Although its cardiovascular actions have been widely examined, little is known about GLP-1's effects on the rat coronary artery (RCA) or about the mechanisms underpinning these effects. Here, we report that GLP-1 inhibits depolarization- or thromboxane receptor agonist (U46619)-induced RCA contraction in a dosage-dependent manner. Vasorelaxation was attenuated by denuding the endothelium, L-NAME (nitric oxide synthase inhibitor), and glyburide (K<sub>ATP</sub> channel blocker) but was not affected by indomethacin (cyclooxygenase inhibitor), iberiotoxin [Ca<sup>2+</sup>-activated K<sup>+</sup> channel (K<sub>Ca</sub>) blocker], or 4-aminopyridine (K<sub>V</sub> channel blocker). Furthermore, GLP-1 increased outward K<sup>+</sup> currents by enhancing the K<sub>ATP</sub> channel in rat coronary arterial smooth muscle cells (RCASMCs). These results show that GLP-1 is an endothelial-dependent vasospasmolytic agent in the RCA and imply that the relaxant effect is regulated by enhancing K<sub>ATP</sub> rather than K<sub>V</sub> or K<sub>Ca</sub> currents in RCASMCs.</p>","PeriodicalId":8290,"journal":{"name":"Archives of internal medicine","volume":"151 9 1","pages":"1968785"},"PeriodicalIF":1.8,"publicationDate":"2019-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6854269/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75570403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
