Hodgkin lymphoma (HL) is a malignancy of germinal center (GC) B-cell origin. To explore the role of long noncoding RNAs (lncRNAs) in HL, we studied LncRNA expression patterns in normal B-cell subsets, HL cell lines, and tissues. Naive and memory B cells showed a highly similar lncRNA expression pattern, distinct from GC-B cells. Significant differential expression between I-IL and normal GC-B cells was observed for 475 lncRNA loci. For two validated lncRNAs, an enhanced expression was observed in HL, diffuse large 6-cell lymphoma, and lymphoblastoid cell lines. For a third lncRNA, increased expression levels were observed in HL and part of Burkitt lymphoma cell lines. RNA fluorescence in situ hybridization on primary HL tissues revealed a tumor cell specific expression pattern for all three lncRNAs. A potential cis-regulatory role was observed for 107 differentially expressed lncRNA-mRNA pairs localizing within a 60-kb region. Consistent with a cis-acting role, we showed a preferential nuclear localization for two selected candidates. Thus, we showed dynamic lncRNA expression changes during the transit of normal B cells through the pC reaction and widely deregulated lncRNA expression patterns in HL. Three lncRNAs showed a tumor cell specific expression pattern in HL tissues and might therefore be of value as a biomarker.
