• Note (General): Geranylgeranylacetone (GGA) is a chaperon inducer that protects various types of cell and tissue against stress. We examined whether GGA modulated energy intake and expenditure under stressful conditions. After mice were untreated or treated orally with GGA (0.16 g per kg body weight per day) for 10 days, they were subjected to 2-h restraint stress once or once a day for 5 consecutive days. GGA administration did not affect corticosterone response to the stress. Restraint stress rapidly decreased plasma leptin levels in control mice. GGA significantly increased circulating leptin levels without changing food intake and prevented the stress-induced decline of circulating leptin. However GGA-treated mice significantly reduced food intake during the repeated stress, compared with control mice. GGA prevented the stress-induced decline of leptin mRNA and its protein levels in epidydimal adipose tissues. We also found that GGA decreased ghrelin mRNA expression in gastric mucosa before the stress, whereas GGA-treated mice recovered the ghrelin mRNA expression to the baseline level after the repeated stress. Leptin and ghrelin are now recognized as regulators of anxiety and depressive mood. Our results suggest that GGA may regulate food intake and relief stress-induced mood disturbance through regulating leptin and ghrelin secretions.
