"[In addition, beta ARK enzyme activity assays were performed, and the levels of beta 1- and beta 2-receptors were determined by radioligand binding. beta ARK mRNA levels were increased almost threefold in both forms of heart failure, and beta ARK activity was enhanced. beta 1-Receptor mRNA levels and beta 1-receptor numbers were decreased by approximately 50% in both failing groups, whereas these levels were unaltered for beta 2-receptors.].
