To evaluate the role of BAF60c in VSMCs in AAA development, we generated VSMC-specific Baf60c-KO mice (Baf60cSMKO) by crossbreeding Baf60c floxed mice (Baf60cfl/fl) with Myh11-CreERT2 mice; this was followed by tamoxifen induction (Supplemental Figure 2A). Here, SMARCD3 is linked to triple-A syndrome.
