Pro-aging effects of chronic glucocorticoid signaling.

Chronic glucocorticoid signaling accelerates aging by disrupting cellular processes and promoting age-related diseases, with effects comparable to biological aging.

• Why it matters: Understanding how sustained glucocorticoid exposure influences aging is crucial because it underpins many age-related diseases and health decline, yet the mechanisms remain unclear.
• What they did: The study reviews how prolonged glucocorticoid signaling affects nutrient sensing, autophagy, mitochondrial function, and cellular senescence, highlighting the role of the GC-responsive protein ACBP/DBI.
• The result: Findings suggest that managing chronic glucocorticoid levels could slow aging processes and reduce the risk of associated diseases, informing potential therapeutic strategies.
