abstract：:One reported function of the tumor suppressor p19(Arf) is to stabilize p53, providing a critical checkpoint in the response to oncogenic insults. Acute loss of Pten leads to an increase in the abundance of p19(Arf), p53, and p21 proteins as part of a fail-safe senescence response. Here, we report that loss of p19(Arf)...
