(Submitter supplied) Previous studies showed that aging in coronary arteries is associated with pro-inflammatory phenotypic changes and decreased NO bioavailability, which, we hypothesized, promotes vascular disease by inducing endothelial apoptosis. To test this hypothesis we characterized pro-apoptotic alterations in the phenotype of coronary arteries of aged (26 month old) and young (3 month old) F344 rats. DNA fragmentation analysis and TUNEL assay showed that in aged vessels there was a ~4 fold increase in the number of apoptotic endothelial cells. more...
