abstract = {Protein synthesis is an essential process, deregulated in
multiple tumor types showing differential dependence on
translation factors compared to untransformed tissue. We
show that colorectal cancer (CRC) with loss-of-function
mutation in the APC tumor suppressor depends on an oncogenic
translation program regulated by the ability to sense
phosphorylated eIF2α (p-eIF2α). Despite increased protein
synthesis rates following APC loss, eIF2α phosphorylation,
typically associated with translation inhibition, is
enhanced in CRC. Elevated p-eIF2α, and its proper sensing
by the decameric eIF2B complex, are essential to balance
translation. Knockdown or mutation of eIF2Bα and eIF2Bδ,
two eIF2B subunits responsible for sensing p-eIF2α, impairs
CRC viability, demonstrating that the eIF2B/p-eIF2α nexus
is vital for CRC. Specifically, the decameric eIF2B linked
by two eIF2Bα subunits is critical for translating
growth-promoting mRNAs which are induced upon APC loss.
Depletion of eIF2Bα in APC-deficient murine and
patient-derived organoids establishes a therapeutic window,
validating eIF2Bα as a target for clinical intervention. In
conclusion, we demonstrate how the expression of the
oncogenic signature in CRC is crucially controlled at the
translational level.},
