Most existing chemotherapeutics lack adequate specificity for transformed cells and therefore have high rates of collateral damage to normal tissue. Moreover, such therapies often depend on p53 to induce cell death and are ineffective on the large number of human cancers that have lost p53 function. The discovery of novel p53-independent cancer therapies is therefore of significant interest. The Chicken Anemia Virus protein Apoptin selectively induces apoptosis in transformed cells in a p53-independent manner while leaving normal primary cells unaffected. This selectivity is thought to be largely due to cell type-specific localization: in primary cells Apoptin is cytoplasmic, whereas in ...
