Sestrin 3 protein could treat type 2 diabetes

Posted on November 5, 2014 by DiabetesDigest.com Staff in News

A small protein, Sestrin 3, has been identified as having a big role in reducing blood glucose and increasing insulin sensitivity.
Researchers at the Indiana University (IU) School of Medicine indicated in their report that Sestrin 3 could be important in regulating molecular pathways that control glucose production and insulin sensitivity in the liver.
Published online in Diabetes, the journal of the American Diabetes Association, the report suggests Sestrin 3 is a logical target for drug development for type 2 diabetes.
What is Sestrin 3?
Sestrin 3 is a protein that can suppress oxidative stress and regulate metabolic homeostasis, keeping the balance of high and low blood sugars.
To test its effects, researchers monitored blood glucose levels and insulin sensitivity among mice with Sestrin 3 and mice genetically engineered not to produce it.
The mice were fed either a diet with 18 per cent of its calories from fat or a high-fat diet with 60 per cent of calories from fat.
The mice without the Sestrin 3 protein had elevated fasting blood glucose levels, while insulin and glucose tolerance tested significantly better in the mice with Sestrin 3.
