最近,澳大利亚国立大学(ANU)和德国海德堡大学的科学家们,发现了DNA修复过程中的一个重要组成部分,将为开发新的抗癌药物打开大门。相关研究结果发表在10月27日的《Cell》杂志。  


本研究资深作者、ANU副教授Tamás Fischer说,这项研究发现,由DNA和RNA组成的混合结构,对于DNA损伤后的遗传信息修复发挥着重要的作用。RNA是储存在DNA中的遗传信息的短暂副本。  

该研究还发现,靶定这些混合结构的RNase H酶,对于高效、准确的DNA损伤修复也至关重要。  
Fischer博士说:“这一发现为开发新的药物打开了大门,这些药物可以靶定这些酶、调节它们的活动,并阻止或提高这一重要DNA修复途径的效率。”  

他指出,人类基因组中积累的突变,是衰老相关疾病和癌症发展的主要驱动力。  
 
他说:“我们对这些修复途径了解的越多,就有更多的潜力来调节它们,并可能发展一些预防性方法,来减少各种突变的积累率。”  

“在分子生物学中,RNase H酶已经被研究和使用了很多年,但直到现在它们的生物学功能还不完全清楚。我们的研究表明,这些酶对于DNA修复是必不可少的,这可能是它们最重要的一个功能,因为它们存在于每一个活细胞内。”  

Fischer博士说,最令人惊讶的一个发现是,RNA - DNA杂交体,以前被认为只对人类基因组的完整性产生负面影响,这项研究发现,它实际上也参与了DNA的保护。  

DNA修复的细胞机制荣获了2015年诺贝尔化学奖(2015诺贝尔化学奖公布:DNA修复机制),科学家们一直没有停歇过对这个过程的探索。2015年十月二十八日在《Nature》杂志上发表的一项最新研究,发现了一类新的DNA修复酶。

2015年11月在《Nature Cell Biology》发表的一项研究中,加拿大阿尔伯塔大学医学及牙科学院的研究人员,探讨了DNA修复一个以前未知的秘密。

今年9月份,来自英国苏塞克斯大学的科学家发现了一种酶,称为PARP3,有助于促进DNA修复。相关研究结果发表在《Nature Communications 》杂志。
