Figure 2

Effects of curcumin on Smad3 in IEC-6 cells with EMT induced by TGF-β1. IEC-6 cells were incubated with curcumin at the indicated doses for 24 hours followed by treatment with TGF-β1 for 7 days. (a) Western blotting analysis for Smad2/3 and p-Smad3 expression. (b) The ratio of grey values of p-Smad3/GAPDH bands, , , difference versus TGF-β1 group. (c) Immunofluorescence staining for nuclear translocation of pSmad3. Green indicates p-Smad3.
