However, the molecular mechanism of NRF2 on ferroptosis remains to be investigated in gastric cancer. In our study, NRF 2 was found to transcriptionally activate Aldo-keto reductase 1 member B1 (AKR1B1) expression in gastric cancer. AKR1B1 is involved in the regulation of lipid metabolism by removing the aldehyde group of glutathione. We found that AKR1B1 is highly expressed in gastric cancer and is associated with a poor prognosis of the patients. In vitro experiments found that AKR1B1 has the ability to promote the proliferation and invasion of gastric cancer cells. AKR1B1 inhibited RSL3-induced ferroptosis in gastric cancer by reducing reactive oxygen species accumulation and lipid peroxidation, as well as decreasing intracellular ferrous ion and malondialdehyde expression and increasing glutathione expression. Our study demonstrated that AKR1B1 resisted RSL3-induced ferroptosis by regulating GPX4, PTGS2 and ACSL4, which was further demonstrated in a xenograft nude mouse model.

A DNA Methylation-Specific PCR assay demonstrated that AGR2 upregulation resulted from hypomethylated AGR2 in teratoma cells.
