查询词典 purified

Analysis of nuclear extracts of human cells has indicated a similar excision repair mechanism for nick-directed mismatch correction in higher cells, and several reconstituted systems that rely on purified human proteins have been described, such as hMutSα、hMutSβ、hMutLα. Recently, scientists discovered that nickel could be inhibitors of DNA repair. Nickel can greatly enhance the mutagenicity and genotoxicity of compounds in cigarette by inhibiting the nucleotide excision repair pathway in human cells. We have confirmed that nickel could inhibit MMR of E. coli and human and presumed that nickel inhibited repair before MutH incision of the MMR in E. coli. However, there is no evidence of mechanism of nickel inhibiting MMR in human cells.

镍是存在於香菸中的微量金属，近年来有学者发现镍是DNA修复反应的抑制剂，长期抽烟的人会容易因为香菸中化合物攻击DNA而引起突变，进而引起肺癌，而镍会抑制核苷酸移除修复系统（nucleotide excision repair；NER），所以使得体内的DNA损伤无法修复；过去实验室已经证实大肠杆菌的核酸配对错误修复系统会受到镍等重金属的抑制，并且推测出镍的抑制反应是抑制在修复反应的上游nicking的步骤；另外，也证实了人类的核酸配对错误修复系统也会受到镍的抑制，然而还没研究证实会抑制在核酸配对错误修复反应的哪个步骤。
