Eradicating leukemia stem cells
doi:10.1038/scibx.2011.1056
Inhibiting the oncoprotein BCL6 improves the efficacy of tyrosine kinase inhibitors in mouse models of two types of leukemia, suggesting that BCL6 inhibitors already being developed could potentially lead to shorter tyrosine kinase inhibitor treatment.

Inhibition of BET recruitment to chromatin as an effective treatment for MLL-fusion leukaemia
doi:10.1038/nature10509
In this study, a novel small molecule inhibitor of the BET family has been shown to displace BET proteins from chromatin to induce early cell cycle arrest and apoptosis in MLL-fusion leukaemic cell lines and to provide survival benefit in two mouse models of leukaemia.
