Correlation of collagenase secretion with metastatic-colonization potential in naturally occurring murine mammary tumours.
We report evidence for the secretion of a true mammalian collagenase active against Type 1 collagen, by naturally-occurring mammary tumours of the mouse and show that tumours capable of heavily colonizing the lungs secrete significantly more of this enzyme than those with low pulmonary-colonization...

description | We report evidence for the secretion of a true mammalian collagenase active against Type 1 collagen, by naturally-occurring mammary tumours of the mouse and show that tumours capable of heavily colonizing the lungs secrete significantly more of this enzyme than those with low pulmonary-colonization potential, or non-neoplastic proliferating (e.g. lactating) mammary tissue. Plasminogen activator is secreted in greater quantity by tumours than by normal tissues, but there is no significant difference in the amount produced by tumours with high or low pulmonary-colonization potential. These findings correlate well with our earlier morphological observations of marked connective tissue destruction in the vicinity of invading tumours and metastatic deposits, and indicate that protease release is implicated in the mechanism of tumour spread.
