ERK1/2 gene expression and hypomethylation of Alu and LINE1 elements in patients with type 2 diabetes with and without cataract: Impact of hyperglycemia-induced oxidative stress.

Aims: This study aimed to delineate the effect of hyperglycemia on the Alu/LINE-1 hypomethylation and in ERK1/2 genes expression in type 2 diabetes with and without cataract.

Methods: This study included 58 diabetic patients without cataracts, 50 diabetic patients with cataracts, and 36 healthy controls. After DNA extraction and bisulfite treatment, LINE-1 and Alu methylation levels were assessed using Real-time MSP.
