Abstract
The expression of matrix metalloproteinase-1 (MMP-1) gene and the presence of MMP-1 protein in gastric cancer were examined by in situ hybridization and immunohistochemistry. Expression of the interstitial collagenase (MMP-1) gene was detected within the stroma of the neoplastic glands, and infiltration of eosinophils was observed to be associated with regions of MMP-1 gene expression. The degree of eosinophilic infiltration correlated with the level of MMP-1 mRNA expression. Immunostaining showed localization of MMP-1 protein in the stromal cells, and additionally in the neoplastic glands. These findings indicate that the stromal cells may play an important role in the expression of MMP-1, and suggest a pathophysiological role for MMP-1 in the invasion and metastasis of gastric cancer.Entities:
