Abstract
The transactivation of the epidermal growth factor (EGF) receptor appears to be an important central transduction mechanism in mediating diabetes-induced vascular dysfunction. Angiotensin-(1-7) [Ang-(1-7)] via its Mas receptor can prevent the development of hyperglycaemia-induced cardiovascular complications. Here, we investigated whether Ang-(1-7) can inhibit hyperglycaemia-induced EGF receptor transactivation and its classical signalling via ERK1/2 and p38 MAPK in vivo and in vitro.
