Figure 5.

Western blot (upper) and densitometric analysis (down) of DMT1, ferritin light chain and ferroportin expressed on GTL-16 and Caco-2 cells treated with different iron formulations at 3 h and 24 h. The images are an example of four independent experiments for each cell type. The results obtained after normalization through β-act and then through control values are expressed as means ± SD of four independent experiments for each cell types. * p < 0.05 vs. control; ** p < 0.05 vs. correspondent column at different times; bars p < 0.05 among different treatments at the same time.
