Fig. 7 — Briefly, CA sensitizes ferroptosis by upregulating HERPUD1 in liver cancer cells. It was further analyzed that CA acts on MDM2 through HERPUD1, increases the ubiquitination of GSS, and then reduces the content of GSS to reduce the synthesis of GSH, thereby increasing the sensitivity of liver cancer cells to ferroptosis.
