Gap junction channels (GJCs), composed of connexins (Cxs) allow a direct intercellular communication that ensures the cardiac action potential (AP) propagation. Cx43 and Cx45 co-expressed in ventricular myocytes with changing expression levels and ratios in the healthy and the diseased heart ensure this function. The purpose of this study is to determine the contribution of Cx43 and Cx45 on the formation of GJCs and their electrical properties. Rat Liver Epithelial cells that endogenously express Cx43 and stably transfected to co-express accurate Cx43:Cx45 ratios have been used. The electrical properties of GJCs at each ratios were obtained by performing dual voltage clamp recordings on cell pairs. Expression of Cx45 decreases the electric...
