Erastin and gpx4
WebOct 2, 2024 · Ferroptosis is characterized by systemXc −, GPX4, ferrous ions and other biomolecules. Small exogenous molecules, changes in the cellular environment, changes in the activity/function of key biomolecules, abnormal levels of key cellular molecules, and metabolic disturbances can affect ferroptosis. WebJW, AMM, and XJ conceived the original idea and designed the study. JW and AMM carried out most experiments. MG, HB, and YL generated multiple reagents and the inducible GPX4 knockout used in animal experiments. BRS supplied imidazole ketone erastin (IKE) and protocols for IKE administration to mice. ZNC and XJ supervised the research.
