Objective To investigate the expression of FOXC-2, YB-1 and related proteins and their influences on development, invasion and metastases in gastric carcinoma.MethodsA total of 193 tissue samples were collected, including 50 cases of normal gastric mucosa,50 cases of gastric mucosal intraepithelial neoplasia and 93 cases of primary gastric carcinoma. The 93 cases of primary gastric carcinoma included 74 cases of positive lymph node metastasis tissues,19 cases of nonmetastasis tissues and 33 cases of distant metastasis tissues. Immuohistochemistry was used to detect the expression and distribution of FOXC-2, YB-1, E-cadherin,Vimentin and MMP-2 in normal and intraepithelial neoplasia, gastric carcinoma, positive lymph node metastasis tissues and distant metastasis tissues. ResultsThe expressions of FOXC-2, YB-1, Vimentin and MMP-2 in gastric carcinoma were significantly higher than those in normal and intraepithelial neoplasia while the expression of E-cadherin was significantly lower (PPPPP
