Disease relevance of PRDM1

  • Unexpectedly, a subset of diffuse large B-cell lymphoma expressed PRDM1, lacked detectable plasmablastic or immunoblastic changes and displayed more aggressive behavior, with a shorter failure-free survival [1].
  • Altered mRNA expression of Pax5 and Blimp-1 in B cells in multiple myeloma [2].
  • Here we show PRDI-BF1 assembles silent chromatin over the interferon-beta promoter in the osteosarcoma cell line U2OS through recruitment of the histone H3 lysine methyltransferase G9a [3].
  • We report here that the BLIMP1 gene is inactivated by structural alterations in 24% (8 out of 34) activated B cell-like diffuse large cell lymphoma (ABC-DLBCL), but not in GC B cell-like (n = 0/37) or unclassified (n = 0/21) DLBCL [4].
  • Since Pax-5 and Id-2 transcription factors play an opposing role in AID regulation, we have studied the expression of Pax-5, Id-2, and prdm-1 genes in 54 chronic lymphocytic leukemia (CLL) B cells [5].

Anatomical context of PRDM1

 

Physical interactions of PRDM1

  • We hypothesize that premature Blimp-1 expression coupled to altered and deficient Pax5 expression causes some proliferating B cells to prematurely differentiate to plasma cells in MM [2].
  • The results show that Blimp-1 represses the c-myc promoter by an active mechanism that is independent of the adjacently bound activator YY1 [15].
  • Repression of CIITA depends on the DNA binding activity of PRDI-BF1 and its specific binding site in the CIITA promoter [16].
