Overview

APOA4 infusion improves aging-related glucose homeostasis and reduces hepatic lipid accumulation in old mice, suggesting a potential therapeutic role in age-related metabolic decline.

Key Points

  • To evaluate the effects of Apolipoprotein A4 on hepatic lipid accumulation and glucose tolerance in aging.
  • Infusion of saline or APOA4 for 4 weeks in male mice
  • Assessment of hepatic fatty acid oxidation, lipid accumulation, and glucose tolerance
  • Comparison between young and old mice in response to APOA4 treatment
  • APOA4 infusion increased hepatic fatty acid oxidation in old mice, leading to reduced liver weight and lipid accumulation
  • Improved glucose tolerance was observed in old mice receiving APOA4 infusion, but not in young mice
