Background: Long term exposure of INS-1 beta cells to elevated glucose concentrations has been observed to impair insulin expression, a phenomenon termed as glucose toxicity. Despite its potential relevance in the progression of diabetes, the underlying mechanisms is not yet fully understood.Aim: Target analysis of single, or a sub-group of metabolites has until now been the method of choice in mammalian cells to investigate the pathological state in ter...

Introduction: Insulin resistance (IR), a pathological state of low sensitivity to insulin in humans and animlas, is closely associated with type 2 diabetes mellitus, obesity and cardiovasculare dieseas. IR can be quantified using detailed protocols, such as the euglycemic-hyperinsulinemic clamp (EC) technique and the intravenous glucose tolerance test, or based on indices derived from the oral glucose tolerance test. Although these indices showed greater association with the i...
