Abstract

The secretion of matrix metalloproteinases (MMPs), which enzymes have been suggested as degradative agents for components of the extracellular matrix, was studied in eight glioma cell lines. We investigated the relationship between the secretion of MMPs and the tumorigenicity of the glioma cells by immunoblot analysis using antisera against human MMPs. Four types of matrix metalloproteinase including MMP-1, MMP-2, MMP-3 and MMP-9 were detected in the glioma cells. MMP-2 was detected in all high-grade gliomas, while an additional MMP or two were detected in only two cell lines, U87MG and KINGS-1. Furthermore, the tumorigenetic potential was shown to correlate with the secretion of MMPs in vitro. These enzymes are capable of degrading several extracellular matrix components of the central nervous system, and thus must play an important role in the mechanism of occurence and/or growth of glioma.
