Proteomics identification of total cellular proteins after five types of nanocarbon incubations with macrophages

ABSTRACT: Single-walled-carbon-nanohorns (SNH) exhibit huge application prospects. Notably, spherical SNH possess different morphology from conventional carbon nanotubes (CNT). However, there is a tremendous lack of studies on the nanotoxicity and mechanism of SNH, and their comparison with nanotubes. Here, the dissimilarity between SNH and CNT is found in nano-protein interaction. To validate the potential protein-mediated membrane disturbance caused by different nanocarbons, LC-MS/MS based on LFQ proteomics technology is utilized to compare the differences of total cellular proteins after different nanocarbon incubations and evaluate the impact of nanocarbons on protein expressions.

Improved biocompatibility of single-walled-carbon-nanohorns over nanotubes by triggering less protein-initiated pyroptosis and apoptosis in macrophages (proteomics identification of total cellular proteins based on identical intracellular nanocarbons)

Gene expression profiles in human alveolar epithelial cell line exposure to single carbon nanotubes

Project description:To further development of our gene expression approach to assess the effects of manufactured nanomaterials at the molecular level, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish characterization of physico-chemical properties of single-wall carbon nanotubes (SWCNTs). Three kinds of single-wall carbon nanotubes (SWCNTs), CNT-1, CNT-2 or CNT-3 induced gene expression in human alveolar epithelial cell lines were measured at 24 and 48 hours exposure to doses of 90.8Î¼g/mL (CNT-1), 109.0Î¼g/mL (CNT-2), and 77.0Î¼g/mL (CNT-2). Three independent experiments were performed at each time (24 or 48 hours) using different untreated control for each experiment (n=4).

Whole Blood long non-coding RNA and mRNA Expression Profiles in Humans Exposed to Multi-walled Carbon Nanotubes

Project description:As the application of carbon nanotubes (CNT) in consumer products continues to rise, studies have expanded to determine the associated risks of exposure on human and environmental health. In particular, several lines of evidence indicate that exposure to multi-walled carbon nanotubes (MWCNT) could pose a carcinogenic risk similar to asbestos fibers. However, to date the potential markers of MWCNT exposure are not yet explored in humans. Global mRNA and lncRNA expression profiles in the whole blood of exposed workers, having direct contact with MWCNT aerosols for atleast 6 months (n=8), were compared with expression profiles of non-exposed (n=7) workers (e.g., proffessional and/or technical staff) from the same manufacturing facility.

Gene expression profiles in rat lung following intratracheal instillation with impurity-free single-wall carbon nanotubes

Project description:To further development of our gene expression approach to assess the effects of manufactured nanomaterials at the transcriptional level, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish characterization of physicochemical properties of impurity-free single-wall carbon nanotubes (SWCNTs). We have prepared two types of dispersed the SWCNTs, namely relatively small bundles and a short linear shape (CNT-1) and large bundles and a long linear shape (CNT-2), and attempted to characterize time-dependent changes in the gene expression of lung tissues until 90 days after intratracheal instillation with SWCNTs suspensions at 0.4 mg injected dose per rat. Groups of nine-week-old male Wistar rats (n= 4 per group/ time point) were intratracheally instilled with single-wall carbon nanotubes (SWCNTs) suspended in 0.4 ml of 1.0mg/mL bovine serum albumin (BSA) as a single injection 0.4 mg SWCNTs/ rat. Control groups received 1.0mg/mL BSA (vehicle control). After intratracheal instillation treatment, rats were housed within polycarbonate cages at a controlled temperature of 22 M-BM-0C with a chow diet ad libitum, and dissected at 1day, 3 days, 7 days, 30 days, and 90 days post-instillation. Right lungs of anesthetized rats were perfused with physiological saline, excised, and used for DNA microarray analysis.

Gene expression in spinal cord neurons grown on polyornithine or on carbon nanotube (CNT)-based substrates

Project description:Carbon nanotubes are cylindrically-shaped carbon nanostructures, made up of layers of graphene rolled onto themselves, with diameters similar to those of neuronal processes. In the last decade, CNT have been used as biocompatible growing substrates for neuronal attachment, differentiation and growth. In the perspective of new developments in tissue engineering, and in particular in spinal cord repair strategies, based on the use of CNTs, our aim is to clarify the biophysical interactions between CNTs and spinal cord neurons, studying the development of the morphological and functional characteristics of spinal neurons grown on CNT-based interfaces. In this context, we used microarrays to show whether cultured dissociated spinal neurons show a difference in gene expression when grown in control conditions (polyornithine-covered substrates) or on CNT-based substrates. Gene expression profiling was evaluated from 3 replicates each of neurons grown on nanotubes and control conditions.

Effects of Carbon Nanotubes Substrates on dendritic cells

Project description:To assess the effect of carbon nanotubes substrated on dendritic cell (DCs) properties, DCs were generated from human monocytes of healthy donors as previously described (Aldinucci A et al, 2010). In particular, isolated monocytes were cultured for 6 days in medium supplemented with GM-CSF (1000U/ml) and IL-4 (1000U/ml), in presence or absence of multi-walled carbon nanotubes (MWCNT); then DCs were activated by 24 hours of incubation with LPS (1ug/ml). RNA extracted from floating and CNT adherent DCs were then used for transcriptional profilingthen used

RNA-seq of combinatory treatment of gemcitabine+UVI5008 and gemcitabine+MS275 in human pancreatic adenocarcinoma human cell lines

Project description:Epigenetic modifications could drive some of the molecular events implicated in proliferation, drug resistance and metastasis of pancreatic ductal adenocarcinoma (PDAC). Thus, epigenetic enzyme inhibitors could be the key to revert those events and transform PDAC into a drug-sensitive tumor.We have performed a systematic study with two different epigenetic enzyme inhibitors (UVI5008, MS275) targeting either Histone Deacetylase 17 (HDAC) 1 or 1/4, DNA methyltransferase 3a (DNMT3a), Euchromatic histone lysine methyltrans- 18 ferase 2 (EHMT2) or Sirtuin 1 (SIRT1), and one drug that restores the p53 function (P53R3), in three 19 different human PDAC cell lines (MIA PaCa-2 and BxPC-3). The synergistic effect of these antitumoral drugs with gemcitabine was tested and the most efficient combinations were characterized by RNA-seq. The combination of UVI5008 or MS275 with gemcitabine induced a synergistic effect at low concentration and the RNA-Seq analysis revealed some synergy candidate genes as potential biomarkers.
