Liu H, Wu Y, Wang Z. Long-term exposure to polystyrene nanoparticles at environmentally relevant concentration causes suppression in heme homeostasis signal associated with transgenerational toxicity induction in Caenorhabditis elegans. JOURNAL OF HAZARDOUS MATERIALS 2023; 459:132124. [PMID: 37499489 DOI: 10.1016/j.jhazmat.2023.132124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 07/12/2023] [Accepted: 07/20/2023] [Indexed: 07/29/2023]
Abstract
Heme homeostasis related signaling participates in inducing a protective response when controlling nanopolystyrene toxic effects in parental generation. However, whether the heme homeostasis signal is involved in regulation of transgenerational toxicity of nanopolystyrene toxicity is still unclear. Herein, with the model organism of Caenorhabditis elegans, 0.1-10 μg/L nanopolystyrene particles (PS-NPs) at 20-nm treatment downregulated glb-18, and the decrease was also discovered in the offspring following PS-NPs exposure. Germline glb-18 RNAi induced susceptive property to transgenerational PS-NPs toxicity, suggesting that a decreased GLB-18 level mediated induction of transgenerational toxicity. Importantly, germline GLB-18 transgenerationally activated the function of intestinal HRG-4 in controlling transgenerational PS-NPs toxicity. In transgenerational toxicity control, HRG-1/ATFS-1/HSP-6 was recognized to be the downstream pathway of HRG-4. Briefly, germline GLB-18 in P0 generation can transgenerationally activate the downstream intestinal HRG-4/HRG-1/ATFS-1/HSP-6 pathway among offspring for controlling the transgenerational toxicity of PS-NPs. Findings in the present work strengthens the possible association of heme homeostasis signal changes with transgenerational nanoplastic toxicity within the organisms.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 248:114289.

Abstract
Graphene oxide (GO) exposure may cause damage to C. elegans. However, the role of autophagy and its interactive effect with oxidative response in GO toxicity still remain largely unclear. In the present study, we investigated the protective role of autophagy against GO and its association with oxidative response using C. elegans as an in vivo system. Results indicated that GO exposure induced autophagy in a dose dependent manner in C. elegans. Autophagy inhibitor 3-methyladenine (3-MA) and silencing autophagy genes lgg-1, bec-1 and unc-51 exacerbated the toxicity of GO whereas autophagy activator rapamycin alleviated it. In addition, the antioxidant N-Acetyl-L-cysteine (NAC) effectively suppressed the toxicity of GO with increased resistance to oxidative stress. Worms with RNAi-induced antioxidative genes sod-1, sod-2, sod-3 and sod-4 knockdown were more sensitive to GO. 3-MA increased the expression of superoxide dismutase SOD-3 under GO exposure conditions and exacerbated the toxicity of GO under the anti-oxidation inaction condition by sod-3 RNAi. In contrast, NAC reduced autophagy levels in GO exposed nematodes and increased tolerance to GO in autophagy-defective worms. These results suggested that autophagy and antioxidative response provide complementary protection against GO in C. elegans.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 835:155456.

Abstract
The biological effect of soilborne nanoparticles (NPs) is a manifestation of soil-NMs-bio interactions. Soil factors are known to restructure NPs surfaces and thus influence the nanotoxicity. However, the mechanisms by which environmental factors affecting nano-bio interactions to aggravate or alleviate nanotoxicities are poorly understood. Herein, we compared the toxicity of TiO2 NPs (nTiO2) in five soils using the model nematode (Caenorhabditis elegans), and investigated the variation of nano-bio interactions under different conditions. A correlation analysis showed that pH and dissolved organic matter (DOM) were dominant regulators of nTiO2 toxicity. At the nano-bio interface, low pH (5.0) led to nTiO2 adhesion to micron-sized furrows and aggravated dermal wrinkling, while humid acid (HA) alleviated these impacts. Mechanically, low pH increased nTiO2 adhesion through enhanced electrostatic attraction and subsequent stimulation of mucin and collagen synthesis, resulting in a positive feed cycle of pH-dependent contact nanotoxicity. HA not only prevented nTiO2 adhesion onto the epidermis due to its negative charge, but also relieved the overstimulation of stress response pathways, thereby alleviating nanotoxicity. These findings broaden our knowledge of how NPs induce contact toxicity in soil invertebrates through specific biointerfacial interactions, and highlight the important role of DOM in alleviating the combined hazards of NPs and soil acidification.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 229:113064.

Abstract
Nanomaterials have received increasing attentions owing to their potential hazards to the environment and human health; however, the multi-generational toxicity of graphene oxide under consecutive multi-generational exposure scenario still remains unclear. In the present study, Caenorhabditis elegans as an in vivo model organism was employed to explore the multi-generational toxicity effects of graphene oxide and the underlying mechanisms. Endpoints including development and lifespan, locomotion behaviors, defecation cycle, brood sizes, and oxidative response were evaluated in the parental generation and subsequent five filial generations. After continuous exposure for several generations, worms grew smaller and lived shorter. The locomotion behaviors were reduced across the filial generations and these reduced trends were following the impairments of locomotion-related neurons. In addition, the extended defecation cycles from the third filial generation were in consistency with the relative size reduction of the defecation related neuron. Simultaneously, the fertility function of the nematode was impaired under consecutive exposure as reduced brood sizes and oocytes numbers, increased apoptosis of germline, and aberrant expression of reproductive related genes ced-3, ced-4, ced-9, egl-1 and ced-13 were detected in exposed worms. Furthermore, the antioxidant enzyme, SOD-3 was significantly increased in the parent and filial generations. Thus, continuous multi-generational exposure to graphene oxide caused damage to the neuron development and the reproductive system in nematodes. These toxic effects could be reflected by indicators such as growth inhibition, shortened lifespan, and locomotion behavior impairment and induced oxidative response.

Abstract
Because of the extensive application of electromagnetic technology, its health impact on humans has attracted widespread attention. Due to the lack of a model organism with a stable response to electromagnetic waves, the research conclusions on the biological effects of electromagnetic waves have been vague. Therefore, the aim of this study was to investigate the effects of irradiation by pulsed 9.4 GHz high-power microwaves with a peak power density of 2126 W/cm2 using Caenorhabditis elegans. The development, movement, egg production, ROS, and lifespan of C. elegans were detected at different times after irradiation with different repetitive frequencies of 10, 20, and 50 Hz for 30 min. The results indicated that no obvious changes in basic life indices were induced compared with the sham radiation group, but the survival rate of positive control was significantly decreased compared with other groups, which is of interest for microwave protection research based on C. elegans and provides data for updating safety standards with respect to pulsed high-peak power microwave. © 2021 Bioelectromagnetics Society.

Abstract
Graphene and its derivatives have emerged as a promising nanomaterial in biomedical applications. However, their impact on biosafety continues to be a concern in the field, particularly, their potential cytotoxicity to our immune system. In this study, we used all-atom molecular dynamics simulations to investigate the potential interference of graphene nanosheets in antigen presentation and recognition in immune response. For the illustrated human immunodeficiency virus (HIV) antigen peptide KK10, human leukocyte antigen (HLA), and T cell receptor (TCR) ternary complex, we found that the graphene nanosheet could disrupt the critical protein-protein interactions between TCR and peptide-HLA and impair the antigen recognition by TCR, leaving the antigen presentation unaffected. Moreover, the hydrophobic interaction and van der Waals potential energy collectively drive the spontaneous separation of TCR from the peptide-HLA complex by graphene nanosheets. Our findings demonstrated theoretically how the graphene nanosheet could interfere with the immune response and provided useful insights for reducing the risk of graphene-based nanomaterials in biomedical applications.

Abstract
Along with the rapid development of nanotechnology, the biosafety assessment of nanotechnology products, including nanomaterials (NMs), has become more and more important. The nematode Caenorhabditis elegans is a valuable model organism that has been widely used in the field of biology because of its excellent advantages, including low cost, small size, short life span, and highly conservative genomes with vertebral animals. In recent years, the number of nanotoxicological researchers using C. elegans has been growing. According to these available studies, the present review classified the adverse effects of NMs in C. elegans into systematic, cellular, and molecular toxicity, and focused on summarizing and analyzing the underlying mechanisms of metal, metal oxide, and nonmetallic NMs causing toxic effects in C. elegans. Our findings provide insights into what further studies are needed to assess the biosafety of NMs in the ecosystem using C. elegans. Environ Toxicol Chem 2021;40:2406-2424. © 2021 SETAC.

Abstract
Microfibers (MFs) have recently become an increasingly prevalent pollutant in ecosystems and pose a direct threat to organisms and an indirect threat via adsorption of other pollutants. Here, we used Caenorhabditis elegans to study multigenerational effects of polyethylene terephthalate (PET) MFs (diameter 17.4 μm) by observing the maternal generation (P0) to the seventh offspring generation (F7) with continuous MF exposure. Exposure to 250-μm PET MFs decreased locomotion behavior and induced intestinal reactive oxygen species (ROS) in the P0 generation compared with other PET MF sizes. Moreover, no notably negative effects on survival were observed in any generation during continuous exposure to 250-μm PET MFs. However, the reproduction rate clearly decreased in the F2 and F3 generations but gradually recovered in the F4-F7 generations. Developmental abnormalities showed a close relationship with body length. Although some recovery was confirmed, there were significant decreases in body length in the F2-F5 generations. Interestingly, growth inhibition was also observed in the F6 generation without MF exposure. ROS production and dermal damage in the P0-F5 generations might have resulted in the toxicological responses. To the best of our knowledge, this is the first study to provide evidence of multigenerational toxicity of MFs in C. elegans.

Abstract
In recent years, research on graphene oxide (GO) has developed rapidly in both academic and industrial applications such as electronic, biosensor, drug delivery, water treatment and so forth. Based on the large amount of applications, it is anticipated that GO will inevitably find its own way to the environment, if used are not restricted to prevent their release. Environmental transformation is an important transformation process in the natural environment. In this review, we will summarize the recent developments on environmental transformation of GO in the aquatic environment. Although papers on environmental transformation of graphene-based nanomaterials can be found, a systematic picture describing photo-transformation of GO (dividing into different irradiation sources), environmental transformation of GO in the dark environmental, the environmental toxicity of GO are still lacking. Thus, it is essential to summarize how different light sources will affect the GO structure and reactive oxygen species generation in the photo-transformation process, how GO will react with various natural constituents in the aquatic environment, whether GO will toxic to different aquatic organisms and what will be the interactions between GO and the intracellular receptors in the intracellular level once GO released into the aquatic environment. This review will arouse the realization of potential risk that GO can bring to the aquatic environment and enlighten us to pay attention to behaviors of other two-dimensional GO-like nanomaterials, which have been intensively applied and studied in recent years.

Abstract
In nematode Caenorhabditis elegans, mir-35, a microRNA molecule, was involved in the control of response to nanopolystyrene. Exposure to nanopolystyrene (100 nm) could significantly increase the mir-35 expression. However, the underlying mechanism for this role of mir-35 remains largely unclear. Based on analysis of expression levels, phenotypes, and genetic interactions, we examined the underlying mechanism of intestinal mir-35 in regulating the response to nanopolystyrene. In nematodes, we here found that mir-35 acted in the intestine to regulate the response to nanopolystyrene. In the intestine, NDK-1, homolog of NM23-H1, was identified as the direct target of mir-35, suggesting that intestinal mir-35 regulated the response to nanopolystyrene by suppressing the NDK-1 function. Moreover, intestinal NDK-1 could regulate the response to nanopolystyrene by suppressing the function of FOXO transcriptional factor DAF-16 in the insulin signaling pathway. In nanopolystyrene exposed nematodes, kinase suppressors of Ras (KSR-1 and KSR-2) were further identified as downstream targets of intestinal NDK-1. Moreover, DAF-16 functioned with KSR-1 or KSR-2 in different pathways to regulate the response to nanopolystyrene. Therefore, we have identified an intestinal signaling cascade of mir-35-NDK-1-DAF-16/KSR-1/2 to be required for the control of response to nanopolystyrene. Our results provided an important molecular basis for intestinal response to nanopolystyrene in nematodes.

Abstract
The responses of different organs are important for organisms against the toxicity of environmental toxicants. So far, the neuronal response to nanoplastic exposure and the underlying mechanisms are still largely unclear. Due to the sensitivity to environmental exposures, we here employed Caenorhabditis elegans as an animal model to examine the role of ERK MAPK signaling pathway in the neurons to regulate the response to nanopolystyrene (100 nm). Nanopolystyrene exposure in the range of μg/L could significantly increase expressions of genes (lin-45, mek-2, and mpk-1) encoding ERK MAPK signaling pathway. Nanopolystyrene at the predicted environmental concentration of 1 μg/L could only significantly increase the mpk-1 expression. Meanwhile, RNAi knockdown of any of these genes caused a susceptibility to nanopolystyrene toxicity. ERK/MPK-1 acted in the neurons to regulate the response to nanopolystyrene. Moreover, three genes (ins-4, ins-39, and daf-28) encoding insulin peptides were identified as the downstream targeted genes of neuronal mpk-1 in regulating the response to nanopolystyrene. In nanopolystyrene exposed nematodes, neuronal RNAi knockdown of ins-4, ins-39, or daf-28 decreased expression of intestinal daf-2 encoding insulin receptor and increased expression of intestinal daf-16 encoding FOXO transcriptional factor. Therefore, the neuronal ERK MAPK signaling responded to nanopolystyrene by modulating the insulin signaling-mediated communication between neurons and intestine in nematodes. Our findings are helpful for understanding the molecular basis of neuronal response to nanopolystyrene in organisms.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 720:137666. [PMID: 32325596 DOI: 10.1016/j.scitotenv.2020.137666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 02/28/2020] [Accepted: 02/29/2020] [Indexed: 06/11/2023]
Abstract
Sodium dimethyldithiocarbamate (SDDC) is a widely used heavy metal chelating agent in harmless treatment of wastewater and hazardous waste, but SDDC and its heavy metal chelates may leak into the environment and bring potential ecological risks. In this study, the model organism Caenorhabditis elegans was used to evaluate the toxic effect of SDDC and its heavy metal Cu, Pb chelates. Multiple endpoints were investigated by subacute exposure to SDDC (0.01-100 mg/L) and micro-sized Cu, Pb chelates of SDDC (1-100 mg/L). Our data indicated that the LC50 value of SDDC was 139.39 mg/L (95% Cl: 111.03, 174.75 mg/L). In addition, SDDC was found that concentration of 1 mg/L is a safe limit value for nematode C. elegans, and concentration above 1 mg/L caused adverse effects on the survival, growth, locomotion behaviors and reactive oxygen species (ROS) production of exposed nematodes. Furthermore, all tested SDDC-Cu and SDDC-Pb chelates had obviously lower toxic effect than untreated Cu, Pb metals. These two chelates also had a lower toxic effect than SDDC agent due to its more stable structure. Moreover, SDDC-Cu had a higher toxic effect than SDDC-Pb at the same concentration. Thus, our results suggest that SDDC as a kind of chelating agent applied in harmless treatment of heavy metals, the safe addition limit should not be exceeded.
