Metabolic signature shift in type 2 diabetes mellitus revealed by mass spectrometry-based metabolomics

Abstract

Objective: Metabolic profiling of small molecules offers a snapshot of physiological processes. To identify metabolic signatures associated with type 2 diabetes and impaired fasting glucose (IFG) beyond differences in glucose, we used mass spectrometry-based metabolic profiling. Research Design and Methods: Individuals attending an institutional health screen were enrolled. IFG (n = 24) was defined as fasting glucose (FG) of 6.1 to 6.9 mmol/L and 2-hour post glucose load
