| Outline of Final Research Achievements |
Tumor bearing mice showed an increase in total ghrelin and corticosterone, and a decrease in leptin and adiponectin, and the ratio of acyl ghrelin to total ghrelin in blood, and an increase in atrophy-related gene expression in skeletal muscle. Intraperitoneal administration of acyl ghrelin attenuated inhibitory effects of lipopolysaccharide (LPS) on food intake in normal mice. α-klotho-deficient mice showed a shorter lifespan and a decrease in blood glucose and insulin levels. In micloglia cell, rikkunshito suppressed the elevation of proinflammatory cytokines caused by LPS. These observations indicate that potentiating ghrelin signaling may be useful for the treatment of terminal stages of cancer, inflammation and aging.
