FoxO1–Dio2 signaling axis governs cardiomyocyte thyroid hormone metabolism and hypertrophic growth

Disease stress-induced cardiac hypertrophy is a major mechanism of pathological cardiac remodeling. Here, the authors unveil a previously unrecognized role of a FoxO1–Dio2 signaling axis in maladaptive, afterload-induced cardiac hypertrophy and intracellular thyroid hormone homeostasis.
