Empagliflozin (empa), a selective sodium–glucose cotransporter (SGLT)2 inhibitor, reduced cardiovascular mortality and hospitalization for heart failure in patients with type 2 diabetes at high cardiovascular risk independent of glycemic control. The cardiovascular protective effect of empa was evaluated in an experimental model of metabolic syndrome, the obese ZSF1 rat, and its’ lean control. Lean and obese ZSF1 rats were either non-treated or treated with empa (30 mg/kg/day) for 6 weeks. Vascular reactivity was assessed using mesenteric artery rings, systolic blood pressure by tail-cuff sphygmomanometry, heart function and structural changes by echocardiography, and protein expression levels by Western blot analysis. Empa treatment reduced blood glucose levels from 275 to 196 mg/dl in obese ZSF1 rats whereas normoglycemia (134 mg/dl) was present in control lean ZSF1 rats and was unaffected by empa. Obese ZSF1 rats showed increased systolic blood pressure, and blunted endothelium-dependent relaxations associated with the appearance of endothelium-dependent contractile responses (EDCFs) compared to control lean rats. These effects were prevented by the empa treatment. Obese ZSF1 rats showed increased weight of the heart and of the left ventricle volume without the presence of diastolic or systolic dysfunction, which were improved by the empa treatment. An increased expression level of senescence markers (p53, p21, p16), tissue factor, VCAM-1, SGLT1 and SGLT2 and a down-regulation of eNOS were observed in the aortic inner curvature compared to the outer one in the control lean rats, which were prevented by the empa treatment. In the obese ZSF1 rats, no such effects were observed. The empa treatment reduced the increased body weight and weight of lungs, spleen, liver and perirenal fat, hyperglycemia and the increased levels of total cholesterol and triglycerides in obese ZSF1 rats, and increased blood ketone levels and urinary glucose excretion in control lean and obese ZSF1 rats. Empa reduced glucose levels by 28% and improved both endothelial function and cardiac remodeling in the obese ZSF1 rat. Empa also reduced the increased expression level of senescence, and atherothrombotic markers at arterial sites at risk in the control lean, but not obese, ZSF1 rat.

依帕列净改善代谢综合征ZSF1大鼠的收缩压,内皮功能障碍和心脏重塑。

Empagliflozin(empa)是一种选择性的钠-葡萄糖共转运蛋白(SGLT)2抑制剂,可降低具有高心血管风险的2型糖尿病患者的心血管疾病死亡率和因心力衰竭而住院,而不受血糖控制。在代谢综合征,肥胖的ZSF1大鼠及其瘦身控制的实验模型中评估了Empa的心血管保护作用。肥胖和肥胖的ZSF1大鼠未经治疗或以Empa(30 mg / kg /天)治疗6周。使用肠系膜动脉环评估血管反应性,通过尾袖血压计评估收缩压,通过超声心动图评估心脏功能和结构变化,并通过蛋白质印迹分析评估蛋白质表达水平。Empa处理可将肥胖ZSF1大鼠的血糖水平从275毫克/分升降低至196 mg / dl,而对照组瘦ZSF1大鼠存在正常血糖(134 mg / dl),不受empa的影响。与对照瘦鼠相比,肥胖的ZSF1大鼠显示收缩压升高,内皮依赖性松弛与内皮依赖性收缩反应(EDCF)出现有关。这些效果被Empa治疗所阻止。肥胖的ZSF1大鼠显示出心脏重量增加和左心室容积增加,而没有舒张功能或收缩功能障碍,这通过empa治疗得以改善。衰老标记(p53,p21,p16),组织因子,VCAM-1,在对照组瘦大鼠中,主动脉内曲度与外曲度相比,在主动脉内曲度中观察到SGLT1和SGLT2的下降以及eNOS的下调,这通过empa治疗得以预防。在肥胖的ZSF1大鼠中,未观察到这种作用。Empa治疗减少了肥胖的ZSF1大鼠的体重和肺,脾,肝和肾周围脂肪的增重,高血糖症以及总胆固醇和甘油三酸酯的水平增加,而对照瘦肉和肥胖ZSF1的血酮水平和尿葡萄糖排泄增加了大鼠。Empa使肥胖的ZSF1大鼠的葡萄糖水平降低了28%,并改善了内皮功能和心脏重塑。Empa还降低了对照组和瘦型ZSF1大鼠(但非肥胖)中处于危险中的动脉部位的衰老表达水平和动脉粥样硬化血栓形成标记的升高。这是由Empa治疗阻止的。在肥胖的ZSF1大鼠中,未观察到这种作用。Empa治疗减少了肥胖的ZSF1大鼠的体重和肺,脾,肝和肾周围脂肪的增重,高血糖症以及总胆固醇和甘油三酸酯的水平增加,而对照瘦肉和肥胖ZSF1的血酮水平和尿葡萄糖排泄增加了大鼠。Empa使肥胖的ZSF1大鼠的葡萄糖水平降低了28%,并改善了内皮功能和心脏重塑。Empa还降低了对照组和瘦型ZSF1大鼠(但非肥胖)中处于危险中的动脉部位的衰老表达水平和动脉粥样硬化血栓形成标记的升高。这是由Empa治疗阻止的。在肥胖的ZSF1大鼠中,未观察到这种作用。Empa治疗减少了肥胖ZSF1大鼠的体重和肺,脾,肝和肾周围脂肪的增重,高血糖症以及总胆固醇和甘油三酸酯的水平增加,而对照瘦肉和肥胖ZSF1的血酮水平和尿葡萄糖排泄增加了大鼠。Empa使肥胖的ZSF1大鼠的葡萄糖水平降低了28%,并改善了内皮功能和心脏重塑。Empa还降低了对照组和瘦型ZSF1大鼠(但非肥胖)中处于危险中的动脉部位的衰老表达水平和动脉粥样硬化血栓形成标记的升高。肥胖的ZSF1大鼠的脾脏,肝和肾周围脂肪,高血糖症和总胆固醇和甘油三酸酯的水平增加,而对照瘦和肥胖的ZSF1大鼠的血酮水平和尿葡萄糖排泄增加。Empa使肥胖的ZSF1大鼠的葡萄糖水平降低了28%,并改善了内皮功能和心脏重塑。Empa还降低了对照组和瘦型ZSF1大鼠(但非肥胖)中处于危险中的动脉部位的衰老表达水平和动脉粥样硬化血栓形成标记的升高。肥胖的ZSF1大鼠的脾脏,肝和肾周围脂肪,高血糖症和总胆固醇和甘油三酸酯的水平增加,而对照瘦和肥胖的ZSF1大鼠的血酮水平和尿葡萄糖排泄增加。Empa使肥胖的ZSF1大鼠的葡萄糖水平降低了28%,并改善了内皮功能和心脏重塑。Empa还降低了对照组和瘦型ZSF1肥胖大鼠的衰老和动脉粥样硬化血栓形成标志物的表达水平,而这些部位处于危险之中。Empa使肥胖的ZSF1大鼠的葡萄糖水平降低了28%,并改善了内皮功能和心脏重塑。Empa还降低了对照组和瘦型ZSF1大鼠(但非肥胖)中处于危险中的动脉部位的衰老表达水平和动脉粥样硬化血栓形成标记的升高。Empa使肥胖的ZSF1大鼠的葡萄糖水平降低了28%,并改善了内皮功能和心脏重塑。Empa还降低了对照组和瘦型ZSF1大鼠(但非肥胖)中处于危险中的动脉部位的衰老表达水平和动脉粥样硬化血栓形成标记的升高。
