Expression of enteroendocrine hormones in L cells. (a) Gastric inhibitory polypeptide (GIP) content in GFP‐positive (GFP[+]) cells and GFP‐negative (GFP[–]) cells from the upper small intestine (UI), lower small intestine (LI), and colon (n = 5). (b–f) GIP, peptide YY (PYY), secretin, cholecystokinin (CCK) and somatostatin messenger ribonucleic acid levels in GFP(+) and GFP(–) cells from the UI, LI, and colon (n = 5). Expression levels were normalized against the internal control, peptidylprolyl isomerase A (PPIA). *P < 0.05, **P < 0.01, ***P < 0.001. NS, not significant.
