Circulating galanin and galanin like peptide concentrations are correlated with increased triglyceride concentration in obese patients

Plasma GAL and GALP concentration was significantly higher in obese subjects than healthy controls (P < 0.001). In addition, the positive correlations were found between: GAL and triglyceride (TG) concentrations (r = 0.636; P < 0.001), GALP and TG concentrations (r = 0.362; P = 0.020) in obese subjects. Conclusions: Our results indicated that obese individuals have higher plasma GAL and GALP concentrations and both peptide concentrations were positively correlative to TG concentrations in obese human. GAL and GALP concentrations may be taken as potential biomarkers to predict development of obesity.
