Abstract excerpt
Interleukin (IL)-1beta is constitutively expressed in many leukemias and operates as an autocrine growth factor. To study the cellular basis for this aberrant production, we analyzed two cell lines, B1 (acute lymphoblastic leukemia) and W1 (juvenile chronic myelogenous leukemia), which express high levels of IL-1beta and have mutations in the K-RAS and N-RAS genes, respectively. Electromobility shift assays...
