|Title:||Effect of resveratrol on the biomarkers of oxidative stress and inflammation in monocyte cultures from PBMC’s of patients with myocardial infarction|
Mahdi, Abbas Ali
|Abstract:||Globally, one of the major causes of mortality and morbidity is ischemic heart disease (IHD). It has been established that in cardiac disorders, there exists a synergistic correlation between the oxidative stress and inflammatory cytokines. The stabilization and regulation of the oxidative stress and inflammatory cytokines in these patients is essential for the better management of the disease. Hence, the aim of this study was to study the effect of natural antioxidant, resveratrol, on the oxidative stress and inflammatory biomarkers in cultures of monocytes isolated from peripheral blood mononuclear cells (PBMCs) from the patients with myocardial infarction. Monocytes isolated from peripheral blood mononuclear cells (PBMC’s) of patients with myocardial infarction (MI) and healthy controls were employed in culture studies (with and without resveratrol). The 24 h cultures were subjected to evaluation of cytokine/ interleukins levels i.e. TNF-α, IL-1 and IL-6 as well as oxidative stress markers like MDA and Glutathione. The patient’s samples exhibited a significantly decreased level of intramonocyte glutathione as compared to samples of healthy subjects. On the other hand, significantly increased levels of MDA were observed in culture supernatants of monocytes isolated from PBMC’s of patients with MI in comparison to those of healthy controls. A significant degree of amelioration in intramonocyte glutathione levels coupled with decreased MDA levels (culture supernatants) were observed in cultures treated with resveratrol (20 ug/mL). Furthermore, 24 h culture supernatants of untreated patients cells exhibited augmented levels of IL-1, IL-6, and TNF-α. However, co-culturing with resveratrol exhibited a significant decrease in the levels of all the IL-1, IL-6 and TNF-α. Resveratrol—a potent polyphenol from grapes and also a natural antioxidant regulates the oxidative stress and inflammatory biomarkers and may be used as a prophylactic antioxidant in high risk patients.|
