Fold increase in aortic gene expression in TAA induction compared with reference control

	Time After TAA Induction
Gene	2 wk	4 wk	8 wk	16 wk
Mmp14	5.53*	1.30	1.38	1.07
Mmp2	4.80*	1.66*	1.58	1.40
Timp2	1.47	1.11	1.09	1.14

Quantitative real-time PCR was used to measure the fold gene expression of matrix metalloproteinase 14, matrix metalloproteinase 2, and tissue inhibitor of metalloproteinase 2 at each time point in thoracic aortic aneurysm (TAA) progression.

^*P < 0.05 vs. reference control.
