Scientists say they have found a way to reverse ageing
Ageing is a natural process of the body, but humanity has long been looking for a secret recipe to restore youth. Appearance is not enough - organs and cells need to be renewed.
Scientists from Harvard Medical School have conducted an interesting study. They tried to find out why we age and whether there is a way to prevent it. The details were reported by New Atlas.
Studies were conducted on mice. Scientists tried to cause epigenetic "software malfunctions" that cause the symptoms of ageing. By "rebooting" the system, you can potentially extend your life expectancy.
Our genome has a complete blueprint of the DNA contained in every cell of our body. The epigenome carries an additional level of information. Scientists have shown that lifestyle, including diet and exercise, can change epigenetic expression over the years.
Epigenetic changes are usually associated with the rate of biological ageing. However, there is still no answer to the question of whether they cause the symptoms of ageing or are a symptom in themselves.
Harvard scientists have accelerated the process of DNA damage and repair in mice using the induced change of epigenome (ICE) procedure.
Thus, the role of the epigenome in aging was scientifically confirmed. The next step was to see if we could slow down this process. The team used a "gene therapy cocktail of three genes known as Oct4, Sox2 and Klf4".
The ICE mice experienced a sharp decline in biomarkers of ageing. Tissues and organs returned to a younger state.
"It's like rebooting a faulty computer," said David Sinclair, senior author of the study.
Harvard scientists are confident that this is a revolutionary discovery that will even help treat many diseases more effectively.
"This means that cancer, diabetes, and Alzheimer's may have the same underlying cause that can be eliminated with a single treatment," Sinclair wrote on Twitter.
