For example, given the essential role of BCL6 BTB domain in recruiting SMRT, NCoR and BCoR corepressors, small cell-penetrating peptide or compounds targeting the BCL6-BTB lateral groove pocket have been designed/identified, which are capable of killing B-cell lymphomas by inhibiting BCL6’s repressor function (192, 193). This evidence concerns the gene BCL6 and B-cell non-Hodgkin lymphoma.
