Posttranslational modulation of FoxO1 contributes to cardiac remodeling in post-ischemic heart failure

First, our results demonstrate that myocardial ischemia is associated with downregulation and posttranslational modification of cardiac FoxO1. Second, we show in a mouse model of postischemic heart failure that posttranslational modulation of FoxO1 alters heart function involving collagen and protein metabolism. Therefore, posttranslational modifications of FoxO1 could be an option to target remodeling processes in postischemic heart failure.
