英文摘要
By using phosphorylation of histone H2AX as a marker of DNA lesion, we showed here that DNA double strand breaks were generated by several environmental genotoxic and carcinogenic agents including UV and DNA cross-linking agents. These agents also induced gene mutations through translesional DNA synthesis, which is associated with NBS1. NBS1 is also involved in phosphorylation of H2AX and chromatin-remodeling at sites of DNA damage. Thus, NBS1 plays important roles in genome stability (inhibition of tumorigenesis) through DNA repair and cellular response to DNA lesions.
