Fig. 5From: Effects of differently shaped TiO2NPs (nanospheres, nanorods and nanowires) on the in vitro model (Caco-2/HT29) of the intestinal barrierGene expression of Caco-2/HT29 molecular markers in response to 24 or 48 h of TiO2NPs-S, TiO2NPs-R, and TiO2NPs-W exposure. Results represented as mean ± SEM. Bars that do not share any letter are significantly different according to the one-way ANOVA with Tukey’s post-test (P < 0.05)Back to article page
