BCL6 suppression of BCL2 via Miz1 and its disruption in diffuse large B cell lymphoma.
The BCL6 proto-oncogene encodes a transcriptional repressor that is required for germinal center (GC) formation and whose deregulation by genomic lesions is implicated in the pathogenesis of GC-derived diffuse large B cell lymphoma (DLBCL) and, less frequently, follicular lymphoma (FL). The biological function of BCL6 is only partially understood because no more than a few genes have been funct...
متن کاملMutations of the BCL6 proto-oncogene disrupt its negative autoregulation in diffuse large B-cell lymphoma.
The BCL6 proto-oncogene encodes a transcriptional repressor whose expression is deregulated by chromosomal translocations in approximately 40% of diffuse large B-cell lymphomas (DLBCLs). The BCL6 regulatory sequences are also targeted by somatic hypermutation in germinal center (GC) B cells and in a fraction of all GC-derived lymphomas. However, the functional consequences of these mutations ar...
متن کاملThe epigenetic regulator CTCF modulates BCL6 in lymphoma.
Despite the improvements in the diagnosis and in the approaches to treatment, aggressive lymphomas are still an important cause of morbidity and mortality. There is, therefore, considerable interest in understanding the mechanisms involved in the process of lymphomagenesis. Germinal centers are dynamic structures within the lymph nodes containing highly proliferating B-cells that are undergoing...
متن کاملDeficiency of the Transcriptional Repressor B Cell Lymphoma 6 (Bcl6) Is Accompanied by Dysregulated Lipid Metabolism
The transcriptional repressor B-cell Lymphoma 6 (Bcl6) was recently identified in a profile of genes regulated in adipocytes, suggesting a relationship between Bcl6 and metabolic regulation. As a representative target gene repressed by Bcl6, Suppressor of Cytokine Signaling (Socs) 2 expression was elevated in Bcl6 deficient (KO) mice, including metabolic tissues liver, adipose tissue and muscle...
متن کاملHISTIOCYTE-RICH B-CELL LYMPHOMA: A CASE REPORT OF A RARE VARIANT OF DIFFUSE LARGE B-CELL LYMPHOMA
The authors describe a case of histiocyte-rich B-cell lymphoma (HR-BCL), a variant of diffuse large B-cell lymphoma, in a 51-year-old man. The patient presented with large axillary lymphadenopathy. Histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic CD20 positive B cells. ...
