General description

Diabetes mellitus (DM) has become one of the main threats to human health in the 21st century. Our understanding of the DM is largely on the detrimental effects of hyperglycemia and hyperlipidemia, including its pathophysiological effects on cardiovascular, renal and nervous systems. In recent years, research on the pathogenesis of DM and its complications have been focused on AGE-RAGE elicited signals and their effects, increased fatty acid levels and insulin resistance, adipocytes and adipokines, increased ROS and inflammation in a systemic nature etc.. Thus, a systemic, in vivo approach to study the DM-inflicted metabolic disorders appeared to be appropriate. 

 

Background

Metabolic syndrome is a collection of multiple risk factors. Patients with metabolic syndrome are at twice risk for developing cardiovascular disease (CVD) and rise the risk about five times higher for type 2 diabetes mellitus (T2DM). Insulin resistance, dyslipidemia,oxidative stress, and inflammation are the key underlying mechanisms of metabolic syndrome. The contribution and interactions between these risk factors deserve great attention. 

 

Aims

As an emerging platform technology in the post-genomic era, metabolomics is aimed to study the global profiling and variations of low-molecular-weight metabolites caused by pathophysiological stimuli and genetic variations. Metabolomics is most useful for the study of human degenerative diseases, which involve multiple risk factors like metabolic syndrome and T2DM.

Methods

We propose a relatively more holistic approach, the metabonomics, to detect, quantify, and catalogue the time related metabolic processes, and to relate such processes to the trajectories of the pathophysiological events occurring in DM.
