Abdominal Aortic Aneurysm in the ApoE Knockout Mouse: Time Course of Control vs. Angiotensin II. Mus musculus

Transcriptional profiling of suprarenal aorta from ApoE-/- mice (12-14 weeks old, C57BL/6J background) treated by subcutaneous pump with angiotensin II or saline for 7d, 14d and 28d. Includes Ang II-treated samples at 7d found to have dissected aneurysms. Goal was to examine gene expression in developing AAA in this model over time. Overall design: Two condition experiment, one suprarenal aorta per array. Saline vs. angiotensin II at 3 time points, with inclusion of 3 Ang II-treated dissected. Total 35 arrays: 6 saline 7d, 6 saline 14d, 5 saline 28d, 4 Ang II 7d, 5 Ang II 14d, 6 Ang II 28d, 3 Ang II-dissected 7d.
