科学家们开始让基因工程小鼠的衰老细胞中有一个特定的分子。
The scientists started by genetically engineering mice to have a specific molecule in their senescent cells.
他表示，如果研究结果显示这并不与特定疾病相关，而却在全球有更广泛的影响，这将表明此类基因也许对延缓衰老起到基础性作用。
If it turns out there's no disease-specific relationship, but instead a more global influence, that would suggest these genes may have a fundamental role in slowing the aging process, he said.
支持这种关系的证据是需要修复的特定基因的损伤产生疾病例如加速衰老。
One line of evidence supporting the connection is that defects in certain genes needed for DNA repair produce maladies that mimic those of accelerated aging.
