Research in model organisms has shown that reducing IIS pathway activity can lead to increased lifespan and enhanced resistance to various stresses. In ''C. elegans'', mutations that reduce the function of the daf-2 gene, which encodes an insulin/IGF-1 receptor, result in a significantly extended lifespan{{pmid|8020096}}. Similarly, in fruit flies, reduced IGF signaling is associated with increased lifespan{{pmid|12524541}}.

The implications of the IIS pathway in human aging are an area of active research. Variations in genes related to this pathway, such as the FOXO3 gene, have been associated with longevity in human populations{{pmid|18516045}}. However, the exact mechanisms and potential for therapeutic intervention in humans remain to be fully elucidated.

The Insulin/IGF-1 Signaling pathway is a cornerstone in the study of the molecular biology of aging. Its conservation across species and clear influence on lifespan and healthspan make it a critical target for aging research. Future studies and clinical trials are expected to further clarify its role in human aging and potential for therapeutic interventions.
