Project description:To evaluate the biological effects at the transcriptional level of manufactured nanomaterials, we performed whole genome microarrays of rat alveolar macrophages (NR8383) exposed to multi-walled carbon nanotubes (MWCNTs) with different physicochemical properties.
Project description:To evaluate the biological effects at the transcriptional level of manufactured nanomaterials, whole genome microarray analysis of rat lungs intratracheally instilled with cellulose nanofibrils (CNFs) with different physicochemical properties or multi-walled carbon nanotubes (MWCNTs) were performed.
Project description:To evaluate the biological effects at the transcriptional level of manufactured nanomaterials, whole genome microarrays of rat alveolar macrophages (NR8383) exposed to three types of submicron-diameter carbon fibers (SCFs) with different physicochemical properties were performed. In comparison with the fibers of SCF1, the fibers of SCF2 were shorter, and the fibers of SCF3 were thinner.
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 impurity-free single-wall carbon nanotubes (SWCNTs).
Project description:To evaluate the transcriptional-level biological effects of manufactured nanomaterials, a whole-genome microarray analysis was performed on the lungs of a murine chronic obstructive pulmonary disease (COPD) model. Mice were intratracheally instilled with cellulose nanofibrils (CNFs) or multi-walled carbon nanotubes (MWCNTs).
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 single-wall carbon nanotubes (SWCNTs). Two kinds of the impurity-free singlewall carbon nanotubes (SWCNTs), CNT-1 or CNT-2 induced gene expression in rat alveolar macrophages were measured at 24 hours exposure to doses of 0.1mg/mL. The experiments were performed using control for each experiment (n=4).
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), namely, relatively small bundles and a short linear shape (CNT-1) and large bundles and a long linear shape (CNT-2).
Project description:In this study we exposed three human lung derived cell lines to sublethal dosages of nanomaterials for a limited amount of time. For the first time, we assessed the simultaneous effects of nanomaterials exposure on three distinct molecular layers along with their interactions in the determination of the MOA of 10 carbon based nanomaterials. By performing an integrative analysis we provide here a complete picture of the interaction between regulatory factors (DNA methylation and miRNAs) and mRNA deregulation subsequent to exposing different cellular systems to different nanomaterials.
