Pharmacological activation of NRF2 by dimethyl fumarate (DMF) effectively counteracted the F-53B-induced suppression of GPX4 and FTH1, thereby alleviating ferroptosis and the ensuing cardiotoxicity. Collectively, our findings reveal the synergistic impact of F-53B and DOX on cardiotoxicity and elucidate the underlying mechanism involving the NRF2-mediated anti-ferroptosis pathway.
Notably, co-administration of brusatol abolished these effects, findings that are consistent with and strongly associated with Nrf2 activation; however, this mechanistic inference is based on pharmacologic inhibition. Collectively, ESA confers robust vascular protection against HCD-induced aortic remodeling and early atherosclerosis-like changes, with these effects being strongly associated with Nrf2 activation.
Additionally, high expression of NOX2 subunit genes and SNAI1 associated with reduced metastasis-free survival. These findings imply that myeloid cell-derived ROS initiate partial EMT in breast cancer cells to promote dissemination and that strategies to target myeloid cell-derived ROS may be explored to limit metastasis.
Lycorine can directly bind to and inhibit DPP3, thereby blocking the Nrf2 signaling pathway and downregulating SLC7A11. This disruption of GSH metabolism leads to the accumulation of ROS and iron overload, ultimately inducing ferroptosis in CRC cells.

Inhibition of p38 partially restored cell viability and reduced apoptosis. RTA-408 suppresses HCC cell survival through a p38-dependent stress response associated with NRF2 activation and LC3B/p62 accumulation.
