Targeting the Hippo pathway in heart repair.

The Hippo pathway is an evolutionarily and functionally conserved signalling pathway that controls organ size by regulating cell proliferation, apoptosis, and differentiation. Emerging evidence has shown that the Hippo pathway plays critical roles in cardiac development, homeostasis, disease, and regeneration. Targeting the Hippo pathway has tremendous potential as a therapeutic strategy for treating intractable cardiovascular diseases, such as heart failure. In this review, we summarize the function of the Hippo pathway in the heart. Particularly, we highlight the post-translational modification of Hippo pathway components, including the core kinases LATS1/2 and their downstream effectors YAP/TAZ, in different contexts, which has provided new insights and avenues in cardiac research.
