Homeobox Msx1 Interacts with p53 Tumor Suppressor and Inhibits Tumor Growth by Inducing Apoptosis
1 Feb 2005
Abstract excerpt
The stability of wild-type p53 is critical for its apoptotic function. In some cancers, wild-type p53 is inactivated by interaction with viral and cellular proteins, and restoration of its activity has therapeutic potential. Here, we identify homeobox Msx1 as a p53-interacting protein and show its novel function as a p53 regulator. Overexpression of homeobox Msx1 induced apoptosis of cancer cells harboring...
