Time-dependent changes in the plasma amino acid concentration in diabetes mellitus.

ABSTRACT

We investigated longitudinal change in the amino acid (AA) profile in type 1 diabetes mellitus (DM) using AKITA mice, which develop DM as a result of insulin deficiency. The plasma concentrations of valine, leucine, isoleucine, as well as the total branched chain amino acids, alanine, citrulline and proline, were significantly higher in the diabetic mice. We show that the degree and timing of the changes were different among the plasma amino acid concentrations (pAAs) during the development of type 1 DM.
