BCR and diffuse large B-cell lymphoma: Furthermore, the lack of BLIMP1 expression correlated with an impaired p53 signaling pathway and Myc overexpression; gene expression profiling data also indicated that inactivated BLIMP1 could facilitate DLBCL progression through Myc and BCR (B cell receptor) signaling, which are essential for ABC-DLBCL survival [26].
