    Effect of chronic training on HCN1, KCN2 and HCN4 protein expression determined by immunocytochemical techniques in sedentary and trained dog. Bar diagram on top left indicates that the relative density of dog cardiomyocytes with HCN4 immunolabelling obtained from the trained group (n=30 cells/6 dogs) is significantly increased compared to that measured in the sedentary group (n=30 cells/6 dogs). Original immunofluorescent images are shown on the left . Bottom panels indicate lack of effect of chronic training on the relative density of dog cardiomyocytes with HCN1 and <t>HCN2</t> immunolabelling (n=30 – 30 cells/6 – 6 dogs for sedentary and trained groups, respectively).
