Growth regulators in connective tissue. Systemic administration of an aortic extract inhibits tumor growth in mice

R Eisenstein et al. Am J Pathol. 1978 Apr.

Abstract

A low-molecular-weight fraction prepared from extracts of bovine aorta inhibits the growth of a transplantable mammary tumor and a fibrosarcoma in mice when injected systemically. It also inhibits the growth of the fibrosarcoma in cell culture. The effect on the fibrosarcoma is much more marked than on the mammary tumor. Since the extract is more effective against the fibrosarcoma and is known to inhibit the growth of endothelial cells, it appears that the enhanced effect on this tumor is due to its activity on the endothelial cells of the host and the tumor cells themselves. The material injected is enriched in an antiproteinase we have previously isolated, which has anticollagneolytic activity and is presumed to be the effector molecule.
