Cleavage of minerals

WebIn osteoblasts undergoing apoptosis, proteolytic cleavage of N-cadherin and β- and γ- catenins but not α-catenin was associated with the activation of caspase-3 and prevented by the caspase inhibitor Z-VAD-fmk. The pattern of cadherin/catenin cleavage detected in apoptotic osteoblasts was reproduced in vitro by recombinant caspase-3.
