  • Effect of the Enhanced Expression of Gelatinase A Gene on the Invasion and Metastasis of Human Gastric Carcinoma

    Objective To investigate the effect of mRNA expression of gelatinase A on the invasion and metastasis of human gastric carcinoma (HGC). MethodsThirtysix cases of HGC were examined by in situ hybridization technique. ResultsPositive expression rates of gelatinase A in the normal gastric tissue, peritumor tissue and HGC were 8.3%,35.7% and 83.3% respectively (P<0.01). The positive rates of gelatinase A in the group with serosal invasion and lymph node metastasis were 93.1% and 90.6%, much higher than those in the group with negative ones (42.9% and 25.0%).By in situ hybridization, gelatinase A mRNA was showed to be expressed in the extracellular matrix of tumor tissues,which surrounded the invasive margin of cancer tissues. The positive cells at these sites were mainly tumorinfiltrating macrophages. Conclusion There is good correlation between gelatinase A mRNA expression and the invasion, metastasis of HGC. So it can be used as a useful marker for invasion and metastasis of HGC.
