The Arf tumor suppressor protein inhibits Miz1 to suppress cell adhesion and induce apoptosis.

Importantly, 64 of the 126 genes were also repressed when Miz1 and Arf were coexpressed, identifying a highly significant overlap in target genes (P = 2.5 × 10 −92 ) and defining a core program of genes that are jointly repressed by Myc and Miz1 in the presence of Arf ( Fig. 6 b ).
