Many epidemiological studies have indicated a protective role for a diet rich in fruits and vegetables against the development and progression of cardiovascular disease (CVD), one of the leading causes of morbidity and mortality worldwide. Physical inactivity and unhealthy eating contribute to these conditions. This article assesses the scientific rationale(More)
The structural and molecular diversity of vascular endothelium may depend on the functional state and tissue localisation of its cells. Tumour vasculature expresses a number of molecular markers that distinguish it from normal vasculature. In cancer, the determinant of specific tumour vasculature heterogeneity is, in part, dictated by dysregulated(More)
Increasing evidence indicates that mammalian SIRT1 mediates calorie restriction and influences lifespan regulating a number of biological molecules such as FoxO1. SIRT1 controls the angiogenic activity of endothelial cells via deacetylation of FoxO1. Endothelial dysfunction and reduced new blood vessel growth in diabetes involve a decreased bioactivity of(More)
The circulating form of endothelial progenitors cells (EPCs) are derived from bone marrow (BM)-derived hematopoietic stem cells (HSCs). Enhanced mobilization of EPCs was shown to be linked to cardiac diseases. This study investigated whether reduced EPC levels in advanced coronary heart disease (CHD) are secondary to a functional exhaustion of HSCs in the(More)
Cancer and vascular diseases remain the predominant causes of morbidity and mortality in industrialized countries worldwide. The course of atherosclerosis with initiation, progression, and complication parallels the three stages of carcinogenesis with induction, growth, and invasion of tissue and neoangiogenesis. Within this framework, the oncogene c-Myc(More)
Endothelial progenitor cell (EPC) therapy is a promising approach to promote angiogenesis and endothelial repair in patients with cardiovascular diseases (CVD). However, their release of proinflammatory mediators may compromise the therapeutic efficacy. Little is known about the role of Platelet-Activating Factor (PAF) in EPC functional response. Here, we(More)
Silent information regulator-2 (Sir-2) proteins, or sirtuins, are a highly conserved protein family of histone deacetylases that promote longevity by mediating many of the beneficial effects of calorie restriction which extends life span and reduces the incidence of cancer, cardiovascular disease (CVD), and diabetes. Here, we review the role of sirtuins(More)
Crucial advances in our understanding of basic pathogenic mechanisms involved in atherogenesis have been achieved during the past 2 decades. The historical hypothesis of pathogenesis (“lipid accumulation”) has evolved to integrate several causal events contributing to the initiation and evolution of atherosclerosis. Vascular inflammation and apoptosis may(More)
Continuing our investigations on plants belonging to the Asclepiadaceae family, three new cardenolide glycosides, 3'-O-beta-D-glucopyranosylcalactin (1), 12-dehydroxyghalakinoside (2), and 6'-dehydroxyghalakinoside (3), along with the known ghalakinoside (4) and calactin (5), were isolated from the roots of Pergularia tomentosa. The structures of these(More)
