<p>(A) Western blot analysis of NS protein expression in HCC cells and the hepatic non-tumor cell line L02. (B) Quantification of NS protein levels in various HCC cell lines and L02 cells. Image J method was performed to quantificate the western blots (n = 3), and GAPDH is a loading control. *P<0.05, **P<0.01. (C) Expression of NS mRNA in 18 matched samples of liver tumor and para-cancerous tissues. (D) Representative western blot of NS in HCC and para-cancerous tissues. N, para-cancerous tissue; T, tumor. (E) NS protein expression in 16 paired samples of and HCC and para-carcinoma tissues. **P<0.01.</p
