We describe a case of blastoid mantle cell lymphoma with a complex karyotype. The blastoid variant is a rare type of non-Hodgkin lymphoma exhibiting an aggressive clinical course. Mantle cell lymphoma is a distinct entity of mature B-cell neoplasms genetically characterized by the presence of t(11;14). In the present case, conventional analysis revealed structural abnormalities of chromosomes 2...
The product of the retinoblastoma tumor-suppressor gene (pRB), a nuclear phosphoprotein that regulates transcription factors such as E2F, is involved in cell cycle control and differentiation. Its activity is regulated by phosphorylation; the underphosphorylated form inhibits transcription whereas the highly phosphorylated form is inactive. Cyclin D1 and its associated kinase (CDK 4/6) phosphor...
Translocations involving the IgH locus at chromosomal locus 14q32.3 are a common event in many B-cell malignancies. The translocations, which generally occur into JH and switch regions, are mediated by errors in the two developmentally regulated, lymphocyte-specific pathways: VDJ-and switch-mediated recombination. Dysregulation of cyclin D1 by a t(11;14)(q13;q32) translocation occurs in most ca...
Mantle cell lymphoma is an incurable and generally aggressive lymphoma that is more common in elderly patients. Whilst a number of different chemotherapeutic regimens are active in this disease, there is no established gold standard therapy. Rituximab has been used widely to good effect in B-cell malignancies but there is no evidence that it improves outcomes when added to chemotherapy in this ...
Materials/Method: To examine the relationship between BIM protein expression and genomic BIM loss, we performed Western blotting analysis using whole cell lysates of the seven MCL cell lines. This expression was compared to the results of array CGH, especially for the relationship with BCL2, the antagonist of BIM. In order to understand the relevance of apoptosis-related genes in MCL, published...
Mantle cell lymphoma is an uncommon lymphoma subtype that is currently considered incurable and lacks a single standard of care. Choice of treatment is complicated by the disease’s clinical heterogeneity. The course of the disease may be indolent, moderately aggressive, or aggressive. A translocation between chromosomes 11 and 14 is observed in the majority of mantle cell lymphoma patients, and...
Chromosomal rearrangements observed in T-cell prolymphocytic leukemia involve the translocation of one T-cell receptor gene to either chromosome 14q32 or Xq28, deregulating the expression of cellular protooncogenes of unknown function, such as TCL1 or its homologue, MTCP1. In the human hematopoietic system, TCL1 expression is predominantly observed in developing B lymphocytes, whereas its overe...
