Angiostatin directly inhibits human prostate tumor cell invasion by blocking plasminogen binding to its cellular receptor, CD26.


Previous studies demonstrate that one of the six plasminogen type 2 glycoforms, plasminogen 2epsilon, enhances invasiveness of the 1-LN human prostate tumor cell line in an in vitro model. Binding of plasminogen 2epsilon to CD26 on the cell surface induces a Ca(2+) signaling cascade which stimulates the expression of matrix metalloproteinase-9, required by… (More)
