Autophagy has emerged as a potentially important factor in the pathogenesis of atherosclerosis. Dehydroepiandrosterone (DHEA) is an adrenal steroid of great recent interest due to its anti-aging and anti-atherogenic effects; however, little is known about its role in autophagy and endothelial senescence.The aim of this study was to investigate whether DHEA prevents linoleic acid (LA)-induced endothelial...
A β-galactosidase activity has recently been used as a histochemical marker of replicative senescence in human fibroblasts and keratinocytes. To establish whether this marker could be used to detect senescence of vascular cells, we have investigated its presence in cultures of serially passaged human umbilical vein endothelial cells and rabbit aortic smooth muscle cells. β-Galactosidase activity was...
