Matrix metalloproteinases (MMPs) and the tissue inhibitors of MMPs (TIMPs) have been recognized to play a pivotal role in matrix remodeling following myocardial infarction (MI). The aims of the present study were to examine the expression profile of MMPs/TIMP-1 after MI and to determine whether angiotensin II receptor (ATR) blockade improves MMPs/TIMP-1 balance. Compared with sham-operated rats, in vivo MI-induced a significant elevation of MMP-2, MMP-3 and MMP-9 levels and a marked reduction… CONTINUE READING
