چکیده

This review focuses on the emerging evidence that attenuation of the production of reactive oxygen species and inhibition of inflammatory pathways play a central role in the antiaging cardiovascular effects of caloric restriction. Particular emphasis is placed on the potential role of the plasma membrane redox system in caloric restriction–induced pathways responsible for sensing oxidative stress and increasing cellular oxidative stress resistance. We propose that caloric restriction increases bioavailability of NO, decreases vascular reactive oxygen species generation, activates the Nrf2/antioxidant response element pathway, inducing reactive oxygen species detoxification systems, exerts antiinflammatory effects, and, thereby, suppresses initiation/progression of vascular disease that accompany aging.

Telomere Biology and Cardiovascular Disease Vascular Cell Senescence: Contribution to Atherosclerosis Stem Cells and the Regeneration of the Aging Cardiovascular System Mechanisms of Cardiovascular Disease in Accelerated Aging Syndromes Mechanisms Underlying Caloric Restriction, Lipid Metabolism, and Life Span Regulation

It is well established that cardiovascular repair mechanisms become progressively impaired with age and that advanced age is itself a significant risk factor for cardiovascular disease. Although therapeutic developments have improved the prognosis for those with cardiovascular disease, mortality rates have nevertheless remained virtually unchanged in the last twenty years. Clearly, there is a n...

Cardiologists and most physicians believe that aging is an independent risk factor for human atherosclerosis, whereas atherosclerosis is thought to be a characteristic feature of aging in humans by many gerontologists. Because atherosclerosis is among the age-associated changes that almost always escape the influence of natural selection in humans, it might be reasonable to regard atheroscleros...

Accumulation of cellular damage with advancing age leads to atherothrombosis and associated cardiovascular disease. Ageing is also characterized by shortening of the DNA component of telomeres, the specialized genetic segments located at the end of eukaryotic chromosomes that protect them from end-to-end fusions. By inducing genomic instability, replicative senescence and apoptosis, shortening ...

Expanding the concept of telomere dysfunction in cardiovascular disease.

Cellular repair and regeneration are considered important features of cardiovascular homeostasis. Exhaustion of these processes and replicative senescence during aging may promote cardiovascular diseases.1 This concept has recently received support from studies that used telomere length as a marker of biological aging and predictor of replicative senescence.1 Further studies show that shorter t...

Vascular Aging and Diseases: Molecular Mechanisms and Influences

Vascular aging plays an important role in the mortality of the elderly, but vascular aging can be dependent on other factors such as diseases. Various diseases such as Alzheimer, diabetes, thalassemia, and other diseases affect the mechanisms of vascular aging. It will harm the recovery process of these patients. There are methods for measuring vascular aging such as instrumental measurements a...
