Experimental intervention with rapamycin reduces hepatic steatosis and inflammation in aging mice subjected to high-fat diet-induced stress, suggesting therapeutic potential.
Key Points
MAIN FINDING: Aging intensifies the liver's sensitivity to metabolic stress, worsening conditions like steatosis and inflammation.
KEY EVIDENCE: Older mice on a high-fat diet showed severe liver alterations, which rapamycin significantly reversed.
APPROACH: The study compared young and old mice's liver responses to a high-fat diet and analyzed changes in gene expression.
SIGNIFICANCE: These results indicate that rapamycin may be a promising treatment against age-related liver diseases and MAFLD progression.
