Folic acid (FA) is a modulator of endothelial nitric oxide (NO) synthase (eNOS), which in turn is an important player in diseases associated with NO insufficiency or NOS dysregulation, such as pressure overload and myocardial infarction.
These results suggested that SSG might be used as a novel antithrombotic therapeutic agents in post-myocardial infarction and also, indicated that SSG exerts anti-inflammatory effects related to the inhibition of neutrophil functions and of NO and PGE2 production, which could be due to a decreased expression of iNOS and COX-2.
The expression of TNF-alpha and iNOS genes with the concomitant occurrence of a decrease in VEGF(120), VEGF(188) and VEGF(164) protein could be related to insufficient angiogenesis and may suggest the possible involvement of these events in remodeling after myocardial infarction.
