The PRDM1 gene, a master regulator of plasma cells (PC), can generate two transcription factor isoforms: PRDI-BF1alpha and PRDI-BF1beta. The present study shows that purified human normal PC have a significantly lower levels of PRDI-BF1beta expression than that in tumoral PC isolated from multiple myeloma (MM) (0.06+/-0.01 and 0.25+/-0.05, respectively; p<0.001). The role of this finding in MM is discussed.
