Investigation of Alterations in Gene Expression in the Retina Induced by Intravitreal Injection of titanium dioxide nanoparticles

ABSTRACT: 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 concentration of presumptive therapeutic concentration (PTC; 130.47 ng/ml) and 10 times PTC (1.30 μg/ml). We intravitreally injected PBS or titanium dioxide nanoparticles into the right eyes of 8-week-old male C57BL/6 mice (n = 12 per group). PBS-treated mice were regarded as negative control. Four retinal tissues were pooled into 1 test tube and prepared for further analyses.
