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

ABSTRACT: 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.

Improved Biocompatibility of Amino-functionalized Graphene Oxide in Caenorhabditis elegans

Project description:Graphene oxide (GO) holds high promise for diagnostic and therapeutic applications in nanomedicine but reportedly displays immunotoxicity, underlining the need for developing functionalized GO with improved biocompatibility. Here, we study the adverse effects of GO and amino-functionalized GO (GONH2) during Caenorhabditis elegans development and ageing upon acute or chronic exposure. Chronic GO treatment throughout the C. elegans development causes decreased fecundity and a reduction of animal size, while acute treatment does not lead to any measurable physiological decline. However, RNA-Seq data reveal that acute GO exposure induces innate immune gene expression. The p38 MAP kinase, PMK-1, which is a well-established master regulator of innate immunity, protects C. elegans from chronic GO toxicity, as pmk-1 mutants show reduced tissue-functionality and facultative vivipary. In a direct comparison, GONH2 exposure does not cause detrimental effects in the wild type or in pmk-1 mutants, and the innate immune response is considerably less pronounced. Our work establishes the enhanced biocompatibility of amino-functionalized GO in a whole-organism, emphasizing its potential as biomedical nanomaterial.

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.
