BACKGROUND: Gut hormones peptide YY (PYY) and glucagon-like peptide-1 (GLP-1) play an integral role in appetite control and energy homeostasis. Entero-endocrine L-cells can be stimulated by nutrients and or bile acids to co-secrete PYY and GLP-1. The aim of this study was to determine the response of bile acids, PYY, GLP-1 and ghrelin after a test meal. DESIGN: Twelve subjects with a BMI of 22·8 (0·52) kg/m² [mean (SEM)] received a 400 kcal test meal after which blood samples were taken every 30 min from 0 to 180 min. PYY, GLP-1 and ghrelin were measured by radioimmunoassays. Fractionated bile acids were measured by HPLC-MSMS. RESULTS: PYY positively correlated with glycochenodeoxycholic acid (GCDCA) (rs = 0·23, P = 0·03) and taurochenodeoxycholic acid (TCDCA) (rs = 0·26, P = 0·02). GLP-1 positively correlated with GCDCA (rs = 0·22, P = 0·047) and glycodeoxycholic acid (GDCA) (rs = 0·3, P = 0·005). Ghrelin negatively correlated with GDCA (rs = -0·45, P≤ 0·0001), TCDCA (rs = -0·23, P = 0·034) and taurodeoxycholic acid (TDCA) (rs = -0·44, P≤ 0·0001). CONCLUSION: PYY and GLP-1 responses correlated with chenodeoxycholic acid (CDCA) counterparts, whereas ghrelin negatively correlated with deoxycholic acid (DCA) counterparts. Specific bile acids may thus differentially affect entero-endocrine cells. |
