Abstract
Deoxyribonucleic acid (DNA) represents the main reservoir of genetic information in the cells, which is why it is protected in the nucleus. Entry into the nucleus is, in general, difficult, as the nuclear membrane is a selective barrier to molecules longer than 40 kDa. However, in some cases, the size of certain nanoparticles (NPs) allows their internalization into the nucleus, thus causing a direct effect on the DNA structure. NPs can also induce indirect effects on DNA through reactive oxygen species (ROS) generation. In this context, nanomaterials are emerging as a disruptive tool for the development of novel therapies in a broad range of biomedical fields; although their effect on cell viability is commonly studied, further interactions with DNA or indirect alterations triggered by the internalization of these materials are not always clarified, since the small size of these materials makes them perfectly suitable for interaction with subcellular structures, such as the nucleus. In this context, and using as a reference the predicted interactions presented in a computational model, we describe and discuss the observed direct and indirect effects of the implicated nanomaterials on DNA.

[PMID: 37792034 PMCID: PMC10616207 DOI: 10.1007/s00403-023-02725-z] [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: 07/31/2023] [Revised: 07/31/2023] [Accepted: 09/06/2023] [Indexed: 10/05/2023]
Abstract
Microencapsulation has received extensive attention because of its various applications. Since its inception in the 1940s, this technology has been used across several areas, including the chemical, food, and pharmaceutical industries. Over-the-counter skin products often contain ingredients that readily and unevenly degrade upon contact with the skin. Enclosing these substances within a silica shell can enhance their stability and better regulate their delivery onto and into the skin. Silica microencapsulation uses silica as the matrix material into which ingredients can be embedded to form microcapsules. The FDA recognizes amorphous silica as a safe inorganic excipient and recently approved two new topical therapies for the treatment of rosacea and acne. The first approved formulation uses a novel silica-based controlled vehicle delivery technology to improve the stability of two active ingredients that are normally not able to be used in the same formulation due to potential instability and drug degradation. The formulation contains 3.0% benzoyl peroxide (BPO) and 0.1% tretinoin topical cream to treat acne vulgaris in adults and pediatric patients. The second formulation contains silica microencapsulated 5.0% BPO topical cream to treat inflammatory rosacea lesions in adults. Both formulations use the same amorphous silica sol-gel microencapsulation technology to improve formulation stability and skin compatibility parameters.

Abstract
Nano-silicon dioxide (nano-SiO2) has a great deal of application in food packaging, as antibacterial food additives, and in drug delivery systems but this nanoparticle, despite its wide range of utilizations, can generate destructive effects on organs such as the liver, kidney, and lungs. This study is aimed at investigating the toxicological effects of nano-SiO2 through apoptotic factors. For this purpose, 40 female rats in 4 groups (n = 10) received 300, 600, and 900 mg/kg/day of nano-SiO2 at 20-30 nm size orally for 20 days. Relative expression of Caspase3, Bcl-2, and BAX genes in kidney and liver was evaluated in real time-PCR. The results indicated the overexpression of BAX and Caspase3 genes in the liver and kidney in groups receiving 300 and 900 mg/kg/day of nano-SiO2. Bcl-2 gene was up-regulated in the liver and kidney at 600 mg/kg/day compared to the control group. Overexpression of the Bcl-2 gene in the kidney in 300 and 900 mg/kg/day recipient groups was observed (P ≤ 0.05). Histopathological examination demonstrated 600 mg/kg/day hyperemia in the kidney and lungs. In addition, at 900 mg/kg/day were distinguished scattered necrosis and hyperemia in the liver. The rate of epithelialization in the lungs increased. The nano-SiO2 at 300 and 900 mg/kg/day can induce more cytotoxicity in the liver and lung after oral exposure. However, cytotoxicity of nano-SiO2 at 600 mg/kg/day in the kidney and lung was noticed. Hence, the using of nano-SiO2 as an additive and food packaging should be more considered due to their deleterious effects.

Amorphous silica nanoparticles cause abnormal cytokinesis and multinucleation through dysfunction of the centralspindlin complex and microfilaments. Part Fibre Toxicol 2023; 20:34. [PMID: 37608338 PMCID: PMC10464468 DOI: 10.1186/s12989-023-00544-8] [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: 04/10/2023] [Accepted: 07/18/2023] [Indexed: 08/24/2023] Open
Abstract
BACKGROUND With the large-scale production and application of amorphous silica nanoparticles (aSiNPs), its adverse health effects are more worthy of our attention. Our previous research has demonstrated for the first time that aSiNPs induced cytokinesis failure, which resulted in abnormally high incidences of multinucleation in vitro, but the underlying mechanisms remain unclear. Therefore, the purpose of this study was firstly to explore whether aSiNPs induced multinucleation in vivo, and secondly to investigate the underlying mechanism of how aSiNPs caused abnormal cytokinesis and multinucleation. METHODS Male ICR mice with intratracheal instillation of aSiNPs were used as an experimental model in vivo. Human hepatic cell line (L-02) was introduced for further mechanism study in vitro. RESULTS In vivo, histopathological results showed that the rate of multinucleation was significantly increased in the liver and lung tissue after aSiNPs treatment. In vitro, immunofluorescence results manifested that aSiNPs directly caused microfilaments aggregation. Following mechanism studies indicated that aSiNPs increased ROS levels. The accumulation of ROS further inhibited the PI3k 110β/Aurora B pathway, leading to a decrease in the expression of centralspindlin subunits MKLP1 and CYK4 as well as downstream cytokines regulation related proteins Ect2, Cep55, CHMP2A and RhoA. Meanwhile, the particles caused abnormal co-localization of the key mitotic regulatory kinase Aurora B and the centralspindlin complex by inhibiting the PI3k 110β/Aurora B pathway. PI3K activator IGF increased the phosphorylation level of Aurora B and improved the relative ratio of the centralspindlin cluster. And ROS inhibitors NAC reduced the ratio of multinucleation, alleviated the PI3k 110β/Aurora B pathway inhibition, and then increased the expression of MKLP1, CYK4 and cytokinesis-related proteins, whilst NAC restored the clustering of the centralspindlin. CONCLUSION This study demonstrated that aSiNPs led to multinucleation formation both in vivo and in vitro. ASiNPs exposure caused microfilaments aggregation and inhibited the PI3k 110β/Aurora B pathway through excessive ROS, which then hindered the centralspindlin cluster as well as restrained the expression of centralspindlin subunits and cytokinesis-related proteins, which ultimately resulted in cytokinesis failure and the formation of multinucleation.

Abstract
The demand for sustainable products is increasing worldwide and cosmetic industry is not an exception. Besides exploring nature as source of new ingredients, their production must be sustainable and should use environmentally friendly processes. In this work, biogenic silica microparticles were synthesized from sugarcane ash, and their potential application as cosmetic and skincare ingredient was evaluated. For such application, several properties were validated, including cytotoxicity in skin keratinocytes, potential sensitization effect on skin peptides, stimulation of pro-collagen I alpha 1, wound healing capacity, as well as the ingredient stability along a storage period. Biogenic silica showed to be non-cytotoxic on skin keratinocytes, at concentrations up to 5 wt%, and non-skin sensitizer. A positive effect on the stimulation of pro-collagen I alpha 1 suggests a potential anti-ageing activity, while the migration of fibroblasts to a wounded area suggests a regenerative capacity. Under an accelerated stability study, biogenic silica showed an increase on the loss on drying, but no changes were observed on its functional properties, mainly oil absorption capacity, as well the microbiological quality, which was maintained. Overall, novel biogenic silica microparticles produced from a sustainable source are safe, stable over time and have potential to be used as a cosmetic and skincare ingredient.

Abstract
Numerous studies have shown that exposure to micro- or nano-plastics led to the cell viability and function of macrophages in the intestine tissue might be one possible mechanism. This study investigated the cytotoxicity and pro-inflammatory effect of 80 nm polystyrene-nano-plastic (PS-NP) and 3 µm PS-micro-plastic (PS-MP) on mouse macrophages RAW264.7 cells. Our results showed that exposure to PS-NP or PS-MP induced apoptosis of cells at 5 or 10 μg/mL, respectively. Besides, PS-NP enhanced the secretion of inflammatory cytokines (Tumor necrosis factor-α, Interleukin-6 and Interleukin-10) with the lowest effective concentration (LOEC) of 1, 0.01, and 0.01 μg/mL, respectively. PS-MP enhanced secretion of TNF-α and IL-10 with the LOEC of 1 and 0.01 μg/mL, respectively. We further studied the possible mechanisms of the effects of PS-NP or PS-MP on RAW264.7 cells. We found they might cause cytotoxicity and inflammatory effects by producing reactive oxygen species and nitric oxide in the cells. Accordingly, our results demonstrated that PS-NP and PS-MP had cytotoxicity and pro-inflammatory effect on macrophages, which might further lead to intestinal inflammation. Moreover, we revealed that the PS-NP had more potent adverse impacts on macrophages than PS-MP.

Silica nanoparticles perturbed mitochondrial dynamics and induced myocardial apoptosis via PKA-DRP1-mitochondrial fission signaling. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 842:156854. [PMID: 35750168 DOI: 10.1016/j.scitotenv.2022.156854] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 06/15/2022] [Accepted: 06/17/2022] [Indexed: 05/20/2023]
Abstract
Silica nanoparticles (SiNPs) are among the most abundantly produced nanosized particles in the global market, and their potential toxicity has aroused a great concern. Increasing epidemiological investigations and experimental evidence revealed the threaten of SiNPs exposure to cardiovascular system. The myocardial toxicity caused by SiNPs was gradually demonstrated, nevertheless, the underlying mechanisms remain unclear. In view of mitochondria serving as the centrality in the prominent of cardiovascular disease, we investigated the role of mitochondria and related mechanisms in SiNPs-induced adverse effects on cardiomyocytes. As a result, SiNPs were found in cytoplasm, accompanied with morphological alterations in mitochondria, such as cristae fracture or disappearance, vacuolation. The induction of mitochondrial dysfunction by SiNPs was confirmed, as indicated by the excessive reactive oxygen species (ROS) formation, and blockage of cellular respiratory and ATP production. Concomitantly, SiNPs activated mitochondria-mediated apoptotic signaling in view of the up-regulated BAX, increased Caspase-9 cleavage and declined Bcl-2, ultimately resulting in myocardial apoptosis. It was noteworthy that SiNPs disturbed mitochondrial dynamics toward fission phenotype, which was supported by the dysregulated fission/fusion regulators. Especially, DRP1 and its phosphorylated level at s616 (p-DRP1s616) were up-regulated, whilst its phosphorylated level at s637 (p-DRP1s637) and PKA phosphorylation were down-regulated in SiNPs-treated cardiomyocytes in a dose-dependent manner. More importantly, the mechanistic investigations revealed PKA-DRP1-mediated mitochondrial fission was responsible for SiNPs-induced cardiomyocyte apoptosis through the mitochondria-mediated apoptotic way. This study firstly demonstrated the disturbance of mitochondrial dynamics played a crucial role in cardiomyocyte apoptosis caused by SiNPs, attributing to PKA-DRP1-mitochondrial fission signaling.

Abstract
Purpose The protein corona surrounding nanoparticles has attracted considerable attention as it induces subsequent inflammatory responses. Although mesoporous silica nanoparticles (MSN) are commonly used in medicines, cosmetics, and packaging, the inflammatory effects of the MSN protein corona on the cutaneous system have not been investigated till date. Methods We examined the greater plasma protein adsorption on MSN leads to serious inflammatory reactions in Dermatophagoides farinae extract (DFE)-induced mouse atopic dermatitis (AD)-like skin inflammation because of increased uptake by keratinocytes. Results We compare the AD lesions induced by MSN and colloidal (non-porous) silica nanoparticles (CSN), which exhibit different pore architectures but similar dimensions and surface chemistry. MSN-corona treatment of severe skin inflammation in a DFE-induced in vivo AD model greatly increases mouse ear epidermal thickness and infiltration of immune cells compared with the CSN-corona treatment. Moreover, MSN-corona significantly increase AD-specific immunoglobulins, serum histamine, and Th1/Th2/Th17 cytokines in the ear and lymph nodes. MSN-corona induce more severe cutaneous inflammation than CSN by significantly decreasing claudin-1 expression. Conclusion This study demonstrates the novel impact of the MSN protein corona in inducing inflammatory responses through claudin-1 downregulation and suggests useful clinical guidelines for MSN application in cosmetics and drug delivery systems.

[PMID: 35933425 PMCID: PMC9356467 DOI: 10.1186/s12989-022-00495-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Accepted: 07/28/2022] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND Metabolic syndrome (MetS) exacerbates susceptibility to inhalation exposures such as particulate air pollution, however, the mechanisms responsible remain unelucidated. Previously, we determined a MetS mouse model exhibited exacerbated pulmonary inflammation 24 h following AgNP exposure compared to a healthy mouse model. This enhanced response corresponded with reduction of distinct resolution mediators. We hypothesized silver nanoparticle (AgNP) exposure in MetS results in sustained pulmonary inflammation. Further, we hypothesized treatment with resolvin D1 (RvD1) will reduce exacerbations in AgNP-induced inflammation due to MetS. RESULTS To evaluate these hypotheses, healthy and MetS mouse models were exposed to vehicle (control) or AgNPs and a day later, treated with resolvin D1 (RvD1) or vehicle (control) via oropharyngeal aspiration. Pulmonary lung toxicity was evaluated at 3-, 7-, 14-, and 21-days following AgNP exposure. MetS mice exposed to AgNPs and receiving vehicle treatment, demonstrated exacerbated pulmonary inflammatory responses compared to healthy mice. In the AgNP exposed mice receiving RvD1, pulmonary inflammatory response in MetS was reduced to levels comparable to healthy mice exposed to AgNPs. This included decreases in neutrophil influx and inflammatory cytokines, as well as elevated anti-inflammatory cytokines. CONCLUSIONS Inefficient resolution may contribute to enhancements in MetS susceptibility to AgNP exposure causing an increased pulmonary inflammatory response. Treatments utilizing specific resolution mediators may be beneficial to individuals suffering MetS following inhalation exposures.

Abstract
Understanding the underlying interactions of nanoparticles (NPs) with cells is crucial to the nanotoxicological research. Evidences suggested lysosomes as a vital target upon the accumulation of internalized NPs, and lysosomal damage and autophagy dysfunction are emerging molecular mechanisms for NPs-elicited toxicity. Nevertheless, the interaction with lysosomes, ensuing adverse effects and the underlying mechanisms are still largely obscure, especially in NPs-induced vascular toxicity. In this study, silica nanoparticles (SiNPs) were utilized to explore the adverse effects on lysosome in vascular endothelial cells by using in vitro cultured human endothelial cells (HUVECs), and in-depth investigated the mechanisms involved. Consequently, the internalized SiNPs accumulated explicitly in the lysosomes, and caused lysosomal dysfunction, which were prominent on the increased lysosomal membrane permeability, decline in lysosomal quantity, destruction of acidic environment of lysosome, and also disruption of lysosomal enzymes activities, resulting in autophagy flux blockage and autophagy dysfunction. More importantly, mechanistic results revealed the SiNPs-caused lysosomal impairments and resultant autophagy dysfunction could promote oxidative stress, DNA damage and the eventual cell apoptosis activated by ROS/PARP1/AIF signaling pathway. These findings improved the understanding of SiNPs-induced vascular injury, and may provide novel information and warnings for SiNPs applications in the fields of nanomedicine.

Abstract
Silver has been known since ancient times on account of its pronounced antiseptic properties. Currently, its antibacterial, antiviral, and fungicidal properties are highly desired in the food and cosmetic industries, in medicine, and pharmacology. Silver exhibits toxic effects not only on pathogenic organisms but also on healthy cells. Over the past 20 years, nanosilver, a new form of silver, has been introduced in various areas of industry. The transition to the nanoscale form results in the revision of standard approaches to items, including those based on this element, and the emergence of such a novel research area as nanosafety. In this review, we address the history of using different forms of silver, the mechanisms of its interaction with living cells, toxic properties, biokinetic parameters, capability for accumulation in different organs, effects on cognitive functions, and the clinically known argyrosis condition. Relevant publications are critically analyzed and conclusions are drawn. The broader incorporation of such a weakly biophilic element as silver in the biosphere and ecosphere calls for our understanding of biochemical processes underlying the interaction of this element, in its different forms, with living cells and multicellular organisms.

Abstract
Stem cell (SC)-based therapies hold the potential to revolutionize therapeutics by enhancing the body's natural repair processes. Currently, there are only three SC therapies with marketing authorization within the European Union. To optimize outcomes, it is important to understand the biodistribution and behavior of transplanted SCs in vivo. A variety of imaging agents have been developed to trace SCs; however, they mostly lack the ability to simultaneously monitor the SC function and biodistribution at high resolutions. Here, we report the synthesis and application of a nanoparticle (NP) construct consisting of a gold NP core coated with rhodamine B isothiocyanate (RITC)-doped mesoporous silica (AuMS). The MS layer further contained a thiol-modified internal surface and an amine-modified external surface for dye conjugation. Highly fluorescent AuMS of three different sizes were successfully synthesized. The NPs were non-toxic and efficiently taken up by limbal epithelial SCs (LESCs). We further showed that we can functionalize AuMS with a reactive oxygen species (ROS)-sensitive fluorescent dye using two methods, loading the probe into the mesopores, with or without additional capping by a lipid bilayer, and by covalent attachment to surface and/or mesoporous-functionalized thiol groups. All four formulations displayed a ROS concentration-dependent increase in fluorescence. Further, in an ex vivo SC transplantation model, a combination of optical coherence tomography and fluorescence microscopy was used to synergistically identify AuMS-labeled LESC distribution at micrometer resolution. Our AuMS constructs allow for multimodal imaging and simultaneous ROS sensing of SCs and represent a promising tool for in vivo SC tracing.

Abstract
Background Silica nanoparticles (SiO2 NPs) are extensively applied in the biomedical field. The increasing medical application of SiO2 NPs has raised concerns about their safety. However, studies on SiO2 NP-induced retinal toxicity are lacking. Methods We investigated the retinal toxicity of SiO2 NPs with different sizes (15 and 50 nm) in vitro and in vivo along with the underlying mechanisms. The cytotoxicity of SiO2 NPs with different sizes was assessed in R28 human retinal precursor cells by determining the ATP content and LDH release. The cell morphologies and nanoparticle distributions in the cells were analyzed by phase-contrast microscopy and transmission electron microscopy, respectively. The mitochondrial membrane potential was examined by confocal laser scanning microscopy. The retinal toxicity induced by SiO2 NPs in vivo was examined by immunohistochemical analysis. To further investigate the mechanism of retinal toxicity induced by SiO2 NPs, reactive oxygen species (ROS) generation, glial cell activation and inflammation were monitored. Results The 15-nm SiO2 NPs were found to have higher cytotoxicity than the larger NPs. Notably, the 15-nm SiO2 NPs induced retinal toxicity in vivo, as demonstrated by increased cell death in the retina, TUNEL-stained retinal cells, retinal ganglion cell degeneration, glial cell activation, and inflammation. In addition, The SiO2 NPs caused oxidative stress, as demonstrated by the increase in the ROS indicator H2DCF-DA. Furthermore, the pretreatment of R28 cells with N-acetylcysteine, an ROS scavenger, attenuated the ROS production and cytotoxicity induced by SiO2 NPs. Conclusions These results provide evidence that SiO2 NPs induce size-dependent retinal toxicity and suggest that glial cell activation and ROS generation contribute to this toxicity.

Abstract
With wide application of Zinc oxide (ZnO) nanoparticles, their biological toxicity has received more and more attention in recent years. In this research, two ZnO dispersions with different particle sizes, small size Zinc oxide (S-ZnO) and big size Zinc oxide (B-ZnO), were prepared using polycarboxylic acid as dispersant. We found that the S-ZnO nanoparticles showed stronger toxicity on Human Pulmonary Alveolar Epithelial Cells (HPAEpiC) under same concentration. Only 9 ppm S-ZnO could decrease HPAEpiC viability to about 50%, which means that, a small amount of well-dispersed ZnO nanoparticles in industrial production process may cause serious damage to the human body through oral inhalation. Focusing on mechanism for cytotoxicity, ZnO nanoparticles promoted generation and accumulation of Reactive Oxygen Species (ROS) in mitochondria via inhibiting Superoxide Dismutase (SOD) enzyme activity and reducing Glutathione (GSH) content. ROS in turn opened the mitochondrial Ca2+ pathway and lowered the Mitochondrial Membrane Potentials (MMP), leading to cell death. To simulate the lung environment in vitro, mixed dipalmitoyl phosphatidylcholine (DPPC) and ZnO nanoparticles (1:1) were incubated for 72 hours and then cytotoxicity was evaluated on HPAEpiC. Results showed that the cell viability was significantly increased, which proved that the DPPC effectively inhibited the toxicity of ZnO nanoparticles.

Abstract
Silica-based nanoframeworks have been extensively studied for diagnosing and treating hepatocellular carcinoma (HCC). Several reviews have summarized the advantages and disadvantages of these nanoframeworks and their use as drug-delivery carriers. Encouragingly, these nanoframeworks, especially those with metal elements or small molecular drugs doping into the skeleton structure or modifying onto the surface of nanoparticles, could be multifunctional components participating in HCC diagnosis and treatment rather than functioning only as drug-delivery carriers. Therefore, in this work, we described the research progress of silica-based nanoframeworks involved in HCC diagnosis (plasma biomarker detection, magnetic resonance imaging, positron emission tomography, photoacoustic imaging, fluorescent imaging, ultrasonography, etc.) and treatment (chemotherapy, ferroptotic therapy, radiotherapy, phototherapy, sonodynamic therapy, immunotherapy, etc.) to clarify their roles in HCC theranostics. Further, the future expectations and challenges associated with silica-based nanoframeworks were highlighted. We believe that this review will provide a comprehensive understanding for researchers to design novel, functional silica-based nanoframeworks that can effectively overcome HCC.

Abstract
The toxic effects of the amorphous silica nanoparticles have not been thoroughly studied. Moreover, the majority of the in vivo investigations were performed using an inhalation exposure method. The current study aimed to explore the potential toxic effects of silica nanoparticles (SiNPs) after the treatment of adult male rats with two different concentrations (500 and 1000 ppm) via drinking water for 28 days. The genotoxicity, antioxidant status, and liver and kidney functions were assessed. Besides, histopathological and immunohistochemical evaluations were performed. The results showed a significant elevation in the malondialdehyde (MDA) level concurrent with a reduction in total reduced glutathione (GSH) concentration and catalase activity in the 1000-ppm SiNP-exposed rats as well as increase in ALT and AST activity confirmed by various histopathological alterations detected in liver. Also, in the 1000-ppm SiNP-exposed animals, there was an elevation in urea and creatinine levels confirmed by histopathological alterations detected in kidneys. Immunohistochemical findings in both liver and kidneys indicated strong expression of caspase-3 in the 1000-ppm SiNP-treated rats compared with the control and 500-ppm SiNP-treated groups. Such findings indicated that the 1000-ppm SiNPs exerted severe hepato-renal toxic impacts when compared with the control and 500-ppm SiNP-exposed rats.

Abstract
Silicon dioxide nanoparticles (SiO2 NPs) are extensively used in cosmetics, food, and drug delivery. The main mechanism of SiO2 NPs toxicities depends on oxidative stress. Ginseng (Panax ginseng Meyer) is used in various medicinal applications because of its antioxidant efficiency. Therefore, the present study was carried out to investigate the possible combated role of ginseng against SiO2 NPs toxicity in rat liver. Thirty-five male rats (160-180 g) were allocated into five groups of seven rats each, randomly. The first group was used as a control while groups 2, 3, 4, and 5 were treated orally with ginseng (Gin; 75 mg/kg, 1/10 LD50 ), SiO2 NPs, (200 mg/kg, 1/10 LD50 ), Gin + SiO2 NPs (protection group), and SiO2 NPs + Gin (therapeutic group) for 5 weeks, respectively. Treatment with SiO2 NPs increased lipid peroxidation, liver function enzymes, and decreased antioxidant enzymes (SOD, CAT, GPx, GST) activity and non-enzymatic antioxidant (GSH) level. SiO2 NPs administration motivated liver apoptosis as revealed by the upregulation of the apoptotic genes, Bcl2-associated x protein (Bax), and Beclin 1 and downregulation of the anti-apoptotic gene, B-cell lymphoma 2 (Bcl2) as well as increase in DNA damage. Also, SiO2 NPs administration caused inflammation as indicated by upregulation of the inflammation-related genes (interleukin 1 beta [IL1β], tumor necrosis factor-alpha [TNFα], nuclear factor kappa B [NFκB], cyclooxygenase 2 [Cox2], transforming growth factor-beta 1 [TGFβ1]) as well as cell cycle arrest in the G0/G1 phase of liver cells. Moreover, histopathological examination proved the biochemical and molecular perturbations occurred due to SiO2 NPs toxicity. On the other hand, ginseng caused a significant modulation on the deleterious effects induced by SiO2 NPs in rat liver. In conclusion, ginseng has a potent preventive effect than the therapeutic one and might be used in the treatment of SiO2 NPs hepatotoxicity.

Abstract
Air pollution and the application of Silica nanoparticles (SiNPs) have increased the risk of human exposure to SiNPs. SiNPs are known to induce cytotoxicity in spermatocyte cells (GC-2spd cells) of mice and male reproductive system damage. However, the expression profiles of miRNA and mRNA and the molecular mechanism of miRNA-mRNA integration in reproductive toxicity induced by SiNPs in GC-2spd cells are still unclear. Therefore, GC-2spd cells were divided into 0 μg/mL and 5 μg/mL SiNPs groups, and the cells were collected and analyzed after passaging for 30 generations using miRNA microarray and Illumina high-throughput sequencing (Illumina HiSeq) for the integrated analysis of miRNA and mRNA expression. Both miRNA Microarray and Illumina Hiseq identified 15 significant differentially expressed miRNAs and 1648 significant differentially expressed mRNAs. Gene Ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and miRNA-gene-pathway-network analysis revealed 15 significant differentially expressed miRNAs that could regulate the DNA replication and the fatty acid metabolism, respectively. Furthermore, the mRNA-mRNA regulatory network analysis revealed that Pkfl (phosphofructokinase, liver, B-type) and DHCR24 (24-dehydrocholesterol reductase) were highly expressed, but also affected DNA replication and fatty acid metabolism in SiNPs-treated GC-2spd cells. Additionally, miRNA-mRNA integration analysis revealed that miRNA-138-1-3p might have a regulatory relationship with fatty acid metabolism and DNA replication. It is confirmed that SiNPs could decrease the expression of 10 miRNAs and increase the expression of 5 miRNAs. These findings suggest that the cytotoxicity of GC-2spd cells induced by SiNPs depends on the deregulation of multiple miRNAs, which regulate the DNA replication and fatty acid metabolism. Our results are the first to establish an integrated analysis of miRNA-mRNA interactions and mRNA-mRNA and defines multiple pathways involved in SiNPs-treated GC-2spd cells.

Krętowski R, Kusaczuk M, Naumowicz M, Cechowska-Pasko M. The Pro-Apoptotic Effect of Silica Nanoparticles Depends on Their Size and Dose, as Well as the Type of Glioblastoma Cells. Int J Mol Sci 2021; 22:ijms22073564. [PMID: 33808150 PMCID: PMC8037515 DOI: 10.3390/ijms22073564] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 03/23/2021] [Accepted: 03/25/2021] [Indexed: 02/04/2023] Open
Abstract
Despite intensive investigations, nanoparticle-induced cellular damage is an important problem that has not been fully elucidated yet. Here, we report that silica nanoparticles (SiNPs) demonstrated anticancer influence on glioblastoma cells by the induction of apoptosis or necrosis. These effects are highly cell type-specific, as well as dependent on the size and dose of applied nanoparticles. Exposure of LN-18 and LBC3 cells to different sizes of SiNPs-7 nm, 5-15 nm, or 10-20 nm-at dosages, ranging from 12.5 to 1000 µg/mL, for 24 and 48 h reduced the viability of these cells. Treatment of LN-18 and LBC3 cells with 7 nm or 10-20 nm SiNPs at doses ≥50 µg/mL caused a strong induction of apoptosis, which is connected with an increase of intracellular reactive oxygen species (ROS) production. The 5-15 nm SiNPs exhibited distinct behavior comparing to silica nanoparticles of other studied sizes. In contrast to LBC3, in LN-18 cells exposed to 5-15 nm SiNPs we did not observe any effect on apoptosis. These nanoparticles exerted only strong necrosis, which was connected with a reduction in ROS generation. This suggests that SiNPs can trigger different cellular/molecular effects, depending on the exposure conditions, the size and dose of nanoparticles, and cell type of glioblastoma.

Abstract
Silica nanoparticles (SiO2 NPs) are commonly used in medical and pharmaceutical fields. Research into the cytotoxicity and overall proteomic changes occurring during initial exposure to SiO2 NPs is limited. We investigated the mechanism of toxicity in human liver cells according to exposure time [0, 4, 10, and 16 h (h)] to SiO2 NPs through proteomic analysis using mass spectrometry. SiO2 NP-induced cytotoxicity through various pathways in HepG2 cells. Interestingly, when cells were exposed to SiO2 NPs for 4 h, the morphology of the cells remained intact, while the expression of proteins involved in mRNA splicing, cell cycle, and mitochondrial function was significantly downregulated. These results show that the toxicity of the nanoparticles affects protein expression even if there is no change in cell morphology at the beginning of exposure to SiO2 NPs. The levels of reactive oxygen species changed significantly after 10 h of exposure to SiO2 NPs, and the expression of proteins associated with oxidative phosphorylation, as well as the immune system, was upregulated. Eventually, these changes in protein expression induced HepG2 cell death. This study provides insights into cytotoxicity evaluation at early stages of exposure to SiO2 NPs through in vitro experiments.

Disturbance of cellular homeostasis as a molecular risk evaluation of human endothelial cells exposed to nanoparticles. Sci Rep 2021; 11:3849.

Abstract
Even though application of nanoparticles in medicine seems to provide unique solutions for drug delivery and diagnosis diseases, understanding interactions between nanoscale materials and biological systems is imperative. Therefore, this study determined the effect of different types of nanoparticles (NPs) on human endothelial cells and examined the types of toxicity responses they can induce. Four different types of NPs were tested (PLA/MMT/TRASTUZUMAB, PLA/EDTMP, PLGA/MDP, and Pluronic F127 MICELLES), representing three putative areas of application: anticancer therapy, scintigraphy, and cosmetology. The experiments were performed on immortalized human umbilical vein endothelial cells (HUVEC-STs). Light contrast phase microscopy as well as cell viability assays showed that only Pluronic F127 MICELLES decreased the number of HUVEC-STs in contrast to PLA/MMT/TRASTUZUMAB, PLA/EDTMP, and PLGA/MDP NPs, which altered cell morphology, but not their confluency. The tested NPs induced not only DNA strand-breaks and alkali-labile sites, but also internucleosomal DNA fragmentation, visualized as a DNA ladder pattern typical of apoptosis. Moreover, generation of free radicals and subsequent mitochondrial membrane potential collapse showed the significance of free radical production during interactions between NPs and endothelial cells. High concentrations of NPs had different degrees of toxicity in human endothelial cells and affected cell proliferation, redox homeostasis, and triggered mitochondrial dysfunction.

Abstract
With the increasing production and application of engineered amorphous silica nanoparticles (aSiNPs), people have more opportunities to be exposed to aSiNPs. However, the knowledge of its adverse health effects and related mechanisms is still limited, compared with the well-studied crystalline micron-sized silica. Since small differences in the physical–chemical properties of nanoparticles could cause significant differences in the toxic effect, it is important to distinguish how these variations influence the outcoming toxicity. Notably, particle size, as one of the essential characterizations of aSiNPs, is relevant to its biological activities. Thus, the aim of this systematic review was to summarize the relationship between the particle size of aSiNPs and its adverse biological effects. In order to avoid the influence of complicated in vivo experimental conditions on the toxic outcome, only in vitro toxicity studies which reported on the cytotoxic effect of different sizes aSiNPs were included. After the systematic literature retrieval, selection, and quality assessment process, 76 eligible scientific papers were finally included in this review. There were 76% of the studies that concluded a size-dependent cytotoxicity of aSiNPs, in which smaller-sized aSiNPs possessed greater toxicity. However, this trend could be modified by certain influence factors, such as the synthetic method of aSiNPs, particle aggregation state in cell culture medium, toxicity endpoint detection method, and some other experimental conditions. The effects of these influence factors on the size-dependent cytotoxicity of aSiNPs were also discussed in detail in the present review.

Particulate Matter (PM 2.5) from Biomass Combustion Induces an Anti-Oxidative Response and Cancer Drug Resistance in Human Bronchial Epithelial BEAS-2B Cells. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17218193. [PMID: 33171923 PMCID: PMC7664250 DOI: 10.3390/ijerph17218193] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 10/30/2020] [Accepted: 11/03/2020] [Indexed: 02/07/2023]
Abstract
Nearly half of the world’s population relies on combustion of solid biofuels to cover fundamental energy demands. Epidemiologic data demonstrate that particularly long-term emissions adversely affect human health. However, pathological molecular mechanisms are insufficiently characterized. Here we demonstrate that long-term exposure to fine particulate matter (PM2.5) from biomass combustion had no impact on cellular viability and proliferation but increased intracellular reactive oxygen species (ROS) levels in bronchial epithelial BEAS-2B cells. Exposure to PM2.5 induced the nuclear factor erythroid 2-related factor 2 (Nrf2) and mediated an anti-oxidative response, including enhanced levels of intracellular glutathione (GSH) and nuclear accumulation of heme oxygenase-1 (HO-1). Activation of Nrf2 was promoted by the c-Jun N-terminal kinase JNK1/2, but not p38 or Akt, which were also induced by PM2.5. Furthermore, cells exposed to PM2.5 acquired chemoresistance to doxorubicin, which was associated with inhibition of apoptosis and elevated levels of GSH in these cells. Our findings propose that exposure to PM2.5 induces molecular defense mechanisms, which prevent cellular damage and may thus explain the initially relative rare complications associated with PM2.5. However, consistent induction of pro-survival pathways may also promote the progression of diseases. Environmental conditions inducing anti-oxidative responses may have the potential to promote a chemoresistant cellular phenotype.

Abstract
The experimental data on the oral toxicity of nanostructured amorphous silica (SiO2), widely used in food supplements, pharmaceuticals, and cosmetics, in terms of its in vivo effect on the immune system, are contradictory. Therefore, this study aimed to assess the rat's immune function after SiO2 oral administration. In the first experiment, SiO2 was daily orally administered to Wistar rats for 92 days in doses of 0.1, 1.0, 10, and 100 mg/kg of body weight (bw). In the second 28-day experiment, SiO2 in a dose of 100 mg/kg bw was daily orally administered to rats parenterally immunized with the food allergen ovalbumin (OVA) for the reproduction of systemic anaphylaxis reaction. Together with integral indices, we assessed intestinal permeability to protein macromolecules; hematology; CD45RA+, CD3+, CD4+, CD8+, and CD161a+ cells; cytokines TNF-α, IL-6, and IL-10; and IgG to OVA. The results obtained showed that SiO2 has no effect on the severity of the anaphylactic reaction, but is capable inducing a toxic effect on the T-cell immune systems of rats. Estimated no observed adverse effect level NOAEL for SiO2 ranges up to 100 mg/kg bw in terms of its daily consumption for 1-3 months. Using SiO2 as a food additive should be the subject of regulation.

Abstract
Nano-silicate platelets (NSP), an exfoliated product from natural clays, have been validated for biosafety and as an effective supplement to alleviate mycotoxicosis. Since NSP induced noticeable cell death, we therefore investigated further the mechanism of cytotoxicity caused by NSP. Exposure to NSP impaired membrane integrity and caused cell death in a dose-dependent manner. Reactive oxygen species (ROS) generation other than of NADH oxidase origin, and subcellular interactions by internalized NSP also contributed to NSP-induced cell death. NSP persistently provoked receptor-interacting protein 1 Ser/Thr (RIP1) kinase and caspase 6 and 3/7 activation without altering caspase 8 activity and induced evident chromatolysis of necrosis in the later stage. These events proceeded along with increased ER stress and mitochondrial permeability, to final Cyt-C (Cytochrome C) release and AIF (apoptosis inducing factor) translocation, a hallmark of cell necroptosis. Fluorescent probing further manifested NSP traffic, mostly adherence on the cell surfaces, or via internalization, being compartmentalized in the nuclei, cytosols, and mitochondria. Pharmacological approaches with specific inhibitors suggested that endocytosis and particularly RIP1 kinase provocation mediate NSP-induced cell death independent of caspase activation. In conclusion, the necroptotic process contributes to most of the cell death induced by NSP due to membrane interactions/impaired integrity, ROS generation, and subcellular interactions by internalized NSP.

Abstract
Introduction Adoptive T-cell immunotherapy emerged as a powerful and promising cancer therapy, as the problem regarding the immuno-reaction between different donors and recipients can be avoided. However, this approach is challenging. After long cultivation and expansion under laboratory media conditions, T-cells are losing their viability and function due to immune checkpoint proteins, leading to decreased efficiency in killing cancer cells. Therefore, a new strategy to improve T-cell survival and function is needed. With the advantages of nanotechnology and the biocompatibility of silica-based material, silica nanocapsules (SiNCs) provide an ideal delivery system to transport therapeutic biomolecules to T-cells. Up to now, there is a lack of cellular uptake studies of nanocarriers towards T-cells. Methods We systematically studied the influence of various physicochemical properties such as sizes, core hydrophobicities, surface charges, and surface functionalities of SiNC for their impact on cellular uptake and toxicity in CD8+ T-cells by flow cytometry and confocal laser scanning microscopy. Cytokine secretion assay was performed using the enzyme-linked immunosorbent assay. To identify suitable uptake conditions for SiNCs into CD8+ T-cells, the impact of human serum in cell culture medium was also investigated. Results The major impact on cellular uptake and toxicity was found to be size- and dose-dependent. Smaller sizes of SiNCs than 100 nm caused significant toxicity to the cells. It was found that the formed protein corona reduced the toxicity of the SiNCs. However, it also inhibited their uptake. Conclusion Overall, we present a set of different criteria for a suitable design of nanocarriers and cell culture conditions, which need to be carefully considered for T-cell immunotherapy in vitro to facilitate uptake while avoiding toxicity.

Abstract
Some studies have shown that silicon dioxide nanoparticles (SiO2-NPs) can reach different regions of the brain and cause toxicity; however, the consequences of SiO2-NPs exposure on the diverse brain cell lineages is limited. We aimed to investigate the neurotoxic effects of SiO2-NP (0–100 µg/mL) on rat astrocyte-rich cultures or neuron-rich cultures using scanning electron microscopy, Attenuated Total Reflection-Fourier Transform Infrared spectroscopy (ATR-FTIR), FTIR microspectroscopy mapping (IQ mapping), and cell viability tests. SiO2-NPs were amorphous particles and aggregated in saline and culture media. Both astrocytes and neurons treated with SiO2-NPs showed alterations in cell morphology and changes in the IR spectral regions corresponding to nucleic acids, proteins, and lipids. The analysis by the second derivative revealed a significant decrease in the signal of the amide I (α-helix, parallel β-strand, and random coil) at the concentration of 10 µg/mL in astrocytes but not in neurons. IQ mapping confirmed changes in nucleic acids, proteins, and lipids in astrocytes; cell death was higher in astrocytes than in neurons (10–100 µg/mL). We conclude that astrocytes were more vulnerable than neurons to SiO2-NPs toxicity. Therefore, the evaluation of human exposure to SiO2-NPs and possible neurotoxic effects must be followed up.

Abstract
Silica nanoparticles (SiNPs) are used in a wide range of consumer products, engineering and medical applications, with likelihood of human exposure and potential health concerns. It is essential to generate toxicity information on SiNP forms and associated physicochemical determinants to conduct risk assessment on these new materials. To address this knowledge gap, we screened a panel of custom synthesized, well-characterized amorphous SiNPs pristine and surface-modified (-C3-COOH, -C11-COOH, -NH2, -PEG) of 5 different sizes: (15, 30, 50, 75, 100 nm) for their oxidative potential using an acellular assay. The assay is based on oxidation of dithiothreitol (DTT) by reactive oxygen species and can serve as a surrogate test for oxidative stress. These materials were characterized for size distribution, aggregation, crystallinity, surface area, surface modification, surface charge and metal content. Tests for association between oxidative potential of SiNPs and their physicochemical properties were carried out using analysis of variance and correlation analyses. These test results suggest that the size of amorphous SiNPs influenced their oxidative potential irrespective of the surface modification, with 15 nm exhibiting relatively higher oxidative potential compared to the other sizes. Furthermore, SiNP surface area, surface modification and agglomeration in solution also appeared to affect oxidative potential of these SiNPs. These findings indicate that physicochemical properties are critical in influencing the oxidative behaviour of amorphous SiNPs, with potential to trigger cellular oxidative stress and thus toxicity, when exposed. This information advances our understanding of potential toxicities of these amorphous SiNPs and supports risk assessment efforts and the design of safer forms of silica nanomaterials.

The unique surface and physicochemical properties of amorphous nanosilica supports advanced nano-biomolecular applications for various manufacturing, biotechnology, and healthcare industries including cosmetics, packaging, implants, drug delivery systems and cancer diagnostics. The increased technological and economic benefits of amorphous nanosilica, raises concerns regarding their adverse biological effects on humans. The cellular mechanisms underlying amorphous nanosilica internalization, evasion of biological barriers, inadvertent nano-bio interactions and unexpected long term exposure effects must be taken into consideration from the diverse ecosystems and human safety aspects. Recent research studies reveal cytotoxic, inflammatory and immunomodulatory effects of amorphous nanosilica particles. Our review focuses on studies demonstrating hazardous impact of amorphous nanosilica/bio-systems interface on the cellular and biochemical processes. The review further seeks to evaluate amorphous nanosilica-induced cytotoxicity, innate immune responses, inflammation and immune related dysfunctions, and discuss open research questions related to the use of amorphous nanosilica in biomedicine.

Abstract
Solid surface composites (SSCs) are a class of popular construction materials composed of aluminum trihydrate and acrylic polymers. Previous investigations have demonstrated that sawing SSC releases substantial airborne dusts, with a number-based geometric mean diameter of 1.05 µm. We reported that in mice, aspiration exposure to airborne SSC dusts induced symptoms of pulmonary inflammation at 24-h postexposure: neutrophilic influx, alveolitis, and increased lactate dehydrogenase (LDH) and pro-inflammatory cytokine levels in lavage fluid. The particles appeared to be poorly cleared, with 81% remaining at 14-day postexposure. The objective of this study was to determine the toxicity specifically of respirable particles on a model of human alveolar macrophages (THP-1). The relative toxicities of subfractions (0.07, 0.66, 1.58, 5.0, and 13.42 µm diameter) of the airborne particles were also determined. THP-1 macrophages were exposed for 24 h to respirable particles from sawing SSC (0, 12.5, 25, 50, or 100 µg/ml) or size-specific fractions (100 µg/ml). Exposure to respirable SSC particles induced THP-1 macrophage toxicity in a dose-dependent manner. Viability was decreased by 15% and 19% after exposure to 50 and 100 µg/ml SSC, respectively, which correlated with increased cell culture supernatant LDH activity by 40% and 70% when compared to control. Reactive oxygen species (ROS) production and inflammatory cytokines were increased in a dose-dependent manner. A size-dependent cytotoxic effect was observed in the cells exposed to subfractions of SSC particles. SSC particles of 0.07, 0.66, and 1.58 µm diameter killed 36%, 17%, and 22% of cells, respectively. These results indicate a potential for cytotoxicity of respirable SSC particles and a relationship between particle size and toxicity, with the smallest fractions appearing to exhibit the greatest toxicity.

Abstract
Airborne engineered nanomaterials (ENMs) can readily enter the human body through inhalation potentially leading to adverse health effects such as cardiovascular and pulmonary diseases. Our group has previously utilized and validated an integrated low flow system capable of generating and depositing airborne ENMs directly onto cells at an air-liquid interface (ALI). To further improve this ALI method for an even closer representation of the in vivo system, a co-culture model containing epithelial, endothelial and macrophage cell lines (A549, EA.hy 926, and THP-1 differentiated macrophages) was established and validated for testing ENMs toxicity. In the co-culture model, cells were exposed to citrate-capped gold (Au), 15% silver on silica (Ag-SiO2) and copper oxide (CuO) ENMs under the same protocol (4 h ALI exposure with a target concentration of 3.5 mg/m3) and compared to responses with A549 cells only or THP-1 differentiated cells only. The toxicological profile was assessed by measuring cell viability, reactive oxygen species (ROS) production, lactate dehydrogenase (LDH) release, and interleukin (IL)-8 concentration. Results showed that 15% Ag-SiO2 induced more oxidative stress-related toxicity in the co-culture than in A549 cells alone. Both 15% Ag-SiO2 and CuO exposure produced significantly higher levels of IL-8 in the co-culture compared with A549 cells alone. Citrate-capped Au was largely inert. Further exposures of CuO on macrophages alone provided evidence of cell-cell interaction in the co-culture model. In addition, the co-culture model exhibited a similar response to primary human bronchial epithelial cells in terms of ROS and IL-8 responses after CuO exposure, suggesting a more advanced refinement of the conventional model for in vitro inhalation study.

Abstract
Despite the progress in nanotechnology for biomedical applications, great efforts are still being employed in optimizing nanoparticle (NP) design parameters to improve functionality and minimize bionanotoxicity. In this study, we developed CdSe/CdS/ZnS core/shell/shell quantum dots (QDs) that are compact ligand-coated and surface-functionalized with an HIV-1-derived TAT cell-penetrating peptide (CPP) analog to improve both biocompatibility and cellular uptake. Multiparametric studies were performed in different mammalian and murine cell lines to compare the effects of varying QD size and number of surface CPPs on cellular uptake, viability, generation of reactive oxygen species, mitochondrial health, cell area, and autophagy. Our results showed that the number of cell-associated NPs and their respective toxicity are higher for the larger QDs. Meanwhile, increasing the number of surface CPPs also enhanced cellular uptake and induced cytotoxicity through the generation of mitoROS and autophagy. Thus, here we report the optimal size and surface CPP combinations for improved QD cellular uptake.

Abstract
Hepatocellular carcinoma is the most common type of primary malignancy in the liver and one of the most common types of cancer worldwide. Its readily increasing mortality rate highlights the urgent need for the development of efficient therapeutic strategies. Tyrosine kinase inhibitors (TKIs) such as sorafenib and sunitinib are used as efficient angiogenesis inhibitors for this purpose. However, despite their pharmacological effects, their transfer into clinical practice is characterized by their poor aqueous solubility and accumulation in off-target tissues, resulting in unfavorable side effects. Here, we report a nanocomposite made of amine-functionalized mesoporous silica nanocomposites (MSNs) that are surface-coated with cerium oxide nanoparticles (CNPs) for the controlled delivery and release of TKIs. Amine-functionalized MSNs were prepared using a sol-gel method and loaded with TKIs. To trap drug molecules into the mesoporous structure, CNPs were covalently conjugated to the surface of MSNs. The synthesis and functionalization steps were controlled using different characterization methods, confirming the desired morphology and structure, the identity of functional groups on the surface, successful coating, and appropriate loading efficiency. Under physiological conditions, CNP-capped MSNs demonstrated a sustained drug release over time as a result of CNPs' gatekeeping effect on the payloads. Strong cellular interactions with different liver cancer cells and enhanced cellular uptake were also observed in vitro for the gate-capped MSNs. Internalization of nanocomposites induced cell death via the production of reactive oxygen species, and subsequent activation of apoptosis pathways. This study demonstrates that gate-capped MSNs are promising chemotherapeutic vehicles characterized by a sustained drug release profile and high cellular internalization.

Abstract
Due to mass production and extensive use, the potential adverse health effects of amorphous silica nanoparticles (ASiNPs) have received a significant attention from the public and researchers. However, the relationship between physicochemical properties of ASiNPs and their health effects is still unclear. In this study, we manufactured two types of ASiNPs of different diameters (20 and 50 nm) and compared the toxic response induced in rats after intratracheal instillation (75, 150 or 300 μg/rat). There were no dose-related differences in mortality, body weight gain or organ weight between the groups. However both types of ASiNPs significantly decreased the proportion of neutrophils in male rats, whereas the levels of hemoglobin and hematocrit were markedly reduced only in female rats instilled with 20 nm-ASiNPs. ASiNPs-induced lung tissue damage seemed to be more evident in the 20 nm ASiNP-treated group and in female rats than male rats. Similarly, expression of caveolin-1 and matrix metalloproteinase-9 seemed to be most notably enhanced in female rats treated with 20 nm-ASiNPs. The total number of bronchial alveolar lavage cells significantly increased in rats instilled with 20 nm-ASiNPs, accompanying a decrease in the proportion of macrophages and an increase in polymorphonuclear leukocytes. Moreover, secretion of inflammatory mediators clearly increased in human bronchial epithelial cells treated with 20 nm-ASiNPs, but not in those treated with 50 nm-ASiNPs. These results suggest that pulmonary effects of ASiNPs depend on particle size. Sex-dependent differences should also be carefully considered in understanding nanomaterial-induced adverse health effects.

Abstract
This study assessed the gaseous and particulate emissions, as well as the toxicological properties of particulate matter (PM) from a flex fuel vehicle equipped with a wall-guided gasoline direct injection engine over triplicates cold-start and hot-start LA92 cycles. The vehicle was operated on a Tier 3 E10 fuel, an E10 fuel with higher levels of aromatics than the Tier 3 E10, an E30, and an E78 blend. Total hydrocarbon (THC), non-methane hydrocarbon (NMHC), carbon monoxide (CO), particulate emissions, and gaseous toxics (of benzene, toluene, ethylbenzene, xylenes (BTEX), and 1,3-butadiene) reduced for E30 and E78 blends compared to both E10 fuels. Formaldehyde and acetaldehyde emissions substantially increased with the higher ethanol blends. The high aromatic E10 fuel increased the emissions of THC, NMHC, particulates, and BTEX compared to the Tier 3 E10 fuel and the higher ethanol blends, as well as showed higher concentrations of accumulation mode particles. The GDI PM did not exhibit any measurable mutagenicity at the PM concentrations tested. Cytotoxicity varied only within a small range and concentrations of PM, eliciting a cytotoxic response similar to those by ambient aerosol. The outcomes of our two measures of PM oxidative potential (macrophage ROS and DTT) were significantly correlated, with the E78 blend exhibiting the least oxidative potential and the E30 the greatest. Gene expression analysis at both the mRNA and protein level indicates that there is the potential for GDI PM emissions to contribute to inflammation and etiology of disease such as asthma, and in contrast to the ROS and DTT outcomes, the E78 fuel PM exhibited the greatest potential to elicit pro-inflammatory cytokine (TNFα) production. Overall, the trends in toxicity emission rates (activity/mi) across the ethanol blends was driven primarily by PM mass emission rate contrasts and only secondarily by the differences in intrinsic toxicity of the PM.

Abstract
Introduction: Engineered nanoparticles (ENPs) are one of the most widely used types of nanomaterials. Recently, ENPs have been shown to cause cellular damage by inducing ROS (reactive oxygen species) both directly and indirectly, leading to the changes in DNA methylation levels, which is an important epigenetic mechanism. In this study, we investigated the effect of ENP-induced ROS on DNA methylation. Materials and methods: Human embryonic kidney and human keratinocyte (HaCaT) cells were exposed to three different types of ENPs: gold nanoparticles, silicon nanoparticles (SiNPs), and chitosan nanoparticles (CSNPs). We then evaluated the cytotoxicity of the ENPs by measuring cell viability, morphology, cell apoptosis, cell proliferation, cell cycle distribution and ROS levels. Global DNA methylation levels was measured using 5-methylcytosine immunocytochemical staining and HPLC analysis. DNA methylation levels of the transposable elements, long interspersed element-1 (LINE-1) and Alu, were also measured using combined bisulfite restriction analysis technique. DNA methylation levels of the TEs LINE-1 and Alu were also measured using combined bisulfite restriction analysis technique. Results: We found that HaCaT cells that were exposed to SiNPs exhibited increased ROS levels, whereas HaCaT cells that were exposed to SiNPs and CSNPs experienced global and Alu hypomethylation, with no change in LINE-1 being observed in either cell line. The demethylation of Alu in HaCaT cells following exposure to SiNPs and CSNPs was prevented when the cells were pretreated with an antioxidant. Conclusion: The global DNA methylation that is observed in cells exposed to ENPs is associated with methylation of the Alu elements. However, the change in DNA methylation levels following ENP exposure is specific to particular ENP and cell types and independent of ROS, being induced indirectly through disruption of the oxidative defense process.

Abstract
Due to a wide range of applications in industrial fields, engineered nanomaterials (ENMs) have a high potential to enter the soil. The soil's major component of clay likely dictates the fate and transport of ENMs in the subsurface. Currently, few studies are available on the fate and transport of nanoparticle silica (nSiO2) in the presence of clay particles. Therefore, the sedimentation and transport of nSiO2 with two representative clays (montmorillonite (M) and kaolin (K)) in porous media were investigated in monovalent (Na+) and divalent (Ca2+) ion solutions with multiple characterizations including SEM/TEM-EDX, zeta potentials, particle sizes and colloid transport modeling. It was shown that nSiO2-nSiO2 homoaggregates and nSiO2-K (or M) heteroaggregates dominated in the nSiO2-clay nanoaggregate suspension. A distinct decrease in the stability and transport of nSiO2-M (or K) in NaCl solution and an increase in CaCl2 occurred when M or K was added to the nSiO2 suspension at pH 6.0. This was attributed to the faster settlement of the individual M or K in NaCl vs. the better stability in CaCl2 (compared to nSiO2 alone). Particularly, more negative individual M platelets occurred in the high NaCl solution until extensive flocculated structures built up, which contributed to the faster deposition of nSiO2-M compared to nSiO2-K, even though the nSiO2-M was more negatively charged. Comparably, the effect of M and K on the fate and transport of nSiO2 almost disappeared at pH 9.0. The values of the first-order attachment/detachment rate coefficients (k1/k1d) and first-order straining coefficient (k2) obtained from two-site kinetic attachment model fitting are responsible for the deposition of nSiO2-clay nanoaggregates in sand. This study suggests potential groundwater contamination due to the clay-facilitated transport of ENMs in calcareous soil.

Abstract
Gut immune system homeostasis involves diverse structural interactions among resident microbiota, the protective mucus layer, and a variety of cells (intestinal epithelial, lymphoid, and myeloid). Due to the substantial surface area in direct contact with an "external" environment and the diversity of xenobiotic, abiotic, and self-interactions coordinating to maintain gut homeostasis, there is enhanced potential for the generation of endogenous danger signals when this balance is lost. Here, we focus on the potential generation and reception of damage in the gut resulting from exposure to nanoparticles (NPs), common food and drug additives. Specifically, we describe recent evidence in the literature showing that certain NPs are potential generators of damage-associated molecular patterns, as well as potential immune-stimulating molecular patterns themselves.

Abstract
Tattoo inks represent a growing market in the world economy, but this growth is associated with an increase in reports of adverse effects caused by the use of this product. In this study, four commercial tattoo inks (blue, green, red and black) were studied to characterize the composition and particle size and identify possible in vivo and in vitro toxicological effects on Daphnia magna and HaCaT cells, respectively. Compositional analysis confirmed the functional groups in the vehicles and organic pigments. The presence of nanoparticles was confirmed by image analysis. The toxicological evaluation indicated distinct results for blue and green inks for the parameters tested, despite the presence of similar levels of metals. The red ink, followed by the green, presented the highest toxicity, which may be related to pigments containing azo compounds and not to the metal fraction. Black ink was found to be the safest toxicologically. This paper provides an overview of the composition of tattoo inks and their toxicological effects in epidermal cells and in the environment.

Cellular Responses of Industrially Relevant Silica Dust on Human Glial Cells In Vitro. Int J Mol Sci 2019; 20:ijms20020358.

Abstract
Despite the rigorous emission control measures in the ferroalloy industry, there are still emissions of dust during the production of various alloys. Dust particles were collected from laboratory scale processes where oxide particulate matter was formed from liquid silicon (metallurgical grade). The dust was produced in a dry air atmosphere to mimic industrial conditions. To investigate possible effects of ultrafine dust on the central nervous system, a human astrocytic cell line was employed to investigate inflammatory effects of particles as astrocytes play a number of active and neuron supporting roles in the brain. Toxicity on the astrocytes by amorphous silica generated in laboratory scale was compared to crystalline macro-sized silica using several doses to determine toxicological dose response curves. The cell viability experiments indicated that low particle doses of amorphous silica induced a small nonsignificant reduction in cell viability compared to crystalline silica which led to increased levels of toxicity. The gene expression of amyloid precursor protein (APP), a biomarker of neurodegenerative disease, was affected by particle exposure. Furthermore, particle exposure, in a dose-and time-dependent manner, affected the ability of the cells to communicate through gap junction channels. In conclusion, in vitro studies using low doses of particles are important to understand mechanisms of toxicity of occupational exposure to silica particles. However, these studies cannot be extrapolated to real exposure scenarios at work place, therefore, controlling and keeping the particle exposure levels low at the work place, would prevent potential negative health effects.

Abstract
Several studies have suggested that air pollutants combine exposure have greater adverse effects. However, limited studies were available on the combined toxicity of silica nanoparticles (SiNPs) and benzo[a]pyrene (B[a]P). The study was to evaluate the toxic effect and mechanisms of low-dose exposure of SiNPs, B[a]P and co-exposure in zebrafish embryos. In this study, zebrafish embryos received intravenous microinjection of SiNPs and B[a]P, and then was used to select differentially expressed genes by microarray analysis. Multiple bioinformatics analyses and STC analysis were done to identify key genes, pathways and biological processes and the expression trend of genes in each group. 1) 3065 differentially expressed genes were identified in zebrafish embryos. 2) These differentially expressed genes were involved in multiple biological processes and cellular processes such as immunity, response to stimuli, cell proliferation, adhesion, signaling transduction, and embryonic development. 3) Dynamic Gene Network analysis was used to identify a subgroup of 26 core genes that involved in multiple biological processes and cellular processes. 4) Pathway analysis and Signal-net analysis indicated that the MAPK signaling pathway, calcium signaling pathway, p53 signaling pathway, PI3k/Akt signaling pathway, and several pathways associated with immune response were the most prominent significant pathways induced by co-exposure of SiNPs and B[a]P in zebrafish embryos. Our study demonstrated that the molecular actions of co-treated with SiNPs and B[a]P on the immune system, inflammatory process and cardiovascular development had more severe toxicity than single exposure.

Abstract
Silicon-based materials and their oxides are widely used in drug delivery, dietary supplements, implants and dental fillers. Silica nanoparticles (SiNPs) interact with immunocompetent cells and induce immunotoxicity. However, the toxic effects of SiNPs on the immune system have been inadequately reviewed. The toxicity of SiNPs to the immune system depends on their physicochemical properties and the cell type. Assessments of immunotoxicity include determining cell dysfunctions, cytotoxicity and genotoxicity. This review focuses on the immunotoxicity of SiNPs and investigates the underlying mechanisms. The main mechanisms were proinflammatory responses, oxidative stress and autophagy. Considering the toxicity of SiNPs, surface and shape modifications may mitigate the toxic effects of SiNPs, providing a new way to produce these nanomaterials with less toxic impaction.

Abstract
CuO nanoparticles (CuO-NPs) serve several important functions in human life, particularly in the fields of medicine, engineering, and technology. These nanoparticles have been utilized as catalysts, semiconductors, sensors, gaseous and solid ceramic pigments, and magnet rotatable devices. Further use for CuO-NPs has been employed in the pharmaceutical industry especially in the production of anti-microbial fabric treatments or prevention of infections caused by Escherichia coli and methicillin-resistant Staphylococcus aureus. Two key potential routes of exposure to CuO-NPs exist through inhalation and skin exposure. Toxicity of these nanoparticles has been reported in various studies; however, no study as of yet has investigated the complete cellular mechanisms involved in CuO-NPs toxicity on human cells. The aim of this study was to determine the cytotoxicity of CuO-NPs on human blood lymphocytes. Blood lymphocytes were obtained from healthy male subjects through the use of Ficoll polysaccharide subsequently by gradient centrifugation. The following parameters were assayed in blood lymphocytes after a 6-h incubation with different concentrations of CuO-NPs: cell viability, reactive oxygen species (ROS) formation, lipid peroxidation, cellular glutathione levels, and mitochondrial and lysosomal damage. Our results demonstrate that CuO-NPs, in particular, decreased cell viability in a concentration-dependent manner and the IC50 determined was 382 μM. CuO-NP cytotoxicity was associated with significant increase at intracellular ROS level and loss of mitochondrial membrane potential and lysosomal membrane leakiness. Hence, CuO-NPs are shown to effectively induce oxidative stress in addition to inflict damage on mitochondria and lysosomes in human blood lymphocytes.

Abstract
BACKGROUND Immunmodulation combined with chemotherapy has emerged as an alternative to treat infections. The study evaluates immunomodulatory properties of a Leishmania recombinant protein (rA6) in activating macrophages and clearing intracellular parasites. METHODS The rA6 from a previously identified cDNA clone was analyzed for inducing the production of nitric oxide (NO) and reactive oxygen species (ROS) in macrophages, post and prior to infection with promastigotes by Griess method and flow cytometry. Phagocytosis and killing by treated macrophages was evaluated using Staphylococcus aureus as an index organism. Intracellular clearance of PKH67-labeled parasites from treated macrophages was assessed flowcytometrically. Combined effect of rA6 with miltefosine/AmBisome in reducing intracellular amastigotes was examined microscopically. RESULTS Treatment with rA6 post infection caused increased production of NO with increased number of macrophages producing NO and ROS coupled with enhanced phagocytic and killing capacity. Antigen stimulated macrophages expressed high level of iNOS and TNF-α mRNA. It synergized with miltefosine and AmBisome and facilitated early clearance of intracellular amastigotes at sub-optimal drug doses. CONCLUSION The study demonstrates immunomodulatory potential of rA6 and presents first evidence on synergism between rA6 and anti-leishmanial drugs, thus placing it as a promising candidate for adjunct therapy.

Abstract
Little is known about the global gene expression profile of macrophages in response to changes in size and porosity of silica nanoparticles (SNPs). Spherical nonporous SNPs of two different diameters, and mesoporous spherical SNPs with comparable size were characterized. Reactive oxygen species, mitochondrial membrane potential, lysosome degradation capacity, and lysosome pH were measured to evaluate the influence of nonporous and mesoporous SNPs on mitochondrial and lysosomal function. RNA-sequencing was utilized to generate transcriptional profiles of RAW264.7 macrophages exposed to non-toxic SNP doses. DESeq2, limma, and BinReg2 software were used to analyze the data based on both unsupervised and supervised strategies to identify genes with greatest differences among NP treatments. Utilizing GATHER and DAVID software, possible induced pathways were studied. We found that mesoporous silica nanoparticles are capable of altering gene expression in macrophages at doses that do not elicit acute cytotoxicity, while gene transcription was minimally affected by nonporous SNPs.

Abstract
Due to the potential negative impact of nano silica (nSiO2) on human's health and living environments, it is important to investigate their transport in soil environments. Hydrochars has been widely used in agricultural soil and phosphate (P) is an important nutrient, thus the aggregation and transport of nSiO2 in saturated sand columns were investigated in single and binary systems of hydrochars and P. The experimental results showed that the nSiO2 aggregates can be restablized by the adsorption of P or the attachment of hydrochars at high IS (>100 mM) and low pH (<7.0). Accordingly, the transport of nSiO2 in sand columns is enhanced due to the smaller particle size. However, the nSiO2 presents the distinct surface characteristics at pH > 7.0 from that at pH < 7.0. Thus, nSiO2 has a better dispersivity in 300 mM NaCl solution at high pH (9.0). Nevertheless, their deposition to sands becomes pronounced in the presence of hydrochars and/or P. In particular, the formation of nSiO2-hydrochar-Phosphate clusters associated with the larger size mainly contributes to the enhancement of nSiO2 retention in sand columns during the wide pH range, when hydrochars and P coexist in suspensions. The two-site dynamic model fitting results showed that the reversible retention is related to k2 (First-order straining coefficient on site 2). The results in this study will provide the theoretical basis for assessing the retention of nSiO2 in soil environment with the presence of hydrochars and phosphate.

Abstract
Large-scale production and use of amorphous silica nanoparticles (SiNPs) have increased the risk of human exposure to SiNPs, while their health effects remain unclear. In this review, scientific papers from 2010 to 2016 were systematically selected and sorted based on in vitro and in vivo studies: to provide an update on SiNPs toxicity and to address the knowledge gaps indicated in the review of Napierska (Part Fibre Toxicol 7:39, 2010). Toxicity of SiNPs in vitro is size, dose, and cell type dependent. SiNPs synthesized by wet route exhibited noticeably different biological effects compared to thermal route-based SiNPs. Amorphous SiNPs (particularly colloidal and stöber) induced toxicity via mechanisms similar to crystalline silica. In vivo, route of administration and physico-chemical properties of SiNPs influences the toxicokinetics. Adverse effects were mainly observed in acutely exposed animals, while no significant signs of toxicity were noted in chronically dosed animals. The correlation between in vitro and in vivo toxicity remains less well established mainly due to improper-unrealistic-dosing both in vitro and in vivo. In conclusion, notwithstanding the multiple studies published in recent years, unambiguous linking of physico-chemical properties of SiNPs types to toxicity, bioavailability, or human health effects is not yet possible.
