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.
Notably, combined treatment with the PRMT5 inhibitor GSK3326595 and DMF synergistically enhances anti-tumor activity in a patient-derived xenograft (PDX) model. These findings reveal a previously unrecognized PRMT5-ATF5-SLC7A11 axis that drives ferroptosis resistance in B-cell lymphomas and provide a strong rationale for targeting PRMT5 to potentiate ferroptosis-based therapies in relapsed or refractory disease.

In vivo, RRx-001 significantly inhibits tumor growth, enhances T-cell infiltration, promotes M1 macrophage polarization, downregulates PD-L1 expression, and strengthens anti-tumor immunity through T cell-related pathways. With both metabolic and immunomodulatory effects, RRx-001 provides a basis for novel HCC therapies, and future research could explore its synergistic effects with immune checkpoint inhibitors.

We found a p53-mediated downregulation of the Solute Carrier Family 7 Member 11 (SLC7A11)/Cystine/Glutamate Transporter (xCT) expression and glutathione levels. Our results suggest that combined administration of DMF and cisplatin, by targeting the dependency of cervical cancer cells on glutathione and (re)activating p53, represents a promising anticancer therapeutic strategy.
