Abstract
Schematic representation showing that 20 (S)-Rg3 improves mouse NASH. 20(S)-Rg3 reduces OxPLs levels and ameliorates ferroptosis in the liver of NASH mice. Mechanistically, 20(S)-Rg3 activates SPOP. Meanwhile, SPOP attenuates the ATF3-mediated transcriptional repression of NUPR1 by enhancing the K48-linked ubiquitination of ATF3. Upregulated NUPR1 rescues redox balance and reduces lipid peroxidation, ultimately inhibiting hepatocellular ferroptosis.
