Abstract

Somatically acquired chromosomal translocations result in the abnormal expression of proteins that may contribute to neoplasia by interfering with or mimicking the action of growth factors and their receptors, signal transducers, or nuclear regulatory proteins and transcription factors, which affect gene expression directly. Oncogenesis mediated by transcription factors is particularly important in the acute leukemias and sarcomas, malignancies in which chromosomal translocations and inversions commonly activate genes encoding transcriptional regulatory proteins (Rowley et al. 1993; Rabbitts 1994). The modular organization of transcription factors provides an ideal mechanism for mediating their multiple effects on cell lineage-specific gene expression: binding to DNA, trans-activation or trans-repression of target genes and protein-protein interactions within complex regulatory networks.
