We compared the intracellular levels of the phosphorylated mTOR target S6RP and the autophagy-associated mediators LC3B, Beclin-1, ATG-3, ATG7, and ATG-10 after 4 hours of incubation in FBS-containing medium for AML cells derived from 9 patients (Figure 1). Here, BECN1 is linked to acute myeloid leukemia.
