The source of aging

While the search for the "source of youth" continues, the "source of aging" – an area of the brain called the hypothalamus – may have already been found.

Aging and carcinogenesis

Carcinogenesis is not called the disease of old age for nothing. It is painful to live up to 150 years, being a collection of all genetic diseases known to science – hardly anyone would want to live so long, but just as bad.

How does aging begin?

The discoveries made during the yeast experiments bring clarity to the cascade of events that make up the aging process and pave the way to understanding the impact on life expectancy, aging and age-related diseases has the interaction of genetics and environmental factors.

Cancer and aging: a mini-review

Old cells, on the one hand, act as tumor suppressors, and on the other hand, the specific metabolism of old cells can cause the malignancy of neighboring precancerous cells.

"Selfish" DNA will help to study the aging process

Roundworms have been found to have "selfish" mitochondrial DNA that causes premature aging of cells. These molecules are a promising model for studying human aging processes at the molecular and cellular level.

Telomeres and diseases (5)

Given that telomeres limit the limit of proliferative capabilities of cells, the mechanisms of their elongation are a very promising tool for regenerative medicine.

Telomeres and diseases (4)

Simple but attractive arguments concerning the relationship between telomere length and aging should today be viewed with a certain degree of skepticism as contradictory, simplistic and potentially dangerous.

Telomeres and diseases (3)

There is a lot of evidence that telomere shortening is associated with the development of cancer and may be a causal factor in the development of a number of oncological diseases.

Telomeres and diseases (2)

The classic "telomere disease" is congenital dyskeratosis, a rare hereditary disease characterized by defective bone marrow function. Most adult telomeropathies are the result of mutations that are more likely to be risk factors.

Telomeres and diseases (1)

The review examines the mechanisms of the development of diseases associated with telomere defects, the potential role of telomere elongation in the treatment of diseases, as well as in preventing the start of the aging process or its reversal.

Another secret of longevity of naked diggers

The exceptionally long lifespan of naked diggers may also be due to the peculiarities of cellular mechanisms for processing proteins damaged by free radicals.
