Abstract

Cell death is a complex process that plays a vital role in development, homeostasis, and disease. Our understanding of and ability to control cell death is impeded by an incomplete characterization of the full range of cell death processes that occur in mammalian systems, especially in response to exogenous perturbations. We present here a general approach to address this problem, which we call modulatory profiling. Modulatory profiles are composed of the changes in potency and efficacy of lethal compounds produced by a second cell death-modulating agent in human cell lines. We show that compounds with the same characterized mechanism of action have similar modulatory profiles. Furthermore, clustering of modulatory profiles revealed relationships not evident when clustering lethal compounds based on gene expression profiles alone. Finally, modulatory profiling of compounds correctly predicted three previously uncharacterized compounds to be microtubule-destabilizing agents, classified numerous compounds that act nonspecifically, and identified compounds that cause cell death through a mechanism that is morphologically and biochemically distinct from previously established ones.

  • 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].”

    From Ferroptosis: Death by Lipid Peroxidation (2016) · cites this paper as [14]

  • In modulatory profiling, erastin and RSL3 cluster together, suggesting they share a cell death mechanism.

    “Using modulatory profiling, an unbiased pharmacological and genetic profiling system in which lethal compounds are classified based on their functional profiles [14, 18], erastin and RSL3 were found to cluster together, suggesting that they share a similar cell death mechanism.”

    From Ferroptosis: Death by Lipid Peroxidation (2016) · cites this paper as [14]

  • Ferroptosis is an iron-dependent autophagic cell death program that can be inhibited in MEFs by genetically inactivating autophagy or ferritinophagy.

    “an iron-dependent autophagic cell death program [62], [63], [64] that can be inhibited in MEFs by genetically inactivating autophagy or ferritinophagy [65].”

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.
