Research Abstract |
The t(3 ; 21)(q26 ; q22) translocation is thought to trigger blastic crisis in chronic myelocytic leukemia (CML). This reciprocal translocation generates an AML1/EVI-1 chimeric gene which is transcribed as fusion mRNAs. The 180 kD AML1/EVI-1 fusion protein contains an amino-terminal half of AML1 including a runt homology domain which is fused to the entire of zinc finger EVI-1 protein. The AML1/EVI-1 fusion transcript is consistent among all three cases of the t(3 ; 21)-carrying leukemia examined. Synthetic antisense oligonucleotides complementary to the sequences including the transcriptional initiation sequences of authentic AML1 and EVI-1 specifically suppress growth of leukemia cells with the t(3 ; 21) translocation. These findings strongly suggest that the t(3 ; 21) translocation results in the formation of a new class of a chimeric transcription factor which could contribute to leukemic progression through interference with cell growth and differentiation.
