One of the main roles played by genes
“Wear and tear” of the body – not the worst thing for a person. An international group of scientists said that people grow old and die because of serious bad changes that are associated with the process of recycling cells own components (autophagy).
Researchers from University College London and Queen Mary College found that aging in roundworms occurs because of a work unwanted genes. The researchers came to the conclusion that the same mechanism is present in humans. About this writes the British scientific media reports znaj.ua.
According to experts, the biological processes that are the norm for a young developing organism, continue to occur at a later age, disrupting the homeostasis of the organism. As a result, diseases such as dementia, cancer, disorders of the cardiovascular system and chronic obstructive pulmonary disease.
The researchers analyzed signs of aging in the nematode Caenorhabditis elegans, laboratory strains which live 2-3 weeks. It turned out that one of the main roles played by genes that encode proteins involved in the process of autophagy.
