Abdominal aortic aneurysm (AAA) is an asymptomatic chronic disease of the aorta and its evolution is unpredictable. Despite the existence of a number of pathological mechanisms contributing to the dilation of the human AAA wall, there is currently no specific therapy to prevent the fatal rupture of the aorta. Our objective was to identify novel mediators and/or biomarkers involved in the instability of the aortic wall that could help to prevent AAA progression.
