Untargeted metabolomic analysis in non-fasted diabetic dogs by UHPLC-HRMS.


ABSTRACT: INTRODUCTION:We recently identified variances in serum metabolomic profiles between fasted diabetic and healthy dogs, some having similarities to those identified in human type 1 diabetes. OBJECTIVES:Compare untargeted metabolomic profiles in the non-fasted state. METHODS:Serum from non-fasted diabetic (n?=?6) and healthy control (n?=?6) dogs were analyzed by liquid chromatography-high resolution mass spectrometry. RESULTS:Clear clustering of metabolites between groups were observed, with multiple perturbations identified that were similar to those previously observed in fasted diabetic dogs. CONCLUSION:These findings further support the development of targeted assays capable of detecting metabolites that may be useful as biomarkers of canine diabetes.
