Endostatin, a carboxyl-terminal fragment of collagen XVIII, has been shown to regress tumors in mice. In this study, we have analyzed the mechanism of endostatin action on endothelial cells and nonendothelial cells. Endostatin treatment of cow pulmonary artery endothelial cells caused apoptosis, as demonstrated by three methods, annexin V-fluorescein isothiocyanate staining, caspase 3, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end-labeling assay. Moreover, addition of endostatin led to a marked reduction of the Bcl-2 and Bcl-XL anti-apoptotic protein, whereas Bax protein levels were unaffected. These effects were not seen in several nonendothelial cells. Collectively, these findings provide important mechanistic insight into endostatin action.
