Figure 6. Strategies of improving calcium handling and SR Ca-content in heart failure.
These strategies have focused pharmacologically on inhibiting the Na/K ATPase which results in increased intracellular Ca2+ and more recently on stabilizing the Ryanodine Receptor in resulting in decreased SR Ca2+ leak. Gene editing techniques have focused on enhancing SERCA2a’s activity by either increasing the level of SERCA2a or altering the expression of its partners.
