TiO2-induced gene expression profiles in rat lung: a subacute inhalation study.

ABSTRACT: In this work we study the pulmonary toxicological properties of titanium dioxide using conventional and molecular toxicological approaches. For this, we exposed Fischer 344 rats by nose-only inhalation 6 hours/day, 5 days/week for 4 weeks to a nanoaerosol of TiO2 (10 mg/m3). Lung samples have been collected up to 180 days after the end of exposure. Biochemical and cytological analyses of the broncho-alveolar lavage fluid (BALF) were performed. In addition, transcriptomic and proteomic approaches were realised in the lung and BALF respectively.

An Adaptive Response through N6-Methyladenosine in Fetal Offspring following Gestational Nano-TiO2 Inhalation Exposure II

Project description:Background: N6-methyladenosine (m6A) is the most prominent epitranscriptomic modification to RNA in eukaryotes, but it’s role in adaptive changes within the gestational environment are poorly understood. Nano titanium dioxide (TiO2) exposure is common during pregnancy, though the impact fetal progeny is not entirely understood. We propose that gestational exposure to nano-TiO2 contributes to cardiac m6A methylation in fetal offspring and indirectly contributes to mitochondrial dysfunction.

Mechanisms of (photo)toxicity of TiO2 nanomaterials (NM103, NM104, NM105): using high-throughput gene expression in Enchytraeus crypticus

Project description:Titanium dioxide (TiO2) based nanomaterials (NMs) are among the most produced NMs worldwide. When irradiated with light, particularly UV, TiO2 is photoactive, a property that is explored for several purposes. There is an increasingly number of reports on the negative effects of photoactivated TiO2 to non-target organisms. We have here studied the effect of a suite of reference type TiO2 NMs i.e. NM103, NM104, NM105 and compared these to the Bulk) with and without UV radiation to the oligochaete Enchytraeus crypticus. High-throughput gene expression was used to assess the molecular mechanisms, while also anchoring it to known effects at organism level (i.e., reproduction). Results showed that the photoactivity of TiO2 (UV exposed) played a major role in enhancing TiO2 toxicity, activating transcription of oxidative stress, lysosome damage and apoptosis mechanisms. For non-UV activated TiO2, where toxicity at organism level (reproduction) was lower, results showed the potential for long-term effects (i.e., mutagenic and epigenetic). NM specific mechanisms were identified: NM103 affected transcription and translation, NM104_UV negatively affected reproductive system/organs; and NM105_UV activated superoxide anion response. Results provided mechanistic information for UV-related phototoxicity of TiO2 materials and evidences of the potential long-term effects.

Toxicogenomic effects of nano- and bulk TiO2 particles in the soil nematode Carnorhabditis elegans

Project description:The toxicity and toxicogenomics of selected anatase and rutile nanoparticles (NP) and bulk titanium dioxide (TiO2) particles were evaluated in the soil nematode Caenorhabditis elegans. Results indicated that bulk or nano-TiO2 particles were slightly toxic to soil nematode C. elegans, as measured by reproduction EC50 values ranging from 4 to 32 mg/L. Whole-genome microarray results indicated that the regulation of glutathione-S-transferase gst-3, cytochrome P450 cypp33-c11, stress resistance regulator scl-1, oxidoreductase wah-1, and embryonic development pod-2 genes were significantly affected by nano-sized and bulk TiO2 particles. More specifically, it was determined that anatase particles exerted a greater effect on metabolic pathways, whereas rutile particles had a greater effect on developmental processes. The up-regulation of the pod-2 gene corroborated the phenotypic effect observed in the reproduction test. Our results demonstrated that C. elegans is a good genomic model for nano-TiO2 toxicity assessment.

Differential Effects of TiO2 Nanotubes on Vascular Cells

Project description:The response of primary human endothelial (ECs) and vascular smooth muscle cells (VSMCs) to TiO2 nanotube arrays is studied through gene expression analysis. Microarrays revealed that nanotubes enhanced EC proliferation and motility, decreased VSMC proliferation, and decreased expression of molecules involved in inflammation and coagulation in both cell types. Network generated from significantly affected genes suggests that cells may be sensing nanotopographical cues via pathways previously implicated in sensing shear stress. DNA microarrays were used to analyze the response of primary human endothelial (ECs) and vascular smooth muscle cells (VSMCs) to nanotopographical TiO2 surfaces. The experiment incorporated a 1 color design and used Agilent arrays that contained roughly 44,00 60mer probes that provide complete coverage of the human genome. 19 arrays were hybridized and represent 4 biological replicates for each group ( with the exception of group VSMC-NT30, which has 3 biological replicates). Data was analyzed separately for each cell type ( EC or VSMC). Gene expression comparisons were made between control cells grown on flat titanium (Ti) and cells grown on either 30nm nanotubes (NT30) or 100nm nantubes ( NT-100).

mRNA microarray analysis on young adults C.elegans exposed to UV, TiO2 and UV+TiO2

Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to UV, TiO2 and UV+TiO2 on nematode, Caenorhabditis elegans. We performed whole genome DNA microarray experiments using age synchronized young adult C. elegans population exposed to UV, TiO2 and UV+TiO2 for 24h. We used whole genome microarrays to screen for global changed in C. elegans transcription profiles and with subsequent quantitative analysis conducted on selected genes.

Gene expression of lung macrophages in mice instilled with Silica, TiO2 or Saline

Project description:Mice were intranasally instilled at 6 weeks of age with silica, titanium dioxide, or saline control and macrophages were harvested by broncho-alveolar lavage at 14 weeks of age. RNA was isolated using RNeasy Mini kits (Qiagen). Due to low yield of RNA, mRNA was amplifed by RiboAmp kits (Arcturus) and resulting aRNA was indirectly labeled with Alexa-Fluor 647 dye (Molecular Probes). This was hybridized against Universal Mouse Reference RNA (Stratagene) which was indirectly labeled with Alexa-Fluor 555 dye (Molecular Probes). Slides were printed in house using PCR product cDNA targets on GAPS slides (Corning). Slides were scanned with an Axon GenePix 4000B scanner and data was analyzed using GenePix Pro 4.0 software and Iobion GeneTraffic Duo software. Data was normalized to a total 1:1 ratio of read to green dye.
