Targeting the SMAD3/CISD2 axis suppresses bladder cancer progression by promoting ferroptosis in mesenchymal-like bladder cancer cells. (PubMed, Cell Death Dis)
However, mesenchymal-like bladder cancer cells exhibited heightened sensitivity to the ferroptosis inducer Erastin, showing more pronounced suppression of proliferation, elevated ROS, higher LPO and MDA levels, and reduced GSH, confirming their enhanced susceptibility to ferroptosis...In vivo experiments further demonstrated that targeting the Smad3/CISD2 axis significantly suppressed xenograft tumor growth and activated ferroptosis. In conclusion, this study elucidates a novel mechanism by which the Smad3/CISD2 axis dynamically regulates ferroptosis through redox homeostasis reprogramming during EMT, providing a potential therapeutic strategy for targeting the progression of MIBC.
