In the context of STZ‐induced diabetes, doxorubicin (Dox)–induced cardiomyopathy, acute myocardial infarction (AMI), and D‐galactose (D‐gal) induced aging conditions, differences in Foxj2 mRNA levels were indeed observed between the myocardium of healthy control mice and those affected by the respective diseases (Figure 5E–H). Here, FOXJ2 is linked to myocardial infarction.
