Named the main cause of aging and age-related impotence
Scientists from the Karolinska Institute in Sweden revealed that muscle aging is due to accumulation of mutations in stem cells. According to the researchers, the scientific results will help to elaborate effective methods of struggle with age-related weakness. About it reported in a press release on MedicalXpress.
As they say the biologists, they found that each muscle stem cell to the 70-year-old age accumulated over thousands of mutations. Defects in DNA appear as a side effect of cell division, and at a young age there are mechanisms for the recovery of nucleic acids. The most protected are portions of chromosomes that are important for the functioning and survival of cells. Over time, however, protection is starting to fail.
The researchers plan to investigate whether exercise can slow down the pathological process. It is believed that physical activity contributes to the destruction of the damaged cells and self-renewal of muscle tissue.
In the journal Human Reproduction published an article by researchers from George Mason University that found that child birth is associated with accelerated aging women for 11 years.
