Epigenetic regulation of tumor suppressors in t(8:21)-containing AML

Ann Hematol. 2004 Jun;83(6):329-30. doi: 10.1007/s00277-003-0841-8. Epub 2004 Mar 30.

Abstract

The t(8;21) is perhaps the most frequent chromosomal translocation associated with acute myeloid leukemia. The translocation creates a fusion protein that consists of the DNA binding domain of the RUNX1 transcription factor fused to the MTG8 transcriptional co-repressor to create a potent transcriptional repressor. Here, we discuss the possibility that the t(8;21) fusion protein represses tumor suppressors that regulate the RAS signaling pathway and the p53 oncogenic checkpoint.
