β-catenin accumulation in nuclei of hepatocellular carcinoma cells up-regulates glutathione-s-transferase M3 mRNA

Figure 2 Levels of glutamine synthetase and glutathione-s-transferase M3 mRNA and expression of β-catenin. A: T denotes surgically resected B6C3F1 mouse hepatocellular carcinoma (HCC) tissue samples and N denotes matched nontumorous liver tissue samples; B: Representative immunofluorescence photomicrographs for β-catenin (red photomicrographs) in HCC tissue samples. B1 denotes negative β-catenin staining in nuclei of HCC cells, B2 denotes positive β-catenin staining in nuclei of HCC cells, and white arrows indicate β-catenin detected in nuclei of HCC cells. Bars: 50 μm. GLNS: Glutamine synthetase; GSTM3: Glutathione-s-transferase M3.
