"Our data provide important evidence that BCR signaling plays a crucial role in ABC DLBCL," says study senior author Dr. Louis M. Staudt of NCI. Nat Genet . What causes lymphoma is not well known. New genetic mutations found for non-Hodgkin lymphoma. However, as lymphoma incidence rises and research accelerates, several risk factors for lymphoma … "However, more research is needed to understand the various biochemical mechanisms by which chronic, active BCR signaling begins," said Staudt. Alterations in signaling pathways have been found in many types of cancer cells. The most common known genetic change associated with this condition is a mutation in the MYD88 gene, which is found in more than 90 percent of affected individuals. Over the past decade, it has become clear that oncogenesis is a process driven by a wide variety of triggers including gene mutations, gene amplifications, inflammation, and immune deficiency. Thus, ongoing BCR signaling is necessary for ABC subtype DLBCL cells to survive. The mutation increased BCR signaling by raising the amount of BCRs on the cell surface and by blocking a process that normally turns off the pathway. In all, we sequenced 73 DLBCL primary tumors (34 with matched normal DNA). Chronic Active B Cell Receptor Signaling in Diffuse Large B Cell Lymphoma.
