Fig 1: Expression of S100A6 and SOD3 proteins in the mesenchyma of NGM and GMAH tissues. (A) The expression of S100A6 and SOD3 proteins in NGM and GMAH mesenchymal tissues were detected by western blot analysis. Expression levels of proteins in two tissues were determined by densitometric analysis (n=3; *P<0.01 vs. NGM). (B) Immunohistochemistry revealed the expression of the S100A6 protein in NGM and GMAH mesenchyma. Original magnification, ×10 (left) and ×40 (right). (C) Immunohistochemistry revealed the expression of the SOD3 protein in NGM and GMAH mesenchyma. Original magnification, ×10 (left) and ×40 (right). S100A6, S100 calcium-binding protein A6; SOD3, superoxide dismutase 3; NGM, normal gastric mucosa; GMAH, gastric mucosal atypical hyperplasia.
