Comparing 2 hypotheses side-by-side
## Molecular Mechanism and Rationale Ferroptosis represents a distinct form of regulated cell death characterized by iron-dependent lipid peroxidation and subsequent membrane damage, fundamentally different from apoptosis, necrosis, or autophagy. The central molecular mechanism revolves around the depletion of glutathione peroxidase 4 (GPX4), the sole enzyme capable of reducing phospholipid hydroperoxides directly within cellular membranes. GPX4 functions as a selenocysteine-containing enzyme t
## Mechanistic Overview SIRT1 (Sirtuin 1), a class III NAD+-dependent histone deacetylase, functions as a master metabolic sensor that couples cellular energy status to transcriptional programs governing longevity and stress resistance. In healthy microglia, SIRT1 maintains cellular homeostasis through deacetylation of key transcriptional regulators including PGC1α, p53, and FOXO transcription factors. During aging, declining NAD+ levels and oxidative stress lead to SIRT1 downregulation, trigge
