Methylation arrays (MethylationEPIC) of human lung epithelial BEAS-2B cells exposed to reduced graphene oxide

Project description:Nanomaterials have lots of promising applications, and concern has risen about their impact to human health. Here, we have analyzed the genome-wide DNA methylation changes associated to the exposure to reduced graphene oxide (rGO) in human lung epithelial cells. Six conditions were assayed, with two technical replicates per condition (12 arrays in total): control, 1 and 10 µg/mL of rGO for 15 or 30 days of exposure.

A transcriptomic overview of lung and liver changes one day after pulmonary exposure to graphene and graphene oxide

Project description:This study investigates transcriptomic differences in the lung and liver after pulmonary exposure to two Graphene based materials with similar physical properties, but different surface chemistry. Female C57BL/6 mouse were exposed by a single intratracheal instillation of 0, 18, 54 or 162 μg/mouse of graphene oxide (GO) or reduced graphene oxide (rGO). Pulmonary and hepatic transcriptional changes were compared to identify commonly and uniquely perturbed functions and pathways by GO and rGO. These changes were then related to previously analyzed endpoints. GO exposure induced more differentially expressed genes, affected more functions, and perturbed more pathways compared to rGO, both in the lung and liver.

mRNA microarray analysis on HepG2 cells exposed to Grpahene oxide (GO) and reduced graphene oxide (rGO) Nanomaterials

Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to GO and rGO on Human hepatoma (HepG2) cells. We performed whole genome DNA microarray experiments using HepG2 cells exposed to GO and rGO for 24h. We used whole genome microarrays to screen for global changed in HepG2 transcription profiles and with subsequent quantitative analysis conducted on selected genes. 24h GO and rGO exposed HepG2 cells were used for total RNA extraction and hybridization on Affymetrix microarrays.

Single-cell mass cytometry reveals the impact of graphene nanomaterials with human primary immune cells

Project description:The genome-wide transcriptome analysis highlight the increased biocompatibility on immune cells of graphene functionalized with amino groups (NH2) compared with graphene oxide (GO); reducing the cell metabolism disfunction. Moreover, GONH2 was found to polarizes T-cell and monocyte activation toward a T helper-1/M1 immune response.

Graphene-polymer nanofibers enable optically induced electrical maturation in stem cell-derived cardiomyocytes and brain organoids

Project description:Pluripotent stem cell (PSC)-derived electrically excitable cells provide a unique window into human disease and development, but they remain electrically immature compared to their in vivo counterparts, partially due to the lack of chronic stimulation. New classes of on-demand, electrically active biomaterials are being employed to enhance cell functions, and here, we fabricated biocompatible, electrospun polymer nanofibers containing light-reactive reduced graphene oxide (rGO). Fiber size, stiffness, and electrical conductivity scaled with rGO concentration which in turn produced conduction-dependent effects in PSC-derived cardiomyocytes and neurons; with acute light stimulation on scaffolds containing rGO, cardiomyocytes exhibited more calcium handling activity and were more synchronous, and neurons showed more peaks with higher frequency. Chronic repetitive, daily light stimulation of nanofibers integrated into mature brain organoids caused organoids to become increasingly more electrically responsive to stimulation over time, mature synapses of excitable neurons, and activate photoreceptor lineage pathways. This work outlines a tunable method where the electrical function of electrically excitable, PSC-derived cells can be titrated with rGO fibers and light stimulation, and it suggests that repetitive light stimulation may provide a novel method for retinal cell differentiation in organoids.

Carbon nanotubes, but not graphene oxide, trigger chemokine production in primary human macrophages via MyD88 dependent NF-kB Pathway

Project description:The growing medical application of engineered nanomaterials (ENMs) necessitates better understanding of their molecular toxicity mechanisms governing immune effects. In the present study, a comprehensive mechanistic in vitro assessment of two carbon-based ENMs, single-walled carbon nanotubes (SWCNTs) and graphene oxide (GO), was performed using primary human monocyte-derived macrophages (HMDM) as a model. HMDM were exposed to SWCNTs and GO at concentrations 10–100 µg/ml for 24 h. Toxicity, reactive oxygen species (ROS) production and uptake of ENM by cells was measured. The changes in gene expression profile of HMDM in response to SWCNTs and GO were studied and the key stress response pathways identified. The transcriptomics and pathway enrichment analysis findings were verified by multiplex immunoassay and functional assays.
