Proteomic analysis of diabetic retinas

As a metabolic disease, diabetes often leads to health complications such as heart failure, nephropathy, neurological disorders, and vision loss. Diabetic retinopathy (DR) affects as many as 100 million people worldwide. The mechanism of DR is complex and known to impact both neural and vascular components in the retina. […] To date, more than 100 congenital disorders of glycosylation have been described. However, no studies have identified the retinal¬†O-linked glycoproteome in health or disease. With a critical need to expedite the discovery of PTMomics in diabetic retinas, we identified both global changes in protein levels and the retinal¬†O-glycoproteome of control and diabetic mice.
