Research Abstract

In this study, we examined the effects of nutrients on ghrelin secretion by original ghrelin secreting cell line, MGN3-1. Glucose showed no apparent effect on ghrelin secretion. Octanoic acid increased active-ghrelin secretion, while long-chain fatty acids suppressed it. Certain amino acids stimulated ghrelin secretion. These results indicate that nutrients have certain roles in regulation of ghrelin secretion.
