ETS1 and diabetes mellitus: To examine the role of Ets1 in diabetes‐associated endothelial injury, mouse Ets1 overexpressing adeno‐associated virus‐9 genome particles containing the TIE promoter (AAV9‐m‐TIE‐Ets1‐Flag‐EGFP, abbreviated to AAV9‐Ets1) and control virus (AAV9‐NC) were injected via the tail vein into 8‐week‐old db/db or db/m mice.
