Figure 4.
ZO-1, Claudin-1 and Occludin mRNA levels in Caco-2 monolayers after 6 h of exposure to gliadin (1 mg/ml) alone or in combination with viable L.GG (108 CFU/ml), in presence or absence of polyamines following administration of α-Difluoromethylornithine (DFMO). All data represent the results of three different experiments (mean ± SEM). A. ZO-1 mRNA levels; B. Claudin-1 mRNA levels; C. Occludin mRNA levels. Data were analyzed by Kruskal-Wallis analysis of variance and Dunn’s Multiple Comparison Test. (*) P < 0.05 compared to gliadin treated cells.
