25. Arginase 1 is crucially involved in Ang II-induced smooth muscle cell proliferation and arterial fibrosis and stiffness and represents a promising therapeutic target. PMID: 25807386
26. FoxO4 activates Arg1 transcription in endothelial cells in response to MI, leading to downregulation of nitric oxide and upregulation of neutrophil infiltration to the infarct area. PMID: 26438688
