Gene and proteomics analysis of mouse AAAs suggested the principal targets of miR-29 included numerous VSMC generated extracellular matrix proteins (Col1a1, Col3a1, Col5a1, and Eln) and matrix-degrading enzymes (MMP-2 and MMP-9) [89,101], which were also validated in human AAA tissues [89]. Here, ELN is linked to triple-A syndrome.
