However, the effects of dual deficiency of ACE2 and Mas (ACE2/Mas) on Ang II‐induced hypertensive nephropathy remain unexplored, which was investigated in this study in a mouse model of hypertension induced in either ACE2 knockout (KO) or Mas KO mice and in double ACE2/Mas KO mice by subcutaneously chronic infusion of Ang II. This evidence concerns the gene MAS1 and hypertensive disorder.
