The activity of caspase-3-like proteases is elevated during the development of colorectal carcinoma

Activated caspase-3-like proteases promote apoptotic cell death by cleaving cellular substrates. Caspase-3-like activity was measured in colonic carcinomas and in matched normal colonic mucosa from 31 patients and was significantly elevated in 25/31 colonic carcinomas and adenomas when compared to n...
