Review: stress granules and RNA-binding proteins in cellular senescence
This review proposes that stress granules and their RNA-binding proteins act as context-dependent parts of inflammation-driven senescence, not as universal triggers of senescence onset. [1]
Automatic summary · not editorially reviewed
The key findings
The review describes senescence as a complex stress response with stable growth arrest, chromatin remodeling, altered proteostasis, metabolic adaptation, innate immune activation and a secretory phenotype. [1]
The review examines stress-granule-induced inflammation linked to the senescence-associated secretory phenotype, cGAS-STING, NF-κB signaling and interferon response. [1]
The authors propose a stage-resolved modular framework and conclude that stress granules and associated RNA-binding proteins are context-dependent components of inflammation-driven senescence, not universal inducers of senescence onset. [1]

Senescence and stress granules as stress responses
The review describes cellular senescence as a complex stress response with stable growth arrest plus chromatin remodeling, altered protein homeostasis, metabolic adaptation, innate immune activation and the senescence-associated secretory phenotype. Stress granules are described as dynamic, membraneless ribonucleoprotein condensates that form during translational stress and help sort, signal and recover mRNA. The authors state that how senescence and stress granules intersect remains poorly defined.

Proposed links to inflammation and RNA-binding proteins
The review focuses on stress-granule-induced inflammation linked to the senescence-associated secretory phenotype, activation of cGAS-STING, induction of NF-κB signaling and an interferon response. It discusses why different senescence inducers differ in generating canonical stress granules and why granule formation does not necessarily mean global translation stops. It also examines possible roles of granule-associated RNA-binding proteins such as G3BP1/2, TIA1/TIAR, CAPRIN1, USP10, HuR, the ZFP36 family, FXR1 and TDP-43, alongside methodological standards for identifying stress granules in senescence.

Stage-resolved framework and therapeutic outlook
The authors present a stage-resolved modular framework for context-dependent functions of granule-associated RNA-binding proteins across senescence progression and discuss therapeutic opportunities. Their overall conclusion is that these granules and proteins should be viewed as context-dependent components in inflammation-driven senescence rather than universal inducers of senescence onset. This is a review's proposal, not a validated model or treatment.
