The regulation of BCL2 protein expression in germinal center (GC) B cells has been controversial. Previous reports have indicated post-transcriptional regulation plays a dominant role. However, a number of recent studies contradicted these reports. Using Real-Time PCR and StaRT-PCR, we measured the level of mRNA expression in GC, mantle zone (MNZ) and marginal zone (MGZ) cells from laser capture microdissection. Both quantitative RT-PCR measurements of microdissected GC cells from tonsils showed that GC cells had low expression of BCL2 transcripts commensurate with the low protein expression level. These results are in agreement with microarray studies on FACS sorted cells and microdissected GC cells. We also examined BCL2 mRNA and protein expression on a series of thirty cases of diffuse large B cell lymphoma (DLBCL) and found in general, a good correlation. The results suggested that BCL2 protein expression is regulated at the transcriptional level in normal B-cells and in the neoplastic cells in most B-cell lymphoproliferative disorders.
