Statins (simvastatin, pitavastatin) vs Control
Design
Preclinical
Key result
Statins inhibited the Rac1/NF-κB pathway and significantly reduced the secretion of MMP-9, MCP-2, and CXCL5 in human abdominal aortic aneurysm tissues ex vivo.

Provides mechanistic support for statins in human AAA; leaves open translation to clinical progression.
Do statins inhibit inflammation-related pathways in human abdominal aortic aneurysm tissue?
Statins directly inhibit the Rac1/NF-κB pathway to suppress MMP-9 and chemokine secretion in human AAA tissue, providing a mechanistic basis for their potential to attenuate AAA progression.
Yoshimura et al. (2015) studied Abdominal aortic aneurysm. Statins (simvastatin, pitavastatin) was evaluated on Activation of NF-κB and secretion of MMP-9, MCP-2, and CXCL5. Statins inhibited the Rac1/NF-κB pathway and significantly reduced the secretion of MMP-9, MCP-2, and CXCL5 in human abdominal aortic aneurysm tissues ex vivo.
