Suppresses apoptosis in a variety of cell systems including factor-dependent lymphohematopoietic and neural cells. Regulates cell death by controlling the mitochondrial membrane permeability. Appears to function in a feedback loop system with caspases. Inhibits caspase activity either by preventing the release of cytochrome c from the mitochondria and/or by binding to the apoptosis-activating.

Primary mediastinal large B-cell lymphoma (PMBCL) is one such entity with distinct clinical, pathologic, and genetic features [1, 2] and is believed to arise from thymic medullary B cells, suggesting a unique histogenesis. It accounts for approximately 2% of patients with NHL, with a.

Micro-AbstractWe investigated the significance of BCL-2 and BCL-6 expression in MYC+ diffuse large B-cell lymphoma. Immunohistochemistry was performed to evaluate the expression of BCL-2, BCL-6, and MYC. BCL-2 played a more important role than MYC in patients with double-expression lymphoma. Besides, BCL-6− expression might also be a negative prognostic factor for such patients.

Bcl-2 (B-cell lymphoma 2), encoded in humans by the BCL2 gene, is the founding member of the Bcl-2 family of regulator proteins that regulate cell death (), by either inhibiting (anti-apoptotic) or inducing (pro-apoptotic) apoptosis. Bcl-2 derives its name from B-cell lymphoma 2, as it is the second member of a range of proteins initially described in chromosomal translocations involving.

Note: BCL2 is a proto-oncogene, initially cloned as the result of its consistent involvement by t(14;18)(q32;q21) in lymphoma where its transcription becomes driven by the immunoglobulin heavy chain (IGH) gene enhancer on chromosome 14q32, subsequently leading to constitutive expression of BCL2 in B-cell clones (Tsujimoto et al, 1984, Bakhshi et al, 1985).
