2-aminoadipic acid (2-AAA) - a new biomarker which can help predict diabetes risk has been discovered by scientists.
Wang said that from the baseline blood samples, that they identified a novel biomarker, 2-aminoadipic acid (2-AAA), that was higher in people who went on to develop diabetes than in those who did not.
Individuals having 2-AAA concentrations in the top quartile had up to a fourfold risk of developing diabetes during the 12-year follow-up period compared with people in the lowest quartile.
The researchers also conducted laboratory studies to understand why this biomarker is elevated so well in advance of the onset of diabetes.
They found that giving 2-AAA to mice alters the way they metabolize glucose. These molecules seem to influence the function of the pancreas, which is responsible for making insulin, the hormone that tells the body to take up blood sugar.
The findings have been published in The Journal of Clinical Investigation.
