abstract = {The heterogeneous response of acute myeloid leukemia (AML)
to current anti-leukemic therapies is only partially
explained by mutational heterogeneity. We previously
identified GPR56 as a surface marker associated with poor
outcome across genetic groups, which characterizes two
leukemia stem cell (LSC)-enriched compartments with
different self-renewal capacities. How these compartments
self-renew remained unclear. Here, we show that GPR56+ LSC
compartments are promoted in a complex network involving
epithelial-to-mesenchymal transition (EMT) regulators
besides Rho, Wnt, and Hedgehog (Hh) signaling. Unexpectedly,
Wnt pathway inhibition increased the more immature, slowly
cycling GPR56+ CD34+ fraction and Hh/EMT gene expression,
while Wnt activation caused opposite effects. Our data
suggest that the crucial role of GPR56 lies in its ability
to co-activate these opposing signals, thus ensuring the
constant supply of both LSC subsets. We show that CDK7
inhibitors suppress both LSC-enriched subsets in vivo and
synergize with the Bcl-2 inhibitor venetoclax. Our data
establish reciprocal transition between LSC compartments as
a novel concept underlying the poor outcome in GPR56high AML
and propose combined CDK7 and Bcl-2 inhibition as
LSC-directed therapy in this disease.},
