Suppression of RUNX1/ETO oncogenic activity by a small molecule inhibitor of tetramerization.

چکیده
RUNX1/ETO, the product of the t(8;21) chromosomal translocation, is required for the onset and maintenance of one of the most common forms of acute myeloid leukemia (AML). RUNX1/ETO has a modular structure and, besides the DNA-binding domain (Runt), contains four evolutionary conserved functional domains named nervy homology regions 1-4 (NHR1 to NHR4). The NHR domains serve as docking sites for a variety of different proteins and, in addition, the NHR2 domain mediates tetramerization through hydrophobic and ionic/polar interactions. Tetramerization is essential for RUNX1/ETO oncogenic activity. Destabilization of the RUNX1/ETO high molecular weight complex abrogates RUNX1/ETO oncogenic activity. Using structure-based virtual screening, we identified several small molecule inhibitors mimicking the tetramerization hot spot within

From Determinants of RUNX1/ETO Tetramerization to Small-Molecule Protein-Protein Interaction Inhibitors Targeting Acute Myeloid Leukemia
We identified the first small-molecule protein-protein interaction inhibitors of RUNX1/ETO tetramerization applying structure-based virtual screening guided by predicted hot spots and pockets in the interface. A 3D similarity screening revealed specific hot spot mimetics, one of which prevents the proliferation of RUNX1/ETO-dependent SKNO-1 cells at low micromolar concentration. Using solely a ...
متن کاملDimer-tetramer transition controls RUNX1/ETO leukemogenic activity.
RUNX1/ETO, the fusion protein resulting from the chromosomal translocation t(8;21), is one of the most frequent translocation products in acute myeloid leukemia. Several in vitro and in vivo studies have shown that the homo-tetramerization domain of ETO, the nervy homology region 2 (NHR2), is essential for RUNX1/ETO oncogenic activity. We analyzed the energetic contribution of individual amino ...

متن کاملTargeting the oligomerization domain of ETO interferes with RUNX1/ETO oncogenic activity in t(8;21)-positive leukemic cells.
About 12% of all de novo acute myeloid leukemias are characterized by the translocation t(8;21), which generates the oncogenic fusion protein RUNX1/ETO. RUNX1/ETO has a modular structure and contains several docking sites for heterologous proteins, including transcriptional co-repressors like N-CoR, SMART, and mSIN3A. RUNX1/ETO is found in high molecular weight complexes, which are crucial for ...
متن کاملInterference with RUNX1/ETO Leukemogenic Function by Cell-Penetrating Peptides Targeting the NHR2 Oligomerization Domain
The leukemia-associated fusion protein RUNX1/ETO is generated by the chromosomal translocation t(8;21) which appears in about 12% of all de novo acute myeloid leukemias (AMLs). Essential for the oncogenic potential of RUNX1/ETO is the oligomerization of the chimeric fusion protein through the nervy homology region 2 (NHR2) within ETO. In previous studies, we have shown that the intracellular ex...
