The ferroptosis inducer erastin enhances sensitivity of acute myeloid leukemia cells to chemotherapeutic agents
Open accessAbstract
Acute myeloid leukemia (AML) is the most common type of leukemia in adults. Development of resistance to chemotherapeutic agents is a major hurdle in the effective treatment of patients with AML. The quinazolinone derivative erastin was originally identified in a screen for small molecules that exhibit synthetic lethality with expression of the RAS oncogene. This lethality was subsequently shown to occur by induction of a novel form of cell death termed ferroptosis. In this study we demonstrate that erastin enhances the sensitivity of AML cells to chemotherapeutic agents in an RAS-independent manner. Erastin dose-dependently induced mixed types of cell death associated with ferroptosis, apoptosis, necroptosis, and autophagy in HL-60 cells (AML, NRAS_Q61L), but not Jurkat (acute T-cell leukemia, RAS wild type), THP-1 (AML, NRAS_G12D), K562 (chronic myelogenous leukemia, RAS wild type), or NB-4 (acute promyelocytic leukemia M3, KRAS_A18D) cells. Treatment with ferrostatin-1 (a potent ferroptosis inhibitor) or necrostatin-1 (a potent necroptosis inhibitor), but not with Z-VAD-FMK (a general caspase inhibitor) or chloroquine (a potent autophagy inhibitor), prevented erastin-induced growth inhibition in HL-60 cells. Moreover, inhibition of c-JUN N-terminal kinase and p38, but not of extracellular signal-regulated kinase activation, induced resistance to erastin in HL-60 cells. Importantly, low-dose erastin significantly enhanced the anticancer activity of 2 first-line chemotherapeutic drugs (cytarabine/ara-C and doxorubicin/adriamycin) in HL-60 cells. Collectively, the induction of ferroptosis and necroptosis contributed to erastin-induced growth inhibition and overcame drug resistance in AML cells.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
