<h4>Background</h4>Understanding of iron oxide nanoparticles (IONP) interaction with the body milieu is crucial to guarantee their efficiency and biocompatibility in nanomedicine. Polymer coating to IONP, with polyethyleneglycol (PEG) and polyvinylpyrrolidone (PVP), is an accepted strategy to prevent toxicity and excessive protein binding.<h4>Aim</h4>The aim of this study was to investigate the feature of IONP adsorption of complement proteins, their activation and consequent inflammatory respon ...[more]

Plasma protein corona on superparamagnetic iron oxide nanoparticles (SPIONs)

Project description:We determined the composition of the plasma protein corona on silica-coated versus dextran-coated iron oxide nanoparticles using mass spectrometry-based proteomics approaches. Gene ontology (GO) enrichment analysis and Ingenuity Pathway Analysis (IPA) revealed distinct protein corona compositions for the two different SPIONs. Relaxivity of silica-coated SPIONs was modulated by the presence of a protein corona. Moreover, the viability of primary human monocyte-derived macrophages was influenced by the protein corona on silica-coated, but not dextran-coated SPIONs, and the protein corona promoted cellular uptake of silica-coated SPIONs, but did not affect internalization of dextran-coated SPIONs.

Quantitative proteomic analysis of iron oxide nanoparticles toxicity in rats

Project description:Iron oxide nanoparticles (IONPs) are the first generation of nanomaterials approved by the Food and Drug Administration for use as imaging agents and for the treatment of iron deficiency in chronic kidney disease. However, several IONPs-based imaging agents have been withdrawn because of toxic effects and the poor understanding of the underlying mechanisms. This study aimed to evaluate IONPs toxicity via proteomics and to elucidate the underlying mechanism after intravenous administration in rats.

Iron oxide nanoparticles inhibit tumor progression and suppress lung metastases in mouse models of breast cancer [RNA-seq]

Project description:Systemic exposure to starch-coated iron oxide nanoparticles (IONPs) can stimulate antitumor T cell responses, even when little IONP is retained within the tumor. Here, we demonstrate in mouse models of metastatic breast cancer that IONPs can alter the host immune landscape leading to systemic immune-mediated disease suppression. We report that a single intravenous injection of IONPs can inhibit primary tumor growth, suppress metastases, and extend survival. Gene expression analysis revealed activation of Toll-like receptor (TLR) pathways involving signaling via Toll/Interleukin-1 Receptor domain-containing adaptor-inducing IFN-β (TRIF), a TLR pathway adaptor protein. Requisite participation of TRIF in suppressing tumor progression was demonstrated with histopathologic evidence of upregulated IFN-regulatory factor 3 (IRF3), a downstream protein, and confirmed in a TRIF knockout syngeneic mouse model of metastatic breast cancer. Neither starch-coated polystyrene nanoparticles lacking iron, nor iron-containing dextran-coated parenteral iron replacement agent induced significant antitumor effects suggesting a dependence on the type of IONP formulation. Analysis of multiple independent clinical databases support a hypothesis that upregulation of TLR3 and IRF3 correlates with increased overall survival among breast cancer patients. Taken together, these data support a compelling rationale to re-examine IONP formulations as harboring anti-cancer immune (nano)adjuvant properties to generate therapeutic benefit without requiring uptake by cancer cells.

Effects of seed priming mediated by iron oxide magnetic nanoparticles (MNPs) in Capsicum annuum

Project description:Nanotechnology has the potential to revolutionize agriculture by developing engineered nanomaterials to be used as biostimulants, fertilizers, pesticides or smart sensors. Seed priming may represent an opportunity for nano-enabled plant technology to match economic, agronomic and environmental needs. This study investigates the effects of seed priming mediated by iron oxide magnetic nanoparticles (MNPs) in plants. We performed a multilevel integrated study to understand the basic interactions between MNPs and seeds in pepper (Capsicum annuum). Moreover, phenotypic, physiological and molecular analyses were performed to elucidate the biological impact of MNPs from seed to plant development. Interestingly, our findings show positive effects of MNPs on vegetative growth and a profound impact on pepper gene expression patterns. Indeed, we found 2,204 differentially expressed transcripts in nanoprimed seeds, most of them involved in plant defence mechanisms, potentially establishing a seed memory that might enhance the plant's capacity to counteract diverse forms of stress. In conclusion, this work provides a comprehensive investigation about nanoparticle-seed interactions with interesting implications for agricultural technology.

Molecular mechanism of Arabidopsis thaliana seedlings in response to phytotoxicity of yttrium oxide nanoparticles

Project description:Due to the wide application of rare earth oxides nanoparticles in different fields, they will inevitably be released into the environment, and their potential toxicity and ecological risks in the environment have become a concern of people. Yttrium oxide nanoparticles are important members of rare earth oxides nanoparticles. The molecular mechanism of its influence on plant growth and development and plant response to them is unclear. In this study, we found that yttrium oxide nanoparticles above 2 mM significantly inhibited the growth of Arabidopsis seedlings. Using the Arabidopsis marker lines reflecting auxin signal, it was found that the treatment of yttrium oxide nanoparticles led to the disorder of auxin signal in root cells: the auxin signal in quiescent center cells and columella stem cells decreased; while the auxin signal in the stele cells was enhanced. In addition, trypan blue staining showed that yttrium oxide nanoparticles caused the death of root cells. Transcriptome sequencing analysis showed that yttrium oxide nanoparticles specifically inhibited the expression of lignin synthesis related genes, activated mitogen-activated protein kinase (MAPK) signaling pathway, and enhanced ethylene and ABA signaling pathways in plants. This study revealed the phytotoxicity of yttrium oxide nanoparticles at the molecular level, and provided a new perspective at the molecular level for plants to respond to rare earth oxide stress.

Super-paramagnetic iron oxide nanoparticles reprogram the tumor microenvironment and reduce lung cancer growth

Project description:Tumor associated macrophages (TAMs) are known to play a role in a multitude of processes that facilitate lung cancer growth, including the suppression of tumoricidal immune activation and the absorption of chemotherapeutics. Therefore, deciphering new therapies to reprogram TAMs towards an anti-tumor phenotype is at the cutting-edge of therapy development. The presence of iron-loaded macrophages has been associated with a better prognosis in lung cancer patients. Iron accumulation in macrophages stimulates pro-tumoricidal macrophage activity that triggers cytotoxic T-cell responses in the tumor microenvironment. In this study, we propose super-paramagnetic iron oxide nanoparticles (SPIONs) as a promising anti-lung cancer adjuvant therapy to reduce tumor cell growth. We used SPIONs to target iron to macrophages and observed that SPION-loaded macrophages reduced tumor cell growth due to the oxidative stress. Additionally, we found that SPIONs completely rewire the tumor microenvironment in mice towards an anti-tumor state and that in combination with crizotinib, a lung cancer targeted therapy, SPIONs show an additive effect in decelerating tumor growth

Transcriptomic fingerprints of C. elegans exposed to citrate coated superparamagnetic iron oxide nanoparticles (C-SPIONs)

Project description:Superparamagnetic Iron Oxide Nanoparticles (SPIONs) are currently being investigated for a range of biomedical applications. Their use have been related with different cytotoxic mechanisms including the generation of oxidative stress and the induction of metal detoxification pathways, among others. We have investigated the molecular mechanisms responsive to in-house fabricated citrate coated SPIONs (C-SPIONs) in the nematode C. elegans to compare in vivo findings with previous in vitro studies. C-SPIONs (500 µg/ml) affected the transcriptional response of signal transduction cascades (i.e. TFG-beta), protein processing in the endoplasmic reticulum, and RNA transport, among other biological processes. They also triggered a lysosomal response, indicating a relevant biological role of this cellular compartment in the response to this nanoparticle treatment in C. elegans. Interestingly, other pathways frequently linked to nanotoxicity like oxidative stress or apoptosis were not identified as significantly affected in this genome-wide in vivo study despite the high dose of exposure.
