Autonomic nervous system-mediated effects of galanin-like peptide on lipid metabolism in liver and adipose tissue

Abstract: Galanin-like peptide (GALP) is a neuropeptide involved in the regulation of feeding behavior and energy metabolism in mammals. While a weight loss effect of GALP has been reported, its effects on lipid metabolism have not been investigated. The aim of this study was to determine if GALP regulates lipid metabolism in liver and adipose tissue via an action on the sympathetic nervous system. The respiratory exchange ratio of mice administered GALP intracerebroventricularly was lower than that of saline-treated an… Show more

“…Adipose tissue and liver are the major organs involve in lipid metabolism in vivo [41,42]. So we harvested subcutaneous adipose tissue, which is more sensitive to extrinsic signal than visceral adipose tissue [37], and liver to investigate whether altered lipidemia is influenced by modulated lipid metabolism in peripheral organs.…”

“…Intranasally administered GALP resulted in a decreased cumulative body weight in DIO mice in spite of a decreased in locomotor activity. The respiratory quotient produced by centrally administered GALP has been reported to be 0.7, meaning that GALP metabolizes lipid 24 25 . Intracerebroventricularly administered GALP increased expression of hepatic fatty acid βoxidation-related genes (carnitine palmitoyltransferase -1, medium-chain acyl-CoA dehydrogenase and acyl-CoA oxidase (AOX)) in the liver of C57BL/6 mice 25 .…”

Intracerebroventricularly administered GALP increased expression of hepatic fatty acid βoxidation-related genes (carnitine palmitoyltransferase -1, medium-chain acyl-CoA dehydrogenase and acyl-CoA oxidase (AOX)) in the liver of C57BL/6 mice 25 . Therefore, these results suggest that intranasally administered GALP simultaneously suppresses energy intake and promotes energy expenditure without loss of sensitivity due to repeated exposure to GALP.…”
