Fig. 2: Cytosolic localization of TFF3.

a TFF3 expression and subcellular localization in PCa cell lines (LNCap and PC-3) and a normal prostate cell line (WPMY-1) identified by immunocytochemistry. TFF3 (green fluorescence); Nucleus (Hoechst 33342, blue). b The cytosolic expression of TFF3 was confirmed by western blot analysis of subcellular fractions in LNCap and PC-3 cells
