discovered that the activation of MasRs by AVE0991 and Ang‐(1–7) resulted in increased smooth muscle cells, along with decreased accumulation of macrophages, expression levels of Mcp‐1 and Tnf‐α, and activity and expression of Mmp‐2 and ‐9 in both Ang II‐treated models mouse AAA and human VSMCs.103. This evidence concerns the gene MMP2 and triple-A syndrome.
