The cytotoxic effects correlated with apoptosis inductionas was evidenced by increase of apoptotic cells and activation of caspase-3 and caspase-8 upon the treatment of oncrasin-1 in sensitive cells.Treatment with oncrasin-1 also led to abnormal aggregationof PKCι in nucleus of sensitive cells but not in resistant cells.
