009] [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: 07/19/2024] [Revised: 01/07/2025] [Accepted: 01/31/2025] [Indexed: 02/10/2025]
Abstract
2,4-Dichlorophenoxyacetic acid (2,4-D) is one of commonly and widely used organic herbicides in agriculture. It has been reported that 2,4-D can induce adverse effects in mammalian cells. Epidemiological and animal studies have indicated that exposure to 2,4-D is associated with poorer glycemic control and impaired pancreatic β-cell function. However, limited information is available on 2,4-D-induced toxicological effects in β-cells, with the underlying toxicological mechanisms remains unclear. Herein, our results showed that 2,4-D exposure (30-500 μg/mL) significantly reduced cell viability, induced mitochondria dysfunction (including the mitochondrial membrane potential (MMP) loss, the increase in cytosolic cytochrome c release, and the change in Bcl-2 and Bax protein expression), and triggered apoptotic events (including the increased population of apoptotic cells, caspase-3 activity, and caspase-3/-7 and PAPR activation) in RIN-m5F β-cells, accompanied with insulin secretion inhibition. Exposure of cells to 2,4-D could also evoke JNK, ERK1/2, p38, and AMP-activated protein kinase (AMPK)α activation as well as reactive oxygen species (ROS) generation. Pretreatment of cells with compound C (an AMPK inhibitor) and the antioxidantN-acetylcysteine (NAC), but not that SP600125/PD98059/SB203580 (the inhibitors of JNK/ERK/p38, respectively), obviously attenuated the 2,4-D-triggered AMPKα phosphorylation, MMP loss, apoptotic events, and insulin secretion dysfunction,as similar effects with the transfection with AMPKα1-specific siRNA. Of note, buffering the ROS production with NAC obviously prevented the 2,4-D-induced ROS generation as well as AMPKα activation, but the either compound C and AMPKα1-specific siRNA transfection could not effectively reduce 2,4-D-induced ROS generation. Collectively, these findings indicate that the induction of oxidative stress-activated AMPKα signaling is a crucial mechanism underlying 2,4-D-triggered mitochondria-dependent apoptosis, ultimately leading to β-cell death.

Sci Rep 2024; 14:31674. [PMID: 39738374 PMCID: PMC11686124 DOI: 10.1038/s41598-024-81586-6] [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: 08/07/2024] [Accepted: 11/27/2024] [Indexed: 01/02/2025] Open
Abstract
The application of pesticides may adversely impact a variety of non-target organisms. The use of side-effect-free herbal remedies to protect against the toxicity of harmful pesticides such as etoxazole has gained attention in recent times. The current study aimed to reveal the potential mitigating efficacy of Achillea millefolium L. extract against etoxazole toxicity in Allium cepa L. A. cepa bulbs in the control group were applied with tap water, while bulbs in the treatment groups were applied with etoxazole at dose of 0.5 m/L and two different doses of A. millefolium extract (200 mg/L and 400 mg/L). The impact of the treatments on certain parameters was evaluated. The molecular docking analysis was employed to investigate the potential interactions of etoxazole with DNA species, DNA topoisomerases, tubulin proteins, glutamate-1-semialdehyde aminotransferase, and protochlorophyllide reductase. The phenolic profile of A. millefolium was assessed. Etoxazole exposure reduced rooting percentage, root length, weight gain, mitotic index, and levels of chlorophyll a and chlorophyll b. Conversely, etoxazole treatment led to an increase in chromosomal aberrations and micronuclei occurrence. The most frequently observed chromosomal aberrations induced by etoxazole, which serve as bioindicators of genotoxicity, were fragment, vagrant chromosome, sticky chromosome, unequal chromatin distribution, bridge, reverse polarization, and vacuolated nucleus. The levels of malondialdehyde and antioxidant enzyme (superoxide dismutase and catalase) activities were also elevated. Epidermis cell damage, flattened cell nucleus, thickened cortex cell wall, and thickened conduction tissue were the meristematic cell disorders triggered by etoxazole. Molecular docking studies showed that etoxazole can interact directly with DNA, tubulins, and the enzymes mentioned above. A. millefolium extract was found to contain a substantial quantity of phenolic compounds. A. millefolium extract, when co-administered with etoxazole, attenuated all toxic effects of etoxazole dose-dependently. In conclusion, A. millefolium may potentially serve as a reliable pharmacological shield against the toxicity of pesticides in non-target organisms.

Abstract
Silver nanoparticles (AgNPs) have unique properties such as chemical stability, malleability, flexibility, high electrical and thermal conductivity, and catalytic activity, making them suitable for various applications. However, they also pose potential toxicity and environmental contamination risks. Natural zeolites (NZs) are considered excellent inorganic support for reducing the toxicity of AgNPs. The scope of this study was to carry out a comparative assessment of the cytotoxic and genotoxic effects of NZ, NZ functionalized with silver nanoparticles (NZ-AgNPs), and commercial AgNPs on fish Astyanax lacustris. Micronucleus (MN) test, cellular morphological change (CMC) test, and the comet assay were used to assess the effects of the nanoparticles. A. lacustris specimens were exposed to a concentrations of 0.1 mg l-1 in the NZs, NZ-AgNPs, and commercial AgNPs for 96 h during the experiment. The results showed no significant difference between the negative control and NZ. Moreover, NZ-AgNPs exhibited reduced toxicities compared to commercial AgNPs, which caused higher levels of alterations and cellular damage. The study concluded that NZs effectively reduced cytotoxicity/genotoxicity in A. lacustris specimens when used to support AgNPs.

Abstract
Intending to compare in vitro cell growth in different conditions, we established cell cultures using fin biopsies of two freshwater fishes, Astyanax bimaculatus and Geophagus proximus. Three different culture media (Leibovitz-L-15, Dulbecco's Modified Eagle Medium [DMEM], and 199) were employed, with or without the addition of AmnioMax, maintaining a standard temperature of 29°C. Based on the results obtained, we standardized a cell growth protocol in which medium 199 was less efficient for both species. Notably, G. proximus cells exhibited superior proliferation in DMEM and L-15 media, whereas A. bimaculatus cells demonstrated better parameters exclusively in the DMEM medium. Successful subculturing of cells with good proliferation index was observed, accompanied by preserved morphological characteristics. Therefore, the methodology outlined in this study represents an advancement in establishing fish cell cultures.

Abstract
The herbicide glyphosate (N-(phosphonomethyl)glycine) efficiently eliminates weeds, is frequently present in surface waters, and may damage the health of various non-target organisms. The main objective of this study was to investigate cytotoxic and genotoxic effects in erythrocytes, DNA, and chromosomes of native South American fish Astyanax lacustris exposed to a glyphosate-based commercial herbicide Templo®. The presenty study evaluated the presence of micronuclei (MN), chromosomal aberrations (CA), DNA damage revealed by comet assay, and cellular morphological changes (CMC) as biomarkers. The A. lacustris specimens were exposed to Templo® for 96 h at concentrations below the permitted Brazilian legislation for freshwater environments. The glyphosate-based herbicide caused MN formation, an increased incidence of CA, DNA damage, and several types of CMC in all tested concentrations on A. lacustris. Notably, analyses were significant (p<0.05) for all concentrations, except in the frequency mean of MN at 3.7 µg/L. Thus, considering the intensive use of commercial glyphosate formulations in crops, the herbicide Templo® represents a potential risk of genotoxicity and cytotoxicity for aquatic organisms. Therefore, environmental protection agencies must review regulations for glyphosate-based herbicides in freshwater environments.

Abstract
Glufosinate-ammonium (GLA), an organophosphate herbicide, is released at high concentrations in the environment, leading to concerns over its potential genotoxic effects. However, few articles are available in the literature reporting the possible cellular and nuclear effects of this compound. We assessed, by in vitro and in vivo micronucleus assays, the genotoxicity of GLA on cultured human lymphocytes and Lymnaea stagnalis hemocytes at six concentrations: 0.010 (the established acceptable daily intake value), 0.020, 0.050, 0.100, 0.200, and 0.500 µg/mL. In human lymphocytes, our results reveal a significant and concentration-dependent increase in micronuclei frequency at concentrations from 0.100 to 0.500 μg/mL, while in L. stagnalis hemocytes, significant differences were found at 0.200 and 0.500 μg/mL. A significant reduction in the proliferation index was observed at all tested concentrations, with the only exception of 0.010 μg/mL, indicating that the exposure to GLA could lead to increased cytotoxic effects. In L. stagnalis, a significant reduction in laid eggs and body growth was also observed at all concentrations. In conclusion, we provided evidence of the genomic and cellular damage induced by GLA on both cultured human lymphocytes and a model organism's hemocytes; in addition, we also demonstrated its effects on cell proliferation and reproductive health in L. stagnalis.

Abstract
Once released into the environment, herbicides can move through soil or surface water to streams and groundwater. Filters containing adsorbent media placed in fields may be an effective solution to herbicide loss in the environment. However, to date, no study has investigated the use of adsorbent materials in intervention systems at field-scale, nor has any study investigated their optimal configuration. Therefore, the aim of this paper was to examine the efficacy of low-cost, coconut-based activated carbon (CAC) intervention systems, placed in streams and tributaries, for herbicide removal. Two configurations of interventions were investigated in two agricultural catchments and one urban area in Ireland: (1) filter bags and (2) filter bags fitted into polyethylene pipes. Herbicide sampling was conducted using Chemcatcher® passive sampling devices in order to identify trends in herbicide exceedances at the sites, and to quantifiably assess, compare, and contrast the efficiency of the two intervention configurations. While the Chemcatcher® passive sampling devices are capable of analysing eighteen different acid herbicides, only six different acid herbicides (2,4-D, clopyralid, fluroxypyr, MCPA, mecoprop and triclopyr) were ever detected within the three catchment areas, which were also the only acid herbicides used therein. The CAC was capable of complete herbicide removal, when the water flow was slow (0.5-1 m3 s-1), and the interventions spanned the width and depth of the waterway. Overall, the reduction in herbicide concentrations was better for the filter pipes than for the filter bags, with a 48% reduction in detections and a 37% reduction in exceedances across all the sampling sites for the filter pipe interventions compared to a 13% reduction in the number of detections and a 24% reduction in exceedances across all sampling sites for the filter bag interventions (p < 0.05). This study demonstrates, for the first time, that CAC may be an effective in situ remediation strategy to manage herbicide exceedances close to the source, thereby reducing the impact on environmental and public health.

Abstract
Textile effluents may be highly toxic and mutagenic. Monitoring studies are important for sustaining the aquatic ecosystems contaminated by these materials, which can cause damage to organisms and loss of biodiversity. We have evaluated the cyto- and genotoxicity of textile effluents on erythrocytes of Astyanax lacustris, before and after bioremediation by Bacillus subitilis treatment. We tested 60 fish (five treatment conditions, four fish per condition, in triplicate). Fish were exposed to contaminants for 7 days. The assays used were biomarker analysis, the micronucleus (MN) test, analysis of cellular morphological changes (CMC), and the comet assay. All concentrations of effluent tested, and the bioremediated effluent, showed damage significantly different from the controls. We conclude that water pollution assessment can be accomplished with these biomarkers. Biodegradation of the textile effluent was only partial, indicating the need for more thorough bioremediation to effect complete neutralization of toxicity.
