Abstract
Exposure to pesticides induces oxidative stress and deleterious effects on various tissues in non-target organisms. Numerous models investigating pesticide exposure have demonstrated metabolic disturbances such as imbalances in amino acid levels within the organism. One potentially effective strategy to mitigate pesticide toxicity involves dietary intervention by supplementing exogenous amino acids and their derivates to augment the body's antioxidant capacity and mitigate pesticide-induced oxidative harm, whose mechanism including bolstering glutathione synthesis, regulating arginine-NO metabolism, mitochondria-related oxidative stress, and the open of ion channels, as well as enhancing intestinal microecology. Enhancing glutathione synthesis through supplementation of substrates N-acetylcysteine and glycine is regarded as a potent mechanism to achieve this. Selection of appropriate amino acids or their derivates for supplementation, and determining an appropriate dosage, are of the utmost importance for effective mitigation of pesticide-induced oxidative harm. More experimentation is required that involves large population samples to validate the efficacy of dietary intervention strategies, as well as to determine the effects of amino acids and their derivates on long-term and low-dose pesticide exposure. This review provides insights to guide future research aimed at preventing and alleviating pesticide toxicity through dietary intervention of amino acids and their derivates.

[PMID: 34782225 DOI: 10.1016/j.jvoice.2021.09.028] [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: 06/14/2021] [Revised: 09/09/2021] [Accepted: 09/23/2021] [Indexed: 10/19/2022]
Abstract
The literature has been shown that exposition by inhalation to chemical compounds can cause vocal disorders and dysphagia in humans, in addition to other symptoms that are manifested according to the type, concentration and duration of exposure to the substance. Cypermethrin and dichlorvos are pesticides widely used in agriculture, public health, veterinary, and home environments. Despite the scientific evidence that cypermethrin and dichlorvos can cause neurodegenerative damage and motor alterations, there are no studies evaluating the toxic effects of these pesticides on the morphology of structures responsible for vocal mobility, especially to the Recurrent Laryngeal Nerve (RLN). Considering the association between vocal disorders in humans and variations in RLN and morphometry, the aim of this study was to evaluate the possible alterations in the microstructure of RLN secondary to subchronic exposure to cypermethrin (pyrethroid) and dichlorvos (organophosphate) in Wistar rats. The experimental protocol (approved by CEUA-UFCSPA: 321/15 and 323/15) consisted of 15 male Wistar rats, allocated in 3 groups: Control (n = 5, exposed to water), Cypermethrin (n = 5, exposed to cypermethrin - 1/10 of the inhalation median lethal concentration [LC50] - 0.25 mg/L) and dichlorvos (n = 5, exposed to dichlorvos - 1/10 of the LC50 - 1.5 mg/L). Inhalation exposure was performed for 4 hours, 5 times per week, for 6 weeks. The nerves were collected, histologically processed and analyzed using morphometric parameters measured using ZEN 2.6 (Zeiss - Germany). The cypermethrin and dichlorvos groups showed significant changes (P < 0.001, ANOVA) in the g-ratio and in the thickness of the myelin sheath of the RLN when compared to the control animals, however, none of the other parameters evaluated showed statistically significant differences. These findings indicate that repeated inhalation exposure to commercial products of cypermethrin and dichlorvos is able to modify the structure of the RLN and possibly generating vocal changes and / or dysphagia.

Abstract
This study delves into the intricate exploration of potential toxic effects resulting from subchronic exposure to fenpropathrin (FNP) on the reproductive system of male SD rats. Adding to the novelty, our study undertakes a pioneering comparison of the effects of curcumin (CUR) and curcumin-encapsulated chitosan nanoparticles (CS.CUR.NPs) on these toxic effects. The study involved a cohort of sixty male SD rats (six groups): vehicle control, CUR, Cs.CUR.NPs, FNP, and two combination groups (FNP with CUR or Cs.CUR.NPs). The synthesized Cs.CUR.NPs nanoparticles underwent meticulous characterization using Fourier Infrared spectroscopy (FT-IR) and transmission electron microscopy (TEM). The findings revealed that FNP caused oxidative stress, sperm abnormalities, reduced motility and sperm count FNP decreased serum LH, FSH, 17-β estradiol, and testosterone levels. FNP downregulated the mRNA expression of the spermatogenesis and steroidogenesis-related genes, While, downregulated hypothalamic KISS-1 and KISS-1r expression. Histopathological alterations were assessed and scored. Surprisingly, the treatment with CUR and Cs.CUR.NPs exhibited remarkable restorative effects on semen quality, sex hormone levels, antioxidant capacity, and mRNA expression of the targeted genes. Notably, Cs.CUR.NPs displayed superior properties when compared to CUR. Nevertheless, further research is imperative to evaluate their efficacy across various bodily tissues.

Abstract
BACKGROUND Brown planthopper (BPH; Nilaparvata lugens) is one of the most serious pests of rice in the world. Insect-resistant genetic engineering is a very effective technology to control BPH. The promoters and cis-regulatory elements inducible by plant-feeding insects are critical for genetic engineering of insect-resistant crops. RESULTS In this study, we cloned a promoter Ptps31 and a 7 bp cis-regulatory sequence that up-regulated downstream genes induced by BPH feeding. The promoter of OsTPS31 (Ptps31) unresponsive to physical damage but responsive to BPH feeding was cloned and functionally verified. The results showed that expression of the OsBPH14 gene driven by the promoter region from -510 to -246 bp in rice could significantly improve the resistance to BPH. The promoter region from -376 to -370 bp (TAGTGTC) was identified as a cis-regulatory sequence related to BPH feeding induction of downstream gene expression. CONCLUSION The findings provide a new promoter and a new cis-regulatory sequence tool for the research on and application of rice BPH resistance genes, as well as a new perspective for functional analysis of the OsTPS31 gene. © 2023 Society of Chemical Industry.

Abstract
Exposure to the herbicide atrazine (ATZ) has deleterious effects on male fertility. This fact underscores the need for measures to protect against the detrimental impact of atrazine exposure on male fertility. The study assessed the protective effects of plantain-based diet (PBD) on rat testes exposed to ATZ by exploring oxid-inflammatory homeostasis. The study evaluated the preventive and therapeutic effects of PBD in a two-phased experiment. Male rats were randomized into seven groups for therapeutic model (Control, ATZ only, ATZ recovery, ATZ + 50% PBD, ATZ + 25% PBD, ATZ + 12.5% PBD and ATZ + quercetin-QUE) while the preventive model had ten groups (Control, ATZ, 50% PBD + ATZ, 25% PBD + ATZ, 12.5% PBD + ATZ and QUE + ATZ). The oxidative stress parameters (DNA fragmentation and MDA level), purinergic activity (ATPase), acetylcholine esterase, and inflammatory markers (NO level, MPO activity, and TNF-α) were increased while the Nrf2 levels were decreased by the ATZ treatment. However, the PBD was able to restore the oxido-inflammatory parameters in the rat testes. The chemical fingerprint of the diet revealed that the diets contained 16 bioactive compounds with quercetin being the most prominent compound. Overall, treatment with PBD was able to protect and prevent the toxicity caused by ATZ by modulating the redox and inflammatory status as well as purinergic activity in the rat testes.

Abstract
Pyrethroid insecticides are a group of widely used bio-mimetic synthetic pesticides. However, recent studies reported that they could have an accumulation effect in human which may cause series of health problems. Estrogen receptors (ER) are a class of nuclear receptors that are vital in proper physiological behavior of estrogens. To investigate the reproductive toxicity of pyrethroids, homology modeling, molecular docking, molecular dynamic simulations (MDs) were conducted to explore the interaction between pyrethroids and ERα from atomic scale. The human ERα (2YJA) was selected as a template protein for homology modeling. Then eight typical pyrethroids and positive control estradiol were docked to the modeled protein. The highest scoring bifenthrin and the lowest scoring permethrin were chosen for in-depth analysis. MDs showed that the complex formed by permethrin with ERα had a lower RMSD value and binding free energies compared to bifenthrin. Based on these results from microscopic dimension, exposure experiments were implemented to validate the primary conclusions. VTG concentrations in male zebrafish's blood were significantly higher under permethrin exposure than bifenthrin, suggesting a stronger estrogenic activity and binding propensity. In this regard, the structural characteristics of molecules were analyzed, expecting to provide theoretical references for subsequent drug design and rational drug application.

Abstract
A growing body of evidence has demonstrated the significance of the gut microbiota in host health, while the association between gut microbiota dysbiosis and multiple diseases is yet elusive in the scenario of exposure to widely used pesticides. Here, we show that gut microbiota dysbiosis involves in host's abnormal lipid metabolism and consequently the non-alcoholic fatty liver disease in Xenopus laevis upon exposure to cis-bifenthrin, one of the most prevalent pyrethroid insecticides in the world. With the guidance of gut microbiota analysis, we found that cis-bifenthrin exposure significantly perturbed the gut microbial community, and the specific taxa that served as biomarkers were identified. Metabolomics profiling and association analysis further showed that a significant change of intestinal metabolites involved in lipid metabolic pathways were induced along with the microbiota dysbiosis upon exposure to cis-bifenthrin. Detailed investigation showed an altered functional regulation of lipids in the liver after cis-bifenthrin exposure and the accumulation of lipid droplets in hepatocytes. Specifically, a change in deoxycholic acid alters bile acid hepatoenteral circulation, which affects lipid metabolism in the liver and ultimately causes the development of fatty liver disease. Collectively, these findings provide novel insight into the gut microbiota dysbiosis upon pesticide exposure and their potential implication in the development of chronic host diseases related to liver metabolic syndrome.

Abstract
Pyrethroids, an effective and widely used class of pesticides, have attracted considerable concerns considering their frequent detection in environmental matrices. However, their potential health risks to amphibians remain unclear. In our study, female Xenopus laevis were exposed to 0, 0.06, and 0.3 μg/L typical pyrethroid, cis-bifenthrin (cis-BF), for 3 months. Elevated activities of both aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were observed, indicating an ongoing liver injury. Furthermore, exposure to cis-BF led to hyperlipidemia and lipid accumulation in the liver of Xenopus. The targeted lipidomic analysis further revealed that treatment with cis-BF perturbed liver steroid homeostasis, as evidenced by the enriched lipids in the steroid biosynthesis pathway. Consistent with the targeted lipidomic result, treatment with cis-BF changed the liver transcriptome profile with induction of 808 and 1230 differentially expressed genes. Kyoto Encyclopedia of Genes and Genomes analysis underlined the adverse effects of cis-BF exposure on steroid biosynthesis, primary bile acid biosynthesis, and the PPAR signaling pathway in the Xenopus liver. Taken together, our study revealed that exposure to cis-BF at environmentally relevant concentrations resulted in lipid metabolic disorder associated with nonalcoholic fatty liver disease of X. laevis, and our results provided new insight into the potential long-term hazards of pyrethroids.

[PMID: 35678313 DOI: 10.1002/jbt.23132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2021] [Revised: 03/10/2022] [Accepted: 05/30/2022] [Indexed: 11/11/2022]
Abstract
Residual amounts of pyrethroids were detected in rice and vegetables of the Indian market. Thus, consumers are exposed to a mixture of pyrethroids on a daily basis through food. Though a large number of studies reported the toxic effects of pyrethroids, there are no reports that used doses equivalent to human consumption. In this study, male Wistar rats were exposed daily to a mixture of pyrethroids for 1-15 months which is equivalent to the amount present in rice and vegetables consumed by an average Indian each day. The oxidant-antioxidant status (lipid peroxidation, nitric oxide; activities of catalase, glutathione peroxidase, glutathione S transferase, and superoxide dismutase) and anatomical changes in the general organs (liver, lung, and kidney) and male reproductive tract tissues (caput, cauda, testis, and prostate) were evaluated. Further, liver and kidney function tests, lipid profile, and complete blood picture were analyzed. Increased oxidative stress, perturbations in the antioxidant enzyme activities, and damage to the anatomical architecture were observed. Disturbances in the liver function and lipid profile were significant. Results of our study demonstrate that exposure to a mixture of pyrethroids at a dose that is equivalent to human consumption can cause systemic and reproductive toxicity, which may ultimately result in the development of lifestyle diseases. This first line of evidence will fuel further studies to determine the impact of food-based pyrethroid exposure on the long-term health of humans and to envisage policies to reduce pesticide content in food products.

Allethrin Promotes Apoptosis and Autophagy Associated with the Oxidative Stress-Related PI3K/AKT/mTOR Signaling Pathway in Developing Rat Ovaries. Int J Mol Sci 2022; 23:ijms23126397. [PMID: 35742842 PMCID: PMC9224321 DOI: 10.3390/ijms23126397] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 06/06/2022] [Accepted: 06/07/2022] [Indexed: 02/04/2023] Open
Abstract
The increased concern regarding the reduction in female fertility and the impressive numbers of women undergoing fertility treatment support the existence of environmental factors beyond inappropriate programming of developing ovaries. Among these factors are pyrethroids, which are currently some of the most commonly used pesticides worldwide. The present study was performed to investigate the developmental effects of the pyrethroid-based insecticide allethrin on ovarian function in rat offspring in adulthood. We mainly focused on the roles of oxidative stress, apoptosis, autophagy and the related pathways in ovarian injury. Thirty-day-old Wistar albino female rats were intragastrically administered 0 (control), 34.2 or 68.5 mg/kg body weight allethrin after breeding from Day 6 of pregnancy until delivery. We found that allethrin-induced ovarian histopathological damage was accompanied by elevations in oxidative stress and apoptosis. Interestingly, the number of autophagosomes in allethrin-treated ovaries was higher, and this increase was correlated with the upregulated expression of genes and proteins related to the autophagic marker LC-3. Furthermore, allethrin downregulated the expression of PI3K, AKT and mTOR in allethrin-treated ovaries compared with control ovaries. Taken together, the findings of this study suggest that exposure to the pyrethroid-based insecticide allethrin adversely affects both the follicle structure and function in rat offspring during adulthood. Specifically, allethrin can induce excessive oxidative stress and defective autophagy-related apoptosis, probably through inactivation of the PI3K/AKT/mTOR signaling pathway, and these effects may contribute to ovarian dysfunction and impaired fertility in female offspring.

Ravula AR, Yenugu S. Transgenerational effects on the fecundity and sperm proteome in rats exposed to a mixture of pyrethroids at doses similar to human consumption. CHEMOSPHERE 2022; 290:133242. [PMID: 34896426 DOI: 10.1016/j.chemosphere.2021.133242] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 12/08/2021] [Accepted: 12/08/2021] [Indexed: 06/14/2023]
Abstract
Pyrethroid based pesticide usage for crop protection resulted in percolation of these compounds into the food chain. Toxicological studies that reflect exposure to pyrethroids through food in the human settings are rare. We conducted animal experimentations using a mixture of pyrethroids that is equivalent to the amount consumed by average individual through rice and vegetables in the Indian context. Male rats treated with a mixture of pyrethroids for 1-12 months displayed decreased transgenerational fecundity, sperm count, activities of 3β- and 17β-HSD and perturbed hormonal profile. At the transcriptome level, the expression of genes involved in spermatogenesis, steroidogenesis, germ cell epigenetic modulators and germ cell apoptosis were altered in the testis. In the sperm lysates of control rats, 506 proteins identified by mass spectrometry. The differential expression of these proteins (treated/control ratio) in the pyrethroid exposed rats was analyzed. Among the 506 proteins, 153 had a ratio of 0; 41 had a ratio ranging from >0 to <0.5; and 10 had a ratio >2.0. Interestingly, the differential expression was transgenerational. 26 proteins that were differentially expressed in the sperm of F0 treated rats continued to remain the same in the F1, F2 and F3 generations, while the differential expression was maintained up to F2 and F1 generations for 46 and 2 proteins respectively. Some of the proteins that continued to be differentially expressed in the later generations are reported to have critical roles in male reproduction. These results indicate that the reduced fecundity observed in the later generations could be due to the continued differential expression that was initiated by pyrethroid treatment in the F0 rats. Results of our study, for the first time, provide evidence that long-term exposure to pyrethroids affects transgenerational fecundity manifested by changes in sperm proteome.

Qu J, Han Y, Zhao Z, Wu Y, Lu Y, Chen G, Jiang J, Qiu L, Gu A, Wang X. Perfluorooctane sulfonate interferes with non-genomic estrogen receptor signaling pathway, inhibits ERK1/2 activation and induces apoptosis in mouse spermatocyte-derived cells. Toxicology 2021; 460:152871. [PMID: 34303733 DOI: 10.1016/j.tox.2021.152871] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 07/17/2021] [Accepted: 07/20/2021] [Indexed: 12/29/2022]
Abstract
Perfluorooctane sulfonate (PFOS) is a widespread persistent organic pollutant. Both epidemiological survey and our previous in vivo study have revealed the associations between PFOS exposure and spermatogenesis disorder, while the underlying mechanisms are far from clear. In the present study, GC-2 cells, a mouse spermatocyte-derived cell line, was used to investigate the toxic effects of PFOS and its hypothetical mechanism of action. GC-2 cells were treated with PFOS (0, 50, 100 and 150 μM) for 24 h or 48 h. Results demonstrated that PFOS dose-dependently inhibited cell viability, induced G0/G1 cell cycle arrest and triggered apoptosis, which might be partly explained by the decrease in cyclin D1, PCNA and Bcl-2 protein expression; increase in Bax protein expression; and activation of caspase-9, -3. In addition, PFOS did not directly transactivate or repress estrogen receptors (ERs) in gene reporter assays, whereas the protein levels of both ERα and ERβ were significantly altered and the downstream ERK1/2 phosphorylation was inhibited by PFOS. Furthermore, pretreatment with specific ERα agonist PPT (1 μM) significantly attenuated the above PFOS-induced effects while specific ERβ agonist DPN (1 μM) accelerated them. These results suggest that PFOS may induce growth inhibition and apoptosis via non-genomic estrogen receptor/ERK1/2 signaling pathway in GC-2 cells, which provides a novel insight regarding the potential role of ERs in mediating PFOS-triggered spermatocyte toxicity.

Abstract
The increase in the size of the global population increases the food and energy demand, making the use of pesticides in agricultural and livestock industries unavoidable. Exposure to pesticides can be toxic to the non-target species, such as humans, wildlife, and livestock, in addition to the target organisms. Various chemicals are used in the livestock industry to control harmful organisms, such as insects, weeds, and parasites. Pigs are one of the most important food sources for humans. In addition, pigs can be used as promising models for assessing the risk of absorption of environmental pollutants through the skin and oral exposure since they are physiologically similar to humans. Exposure to numerous environmental pollutants, such as mycotoxins, persistent organic pollutants, and heavy metals, has been reported to adversely affect growth, fertility, and endocrine homeostasis in pigs. Various pesticides have been observed in porcine tissues, blood, urine, and processed foods; however, there is a lack of comprehensive understanding of their effects on porcine health. This review provides a comprehensive description of the characteristics of pesticides that pigs can be exposed to and how their exposure affects porcine reproductive function, intestinal health, and endocrine homeostasis in vivo and in vitro.

Abstract
Pyrethroids may be related to male reproductive system damage. However, the results of many previous studies are contradictory and uncertain. Therefore, a systematic review and a meta-analysis were performed to assess the relationship between pyrethroid exposure and male reproductive system damage. A total of 72 articles were identified, among which 57 were selected for meta-analysis, and 15 were selected for qualitative analysis. Pyrethroid exposure affected sperm count (SMD= -2.0424; 95% CI, -2.4699 to -1.6149), sperm motility (SMD=-3.606; 95% CI, -4.5172 to -2.6948), sperm morphology (SMD=2.686; 95% CI, 1.9744 to 3.3976), testis weight (SMD=-1.1591; 95% CI, -1.6145 to -0.7038), epididymal weight (SMD=-1.1576; 95% CI, -1.7455 to -0.5697), and serum testosterone level (SMD=-1.9194; 95% CI, -2.4589 to -1.3798) in the studies of rats. We found that gestational and lactational exposure to pyrethroids can reduce sperm count (SMD=1.8469; 95% CI, -2.9010 to -0.7927), sperm motility (SMD=-2.7151; 95% CI, -3.9574 to -1.4728), testis weight (SMD=-1.4361; 95% CI, -1.8873 to -0.9848), and epididymal weight (SMD=-0.6639; 95% CI, -0.9544 to -0.3733) of F1 offspring. Exposure to pyrethroids can increase malondialdehyde (SMD=3.3451; 95% CI 1.9914 to 4.6988) oxide in testes and can reduce the activities of glutathione (SMD=-2.075; 95% CI -3.0651 to -1.0848), superoxide dismutase (SMD=-2.4856; 95% CI -3.9612 to -1.0100), and catalase (SMD=-2.7564; 95% CI -3.9788 to -1.5340). Pyrethroid exposure and oxidative stress could damage male sperm quality. Gestational and lactational pyrethroid exposure affects the reproductive system of F1 offspring.
