Thoracic aortic aneurysms (TAAs) develop by a multifactorial process involving maladaptive signaling pathways that alter the aortic vascular environment. Transforming growth factor-beta (TGF-beta) has been implicated in regulating the structure and composition of the extracellular matrix by differential activation of various intracellular signaling pathways. However, whether and to what degree TGF-beta signaling contributes to TAA development remains unclear. Accordingly, the hypothesis that alterations in TGF-beta signaling occur during aneurysm formation was tested in a murine model of TAA.
