Rupture of an AAA is associated with high mortality rates, but the mechanisms underlying the initiation, expansion, and rupture of AAAs are not yet fully understood. We aimed to characterize the pathophysiology of AAAs and identify new genes associated with AAA initiation and progression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      This study used RNA sequencing data on 140 samples, becoming the largest RNA sequencing data set for differential expression studies of AAAs. We performed differential expression analyses and analyses of differential splicing between dilated and nondilated aortic tissue samples, and between AAAs of different diameters. We identified 3002 differentially expressed genes between AAAs and controls that were independent of ischemic time, 1425 of which were new. Additionally, 8 genes (\n                      <jats:italic>EXTL3<\/jats:italic>\n                      ,\n                      <jats:italic>ZFR<\/jats:italic>\n                      ,\n                      <jats:italic>DUSP8<\/jats:italic>\n                      ,\n                      <jats:italic>DISP1<\/jats:italic>\n                      ,\n                      <jats:italic>USP33<\/jats:italic>\n                      ,\n                      <jats:italic>VPS37C<\/jats:italic>\n                      ,\n                      <jats:italic>ZNF784<\/jats:italic>\n                      ,\n                      <jats:italic>RFX1<\/jats:italic>\n                      ) were differentially expressed between AAAs of varying diameters and between AAAs and control samples.
