EIF4A1 and acute myeloid leukemia: Conditioned media from coculture or EVs isolated from BMSCs (but not AML cells) similarly rescued the translation in AML blasts pre-treated with eIF4Ai; most importantly, this translational boost was abrogated when pre-treating BMSC-derived EVs with eIF4Ai (Figures 6H, 6I, S5H, and S5I), confirming the role of EV-derived eIF4A in AML translation.
