Abstract

I collagen was investigated in myocardium of normotensive Wistar rats and spontaneous hypertensive rats with and without experimental diabetes. The Ca2+-induced mitochondrial permeability transition pore was assessed in mitochondria isolated from rat hearts. The contents of cardiotrophin-1, annexin V and type I collagen in spontaneous hypertensive rats with diabetes were higher compared with that detected in the groups of normotensive rats and rats with diabetes. The cardiac titin level was 27 % lower in animals with hypertension and diabetes compared to spontaneous hypertensive rats without diabetes. The changes of cardiotrophin-1, annexin V, titin and type I collagen expression were associated with higher sensitivity of mitochondrial pore to Ca2+ in myocardium of spontaneous hypertensive rats with diabetes.

Keywords: cardiotrophin-1, annexin V, titin, type I collagen,mitochondrial pore, myocardium, rats, hypertension, diabetesmellitus.
