The metabolic basis of regulated cell death.

Cellular metabolism acts as a gatekeeper of regulated cell death, setting permissive versus restrictive states that bias cell fate across apoptosis and ferroptosis.

• Why it matters: RCD is often treated as genetically encoded signaling, but its final outcome depends on metabolic state, leaving a gap in how metabolism constrains death decisions.
• What they did: The work proposes a framework linking bioenergetic capacity, redox balance, lipid composition, and metal availability to RCD permissiveness, emphasizing organelle-resolved metabolism and inter-organelle communication.
• The result: Positioning RCD pathways along a metabolic continuum—from energy-dependent apoptosis to chemistry-driven ferroptosis—explains death-response plasticity and suggests metabolic reprogramming can redirect cell fate.
