Viral killer

By | August 31, 2001

The ability to selectively kill cells lacking normal p53 activity is an attractive anti-cancer strategy. In the August 30 Nature, Kenneth Raj and colleagues from the Swiss Institute for Experimental Cancer Research (ISREC) suggest that adeno-associated virus (AAV) could be employed as a 'hired assassin' (Nature 2001, 412:914-917).They found that AAV induced apoptosis of p53-deficient osteosarcoma cells, but induced cell-cycle arrest (in G2 phase) in cells expressing p53. None of the proteins enc
