Abstract:
NAT10 (N-acetyltransferase 10) is a protein with histone acetylation activity and primarily identified to be involved in regulation of telomerase activity. The presented research shows its transcriptional activation by genotoxic agents and possible role in DNA damage. NAT10 mRNA could be markedly increased by using hydrogen peroxide (H2O2) or cisplatin in a dose- and time-dependent way, and the immunofluorescent staining revealed that the treatment of H2O2 or cisplatin induced focal accumulation of NAT10 protein in cellular nuclei. Both H2O2 and cisplatin could stimulate the transcriptional activity of the NAT10 promoter through the upstream sequences from -615 bp to +110 bp, with which some nuclear proteins interacted. Ectopic expression of NAT10 could enhance the number of survival cells in the presence of H2O2 or cisplatin. The above results suggested that NAT10 could be involved in DNA damage response and increased cellular resistance to genotoxicity.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
