BCL2 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 ( apoptosis), by either inhibiting (anti-apoptotic) or inducing (pro-apoptotic) apoptosis ...

BCL3 B-cell lymphoma 3-encoded protein is a protein that in humans is encoded by the ''BCL3'' gene. This gene is a proto-oncogene candidate. It is identified by its translocation into the immunoglobulin alpha-locus in some cases of B-cell leukemia. ...

mucosa-associated lymphoid tissue (MALT) lymphoma MALT lymphoma (MALToma) is a form of lymphoma involving the mucosa-associated lymphoid tissue (MALT), frequently of the stomach, but virtually any mucosal site can be affected. It is a cancer originating from B cells in the marginal zone of the MAL ...
