Research Abstract

The goals of this project were 1) to clarify the role of developmental gene program in the protection of aortic walls against the hemodynamic and humoral stress, and 2) to establish the mouse model of acute aortic dissection. We identified tenascin C as a stress-activated molecular safeguard to reinforce the aortic walls, of which failure leads to the development of acute aortic dissection. We found that the expression pattern of tenascin C does not match with the distribution of the cell lineages during the development of the aorta in mouse embryos, suggesting that heterogeneity in the tenascin C expression pattern is determined by the distribution of aortic stress rather than the endogenous developmental gene program. As a second goal of this project, we established a mouse model of acute aortic dissection that recapitulates the phenotype of human disease by continuous infusion of beta-aminopropionitrile and angiotensin II.
