BACKGROUND: The outcome of the treatment of pediatric acute myeloid leukemia (AML) is still disappointing, due to relatively high treatment-related mortality and relapse rates (30-40%). Past treatment protocols have called for routine screening via bone marrow aspiration (BMA) after achievement of first complete remission (CR1) to detect relapse at an ...

The core assumption driving the use of conditional loss-of-function reagents such as temperature-sensitive mutations is that the resulting phenotype(s) are solely due to depletion of the mutant protein under nonpermissive conditions. However, prior published data, combined with observations presented here, challenge the generality of this assumption at least for telomere ...
