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.

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.
