Presence of activated ras correlates with increased cysteine proteinase activities in human colorectal carcinomas.

Abstract excerpt

The metastatic potential of ras-transfected cells has been attributed in part to significant ras induction of proteinase expression. To determine whether primary cancers also demonstrate higher cysteine proteinase activities in the presence of activated ras genes or altered ras protein expression, we have analyzed 60 primary human colorectal carcinomas for ras gene or protein changes together with the expression...
