Antisense oligodeoxyribonucleotide down-regulation of bcl-2 gene expression inhibits growth of the low-grade non-Hodgkin's lymphoma cell line WSU-FSCCL.
Establishment and characterization of a new human B-cell line (ONHL-1) from non-Hodgkin's lymphoma: constant expression of bcl-2 gene during mitogen-induced growth inhibition.
In addition, two other genes, BCL6 and BCL2, which are classically related to apoptosis and non-Hodgkin lymphoma, were shown for the first time to be involved in amplification.
In order to clarify the effects of Epstein-Barr virus (EBV) infection on apoptosis and proliferative activity of non-Hodgkin's lymphoma, 135 Japanese lymphoma cases were investigated for the presence of viral RNA and its correlation with bcl-2 protein (Bcl-2) expression.
Interestingly these fragile sites were located in the same chromosomal bands as the oncogenes, MOS, MYC, BCL-1 and BCL-2 as well as cancer breakpoints specifically associated with non-Hodgkin's lymphoma, suggesting the possibility that fragile sites may play a critical role in the pathogenesis of non-Hodgkin's lymphoma.
Multiplex PCR for the detection of BCL-1/IGH and BCL-2/IGH gene rearrangements--clinical validation in a prospective study of blood and bone marrow in 258 patients with or suspected of non-Hodgkin's lymphoma.
MYC/BCL2 double hit lymphoma (DHL) is a rare, recently recognised and highly aggressive subtype of non-Hodgkin lymphoma, with an affinity to involve the central nervous system and the head and neck either at initial presentation or during relapse.
Ongoing clinical trials are exploring the role of Bcl-2 downregulation with oblimersen (Bcl-2 antisense) in patients with non-Hodgkin's lymphoma, chronic lymphocytic leukemia and multiple myeloma.
Other studies have suggested an inverse relationship between p53 and bcl-2 protein expression in breast and colonic cancers and in a variety of subtypes of non-Hodgkin's lymphoma.
Prognostic significance of BCL-2 expression and bcl-2 major breakpoint region rearrangement in diffuse large cell non-Hodgkin's lymphoma: a British National Lymphoma Investigation Study.
