{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nRecent studies have identified a pivotal role for a protein—here referred to as POTED—which is activated through proteolysis by caspase‐3 and related enzymes. Upon apoptotic stimulation, POTED (previously known in part as DFNA5) is cleaved at a specific linker region to liberate an N‐terminal fragment that possesses intrinsic pore‐forming activity. This fragment disrupts plasma membrane integrity, thereby converting caspase‐3–mediated apoptosis into a lytic, proinflammatory form of programmed cell death known as pyroptosis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nThe proteolytic activation of POTED represents a molecular switch that governs the progression from silent apoptotic disassembly to inflammatory secondary necrosis. In diverse experimental settings—including chemotherapy‐induced tissue responses, innate immune activation by cytosolic signals, and developmental differentiation—caspase‐3 not only executes cell demolition but also processes proteins like POTED to promote membrane permeabilization. This dual capacity has been implicated in the regulation of cell disassembly, synaptic remodeling, and even modulation of differentiation and survival pathways, underscoring its importance in maintaining tissue homeostasis."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "3", "end_ref": "16"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nBeyond its immediate role in cell‐intrinsic death pathways, the caspase‐mediated activation of POTED is emerging as a central event in a variety of pathological contexts. Multiple lines of evidence now indicate that the fine‐tuned regulation of POTED and related proteolytic events not only influences tumor responses and the development of genomic instability but also affects neurodegenerative processes, cardiac remodeling, diabetic organ dysfunction, and inflammatory lung injury. Such observations—from studies of chemotherapy‐induced dysregulation and synaptic pruning to experiments in ischemia, infection, and tissue remodeling—underscore the broad impact of POTED as a molecular effector whose pore‐forming activity helps determine whether a cell dies silently by apoptosis or in a manner that can trigger secondary inflammatory cascades."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "17", "end_ref": "43"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Yupeng Wang, Wenqing Gao, Xuyan Shi, et al.
