|abstract=Vascular cell senescence, induced by the DNA damage response or inflammatory stress, contributes to age-associated vascular disease. Using complementary DNA microarray technology, we found that the level of POZ/BTB and AT-hook-containing zinc finger protein 1 ([[PATZ1]]) is downregulated during endothelial cell (EC) senescence. [[PATZ1]] may have an important role as a transcriptional repressor in chromatin remodeling and transcription regulation; however, the role of [[PATZ1]] in EC senescence and vascular aging remains unidentified. Knockdown of [[PATZ1]] in young cells accelerated premature EC senescence, which was confirmed by growth arrest, increased p53 protein level and senescence-associated β-galactosidase (SA-β-gal) activity, and repression of EC tube formation. In contrast, overexpression of [[PATZ1]] in senescent cells reversed senescent phenotypes. Cellular senescence induced by [[PATZ1]] knockdown in young cells was rescued by knockdown of p53, but not by knockdown of p16(INK4a). [[PATZ1]] knockdown increased ROS levels, and pretreatment with N-acetylcysteine abolished EC senescence induced by [[PATZ1]] knockdown. Notably, [[PATZ1]] immunoreactivity was lower in ECs of atherosclerotic tissues than those of normal arteries in LDLR(-/-) mice, and immunoreactivity also decreased in ECs of old human arteries. These results suggest that [[PATZ1]] may have an important role in the regulation of EC senescence through an ROS-mediated p53-dependent pathway and contribute to vascular diseases associated with aging.
