In patients with pathological cardiac hypertrophy suffering from aortic stenosis or hypertrophic cardiomyopathy, we observed a significant up-regulation of common DPF3a and HEY targets, such as GATA4, FOXO1, SMAD7 and TBX3. These genes play well-known roles in cardiac development and disease (47–50). The gene discussed is GATA4; the disease is hypertrophic cardiomyopathy.
