A study published in Circulation Research: Journal of the American Heart Association has revealed that people who have type 2 diabetes may have different blood levels of some ribonucleic acids (RNAs) than non-diabetic individuals.
Previous research has found an association between microRNAs and numerous diseases. The investigators assessed blood samples from a large population-based survey of various conditions, including diabetes. They discovered 13 microRNAs with distinct differences compared to those in participants without the disease.
"We think that some of these microRNA changes may precede the onset of diabetes," said researcher Manuel Mayr. "Future studies will need to confirm whether these new markers can help to actually target therapies and assess patients."
Five of the microRNAs in particular occurred before the onset of type 2 diabetes. One of these components is responsible for forming and regulating new blood vessels, and appeared to be one of the most frequent and reliable indicators of the condition.
Mayr added that the team hopes this new class of blood markers will give scientists more insight into the disease.
