Gene expression profiling for improved dissection of acute leukemia: A recently identified immature myeloid/T-lymphoid subgroup as an example

In this concise overview, we discuss recent findings concerning a distinct subgroup of acute myeloid/T-lymphoid leukemia. We describe how we identified these leukemias in multiple cohorts of acute myeloid leukemia (AML) using a combination of gene expression profiling and additional analytic approaches, and how we obtained insight in possible mechanisms leading to their phenotype.
