Senomorphic agents suppress SASP by targeting NF-κB, mTOR, JAK/STAT and cGAS‑STING pathways

The Numbers

The abstract does not provide numeric outcomes, effect sizes, or p‑values. No sample size, dosage, or duration is reported for any intervention.

Context: What This Study Is

Lead author Kong and colleagues from the School of Pharmacy compiled a systematic review published in Experimental Gerontology (2026). The authors surveyed pre‑clinical and early‑phase clinical literature on senomorphic agents—compounds that modulate the senescence‑associated secretory phenotype (SASP) without killing senescent cells. Their analysis focused on three classes: repurposed metabolic drugs (e.g., metformin), natural product derivatives (e.g., urolithin A), and designed synthetic inhibitors (e.g., ruxolitinib). The review aimed to map how these agents intersect with four signaling hubs—NF‑κB, mTOR, JAK/STAT, and cGAS‑STING—that drive SASP production.

What This Result Means

By cataloguing mechanistic studies, the authors highlight that senomorphics can blunt chronic inflammation at its source. Inhibition of NF‑κB reduces transcription of pro‑inflammatory cytokines; mTOR suppression curtails metabolic signaling that fuels SASP protein synthesis; JAK/STAT blockade interferes with cytokine‑driven feedback loops; and dampening cGAS‑STING limits innate immune activation triggered by cytosolic DNA fragments. Collectively, these actions reshape the senescent microenvironment, preserving the cell’s potential tissue‑repair functions while limiting deleterious secretions.

Study Limitations

• The article is a narrative synthesis rather than a meta‑analysis, so quantitative aggregation of effect sizes is absent.


• Most cited evidence derives from cell culture or animal models; human data remain sparse.


• The review acknowledges a shortage of validated SASP biomarkers and targeted delivery platforms, which hampers translation.

Practical Application

It's too early to apply this to a personal protocol. Robust human trials, standardized SASP readouts, and proven tissue‑specific delivery methods are required before performance‑oriented recommendations can be made.
