Targeting oncogenic fusion genes in leukemias and lymphomas by RNA interference

Leukemias and lymphomas are often characterized by non-random chromosomal translocations that, at the molecular level, induce the activation of specific oncogenes or create novel chimeric genes. They have frequently been regarded as optimal targets for gene-silencing approaches because of the large body of evidence that these single abnormalities directly initiate and maintain the malignant process. Herein, we discuss RNA interference (RNAi)-based approaches for targeting the fusion sites of chromosomal translocations as a future treatment option in leukemias and lymphomas.
