Oridonin and Ferrostatin-1 Protocols

Oridonin (HPLC ≥98%) was purchased from Shanghai yuanye Bio-Technology Co., Ltd. (#B20310), then the drug was dissolved in DMSO and stored in − 20 °C for usage. Ferrostatin-1 (Fer-1) was purchased from MedChemExpress (#HY-100579, MCE), and stored in − 20 °C for usage. All primary antibody used in the experiments included Actin (1:10000, #60008–1-Ig, Proteintech), Bcl-2 (1:1000, #61193, Proteintech), BAX (1:5000, #50599–2-Ig, Proteintech), cl-caspase3 (1:10000, #19677–1-AP, Proteintech), Tublin (1:1000, #66031–1-Ig, Proteintech), GAPDH (1:2000, #CL594–60004, Proteintech), GPX4 (1:5000, #67763–1-IG, Proteintech), SLC7A11 (1:1000, #26864–1-AP, Proteintech), FTH1 (1:5000, #11682–1-AP, Proteintech), and ACSL4 (1:10000, #81196–1-RR, Proteintech), they were stored in − 20 °C for usage. Ferrostatin-1 (Fer-1) (#HY-100579, MCE), an effective ferroptosis inhibitor [32 (link)], was dissolved in dimethylsulfoxide (DMSO) to create stock solutions and stored at − 20 °C.
