DSPE-PEG-CeO2 inhibits tumor cell proliferation by inducing oxidative stress and cell death
SUMMARYCeO2 can consume intracellular reducing power, but its poor biocompatibility limits its application in tumor therapy. In this study, we designed and synthesized DSPE-PEG-CeO2, which is easy to enter cells, and showed that DSPE-PEG-CeO2 can induce the increase of ROS levels in tumor cells, thereby inducing tumor cell apoptosis and DNA damage. This suppresses the appearance and development of tumor cells. This provides a new idea for the application of inorganic nanomaterials.
