Tenascin-X is a large extracellular matrix protein that is abundantly expressed in several connective tissues. A 140-kDa C-terminal fragment of tenascin-X is present in human serum. Complete deficiency of tenascin-X is associated with Ehlers-Danlos syndrome, and these patients show major connective tissue alterations in their skin, as well as blood vessel fragility. In this study, we investigated whether tenascin-X is present in normal human aorta and abdominal aortic aneurysm (AAA) tissues and whether an association exists between serum tenascin-X levels and AAA.
