ZBTB7A and diffuse large B-cell lymphoma: Moreover, given the overlapped expression and function of BCL6 and ZBTB7A in GC-B cells (54), and the formation of BCL6/ZBTB7A heterodimers in malignant DLBCL/FL cells (53, 77), it is likely that they collaborate in modulating cellular functions (Figure 2C).
