Abstract

The ARF tumor suppressor gene antagonizes generation of various tumors. ARF-mediated tumor suppression occurs in a p53-independent manner as well as in a p53-dependent manner. We here demonstrate that BCL6 is a target of the ARF tumor suppressor. Either mouse p19(ARF) or human p14(ARF) binds to BCL6 and downregulates BCL6-induced transcriptional repression. ARF-mediated downregulation of the BCL6 activity may account in part for ARF-mediated tumor suppression.
