Aging promotes a RAGE-dependent increase in breast cancer metastasis

Blocking a receptor linked to aging may reduce breast cancer spread in older patients, opening a new avenue for age-aware cancer treatment.

Aging drives breast cancer metastasis through RAGE receptor signaling in mouse models, mediated by increased S100A8/9 and AGE ligands in the aged tumor microenvironment; pharmacological inhibition of RAGE or S100A8/9 suppressed invasion. Elevated AGER expression in human BRCA correlates with poorer survival in older patients, identifying RAGE as a potential therapeutic target.

What the study was

Study design
Preclinical mouse model study with retrospective human correlate analysis
Population
Multiple mouse breast cancer models; human TCGA BRCA survival data for AGER expression correlates
Category
Drug Development
Maturity
Exploratory
Journal
Commun Biol

Why it surfaced

Mechanistically novel finding linking aging microenvironment to metastasis through RAGE. Human survival correlate strengthens translational relevance. RAGE inhibition as therapeutic strategy is actionable. Primarily preclinical — requires clinical follow-up.
