Oral vanadyl sulfate (VS) acts as a senolytic in male mice, extending lifespan and killing senescent cells by targeting a redox-proteostasis vulnerability.
- Why it matters: Diet-driven links to senescent cell accumulation and age-related disease are unclear, limiting senolytic strategies that could safely improve aging outcomes.
- What they did: The study used integrated functional omics to compare senescent versus nonsenescent cells, then tested VS in male mice and mechanistically examined glutathione disulfide (GSSG) and reactive cysteines.
- The result: Senescent cells showed globally reduced proteome cysteine reactivity with increased apparent cysteine reactivity of endoplasmic reticulum proteostasis proteins, linked to GSSG accumulation; VS inactivated reactive cysteines, promoted disulfide bond formation, triggered misfolding/aggregation, and cell death.
