Transforming genes in chronic myelogenous leukemia
- Univ. of California, San Francisco (USA)
Chronic myelogenous leukemia (CML) is a hematopoietic malignancy characterized by an indolent chronic phase that invariably leads to a blast crisis indistinguishable from acute leukemia. Using a sensitive assay based on gene transfer and tumorigenesis, the authors sought evidence that damage to protooncogenes might figure in the progression from the chronic to the blast phase of CML. Seven of the 12 patients with CML examined in this manner harbored transforming genes. Mutations in RAS protooncogenes were detected in the leukemic cells from 1 or 6 chronic-phase patients, and 3 of 6 blast-crisis patients. In addition, a presently unidentified transforming gene (neither RAS nor RAF) was detected in 1 patient with chronic phase and 1 with blast crisis. These data indicate that mutations in RAS genes may play diverse roles in the pathogenesis of CML.
