Gene Expression Analysis of the Short Term Ingestion of Titanium Dioxide Nanofibers


ABSTRACT: Titanium dioxide nanofiber (TDNF) is widely used in the manufacture of various household products including cosmetics. As a result, there is a possibility of negative impact on human health. The goal of the present study is to investigate the short-term effects of titanium dioxide nanofiber ingestion of male Sprague Dawley rats. TDNF was fabricated via electrospinning method, followed by dissolution in water. Six- to seven-week-old male Sprague Dawley rats were exposed to a total of 0, 40, and 60 ppm of TDNF for 2 weeks via oral gavage. Lungs and other tissues were autopsied and excised immediately frozen in liquid nitrogen and stored at -80 deg C until analysis. Total RNA was converted to single-stranded sense-target, fragmented, labeled, and hybridized to the Affymetrix Rat Gene ST 2.0 microarray according to the manufacturer’s protocol.
