abstract：:Cross-linking of the IgM antigen receptor on an immature B cell lymphoma (BKS-2) induces growth arrest and apoptosis. This is accompanied by down-regulation of the immediate early genes, egr-1 and c-myc, and a reduction in NF-kappaB activity. Anti-IgM-induced growth arrest and apoptosis of this murine B cell lymphoma ...
