U.S. study says gene therapy can turn skin back to old age

scientists in the United States have made lab rats' skin "back to age" for two weeksHoward Zhang of Stanford University School of Medicine in California led the studyThe team bred a genetically modified laboratory mice with a defectgene that can be turned offWhen a special cream is applied to the skin of the laboratory mice, the skin cells stop aging"We made the mouse react to a cream containing a special chemical, and then applied the cream to only half of its skin, so the other half of its skin was still aging, " Zhang said"The results showed that after two weeks, the gene expression and tissue characteristics of the skin of the cream-coated mice returned to a young state'Skin aging is not only the result of wear and tear, but also the result of a persistent lysing genetic process, ' Zhang saidPeople can block this genetic procedure to improve theof humanhealthAlthough it will take years to determine whether it is safe to apply this method to humans, the finding offers hope that, because the technology may be effective for any organ or tissue, humans could one day cure many age-relateddiseases
