Figure 6. A scheme of the crosstalk between Hippo signaling and FoxO1.
In cardiomyocytes, YAP and FoxO1 form a functional complex that mediates catalase and MnSOD expression. In response to I/R, activation of the Hippo signaling cascade induces YAP inactivation, which leads to antioxidant gene suppression, ROS accumulation, and cell death.
