The mitochondrial DNA (mtDNA) release-STING axis represents a metabolic biomarker system that leverages mitochondrial dysfunction as the primary driver of senescence detection and therapeutic targeting. This mechanism centers on the observation that senescent cells exhibit profound mitochondrial network fragmentation, oxidative damage, and membrane permeabilization that precedes nuclear chromatin instability. During senescence initiation, mitochondrial quality control mechanisms become overwhelm
**Molecular Mechanism and Rationale**
The p16^INK4a-CCF axis represents a sophisticated temporal biomarker system that exploits the sequential molecular events occurring during cellular senescence initiation and maintenance. At the molecular level, this mechanism begins with the activation of the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene, which encodes p16^INK4a protein. Upon cellular stress, DNA damage, or oncogene activation, p16^INK4a expression increases dramatically, functioning a
