A Knockout Combo:Eradicating AML Stem Cells with TKI plus SIRT1 Inhibition

SIRT1 inhibition facilitates elimination of CML stem cells by Imatinib, in part via p53 activation. In this issue of Cell Stem Cell, Li et al. (2014) demonstrate a similar role for SIRT1 inhibition in eradicating FLT3-ITD AML stem cells, potentially through a positive feedback loop with c-MYC, highlighting SIRT1 as a potential target in combination cancer therapy.
