the relevance of these biochemical studies to the pathogenesis of malignant neoplasms is shown by : 1 ) the evaluation of degradative activities of b16 tumor cell populations exhibiting enhanced lung-colonizing phenotypes , and 2 ) the ability of a known antimetastatic moiety with antiprotease activity ( haementeria leech species salivary gland extract ) to protect matrix components from degradation by tumor cell-conditioned medium .
