在中科院动物研究所，刘光慧和他的团队找到了“保持细胞年轻态”的分子开关，可以通过重设衰老的表观遗传时钟，使细胞老化的节奏放缓。据介绍，该团队确认了一个名为KAT7的新型人类促衰老基因。实验证实，将该基因在老年小鼠的肝脏中部分失活后，可使81%的小鼠年龄超过130周，而这约等于人类的80岁。

At the Institute of zoology, Chinese Academy of Sciences, Liu Guanghui and his team found a molecular switch to “keep cells young”, which can slow down the pace of cell aging by resetting the epigenetic clock of aging. According to reports, the team confirmed a new human aging promoting gene called kat7. It was confirmed that after partial inactivation of the gene in the liver of elderly mice, 81% of mice were over 130 weeks old, which was about 80 years old of humans.
