Exendin-4 attenuates ischemia-induced ventricular arrhythmias in rats.
BACKGROUND Glucagon-like peptide-1 and its receptor agonist-exendin-4 (Ex-4) have been shown to provide beneficial effects for cardiovascular diseases. This study investigated the effects of Ex-4 on ischemia-induced ventricular arrhythmias in rats. METHODS Anesthetized male rats were once treated with Ex-4 (5 μg/kg, i.v.) 1 h before ischemia in the absence and/or presence of 5-hydroxydecanoic...
متن کاملDiosgenin attenuates cardiac oxidative stress in streptozotocin- induced diabetic rat
Background and Objective: Chronic diabetes mellitus (DM) leads to cardiovascular dysfunction. Diosgenin is a natural steroidal saponin with cardiovascular protective potential. In this research study, the beneficial effect of diosgenin was evaluated on some markers of oxidative stress in cardia tissue of streptozotocin (STZ)-diabetic rats. Materials and Methods: Male Wistar rats (n = 28) were ...
متن کاملSuppression of ROS Production by Exendin-4 in PSC Attenuates the High Glucose-Induced Islet Fibrosis
Pancreatic stellate cells (PSCs) play a major role to fibrotic islet destruction observed in diabetic patients and animal model of diabetes. Exendin-4 (Ex-4) is a potent insulinotropic agent and has been approved for the treatment of type 2 diabetes. However, there have been no reports demonstrating the effects of Ex-4 on pancreatic islet fibrosis. In this study, Ex-4 treatment clearly attenuat...
متن کاملExendin-4 attenuates high glucose-induced cardiomyocyte apoptosis via inhibition of endoplasmic reticulum stress and activation of SERCA2a.
Hyperglycemia-induced cardiomyocyte apoptosis contributes to diabetic cardiomyopathy. Glucagon-like peptide-1 (Glp1) receptor (Glp1r) agonists improve cardiac function and survival in response to ischemia-reperfusion and myocardial infarction. The present studies assessed whether Glp1r activation exerts direct cardioprotective effects in response to hyperglycemia. Treatment with the Glp1r agoni...
متن کاملBMP-7 attenuates adverse cardiac remodeling mediated through M2 macrophages in prediabetic cardiomyopathy.
The main objective of this study was to determine whether or not monocyte infiltration occurs in the prediabetic (PD) heart and its role in PD cardiomyopathy. We hypothesized that the PD heart is significantly populated with monocytes and that bone morphogenetic protein (BMP)-7, a novel mediator of monocyte polarization, activates infiltrated monocytes into anti-inflammatory M2 macrophages, the...
