New form of programmed cell death has cancer treatment implications

Key clinical point: Ferroptosis, a distinct form of regulated cell death process involving iron-dependent lipid peroxidation, may impact the action of chemotherapy drug decitabine.

Major finding: The level of GSH and the activity of GPX4 decreased, whereas the ROS level increased in MDS cells upon treatment with decitabine, which could be reversed by ferrostatin-1.

Study details: The data come from a review of cell viability assays, reactive oxygen species assays, gluthiathone assays, and

Disclosures: The study was supported in part by the National Natural Science Foundation of China, Key Technology Research and Development Program of Tianjin, Application Bases and Advanced Technology Research Program of Tianjin, and Key National Natural Science Foundation of Tianjin. The researchers had no financial conflicts to disclose.
