Ghrelin Gene Regulation and Appetite Effects Differ Between Rat Strains
Ghrelin gene expression in the stomach and feeding response to a ghrelin analog differed significantly between lean and obesity-prone rat strains, revealing genetic variation in ghrelin biology that may parallel human diversity.
Quick Facts
What This Study Found
Gastric ghrelin gene expression regulation and feeding response to ghrelin analog differed between lean (Fischer 344) and obesity-prone (Sprague-Dawley) rats, demonstrating genetic/strain variability in ghrelin biology.
