Abstract
Matrix metalloproteinase (MMP) has been reported to play an important role in the process of tumor development and metastasis through the alterations of cell-cell and/or cell-extracellular matrix interactions. We studied the gene expression of matrix metalloproteinase MMP-2 and MMP-7, and also TIMP-1, one of the inhibitors of metalloproteinase, in the tissue of human hepatocellular carcinoma by using semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) method. MMP-2 and MMP-7 have been expressed in advanced hepatocellular carcinomas as well as in non-cancerous, chronically diseased liver tissue, and the expression levels of these MMPs in human hepatocellular carcinoma (HCC) tissues were greater than that of non-cancerous tissues. This data suggests that MMP-2 and MMP-7 may be involved in the process of the development, invasion and metastasis of HCCs.
