Impact of matrix metalloproteinase-8 gene variations on the risk of thoracic aortic dissection in a Chinese Han population.

ABSTRACT: The importance of matrix metalloproteinase 8 (MMP8) expression during the progression of thoracic aortic dissection (TAD) has been recently emphasized. Genetic variations that affect proteinase expression or activity might contribute to the pathogenesis of TAD. In this study, we investigated whether the MMP8 C-799T genotype is associated with TAD. The frequency distributions of the MMP8 C-799T polymorphism were determined by direct sequencing. Associations between the polymorphism and disease progression in TAD were investigated. The level of plasma and tissue MMP8 was measured by enzyme-linked immunosorbent assay and western blotting. The MMP8 C-799T polymorphism was significantly associated with susceptibility to disease progression in TAD patients (n = 152) than in controls (n = 147) (P
