Simvastatin Attenuates Abdominal Aortic Aneurysm Formation Favoured by Lack of Nrf2 Transcriptional Activity

Figure 5

Simvastatin mitigates AngII-induced changes in collagen and elastin status. Mice of both genotypes represent the following groups: (1) sham (saline, ), (2) angiotensin II (AngII group, ), (3) simvastatin+saline (Sim group, ), and (4) simvastatin+angiotensin II (Sim+AngII group, ). Simvastatin was administered daily for 7 consecutive days before osmotic pump placement and during AngII infusion for another consecutive 14 days.
