Smad7 was overexpressed in HCC tissue. a Representative IHC images showing the upregulation of Smad7 in HCC tissue (up) and the normal expression of Smad7 in HCC adjacent non-tumor tissue (down). (Scale bars = 30 μm). b The expression of mRNA level of Smad7 was detected in 50 HCC patients by RT-qPCR. **p < 0.01. c The Smad7 protein expression levels in HCC tissues and paired non-tumor tissues were examined using western blotting. *p < 0.05; **p < 0.01
