Overview: This research project investigates targeting the PKG/Chip signaling nexus to attenuate transthyretin cardiac amyloidosis.

Significance: We identified a pathway that is uniquely reduced in transthyretin cardiac amyloidosis and we hope by stimulating PKG and Chip that we will improve upon current therapeutic strategies and the outcomes for cardiac amyloidosis patients.

Innovation: This program explores a novel mechanism to increase the degradation of transthyretin once it is taken up by the myocardium thereby reducing the burden on the heart while enhancing the function of the heart.

Impact: Increasing the removal of transthyretin in the heart is not achievable with current pharmacological strategies. Our study addresses this need by providing a new therapeutic approach to better treatment for cardiac amyloidosis patients.
