ABSTRACT:
Provided are peptides or mimetics that block corepressor binding to a BCL6 lateral groove. Also provided are methods of blocking corepressor binding to the BCL6 lateral groove. Additionally, methods of inhibiting BCL6 repression in a mammalian, cell, and methods of treating a mammal with cancer are provided.
