miRNA profiling of B-cell subsets: specific miRNA profile for germinal center B cells with variation between centroblasts and centrocytes.

MicroRNAs (miRNAs) are an important class of small RNAs that regulate gene expression at the post-transcriptional level. It has become evident that miRNAs are involved in hematopoiesis, and that deregulation of miRNAs may give rise to hematopoietic malignancies. The aim of our study was to establish miRNA profiles of naïve, germinal center (GC) and memory B cells, and validate their expression patterns in normal lymphoid tissues.

Hodgkin lymphoma cell lines are characterized by a specific miRNA expression profile.

Hodgkin lymphoma (HL) is derived from preapoptotic germinal center B cells, although a general loss of B cell phenotype is noted. Using quantitative reverse transcription-polymerase chain reaction and miRNA microarray, we determined the microRNA (miRNA) profile of HL and compared this with the profile of a panel of B-cell non-Hodgkin lymphomas. The two methods showed a strong correlation for the detection of miRNA expression levels.
