* Genome wide identification and expression profile in epithelial cells exposed to TiO₂ particles.

- Environmental particles are believed to provoke airway inflammation in susceptible individuals by stimulating epithelial cells to release mediators that exacerbate lung diseases. Here, we sought to identify genes expressed throughout the genome by epithelial cells stimulated with TiO2 particles. A human bronchial epithelial cell line, BEAS-2B, was stimulated with or without 40 µg TiO2 for 2 h. RNA was purified from cells and subjected to microarray analysis. Genes exhibiting more than a twofold change in RNA expression were selected. Candidate genes were then analyzed using bioinformatics tools, including pathway, ontology, and network analyses. ITGAV mRNA expression levels were measured in BEAS-2B cells using real-time polymerase chain reaction. Among 37,803 genes, 92 genes displayed more than a twofold change in mRNA levels according to the microarray analysis; 87 genes were upregulated while five genes were downregulated. The 92 genes were classified based on functional annotation using a protein information resource database search for biological processes and a pathway search using the KEGG pathway database. These genes are related to macromolecule biosynthesis, metabolic processes and, in particular, RNA metabolism. When genes with more than a threefold change were analyzed, KIF11, ITGAV, SEMA3C, IBTK, and DEK were selected as candidate genes induced by TiO2 -stimulated BEAS-2B cells. To validate these results, BEAS-2B cells stimulated with 40 µg TiO2 expressed threefold higher ITGAV mRNA levels compared to those without TiO2 particle stimulation. We conclude that KIF11, ITGAV, SEMA3C, IBTK, and DEK are candidate genes expressed by epithelial cells when stimulated with TiO2 particles.
