The role of oncogenes in hematologic malignancies.

Oncogenes are activated forms of cellular genes involved in normal cell growth and development. Some oncogenes play a role in human malignancies. In hematologic malignancies, researchers have identified many transcription factors as oncogenes based on one of the following criteria: their association with transforming retroviruses in animals, their translocation into either the immunoglobulin or T-cell receptor loci, or the production of fusion proteins resulting from chromosomal translocations. The molecular characterization of oncogenes in hematologic malignancies has led to the discovery of new methods for diagnosis and detection of minimal residual disease. In the future, researchers probably will develop novel treatment strategies to interfere with the function of these oncogenes.
