Hormesis, cell death and aging
Frequently, low doses of toxins and other stressors not only are harmless but also activate an adaptive stress response that raise the resistance of the organism against high doses of the same agent. This phenomenon, which is known as "hormesis", is best represented by ischemic preconditioning, the situation in which short ischemic episodes protect the brain and the heart against prolonged shor...
متن کاملAging, anti-aging, and hormesis.
As a result of almost 50 years of efforts in collecting descriptive data, biogerontologists are now able to construct general principles of aging and to explore possibilities of gerontomodulation. Most of the data indicate that aging is characterized by a stochastic accumulation of molecular damage and a progressive failure of maintenance and repair, and the genes involved in homeodynamic pathw...
متن کاملNutritional hormesis and aging.
Nutritional hormesis has the potential to serve as a pro-healthy aging intervention by reducing the susceptibility of the elderly to various chronic degenerative diseases and thereby extending human healthspan. Supportive evidence for nutritional hormesis arising from essential nutrients (vitamins and minerals), dietary pesticides (natural and synthetic), dioxin and other herbicides, and acryla...
متن کاملHormesis, cell death, and regenerative medicine for neurode-generative diseases.
Although the adult human brain has a small number of neural stem cells, they are insufficient to repair the damaged brain to achieve significant functional recovery for neurodegenerative diseases and stroke. Stem cell therapy, by either enhancing endogenous neurogenesis, or transplanting stem cells, has been regarded as a promising solution. However, the harsh environment of the diseased brain ...
متن کاملJoint aging and chondrocyte cell death.
Articular cartilage extracellular matrix and cell function change with age and are considered to be the most important factors in the development and progression of osteoarthritis. The multifaceted nature of joint disease indicates that the contribution of cell death can be an important factor at early and late stages of osteoarthritis. Therefore, the pharmacologic inhibition of cell death is l...
