MetabolomicsTitanium dioxide in food induces sex- and microbiota-dependent metabolic disorders, and worsens high-fat diet outcomes
Ultra-processed food consumption has been linked to the rising global burden of metabolic diseases, but the specific contribution of additives commonly used in these products remains unclear. Given the bactericidal properties of the food-grade (fg) additive titanium dioxide (TiO2) and the key role o...

TranscriptomicsMaternal inhalation of surface-coated nano-sized titanium dioxide (UV-Titan): Effects in prenatally exposed offspring on hepatic DNA damage and gene expression
In the present study we investigate the effect of maternal pulmonary exposure to titanium dioxide (UV-Titan designed for use in the paint and lacquer industry) on prenatally exposed offspring. Time-mated mice (C57BL/6BomTac) were exposed by inhalation for 1 h/day to 42 mg UV-titan/m3 aerosolized pow...

TranscriptomicsInvestigation of Alterations in Gene Expression in the Retina Induced by Intravitreal Injection of titanium dioxide nanoparticles
In this study, we investigated the safety of locally delivered titanium dioxide nanoaprticles at the level of gene expression in the retina. To figure out any definite dose-dependent effect, we injected titanium dioxide nanoparticles into the vitreous cavity of 8-week-old male C57BL/6 mice at the co...

TranscriptomicsTitanium dioxide nanoparticles exposure
This project utilized oligonucleotide microarrays to examine gene expression patterns in adult male fathead minnows (Pimephales promelas) exposed to a common nanomaterial, titanium dioxide (TiO2, stearate-coated particles, MT-100TV®). We exposed adult male fathead minnows for 96 hr to three doses (...

TranscriptomicsTranscription profiling of mouse inflammatory response to titanium dioxide particles exposure is enhanced during pregnancy
Rationale: Maternal immune responses can promote allergy development in offspring. Pilot data show that neonates of mother mice exposed during pregnancy to air pollution particles have increased allergic susceptibility. Objective: We investigated whether inflammatory response to titanium dioxide (Ti...

ProteomicsMolecular responses of alveolar epithelial A549 cells to chronic exposure to titanium dioxide nanoparticles: a proteomic view
Although the biological effects of titanium dioxide nanoparticles (TiO2-NPs) have been studied for more than two decades, the mechanisms governing their toxicity are still unclear. We applied 2D-gel proteomics analysis on A549 epithelial alveolar cells chronically exposed for 2 months to 2.5 or 50 µ...

TranscriptomicsEffect of Titanium dioxide nanoparticles on Escherichia coli K12 MG1655 genes expression
In the present study, we investigated the transcriptional expression patterns of the model strain E. coli exposed to titanium dioxide nanoparticles (NP-TiO2), under dark conditions by using a microarray. Expression profiles were compared to unexposed E.coli and ratio of expression were analysed. Cel...
