It only worked in mice until now, but scientists report a discovery that could pave the way for ending the signs of aging in humans.
In the new study, researchers focused on the function of mitochondria, the power plants of cells. They produce 90 percent of the chemical energy that cells need to survive, according to the study.
When the study team triggered a mutation that causes mitochondrial dysfunction, the mice quickly developed wrinkles and lost hairs. 19659002] In just four weeks, the mice had gray hair, a lower hair density, moved slower and were apathetic, and all these changes are characteristic signs of aging. Skin wrinkles were observed between 4 and 8 weeks after the introduction of the mutation, and wrinkles were more pronounced in females than in males.
But when the mitochondrial function was restored by disabling the mutation, the mice regained smooth skin "As far as we know, this observation is unprecedented," said the study's author Keshav Singh, Professor of Genetics at the University of Alabama. in Birmingham, according to HealthDay News.
Animal research often does not produce the same results in humans. But the authors of the study believe that this discovery opens the door to more research.
"This model with mice should provide an unprecedented opportunity for the development of strategies for the development of preventive and therapeutic drugs to increase mitochondrial functions for the treatment of skin and hair pathology associated with aging and of other human diseases in which mitochondrial dysfunction plays an important role, "Singh said in a university press release.
The study appears in the journal's edition. July 20th of the magazine Cell Death and Disease
