心脏重塑是心脏在持续性压力、代谢等刺激下发生的适应性形态结构变化过程,其中病理性心脏重塑是心血管不良事件独立危险因素。新型降糖药物钠–葡萄糖协同转运蛋白-2 (sodium-glucose cotransporter 2, SGLT2)抑制剂除了能够降低容量...心脏重塑是心脏在持续性压力、代谢等刺激下发生的适应性形态结构变化过程,其中病理性心脏重塑是心血管不良事件独立危险因素。新型降糖药物钠–葡萄糖协同转运蛋白-2 (sodium-glucose cotransporter 2, SGLT2)抑制剂除了能够降低容量负荷、减少心血管死亡及住院风险外,还展现出改善心脏结构和功能、逆转心脏重构的潜力。本文旨在对SGLT2抑制剂在改善心脏重塑方面的研究进展进行综述。Cardiac remodeling, a process of adaptive morphological and structural alterations in the heart triggered by sustained stress, metabolic, and other stimuli, among which pathological cardiac remodeling serves as an independent predictor of adverse cardiovascular outcomes. Recently, novel hypoglycemic agents, specifically sodium-glucose cotransporter 2 (SGLT2) inhibitors, have emerged as potential therapeutics that not only alleviate volume overload but also reduce the risk of cardiovascular mortality and hospitalization. Additionally, these agents exhibit promising effects in improving cardiac structure and function, as well as reversing pathological cardiac remodeling. This article aims to comprehensively review the progress made in investigating the therapeutic benefits of SGLT2 inhibitors in ameliorating cardiac remodeling.展开更多
文摘目的本研究旨在建立一种实时荧光定量PCR方法,用于检测猕猴三磷酸腺苷结合盒转运蛋白G2(adenosine triphosphate-binding cassette transporter protein G2,ABCG2)mRNA的基因转录水平。方法使用NCBI上GenBank数据库猕猴(Macaca mulatta)的ABCG2核苷酸序列号NM_001032919.1及内参GAPDH核苷酸序列号NM_001195426.1,借助Primer premier 5.0软件设计PCR引物。提取猕猴新鲜肾组织的总RNA,并反转录合成cDNA。接着,利用PCR引物进行实时荧光定量PCR扩增,并根据反应体系中荧光的变化情况定量分析ABCG2的mRNA相对表达水平。结果PCR产物测序结果显示,扩增的ABCG2和GAPDH核苷酸序列与NCBI上猕猴的序列同源性分别为90.91%和91.14%。ABCG2和GAPDH的扩增效率均达到80%~120%,实时荧光定量PCR标准曲线的熔解曲线为单峰,R2接近1。结论本研究建立的检测猕猴ABCG2 mRNA实时荧光定量检测方法,为研究高尿酸血症的发病机制以及新药开发奠定基础。
