The DDAHs association with FGF2 warrants further investigation as well, as DDAH2 has recently been shown to alleviate fibrosis associated with diabetic cardiomyopathy [38] and DDAH1 to inhibit the Wnt/β-catenin pathway, EMT, and gastric cancer cell migration [53]. The gene discussed is DDAH2; the disease is diabetic cardiomyopathy.
