METTL3-mediated m6A modification of EGR1 mRNA promotes T2DM vasculopathy.

Vascular endothelial dysfunction is one of the leading causes of developing vascular lesions in Type 2 diabetes mellitus (T2DM). In the development of vascular lesions, when endothelial cells are stimulated by hyperglycemia, inflammation and other external conditions, endothelial cell dysfunction will occur, which promotes endothelial cells to lose its typical phenotype and gain mesenchymal characteristics, with the occurrence of endothelial-to-mesenchymal transition (EndMT). At the same time promote endothelial cell proliferation and migration, induce vascular injury.
