Programmed cell death (PCD) is a fundamental biological process that ensures cellular homeostasis by eliminating cells that are no longer needed or are potentially harmful. Among various PCD mechanisms, apoptosis has historically been the most recognized; however, recent discoveries have introduced ferroptosis as a significant player in the landscape of cellular death pathways. Unlike apoptosis,
