*仅供医学专业人士阅读参考最近这一个月,围绕DNA修复的重磅研究非常多。10月中旬,同济大学团队发表在《科学》杂志上的论文显示,裸鼹鼠在进化过程中,替换了cGAS蛋白的四个氨基酸,将其从抑制DNA修复转变为增强DNA修复[1]。这也保证裸鼹鼠健康长寿 ...
本研究系统揭示了DNA双链断裂修复后的一个被长期忽视的层面:染色质结构与基因功能的不可逆改变。这种结构性与功能性损伤可稳定地传递给子代细胞,形成一种可遗传的基因表达缺陷,被作者定义为“染色质疲劳(chromatin fatigue)”。染色质疲劳为理解细胞老化、癌症发生、环境应激应答及基因编辑潜在副作用提供了新的理论框架,也提示未来在研究DNA修复及基因治疗时,必须同时关注三维染色质层面的长期影响 ...

After two decades in the making, scientists have cracked the code on a drug that can repair DNA, setting the scene for a new ...
The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...
When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...
