Abstract
<p>(a) Data represent mean ± SEM of leptin mRNA in 6-hourly serial biopsies. There was a significant effect of group (<i>p</i><0.05; 2-way repeated measures ANOVA), but not of time or time x group interaction. There were no significant (<i>p</i>>0.05; Bonferroni post-hoc test) pair wise differences in leptin mRNA expression between the subject groups. The light-dark conditions are indicated by the bars below the x-axis. Diamonds, solid red line = lean subjects (n = 8); squares, dashed blue line = obese non-diabetic subjects (n = 10); triangles, dotted black line = type 2 diabetic group (n = 7). The average leptin mRNA expression for each subject was significantly (<i>p</i><0.05) correlated with both (b) average plasma leptin concentrations and (c) subjects’ BMI. (d) The average plasma leptin concentration for each subject was significantly (<i>p</i><0.001) correlated with subjects’ BMI.</p
