ATRA attenuates MMP2, MMP9, and AT1 protein expression in the abdominal aorta. a: ATRA induces RARα protein expression in the Control and ATRA groups. b, c, d: MMP2, MMP9, and AT1 expression was increased in the AAA group and significantly reduced in the ATRA group. Data are shown as the mean ± SD. ^*P < 0.05 vs. Sham and Control group, ^#P < 0.05 vs. AAA group, n = 5 per group
