Transcription factors with significantly altered expression in plasma cells.

Twenty-three transcription factors were induced or up-regulated in plasma cells versus B cells, whereas 89 transcription factors were lost or down-regulated. The genes are listed according to the cluster analysis, which groups genes based on the relatedness of the expression pattern. Each of these genes displayed a statistically significant 2-fold or greater difference in expression between plasma cells and B cells. *Genes for which quantitative RT-PCR was performed (Table1).
