Abstract
Objective To study the relationship of expression of metastasis suppressor gene nin23-H1 protein in gastric carcinoma tissue and tumor infiltration and metastasis.Methods The expression of metastasis suppressor gene nm23-H1 protein in 50 gastric carcinoma tissues was detected by SP immunohistocbemistry tech-nology.Results Correlations were presented among expression of nm23-H1 protein, infiltrate grade of gastric carcinoma, lymph node metastasis and TNM stage.Conclusions Expression of nm23-H1 may suppress infiltra-tion and metastasis of gastric carcinoma, Low expression of nm23-H1 protein may be of great reference value in judgement of tumor progression, metastasis and reeidivation. Key words: Gastric carcinoma ; nm23-H1 ; Immunohistochemistry ;
