ABSTRACT
RATIONALE Yes-associated protein (YAP), the terminal effector of the Hippo signaling pathway, is crucial for regulating embryonic cardiomyocyte proliferation.

OBJECTIVE:

We hypothesized that YAP activation after myocardial infarction (MI) would preserve cardiac function and improve survival. METHODS AND

RESULTS:

We used a cardiac-specific, inducible expression system to activate YAP in adult mouse heart. Activation of YAP in adult heart promoted cardiomyocyte proliferation and did not deleteriously affect heart function. Furthermore, YAP activation after MI preserved heart function and reduced infarct size. Using adeno-associated virus subtype 9 (AAV9) as a delivery vector, we expressed human YAP (hYAP) in the adult murine myocardium immediately after MI. We found that AAV9hYAP significantly improved cardiac function and mouse survival. AAV9hYAP did not exert its salutary effects by reducing cardiomyocyte apoptosis. Rather, AAV9hYAP stimulated adult cardiomyocyte proliferation. Gene expression profiling indicated that AAV9hYAP stimulated expression of cell cycle genes and promoted a less mature cardiac gene expression signature.

CONCLUSIONS:

Cardiac-specific YAP activation after MI mitigated myocardial injury, improved cardiac function, and enhanced survival. These findings suggest that therapeutic activation of YAP or its downstream targets, potentially through AAV-mediated gene therapy, may be a strategy to improve outcome after MI.
