Thus, it is important to determine the factors that regulate coronary blood flow. Ca<jats:sup>2+<\/jats:sup>\u2010activated chloride channels contribute to the regulation of arterial tone; however, their role in coronary arteries is unknown. The aim of this study was to investigate the expression and function of the main molecular correlate of Ca<jats:sup>2+<\/jats:sup>\u2010activated chloride channels, TMEM16A, in rat coronary arteries.<\/jats:p><\/jats:sec><jats:sec><jats:title>Experimental Approach<\/jats:title><jats:p>We performed mRNA and protein analysis, electrophysiological studies of coronary artery myocytes, and functional studies of coronary artery contractility and coronary perfusion, using novel inhibitors of TMEM16A. Furthermore, we assessed whether any changes in expression and function occurred in coronary arteries from spontaneously hypertensive rats (SHRs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Key Results<\/jats:title><jats:p>TMEM16A was expressed in rat coronary arteries. The TMEM16A\u2010specific inhibitor, MONNA, hyperpolarised the membrane potential in U46619. MONNA, T16A<jats:sub>inh<\/jats:sub>\u2010A01, and Ani9 attenuated 5\u2010HT\/U46619\u2010induced contractions. MONNA and T16A<jats:sub>inh<\/jats:sub>\u2010A01 also increased coronary flow in Langendorff perfused rat heart preparations. TMEM16A mRNA was increased in coronary artery smooth muscle cells from SHRs, and U46619 and 5\u2010HT were more potent in arteries from SHRs than in those from normal Wistar rats.
