ZNF521 and B-cell non-Hodgkin lymphoma: The Zfp521 (zinc finger protein 521) gene was identified as a common integration site 3 (Evi3) in the genomes of B-cell lymphomas in the AKXD mouse strain.45, 55 We also reported that this gene is the most frequent integration site as well in pre-B-cell lymphoma in SL/Kh mice.32 The encoded ZFP521 regulates and activates pre-B-cell receptor signal pathways.45
