Abstract: | All organisms end with their death, and many parts of cells die through intrinsic suicide machineries in response to diverse stimuli. These intrinsic cell death pathways are often termed as programmed cell deaths (PCDs), and are critical for organism development, tissue homeostasis and various diseases. Recent evidence has revealed that most of PCDs involve a tumor suppressor p53 and components of the intra-mitochondria. Furthermore, the movement and positioning of p53 in cells affect the induction of each PCD pathway. Here we provide a comprehensive review on p53-related PCD mechanisms via the mitochondria, namely classical apoptosis, non-classical apoptosis, autophagic cell death, ferroptosis, necroptosis. In addition, we discuss the roles of p53 in each PCD pathway by focusing its altered intracellular localization in response to diverse cellular stresses. |
