Propafenone promotes mitochondrial HMOX1 expression by activating JNK/JUN signal, induces iron accumulation and ROS eruption, works together with RSL3 to promote ferroptosis in melanoma, Similarly, the CDK4/6 inhibitor palbociclib enhances the efficacy of the ferroptosis inducer auranofin by inducing cell senescence and depleting glutathione (GSH) and NADPH, This suggests that metabolic interventions as a strategy to overcome melanoma heterogeneity (Fan et al., 2024). The gene discussed is HMOX1; the disease is melanoma.
