mRNA expression levels of gastric ghrelin and leptin under different feeding conditions[27]. (A) Effects of 48 h of fasting and 5 h of refeeding on gastric ghrelin expression; (B) Effects of 48 h of fasting and 5 h of refeeding on gastric leptin expression. Ghrelin and leptin mRNA levels are expressed relative to β-actin mRNA levels. Data are presented as mean ± SE. n = 3-4/group. aP < 0.05; bP < 0.01.
