Nr4a1 is the only gene which was regulated both in the brain and in the heart: almost 2-fold decreased in the prefrontal cortex and 5-fold increased in left ventricular myocardium of mice with CHF, which is not surprising as far as macrophages are well known to play a relevant role in remodeling after myocardial infarction (Hamid et al., 2009; Ismahil et al., 2013). Here, NR4A1 is linked to myocardial infarction.
