As a critical cellular stress sensor, p53 mediates a variety of defensive processes including cell-cycle arrest, apoptosis, and senescence to prevent propagation of hyperproliferative cells or cells with a damaged genome, hence the formation of neoplasia. Transactivation of downstream genes plays an...

Salivary tumors isolated from MMTV-ras transgenic mice expressing wild-type p53, no p53 or p53R172H gain-of-funcion mutant were subjected to genome-wide gene expression profiling to assess the effect of the different p53 status on tumor gene expression. A total of 12 spontaneous salivary tumors from...
