Selenoproteins are crucial for several biological functions, including the breakdown of harmful substances, immune system support, and regulating metabolic processes. However, in specific contexts, these proteins can be misused and shield cancer cells from death. One such protein, glutathione peroxidase 4 (GPX4), is vital in supporting cellular protection and cancer cell survival.
