Abstract

We used synthetic lethal high-throughput screening to interrogate 23,550 compounds for their ability to kill engineered tumorigenic cells but not their isogenic normal cell counterparts. We identified known and novel compounds with genotype-selective activity, including doxorubicin, daunorubicin, mitoxantrone, camptothecin, sangivamycin, echinomycin, bouvardin, NSC146109, and a novel compound that we named erastin. These compounds have increased activity in the presence of hTERT, the SV40 large and small T oncoproteins, the human papillomavirus type 16 (HPV) E6 and E7 oncoproteins, and oncogenic HRAS. We found that overexpressing hTERT and either E7 or LT increased expression of topoisomerase 2alpha and that overexpressing RAS(V12) and ST both increased expression of topoisomerase 1 and sensitized cells to a nonapoptotic cell death process initiated by erastin.

  • Erastin- and RSL3-induced death is non-apoptotic, occurring without apoptotic hallmarks and even when core apoptosis machinery is suppressed.

    “The mode of cell death induced by these compounds was surprisingly found to be non-apoptotic, as cells treated with erastin and RSL3 died in the absence of apoptotic hallmarks [11, 12, 13], and in cells where the core apoptosis machinery – caspases, BAX, and BAK was suppressed [14].”

  • Erastin and RSL3 were the first compounds found to induce ferroptosis, identified through high-throughput small-molecule screening.

    “The first ferroptosis-inducing compounds, erastin [11] and RSL3 [12], were discovered using high-throughout screening of small molecule libraries [11, 12].”

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.
