Fig. 1From: Differences in TGF-β1 signaling and clinicopathologic characteristics of histologic subtypes of gastric cancerImmunohistochemical staining of TGF-β1 signaling molecules. TGFβR2, TGF receptor II; TAK1, TGF associated kinase 1; i-GC, intestinal type gastric cancer; d-GC, diffuse type gastric cancer. All cases were positively stained with each TGF-β1 signaling molecules. TGF-β1, TβR2 and TAK1 were stained in cell membrane and cytoplasm, while Smad4, p-Erk1/2 and p-Akt were stained in nucleusBack to article page
