BACKGROUND Inflammation plays a key role in atherosclerosis. Sirt1 regulates transcription factors involved in inflammatory processes and blunts atherosclerosis in mice. However, its role in humans remains to be defined. This study was therefore designed to investigate the role of Sirt1 in the development of atherosclerosis. METHODS AND RESULTS 48 male(More)
OBJECTIVE To assess the effects of aging on arterial thrombus formation by comparing 2-year-old with 11-week-old C57Bl6 mice. METHODS AND RESULTS Aging is a major risk factor for cardiovascular disease. In humans, assessing the direct effects of aging on vascular homeostasis is difficult because it occurs in the presence of other risk factors. Arterial(More)
AIM Constitutive genetic deletion of the adaptor protein p66(Shc) was shown to protect from ischaemia/reperfusion injury. Here, we aimed at understanding the molecular mechanisms underlying this effect in stroke and studied p66(Shc) gene regulation in human ischaemic stroke. METHODS AND RESULTS Ischaemia/reperfusion brain injury was induced by performing(More)
In Alzheimer's disease (AD), cerebral arteries, in contrast to cerebral microvessels, show both cerebral amyloid angiopathy (CAA) -dependent and -independent vessel wall pathology. However, it remains unclear whether CAA-independent vessel wall pathology affects arterial function, thereby chronically reducing cerebral perfusion, and, if so, which mechanisms(More)
The mammalian ShcA adaptor protein p66Shc is a key regulator of mitochondrial reactive oxygen species (ROS) production and has previously been shown to mediate amyloid β (Aβ)-peptide-induced cytotoxicity in vitro. Moreover, p66Shc is involved in mammalian longevity and lifespan determination as revealed in the p66Shc knockout mice, which are characterized(More)
