Review: how actin cytoskeleton organization changes with aging
This review describes evidence across model organisms that aging is accompanied by progressive actin disorganization, and discusses how actin-regulating layers change with aging and may link to aging hallmarks and age-associated diseases. [1]
Automatic summary · not editorially reviewed
The key findings
The review synthesizes how actin integrity is maintained through chaperone networks, actin-binding proteins, transcriptional programs and post-translational modifications, and how these layers change during aging. [1]
Evidence across model organisms indicates that aging is accompanied by progressive actin disorganization, which can manifest as filament disassembly, aggregation and mislocalization. [1]
Recent studies suggest that targeted modulation of actin regulatory pathways might preserve cellular resilience and healthspan, while challenges in therapeutically targeting this system are emphasized. [1]

Review scope: actin maintenance and aging
The authors state that actin dynamics and organization have been studied extensively in development and some disease contexts, but the role of the actin cytoskeleton in aging has only recently begun to be considered. In this Review, they synthesize current understanding of how actin integrity is maintained through chaperone networks, actin-binding proteins, transcriptional programs and post-translational modifications, and how these regulatory layers change during aging.

Model-organism evidence of actin disorganization
According to the abstract, accumulating evidence across model organisms indicates that aging is accompanied by progressive actin disorganization. This can manifest as filament disassembly, aggregation and mislocalization, impacting cellular homeostasis. The review then describes how these changes emerge as links between cytoskeletal decline and core aging hallmarks, including loss of proteostasis, mitochondrial dysfunction and cellular senescence, and how this actin-related cellular dysregulation contributes to age-associated diseases such as neurodegeneration, cancer and muscle degeneration.

Possible modulation of actin pathways and open challenges
The abstract states that recent studies suggest targeted modulation of actin regulatory pathways might preserve cellular resilience and healthspan. It also emphasizes the challenges and opportunities in therapeutically targeting such a fundamental cellular system. These are described as suggestions from recent studies, not as established treatments or demonstrated benefits for human health.

How to interpret this
This explainer is based only on the abstract; the full text was not reviewed. The abstract reports a review of evidence, largely from model organisms, and does not provide study designs, sample sizes, follow-up or effect sizes. The suggested modulation of actin pathways is not established as a treatment or as a human health benefit.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
