An iron-containing ferritin-based nanosensitizer for synergistic ferroptosis/sono-photodynamic cancer therapy

Abstract

with DHA and by simultaneously irradiation of FCD with both light and ultrasound. More importantly, the depletion of GSH by FCD could decrease glutathione peroxidase 4 (GPX4) and increase lipid peroxidation (LPO) levels, thereby inducing ferroptosis. Therefore, by integrating the advantageous GSH-depletion capacity, ROS generation ability, and ferroptosis induction capability into one single nanosystem, FCD can serve as a promising platform for combined chemo-sono-photodynamic therapy of cancer.
