Circular RNA expression profiles in human abdominal aortic aneurysm

We have employed circRNA microarray expression profiling as a discovery platform to identify the dysregulated circRNAs in human abdominal aortic aneurysm. In this study, full thickness abdominal aortic aneurysm (AAA) specimens were collected from 4 patients with AAA. Over the same period, abdominal aortic samples just below the aortic trunk from 4 heart-beating brain-dead organ donors were used as the controls.
