Interaction Information:

Comment The diabetes phenotype reveals itself through high sugar concentrations and reduced concentrations of the glucogenic amino acids glycine, serine and alanine in diabetic mice when compared with the wild-type mice. This observation may be explained by an impaired uptake of glucose by insulin-resistant cells, which induces hepatic gluconeogenesis, a process that then consumes glucogenic amino acids to initiate the production of the glucose precursors pyruvate and 3-phosphoglycerate.

Comment The methylmalonyl carnitine (C3-DC-M) shows a significant increase. An explanation for the increase of this metabolite could be a ketosis induced in the diabetic mice because an increased glucose production at limited glucose use generally results in hyperglycemia. Besides C3-DC-M, plasma concentrations of three other short-chained acylcarnitines, namely hydroxyl propionylcarnitine [C3(OH)], pimeloylcarnitine (C7-DC), and butenoylcarnitine (C4:1), are also significantly increased in diabetic mice.

Comment Rosiglitazone treatment significantly reduces plasma concentrations of numerous acylcarnitines, in particular those of myristoyl- (C14), palmitoyl- (C16), and stearoylcarnitines (C18) with saturated side chains, and of hexadecenylcarnitine (C16:1), octadecenylcarnitine (C18:1), and octadecadienylcarnitine (C18:2) with unsaturated side chains, and this both in diabetic and in healthy mice. This observation agrees with the expected effect of rosiglitazone on reducing the concentrations of nonesterified fatty acids in individuals with type 2 diabetes because free long-chain fatty acids are metabolized to acylcarnitines when transported into mitochondria for beta-oxidation.
