WebAside from GSH and GPX4, the role of the Nrf2-HO-1 signaling pathway is the common inducible antioxidant defense system. The transcription factor Nrf2, a master regulator of the antioxidant system, also plays a critical role in mediating iron/metal metabolism, lipid metabolism, and glutathione synthesis, all of which involve in preventing the ...

And the expression of key proteins Nrf2, HO-1, NQO-1, and GCLC in the Nrf2/HO-1 antioxidant-related pathway was significantly upregulated.
WebApr 12, 2024 · However, some studies indicated that under ferroptosis conditions, the stability and activity of Nfe2l2 increased, which played an important role in preventing LPO and had an anti-ferroptosis role. 36 Nrf2 regulated the transcription of components of the GSH. 37 We speculated there was a compensatory transcriptional upregulation of Nfe2l2 … WebMar 1, 2024 · Mechanistically, GLY inhibited GSH biosynthesis via blocking the phosphorylation and nuclear translocation of Nrf2, which resulted in GSH depletion-induced hepatocyte ferroptosis. In a mouse model, GLY exposure triggered ferroptosis-induced liver damage, which can be rescued by pretreatment with Fer-1 or tBHQ (a specific agonist of …
WebJun 16, 2024 · In addition, inhibition of the antioxidant Nrf2/HO-1 pathway was observed in TIC, which may also lead to the overproduction of lethal lipid peroxides. Mechanistically, using streptavidin-biotin affinity pull-down assay and computational molecular docking, we unveiled that triptolide directly binds to SLC7A11 to inactivate SLC7A11/GPX4 signal axis.
WebOct 30, 2024 · GSTZ1 serves as a tumor suppressor in HCC. GSH depletion caused by GSTZ1 deficiency elevates oxidative stress, thus constitutively activating the NRF2 antioxidant response pathway and accelerating HCC progression.
