Abstract
Zinc oxide nanoparticles (ZnO NPs) are widely used in many fields due to their unique physicochemical properties. However, the renal toxicity of ZnO NPs and the underlying mechanisms have not been well studied. We found that ZnO NPs induced injury in human renal proximal tubular epithelial cells (HK-2) in a dose- and size-dependent manner, as revealed by CCK-8, LDH and Annexin V-FITC assays. Mechanistically, ZnO NPs promoted oxidative stress and mitochondrial damage by generating ROS and induced apoptosis in HK-2 cells, as evidenced by the upregulation of Bax and Caspase 3 and downregulation of Beclin 1. In vivo, ZnO NPs induced tubular epithelial cell apoptosis and increased serum creatinine, serum urea nitrogen, and urinary protein in mice, suggesting damage to renal structure and function. These findings clarified our understanding of the biological mechanisms underlying ZnO NP-induced renal tubular epithelial cell injury and contributed to estimating the risk of ZnO NPs to the kidney.

Review of Zinc Oxide Nanoparticles: Toxicokinetics, Tissue Distribution for Various Exposure Routes, Toxicological Effects, Toxicity Mechanism in Mammals, and an Approach for Toxicity Reduction. Biol Trace Elem Res 2024; 202:9-23.

Abstract
Zinc oxide (ZnO) nanoparticles (NPs) are widely used as a sunscreen, antibacterial agent, dietary supplement, food additive, and semiconductor material. This review summarizes the biological fate following various exposure routes, toxicological effects, and toxicity mechanism of ZnO NPs in mammals. Furthermore, an approach to reduce the toxicity and biomedical applications of ZnO NPs are discussed. ZnO NPs are mainly absorbed as Zn2+ and partially as particles. Regardless of exposure route, elevated Zn concentration in the liver, kidney, lungs, and spleen are observed following ZnO NP exposure, and these are the target organs for ZnO NPs. The liver is the main organ responsible for ZnO NP metabolism and the NPs are mainly excreted in feces and partly in urine. ZnO NPs induce liver damage (oral, intraperitoneal, intravenous, and intratracheal exposure), kidney damage (oral, intraperitoneal, and intravenous exposure) and lung injury (airway exposure). Reactive oxygen species (ROS) generation and induction of oxidative stress may be a major toxicological mechanism for ZnO NPs. ROS are generated by both excess Zn ion release and the particulate effect resulting from the semiconductor or electronic properties of ZnO NPs. ZnO NP toxicity can be reduced by coating their surface with silica, which prevents Zn2+ release and ROS generation. Due to their superior characteristics, ZnO NPs are expected to be used for biomedical applications, such as bioimaging, drug delivery, and anticancer agents, and surface coatings and modification will expand the biomedical applications of ZnO NPs further.

Abstract
The exogenous excitation requirement and electron-hole recombination are the key elements limiting the application of catalytic therapies. Here a tumor microenvironment (TME)-specific self-triggered thermoelectric nanoheterojunction (Bi0.5Sb1.5Te3/CaO2 nanosheets, BST/CaO2 NSs) with self-built-in electric field facilitated charge separation is fabricated. Upon exposure to TME, the CaO2 coating undergoes rapid hydrolysis, releasing Ca2+, H2O2, and heat. The resulting temperature difference on the BST NSs initiates a thermoelectric effect, driving reactive oxygen species production. H2O2 not only serves as a substrate supplement for ROS generation but also dysregulates Ca2+ channels, preventing Ca2+ efflux. This further exacerbates calcium overload-mediated therapy. Additionally, Ca2+ promotes DC maturation and tumor antigen presentation, facilitating immunotherapy. It is worth noting that the CaO2 NP coating hydrolyzes very slowly in normal cells, releasing Ca2+ and O2 without causing any adverse effects. Tumor-specific self-triggered thermoelectric nanoheterojunction combined catalytic therapy, ion interference therapy, and immunotherapy exhibit excellent antitumor performance in female mice.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 865:161242. [PMID: 36587696 DOI: 10.1016/j.scitotenv.2022.161242] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 12/12/2022] [Accepted: 12/24/2022] [Indexed: 06/17/2023]
Abstract
Zinc oxide nanoparticles (ZnO NPs) have drawn serious concerns about their biotoxicity due to their extensive applications in biological medicine, clinical therapeutic, daily chemical production, food and agricultural additives. In our present study, we clarified hepatotoxic mechanism of ZnO NPs through investigating the crosstalk between autophagy and pyroptosis, a remaining enigma in hepatocyte stimulated by ZnO NPs. Based on the effects of autophagy intervention by Rapamycin (Rap) and 3-Methyladenine (3-MA), and the observation of pyroptosis morphology and related indexes, the autophagy and pyroptosis simultaneously initiated by ZnO NPs were interrelated and the autophagy characterized by autophagosome production and increased expression of autophagy proteins was identified as a protective response of ZnO NPs against pyroptosis. According to the analysis of protein expression and fluorescence localization, the NLRP3 inflammasome assemble and the classical Caspase-1/GSDMD-dependent pyroptosis induced by ZnO NPs was modulated by autophagy. In this process, the adjustment of TFEB expression and nuclear translocation by gene knockout and gene overexpression, further altered the tendency of ZnO NPs-induced pyroptosis via the regulation of autophagy and lysosomal biogenesis. The knockout of TFEB gene exacerbated the pyroptosis via autophagy elimination and lysosome inhibition. While the alleviation of NLRP3 generation and pyroptosis activation was observed after treatment of TFEB gene overexpression. Additionally, the siRNA interference confirmed that TRAF-6 was involved in the TFEB-mediated global regulation of autophagy-lysosome-pyroptosis in response to ZnO NPs. Accordingly, pyroptosis induced by ZnO NPs in hepatocyte could be significantly avoided by TFEB-regulated autophagy and lysosome, further providing new insights for the risk assessment and therapeutic strategy.

Abstract
Zinc oxide nanoparticles (ZnO NPs) have been widely used in the fields of daily necessities, clinical diagnosis, drug delivery and agricultural production. The improper use of ZnO NPs could pose a risk to ecological environment and public health. Liver has been known as a critical toxic target of ZnO NPs. However, the question whether ZnO NPs lead to hepatocyte death through pyroptosis has not been answered yet, and the effect of oxidative stress on ZnO NPs-induced pyroptosis remains a mystery. We revealed that ZnO NPs disrupted zinc homeostasis and induced oxidative stress impairment in rat liver. Meanwhile, ZnO NPs triggered the assembly of NLRP3-ASC-Caspase-1 inflammatory complex and pyroptosis in both rat liver and HepG2 cells, further causing the activation of GSDMD, promoting the leakage of inflammatory cytokines including IL-1β and IL-18. Importantly, the inhibition of oxidative stress was found to provide protection against pyroptosis in hepatocyte exposed to ZnO NPs. We identified a novel mechanism of liver damage induced by ZnO NPs, demonstrating the activation of canonical Caspase-1-dependent pyroptosis pathway and clarifying the protection of antioxidation against pyroptosis damage. Our discovery provided a support for risk assessment of ZnO NPs and target exploration for clinical treatment related to pyroptosis.

Abstract
Zinc oxide nanomaterial is a potential material in the field of cancer therapy. In this study, zinc oxide nanospheres (ZnO-NS) were synthesized by Sol-gel method using yeast extract as a non-toxic bio-template and investigated their physicochemical properties through various techniques such as FTIR, XR, DLS, and TEM. Furthermore, free zinc ions released from the zinc oxide nanosphere suspended medium were evaluated by using the ICP-AS technique. Therefore, the cytotoxicity of ZnO nanospheres and released Zn ions on both HuH7 and Vero cells was studied using the MTT assay. The data demonstrated that the effectiveness of ZnO nanospheres on HuH7 was better than free Zn ions. Similarly, ZnO-Ns were significantly more toxic to HuH7 cell lines than Vero cells in a concentration-dependent manner. The cell cycle of ZnO-Ns against Huh7 and Vero cell lines was arrested at G2/M. Also, the apoptosis assay using Annexin-V/PI showed that apoptosis of HuH7 and Vero cell lines by ZnO nanospheres was concentration and time-dependent. Caspase 3 assay results showed that the apoptosis mechanism may be intrinsic and extrinsic pathways. The mechanism of apoptosis was determined by applying the RT-PCR technique. The results revealed significantly up-regulated Bax, P53, and Cytochrome C, while the Bcl2 results displayed significant down-regulation and the western blot data confirmed the RT-PCR data. There is oxidative stress of the ZnO nanospheres and free Zn+2 ions. Results indicated that the ZnO nanospheres and free Zn+2 ions induced oxidative stress through increasing reactive oxygen species (ROS) and lipid peroxidation. The morphology of the HuH7 cell line after exposure to ZnO nanospheres at different time intervals revealed the presence of the chromatin condensation of the nuclear periphery fragmentation. Interestingly, the appearance of canonical ultrastructure features of apoptotic morphology of Huh7, Furthermore, many vacuoles existed in the cytoplasm, the majority of which were lipid droplets, which were like foamy cells. Also, there are vesicles intact with membranes that are recognized as swollen mitochondria.

Abstract
Nanotechnology allows for a greater quality of life, but may also cause environmental and organismic harm. Zinc oxide nanoparticles (ZnONPs) are one of the most commonly used metal oxide nanoparticles for commercial and industrial products. Due to its extensive use in various fields, there has already been much concern raised about the environmental health risks of ZnONPs. Many studies have investigated the toxicological profile of ZnONPs in zebrafish embryonic development; however, the specific characteristics of ZnONPs in zebrafish embryonic/larval developmental damage and their molecular toxic mechanisms of liver development are yet to be fully elucidated. This study aimed to reveal the hazard ranking of different surface modifications of ZnONPs on developing zebrafish and the toxicological mechanisms of these modified ZnONPs in liver tissue. The ~30 nm ZnONPs with amino- (NH2- ZnONPs) or carboxyl- (COOH-ZnONPs) modification were incorporated during the embryonic/larval stage of zebrafish. Severe toxicity was observed in both ZnONP groups, especially NH2-ZnONPs, which presented a higher toxicity in the low concentration groups. After prolonging the exposure time, the long-term toxicity assay showed a greater retardation in body length of zebrafish in the NH2-ZnONP group. Response data from multiple toxicity studies was integrated for the calculation of the EC50 values of bulk ZnO and ZnONPs, and the hazard levels were found to be decreasing in the order of NH2-, COOH-ZnONPs and bulk ZnO. Notably, NH2-ZnONPs induced ROS burden in the developing liver tissue, which activated autophagy-related gene and protein expression and finally induced liver cell apoptosis to reduce liver size. In conclusion, our findings are conducive to understanding the hazard risks of different surface modifications of ZnONPs in aquatic environments and will also be helpful for choosing the type of ZnONPs in future industrial applications.

Abstract
Zinc oxide nanoparticles (ZnO NPs) with high bioavailability and excellent physicochemical properties are gradually becoming commonplace as a substitute for conventional ZnO materials. The present study aimed to investigate the hepatotoxicity mechanism of ZnO NPs and traditional non-nano ZnO particles, both in vivo and in vitro, and identify the differences in their toxic effects. The results showed that the extent and conditions of zinc ion release from ZnO NPs were inconsistent with those of ZnO. The RNA-seq results revealed that the expression quantity of differentially expressed genes (DEGs) and differentially expressed transcripts (DETs) affected by ZnO NPs was more than in ZnO, and the overall differences in genes or transcripts in the ZnO NPs group were more pronounced than in the ZnO group. Furthermore, the cell inactivation, oxidative stress, mitochondrial damage, and intracellular calcium overload induced by ZnO NPs were more serious than ZnO in HepG2 cells. Moreover, compared with traditional ZnO, the rat liver damage induced by ZnO NPs was more significant, with evidence of higher AST and ALT levels, weaker antioxidant capacity, and more serious histopathological damage (p < 0.05). In summary, the hepatotoxicity of ZnO NPs was more serious than that of conventional ZnO, which is helpful to understand the hepatotoxicity mechanism of Zn compounds in different states and improve the risk assessment of novel nano ZnO products in a variety of applications.

Abstract
In recent years, with the widespread use of zinc oxide (ZnO) nanoparticles (NPs), more and more attentions are being given to its biological toxicity, the toxicity of ZnO NPs under different exposure methods is necessary to investigate. In this study, we prepared two ZnO dispersions
with different particle sizes, namely small-size ZnO (S-ZnO) and Bigsize ZnO (B-ZnO), using polycarboxylic acid as dispersant. Mice were poisoned by intravenous injection and inhalation, respectively. The respiration coefficient, superoxide dismutase (SOD), Zn content in the organs of the
mice were detected. It was discovered that ZnO NPs with smaller particle diameter can cause more serious toxicity in vivo after intravenous exposure and respiratory exposure. In addition, the mice showed symptoms of dyspnea after respiratory exposure and a massive number of fibroblasts
were found in the alveolar structure of the lungs. In the intravenous injection group, the content of Zn in the liver and spleen of mice increased significantly, resulting in organ edema, and the organ coefficient of mice increased. Finally, the increase of GSH/GSSG indicated that cells were
regulated under the antioxidant mechanism, which accelerated the removal of H2O2 from cells. In addition, the increase of GSH+GSSG content also indicated that ZnO NPs stimulated the creation of reactive oxygen species (ROS) in organs of experimental animals.

Abstract
Toxicity tests in rodents are still considered a controversial topic concerning their ethical justifiability. The chick embryo chorioallantoic membrane (CAM) assay may offer a simple and inexpensive alternative. The CAM assay is easy to perform and has low bureaucratic hurdles. At the same time, the CAM assay allows the application of a broad variety of analytical methods in the field of nanotoxicological research. We evaluated the CAM assay as a methodology for the determination of nanotoxicity. Therefore we calculated the median lethal dose (LD50), performed in vivo microscopy and immunohistochemistry to identify organ-specific accumulation profiles, potential organ damage, and the kinetics of the in vivo circulation of the nanoparticles. Zinc oxide nanoparticles were intravascularly injected on day 10 of the egg development and showed an LD50 of 17.5 µM (1.4 µg/mLeggcontent). In comparison, the LD50 of equivalent amounts of Zn2+ was 4.6 µM (0.6 µg/mLeggcontent). Silica encapsulated ZnO@SiO2 nanoparticles conjugated with fluorescein circulated in the bloodstream for at least 24 h. Particles accumulated mostly in the liver and kidney. In immunohistochemical staining, organ damage was detected only in liver tissue after intravascular injection of zinc oxide nanoparticles in very high concentrations. Zinc oxide nanoparticles showed a different pharmacokinetic profile compared to Zn2+ ions. In conclusion, the CAM assay has proven to be a promising methodology for evaluating nanotoxicity and for the assessment of the in vivo accumulation profiles of nanoparticles. These findings may qualify the methodology for risk assessment of innovative nanotherapeutics in the future.

Abstract
Use of nano-sized materials to design novel delivery systems is actually a double-edged sword regarding the enhancement of absorption and bioavailability of encapsulated bioactives as well as the unpredictable phenomena inside the living cells causing health concerns. So, comprehensive investigations on the use of nanomaterials in foods and their biological fate are needed. To reach this goal, both in vitro and in vivo techniques have been extensively applied. Besides the in vitro models such as cell culture and yeast/bacteria, different live animal models like mice, rat, Drosophila melanogaster, Caenorhabditis elegans, Zebrafish and dog can be applied to study bioavailability and safety of nanodelivery systems. However, considering the low correlation between the achieved results of in vitro and in vivo assays, in vivo tests are the first priority due to providing a real physiological condition. On the other hand, uncorrelated results by in vivo assays represent a serious problem to compare them. To defeat the issues in setting an in vivo research for the nanodelivery systems, all restrictions and FDA regulations is likely to be considered to improve the assays authenticity. This review takes a comprehensive look at the different types of in vivo assays and model organisms that has been utilized for the investigation of bioavailability, release profile and possible toxicity of food-based nanomaterials so far.

Abstract
Herein, we report a micro-plasma assisted solvothermal synthesis and characterization of zinc oxide nanosheets (ZnO-NSs) and their application for the removal of Cr6+ ion from aqueous solution. The morphological investigations by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) confirmed the high-density growth of nanosheets with the typical sizes in the range of 145.8–320.25 nm. The typical surface area of the synthesized ZnO-NSs, observed by Brunauer-Emmett-Teller (BET), was found to be 948 m2/g. The synthesized ZnO-NSs were used as efficient absorbent for the removal of Cr6+ ion from aqueous solution. Various parameters such as pH, contact time, amount of adsorbate and adsorbent on the removal efficiency of Cr6+ ion was optimized and presented in this paper. At optimized conditions, the highest value for removal was 87.1% at pH = 2 while the calculated maximum adsorption capacity was ~87.37 mg/g. The adsorption isotherm data were found to be best fitted to Temkin adsorption isotherm and the adsorption process followed the pseudo-first-order kinetics. Furthermore, the toxicity of ZnO-NSs were also examined against fibroblast cells, which show favorable results and proved that it can be used for wastewater treatment.

Abstract
Zinc Oxide nanoparticles (ZnO NPs) has been heavily used in the industry, and increasing concerns on the ecotoxicity has arisen due to the risk of release into the environment. In this work, silkworm was used here as a model organism to study the toxicity of ZnO NPs, due to the presence of a conserved immune response as well as a pharmacokinetics similar to mammals. Zn accumulation, biodistribution and toxicity in silkworms were monitored at different time points after a subcutaneous injection. The highest cumulative content of ZnO NPs was detected in the midgut. The results of catalytic activity studies confirmed that the antioxidant enzymes (SOD, CAT, GSH-PX) in midgut cells were expressed in response to ZnO NPs. The expression of genes (Dronc and Caspase-1) related to apoptosis was increased, while the Trt gene was down-regulated. A possible mechanism was proposed for toxicity of ZnO NPs to silkworms.

Abstract
This article presents a state-of-the-art review and analysis of literature studies on the morphological structure, fabrication, cytotoxicity, and photocatalytic toxicity of zinc oxide nanostructures (nZnO) of mammalian cells. nZnO with different morphologies, e.g., quantum dots, nanoparticles, nanorods, and nanotetrapods are toxic to a wide variety of mammalian cell lines due to in vitro cell-material interactions. Several mechanisms responsible for in vitro cytotoxicity have been proposed. These include the penetration of nZnO into the cytoplasm, generating reactive oxygen species (ROS) that degrade mitochondrial function, induce endoplasmic reticulum stress, and damage deoxyribonucleic acid (DNA), lipid, and protein molecules. Otherwise, nZnO dissolve extracellularly into zinc ions and the subsequent diffusion of ions into the cytoplasm can create ROS. Furthermore, internalization of nZnO and localization in acidic lysosomes result in their dissolution into zinc ions, producing ROS too in cytoplasm. These ROS-mediated responses induce caspase-dependent apoptosis via the activation of B-cell lymphoma 2 (Bcl2), Bcl2-associated X protein (Bax), CCAAT/enhancer-binding protein homologous protein (chop), and phosphoprotein p53 gene expressions. In vivo studies on a mouse model reveal the adverse impacts of nZnO on internal organs through different administration routes. The administration of ZnO nanoparticles into mice via intraperitoneal instillation and intravenous injection facilitates their accumulation in target organs, such as the liver, spleen, and lung. ZnO is a semiconductor with a large bandgap showing photocatalytic behavior under ultraviolet (UV) light irradiation. As such, photogenerated electron-hole pairs react with adsorbed oxygen and water molecules to produce ROS. So, the ROS-mediated selective killing for human tumor cells is beneficial for cancer treatment in photodynamic therapy. The photoinduced effects of noble metal doped nZnO for creating ROS under UV and visible light for killing cancer cells are also addressed.

Abstract
Small-cell lung cancer, a highly malignant form of lung cancer, often responds to first-line treatments but relapses in most cases with resistance to further treatments. We tested zinc oxide (ZnO) nanoparticles against small-cell lung cancer and other cancer cell lines, in light of reported anticancer effects in vitro Because of a strong safety record, ZnO nanoparticles are frequently used in biomedical research, including in cellular imaging and drug delivery, and have been used for many years in several commercial products such as skin care agents. Strikingly, ZnO nanoparticles were genotoxic against small-cell lung cancer cells, resulting in low viability, even in cells orthotopically grafted onto mouse models. However, the nanoparticles were less cytotoxic against normal lung-derived cells and did not elicit observable adverse effects after intravenous administration. ZnO nanoparticles were also found to induce highly reactive oxygen species and DNA leakage from nuclei. This study is the first comprehensive evaluation of the anticancer effects of ZnO nanoparticles in vitro and in vivo and highlights new therapeutic opportunities against small-cell lung cancer.

Abstract
The unique anticancer, biochemical, and immunologic properties of nanomaterials are becoming a new tool in biomedical research. Their translation into the clinic promises a new wave of targeted therapies. One nanomaterial of particular interest are zinc oxide (ZnO) nanoparticles (NPs), which has distinct mechanisms of anticancer activity including unique surface, induction of reactive oxygen species, lipid oxidation, pH, and also ionic gradients within cancer cells and the tumor microenvironment. It is recognized that ZnO NPs can serve as a direct enzyme inhibitor. Significantly, ZnO NPs inhibit extracellular signal-regulated kinase (ERK) and protein kinase B (AKT) associated with melanoma progression, drug resistance, and metastasis. Indeed, direct intratumoral injection of ZnO NPs or a complex of ZnO with RNA significantly suppresses ERK and AKT phosphorylation. These data suggest ZnO NPs and their complexes or conjugates with nucleic acid therapeutic or anticancer protein may represent a potential new strategy for the treatment of metastatic melanoma, and potentially other cancers. This review focuses on the anticancer mechanisms of ZnO NPs and what is currently known about its biochemical effects on melanoma, biologic activity, and pharmacokinetics in rodents and its potential for translation into large animal, spontaneously developing models of melanoma and other cancers, which represent models of comparative oncology.

Abstract
Successful development of safe and highly effective nanoprobes for targeted imaging of in vivo early cancer is a great challenge. Herein, we choose the visible-light emitting zinc oxide non-core/shell type nanoparticle (NP) fluorophores (ZHIE) as prototypical materials. We have reported on these materials previously. The results showed that the ZHIE NPs exhibited good water solubility and good biocompatibility. This study was conducted to investigate the toxicity of ZHIE NPs when intravenously administered to mice repeatedly at the dose required for successful tumor imaging in vivo. Anti-macrophage-1 antigen (Mac1), a macrophage differentiation antigen, antibody-conjugated ZHIE NPs successfully realized targeted imaging of murine macrophage cell line Raw264.7 cells. In conclusion, ZHIE NPs are not toxic in vivo and antibody-conjugated ZHIE NPs have great potential in applications, such as single cell labeling.

Abstract
Background Inhaled nanoparticles can deposit in the deep lung where they interact with pulmonary cells. Despite numerous studies on pulmonary nanotoxicity, detailed molecular mechanisms of specific nanomaterial-induced lung injury have yet to be identified. Results Using whole-body dynamic inhalation model, we studied the interactions between aluminum oxide nanoparticles (Al2O3 NPs) and the pulmonary system in vivo. We found that seven-day-exposure to Al2O3 NPs resulted in emphysema and small airway remodeling in murine lungs, accompanied by enhanced inflammation and apoptosis. Al2O3 NPs exposure led to suppression of PTPN6 and phosphorylation of STAT3, culminating in increased expression of the apoptotic marker PDCD4. Rescue of PTPN6 expression or application of a STAT3 inhibitor, effectively protected murine lungs from inflammation and apoptosis, as well as, in part, from the induction of chronic obstructive pulmonary disease (COPD)-like effects. Conclusion In summary, our studies show that inhibition of PTPN6 plays a critical role in Al2O3 NPs-induced COPD-like lesions.

Abstract
Because of the complexity of cancer, an ideal anticancer strategy is better to target both cancer cells and the tumor microenvironment. In this study, for the first time, we demonstrated that zinc oxide nanoparticles (ZnO NPs) were able to target multiple cell types of cancer, including cancer cells, cancer stem cells (CSCs), and macrophages, and simultaneously perform several key functions, including inhibition of cancer proliferation, sensitization of drug-resistant cancer, prevention of cancer recurrence and metastasis, and resuscitation of cancer immunosurveillance. As a nanocarrier, the chemotherapy drug, doxorubicin (Dox), could be loaded to ZnO NPs and the Dox-loaded ZnO NPs (ZnO/Dox) possessed excellent physicochemical and pH-responsive drug release properties. ZnO/Dox could be effectively internalized by both drug-sensitive and multidrug resistant (MDR) cancer cells and penetrate more efficiently through three-dimensional (3D) cancer cell spheroids compared with free Dox. As a cytotoxic agent, ZnO NPs were more efficient to kill MDR cancer cells. Interestingly, neither ZnO nor Dox showed high cytotoxicity in the 3D cancer cell spheroids, whereas ZnO/Dox showed remarkable synergistic anticancer effects. More importantly, we demonstrated that ZnO NPs could effectively downregulate CD44, a key CSC surface marker, and decrease the stemness of CSCs, leading to the sensitization of the Dox treatment, inhibition of the cancer cell adhesion and migration, and prevention of the tumor (3D cancer cell spheroid) formation. As an immunomodulator, ZnO NPs could protect macrophages from the Dox-induced toxicity and boost the Dox-induced macrophage polarization toward an M1-like phenotype. The macrophage-conditioned medium could promote the cancer cell apoptosis in both cancer cell monolayers and 3D spheroids. The findings in this study indicated that ZnO NPs were a multifunctional and multitarget nanocarrier and nanomedicine that would have more profound effects on cancer treatment.

Abstract
Zinc homeostasis in cells depends on zinc transporters, which are divided into 2 families: ZnT (SLC30A) and ZIP (SLC39A). In this study, we examined the effect of 20 single nucleotide polymorphisms (SNPs) in 10 genes encoding zinc transporters on blood zinc concentration in Japanese subjects (n = 102). Blood zinc levels were determined by microwave plasma-atomic emission spectrometry, and SNPs were analyzed by polymerase chain reaction followed by restriction fragment length polymorphism analysis. Among the 20 SNPs examined, 3 SNPs (SLC30A3 rs11126936, SLC39A8 rs233804, and SLC39A14 rs4872479) were significantly associated with blood zinc concentration. Individuals with genotype TT and TG in rs11126936 showed significantly higher blood zinc concentrations than those with GG. As for rs233804, individuals harboring the A allele had significantly higher blood zinc concentrations than those without this allele. Furthermore, the genotype TT and TG in rs4872479 had significantly higher blood zinc concentrations than those with GG. Among these three SNPs, combination of SLC30A3 rs11126936 and SLC39A8 rs233804 may strongly affect blood zinc levels. This study is the first comprehensive investigation of the effect of SNPs in genes encoding zinc transporters on blood zinc concentration. Adverse effects of zinc deficiency are reported and above 3 SNPs may be related to genetic susceptibility to zinc deficiency.

Abstract
Inhalation exposure to engineered nanomaterials (ENMs) may result in adverse pulmonary and/or systemic health effects. In this study, enhanced darkfield microscopy (EDFM) was used as a novel approach to visualizing industrial metal oxide nanoparticles (NPs) (silica, ceria, or alumina) in multiple tissue types following inhalation in rats mimicking occupational exposures. Advantages of EDFM over electron microscopy (EM) include reduced cost, time, and ease of sample preparation and operation. Following 4-6 hour inhalation exposures at three concentrations (3.5-34.0 mg/m3 ), lungs and secondary organs were harvested at 24 hours or 7 days post-exposure and prepared for brightfield (BF) microscopy and EDFM. NPs were visualized within the lung and associated lymphatic tissues and in major organs of excretion (liver, spleen, kidney). EDFM also revealed NPs within pulmonary blood vessels and localization within specific regions of toxicological relevance in liver and kidney, indicating pathways of excretion. Results demonstrate the utility of EDFM for rapid direct visualization of NPs in various tissue types and suggest the potential for metal oxide NPs to distribute to secondary tissues following inhalation exposure. Confirmation of the composition, distribution, and relative abundance of inhaled NPs will be pursued by combining EDFM with hyperspectral imaging (HSI) and mapping.

Abstract
Although it is expected that accumulation of metal oxide nanoparticles that can induce redox reaction in the biological system may influence ion homeostasis and immune regulation through generation of free radicals, the relationship is still unclear. In this study, mice received magnetic iron oxide nanoparticles (M-FeNPs, 2 and 4 mg/kg) a single via the tail vein, and their distribution in tissues was investigated over time (1, 4, and 13 weeks). In addition, we evaluated the effects on homeostasis of redox reaction-related elements, the ion environment and immune regulation. The iron level in tissues reached at the maximum on 4 weeks after injection and M-FeNPs the most distributed in the spleen at 13 weeks. Additionally, levels of redox reaction-related elements in tissues were notably altered since 1 week post-injection. While levels of K(+) and Na(+) in tissue tended to decrease with time, Ca(2+) levels reached to the maximum at 4 weeks post-injection. On 13 weeks post-injection, the increased percentages of neutrophils and eosinophils, the enhanced release of LDH, and the elevated secretion of IL-8 and IL-6 were clearly observed in the blood of M-FeNP-treated mice compared to the control. While expression of antigen presentation related-proteins and the maturation of dendritic cells were markedly inhibited following distribution of M-FeNPs, the expression of several chemokines, including CXCR2, CCR5, and CD123, was enhanced on the splenocytes of the treated groups. Taken together, we suggest that accumulation of M-FeNPs may induce adverse health effects by disturbing homeostasis of the immune regulation and ion environment.

Abstract
BACKGROUND Rod-shaped cadmium sulfide nanoparticles (CdS NPs) are becoming increasingly important in many industrial fields, but their potential hazards remain unknown. OBJECTIVES This study aimed to explore the patterns and mechanisms of lung injury induced by CdS NPs. METHODS A549 cells and rats were exposed to two types of CdS NPs with a same diameter of 20-30 nm but different lengths, CdS1 (80-100 nm) and CdS2 (110-130 nm). The using doses were included 10 μg/ml and 20 μg/ml two types of CdS NPs for cellular experiments and five times dose of 20 mg/kg body weight for rats' exposure. Methylthiazolyldiphenyl-tetrazolium bromide (MTT) and trypan blue staining were used to detect the A549 cell mortality percentage. The levels of reactive oxygen species (ROS) were determined in A549 cell. The vigor of superoxide dismutase (SOD) and the contents of catalase (CAT) and malondialdehyde (MDA) were detected both in A549 cells and in rats' serum and lung tissues. The cellular morphological changes were observed under transmission electron microscopy (TEM) and the pathological changes were observed in rats' lung tissue. RESULTS CdS NPs significantly increased A549 cell mortality percentage. The CdS NPs also increased the levels of ROS and MDA content, whereas they decreased SOD and CAT activities. In parallel, similar changes of the contents of MDA, SOD and CAT were also observed in the sera and lung tissues of CdS NP-treated rats. The cellular TEM detection revealed that two types of CdS nanorods appeared as orderly arranged rounded fat droplets separately and leading to nucleus condensation (CdS1). These cellular and rats' tissues changes in the group treated with CdS1 were more significant than the CdS2 groups. Furthermore, CdS NPs induced many pathological changes, including emphysematous changes in rat lung tissue. Especially visible lung consolidation can be observed in the CdS1 group. CONCLUSIONS CdS NPs induce oxidative injury in the respiratory system, and their toxic effects may be related to grain length.

Abstract
Background: Application of nanoenzymes, based on D-amino acid oxidase (DAAO) conjugated to magnetic nanoparticles (NPs), as anticancer system requires improvement of the synthesis protocol and in vivo distribution evaluation. Results: A new and more efficient synthesis via EDC-NHS produced an Fe3O4NP-APTES-DAAO system with a specific activity of 7 U/mg NPs. IR spectroscopy showed that all Fe3O4 NP sites are saturated with APTES and all available NH2 sites with DAAO. The acute cytotoxicity of the new system does not differ from that of the previous one. In vivo experiments showed that the system did not cause adverse effects, cross the brain–blood barrier and accumulate in the heart. Conclusions: Our results support the possibility to use enzymes conjugated to magnetic NPs for cancer treatment. Besides, we think that enzymes and other biological molecules efficiently conjugated to magnetic NPs might constitute a category of ‘bionanoparticles’ to be exploited, not only in medical, but also in industrial biotechnology. Lay abstract: We have linked magnetic nanoparticles to D-amino acid oxidase, an enzyme capable of producing, in the presence of its substrate, reactive oxygen species. The scope is to use the magnetic properties of the enzyme-nanoparticle system to direct it to a desired area where its cytotoxicity can be controlled by the addition of exogenous substrate. Besides the possible applications in cancer therapy, we think that enzymes and other biological molecules linked to magnetic nanoparticles might also be exploited in industrial biotechnology.
