Effects of inhibitors of plasminogen activator, serine proteinases, and collagenase IV on the invasion of basement membranes by metastatic cells
Reich, R., Thompson, E.W., Iwamoto, Y., Martin, G.R., Deason, J.R., Fuller, G.C., & Miskin, R. (1988) Effects of inhibitors of plasminogen activator, serine proteinases, and collagenase IV on the invasion of basement membranes by metastatic cells. Cancer Research, 48(12), pp. 3307-3312.
Using both human and murine cell lines, we show that malignant cells are able to invade through basement membrane and also secrete elevated amounts of collagenase IV, an enzyme implicated in the degradation of basement membranes. Using serine proteinase inhibitors and antibodies to plasminogen activators as well as a newly described collagenase inhibitor we demonstrate that a protease cascade leads to the activation of an enzyme(s) that cleaves collagen IV. Inhibition at each step reduces the invasion of the tumor cells through reconstituted basement membrane in vitro. Treatment with a collagenase inhibitor reduced the incidence of lung lesions in mice given i.v. injections of malignant melanoma cells.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
