Ghrelin O-acyltransferase mRNA levels in lean and obese rats exposed to a control, fibre or high-fibre diet. Values are means, with their standard errors represented by vertical bars (n 8). * Mean values were significantly different from the control diet within the obese groups (P<0·05). LC (□), lean control; LF (
), lean fibre; LHF (■), lean high fibre; OC (
), obese control; OF (
), obese fibre; OHF (
), obese high fibre.
