Chromosome 12q24.1 is a recurrent breakpoint in high-grade B-cell non- Hodgkin lymphoma (B-NHL). To identify the genes involved at 12q24.1, molecular cloning of a three-way translocation t(8;14;12)(q24.1;q32.3;q24.1) in a Burkitt lymphoma cell line (Wien 133) was performed; all four translocation breakpoints were cloned and sequenced. Analysis of clones encompassing the der(12)(12;14)(q24.1;q32.3) breakpoint showed a CpG island from chromosome 12q24.1 juxtaposed in a tail-to-tail configuration with a productively rearranged Ig VH4-DH-JH5 gene. A total of 4.5 kb of genomic DNA including the CpG island was sequenced and analyzed using gene-identification programs; all three programs identified a potential 92-bp exon within the centromeric boundary of the CpG island. Using this as a probe, an RNA transcript of 3.8 kb, expressed at low levels in a wide variety of normal tissues, was detected. Overlapping cDNA clones were isolated and sequenced. The longest open-reading frame predicted a serine-rich protein of 231 amino acids. This protein, termed BCL7A, exhibited no recognizable protein motifs but showed homology with the actin-binding protein, caldesmon. In Wien 133, the BCL7A breakpoint occurred within the first intron and resulted in a MYC- BCL7A fusion transcript, with exon I of BCL7A being replaced by MYC exon I. The normal, untranslocated allele of BCL7A was also expressed without mutation. One of the 11 other B-NHL cell lines examined with 12q24.1 cytogenetic abnormalities, a mediastinal B-NHL cell line (Karpas 1106), showed biallelic rearrangement within the first intron of BCL7A, which was adjacent to the breakpoint observed in Wien 133. Disruption of the amino-terminus of BCL7A defines a new mechanism in the pathogenesis of a subset of high-grade B-NHL.

The Burkitt lymphoma cell line KK124, which contains a reciprocal t(8;22) translocation, was shown to have rearranged in a region 3' to the c-myc proto-oncogene on chromosome 8 and 5' to the lambda constant region on chromosome 22. The breakpoint was cloned and sequenced, revealing that c-myc and a portion of its 3' region abutted a complete lambda variable gene that had undergone V-J recombination. Since this cell line expresses kappa light chain, this lambda rearrangement violates the previously proposed hierarchy of immunoglobulin gene rearrangement. A novel duplication of normal chromosome 8 sequences was also found at the breakpoint. The first exon of c-myc and its flanking sequence from the translocated allele was sequenced and compared with a normal counterpart. Extensive mutation was found within the first exon in contrast to its 3' and 5' flanking regions. S1 nuclease analysis revealed that it was the translocated c-myc being expressed and that there was a promoter shift from P2 to P1. The detailed structural analysis of this cell line provides clues concerning mechanisms of chromosomal translocation and c-myc deregulation in Burkitt lymphomas.

AbstractTissue inhibitor of metalloproteinase 1 (TIMP-1) is a stromal factor with multiple functions. Overexpression of TIMP-1 correlates with aggressive clinical behavior of a spectrum of tumors. Here, for the first time, we address the role of TIMP-1 in the pathogenesis of B-cell lymphomas. An Epstein-Barr virus (EBV)-negative Burkitt lymphoma cell line with ectopic TIMP-1 expression (TIMP-1JD38) was used to identify genes induced/repressed by TIMP-1. Differentially expressed genes were analyzed by cDNA microarray, and they were validated by immunohistochemistry, flow cytometry, and Western blotting. Analysis revealed changes of genes coding for B-cell growth/differentiation, transcription, and cell cycle regulators. TIMP-1 repressed expression of germinal center (GC) markers CD10, Bcl-6, PAX-5 and up-regulated plasma cell-associated antigens CD138, MUM-1/IRF-4, XBP-1, and CD44, suggesting a plasma cell differentiation. This is accompanied by activation of signal transducer and activator of transcription 3 (STAT-3) and switch to cyclin D2 expression. However, TIMP-1JD38 cells expressed an inactive form of XBP-1, lacking antibody production/secretion. This incomplete plasmacytic differentiation occurs without altering cell proliferation, and despite c-Myc deregulation, indicating an arrested plasmacytic/plasmablastic stage of differentiation. Further validation in human lymphoma cell lines and in primary B-cell tumors demonstrated a predominant TIMP-1 expression in tumors with plasmacytic/plasmablastic phenotypes, including multiple myelomas. These findings strongly support TIMP-1 as an important factor in the pathogenesis of plasmacytic/plasmablastic tumors. (Blood. 2005;105:1660-1668)
