摘要
Imetelstat is a first-in-class telomerase inhibitor with efficacy in a number of blood cancers. Intriguingly, telomere lengths do not predict patient responses to imetelstat. We now show that imetelstat causes cell death by a mechanism that involves two regulators of fatty acid metabolism (FADS2 and ACSL4), driving excessive lipid reactive oxygen species formation and ferroptosis.
